Aluminum forging has the advantage of the addition of deformation energy to further refine and improve the metallurgy of the shape being created. Through mechanical and thermomechanical deformation energy applied, originally cast ingots of aluminum are shaped and reshaped, changing the internal microstructure. Any inclusions or alloy concentrations are dispersed, and any voids are crushed and eliminated. Forging energy drives the recrystallization of the microstructure, creating enhanced durability and toughness. Forged aluminum is not usually able to produce shapes as complex as cast aluminum. This often requires additional machining operations which adds to the cost of using aluminum forging. The improved properties of forged aluminum product outweigh cost issues, however, when safety, reliability and the cost of component failure are the greatest challenges.

In summary, forged aluminum is strong, which is the ideal choice when aluminum components must exhibit maximum strength and performance in service, where weight is minimized. 

Drop forging is one of the oldest metal-forming processes that is still used as of this date.  
Did you know drop forging process is already 6,000 years old! Fascinating, right?

The art of the drop forging techniques dates to at least 4000 BC and earlier. The hot forging of metals all began in the land of Mesopotamia, between the Tigris and the Euphrates.

Bronze and iron went through the drop forging process by the early man to produce hand tools, weapons of war, and jewelry. However, the very first recorded metal, forged by fire and employed by humans was Gold. To shape the metal, rock was used as a drop forging hammer. Until the end of the 19th century, the precision drop forging of iron and steel continued.
Anodizing on Forged or Machined Aluminum Parts
In order to properly anodize forged or machined aluminum parts, the surface must first be cleaned and rinsed before getting placed into a bath of an electrolytic solution, primarily either sulfuric or chromic acid. This provides a electrically conductive coating that contains a number of positive and negative ions.  

So how does this process really work? Well, once the anodizing process is underway, a positive electric charge is sent through the aluminum, while a negative charge is applied to plates in the electrolyte. Basically, the electric current forces the positive ions to attract to the negatively charged plates while the negative ions are attracted to the forged or machined aluminum part, which the positive anode.

From here, the electrochemical reaction forces pores to open up on the surface of the aluminum so that the positive ions can escape. In a uniformly geometric pattern, these pores dig down into the substrate of the part. The combination of the aluminum surface and negatively charged ions create a barrier layer, which is known in the anodizing aluminum process as the surface layer the makes parts resistant to corrosion.

Drop Forging is becoming one of the most relied upon manufacturing methods due to its reliable quality and strength. Drop Forging is used in the production of a wide range of products that can be found in just about any industry or vertical you can think of.

When starting a drop forging project, there are a number of metals and alloys that can be used. Each of the alloys has unique physical characteristics that have benefits for different applications. It can be tricky to understand all of the mechanical properties, physical properties, and the compositions of different alloys, so it’s always a good idea to speak with an experienced drop forging company.

The automotive industry relies on drop forging for a variety of applications. Most automobiles have many metal parts that must be drop forged into specific shapes. Drop forging is the perfect method for making these parts. When choosing a metal for the drop forging process, steel or aluminum are often obvious choices. These metals are very strong and lightweight, making them ideal in the automotive industry.

At the same time, steel is one of the easiest metals to forge, and steel drop forging for automotive parts offers numerous benefits. Steel drop forging combines a high level of production efficiency, superior quality and cost-effectiveness. Here’s our guide to using drop forging for automobile parts, including benefits, applications and the drop forging process in the industry.
The automotive industry has greatly benefited from the forging process, specifically either hot or cold forging, thanks to their high-demand for complex shapes. Some specific forging parts used by the automotive industry include: engine parts, steering parts, automatic and manual transmission systems, etc.

Most of the automotive parts are made from forged steel or forged aluminum. Steel has always ruled when it comes to automotive production. Forged steel is strong and when you forge it, it becomes stronger yet. However, forged steel is heavy and tends to corrode with road chemicals. There has been a push of late to reduce vehicle weight and reduce corrosion on equipment caused by road chemicals. One solution to these problems is the more extensive use of aluminum components.
Aluminum Hot Forging
Aluminum in its elemental form is a fairly soft and lightweight metal and is commonly alloyed with copper, magnesium, tin or zinc to increase its strength, durability, mass and workability. About 85% of aluminum parts are made by forging. Aluminum alloys are easily forgeable. Cast aluminum products are relatively low-cost due to its low melting point, however they do have lower tensile strength. Common forged aluminum alloys include: 6061, 6063, 6082, 7075, etc. Aluminum alloys are widely used in engineering applications and components where lightweight and resistance to corrosion is required. Forged aluminum parts are used in aerospace projects, automotive engine components, shipbuilding and other saltwater sensitive applications. 

After understanding hot forging and cold forging methods, many people may still doubt the selection of forging methods of aluminum parts. Generally, cold forging is selected only when the shape of aluminum parts are simple and regular. Due to the expensive mold cost of cold forging, there is a high requirement on order quantity, normally above 30,000pcs. For irregular aluminum parts, hot forging is recommended, and most of the forged aluminum parts will be further machined to get finished parts. Both hot forged and cold forged aluminum parts could be heat treated and anodized when necessary. CFS Forge is professional on forging all types of aluminum parts. If you have any inquiry on forged aluminum parts, pls contact us timely!
Besides automotive forgings, aerospace forgings can also be customized in our drop forging company. Compared with drop forgings used in general machinery manufacturing industry, aerospace forgings have the following three characteristics:

First, aerospace forgings generally choose materials with high specific strength and specific stiffness, and often adopt new materials, constantly putting forward new and higher requirements for drop forging production technology.The application of materials depends on advanced forging technology and also promotes the development of advanced forging technology and equipment. Due to high strength and low plasticity, large forging equipments are generally needed, which have low deformation speed, good deformation temperature control. 

In drop forging process, stainless steel is one of the common forged materials. After forging, heat treatment is generally operated to release the stress and ease further machining job. CFS Forge, an experienced drop forging company in China, can customize stainless steel forgings with various heat treatment processes.

Austenitic Stainless Steel Forgings
Solid solution treatment: heating stainlesss steel forgings to solid melting temperature (1050 ~ 1100℃), making all carbide and cold processed Martensite melt into austenite, then fast cooling. This type of heat treatment can obtain the most soft and plastic effect.
Forged Rail Clip

A rail fastening system is the way to fix rails to railroad ties or sleepers. It is required to be reliable in connection, simple in structure, easy to disassemble, and also needed the properties of elasticity, vibration damping and insulation. Different types of sleepers have different rail fastening system for use with ballast and ballastless tracks. Railway fastening system for wood sleeper includes dog spikes and tie plate. Rail fastening system for concrete sleeper is generally rail clip type and balde-type. The most commonly used types are elastic clip fasteners with SKL, clip, e-clip, Nabla or KPO clamp, etc. Generally, rail fastening system is consist of screw spikes, rail bolts and nuts, flat washers, rail clip, gauge block, and rail rubber pads.

In railway fastening system, rail clip is one of the components which ensure that rails will be fixed to ground. Rail clips undertake rail movements synchronously thanks to synthetic elastomer vulcanized to clip permanently in the portion to be contacted with rail.
Rail clamp, also known as railway clamp, railroad clamps, sometimes called rail clip or rail fixing clip, is kind of device to be clamped on tracks to prevent the train from moving or passing a given point to the ground (as at platforms or on stub tracks) to avoid risks or dangers. Such rail clamps are always boltable, self-locking, adjustable with fine tolerance and high clip strength.

Drop Forging refines the grain structure of rail clamps and develops the optimum grain flow, which imparts desirable directional properties such as tensile strength, ductility, impact toughness, fracture toughness and fatigue strength. In addition, drop forged rail clamps are free from internal voids and porosity. The whole forging process achieves very consistent material uniformity, which results in uniform mechanical properties and a uniform, predictable response to heat treatment.

Aluminum forging is the common type that is easily accessible for its light weight and good strength. They are available in all shapes and sizes. Aluminium forging is not only easy but also quicker to establish. The net output is also light in weight and, hence, easy to carry around or transport compared to its rival counterparts. The strength of the produce through aluminium forging can also be controlled as per the maker's desire. They can be made subtle or strong depending on the need or end usage. Forged aluminum components have a direct strength to weight ratio so the manufacturer knows how much forging needs to be involved in order to gain the desired output. The best part about them is that they last for very long as they are rust-free and have high resistance against environmental changes, chemicals and toxic materials.

A lot of properties possessed by forged aluminum components make them favorite amongst aluminum forging companies. Compared to other metals, aluminium conducts heat effortlessly which other metals would not be able to do at the same given price. This makes it economic for users to opine for it. When it comes to power consumption, again, forged aluminum components are given a higher preference compared to other metals since they conduct electricity very well and are more efficient.
Brass Forging for Water Meter Fittings
A water meter is a device that measures the volume of water delivered to a property. Some water meters measure water in gallons while others measure in cubic feet. The brass water meter fittings are commonly used for connecting to a water meter installation, but can also be used to connect network elements or other accessories provided with threaded connection. 

Normally such water meter fittings are designed and produced by brass hot forging and machining. According to the drawings or samples from our customer, CFS Forge can forge and machine water meter brass fittings in different sizes.The brass hot forging process offers many advantages in comparison with the traditional casting techniques. Any inquiry on brass forged and machined water meter fittings, pls feel free to contact us! 
3 Reasons to Choose Drop Forging
The usual drop forging process has changed a bit over the years from when blacksmiths hammered hot metal against an anvil or something akin to that to shape the metal into a requested item. But drop forging in general has not actually changed much. Drop forging is still done with the same basic philosophy, that is, pound heated metal into a shape. And while people still forge metal by hand, and not all forging is done with heated metal, the drop forging process has become increasingly mechanized as new forms of technology have developed.

There are so many ways to forge metals, and each of these methods have their own peculiarities; One very well named metal forging method is called drop forging. Drop forgings are performed when a person inserts a sheet of metal into the press. This sheet is placed over top of a die, the shape of which is based on whatever has been ordered or what the company has decided to produce that day. Once the metal is securely in the machine, a hammer comes down, or rather drops down, and forces the sheet of metal to take the shape of the die. The hammer itself is called a power or drop hammer – hence the name drop forging – and they usually only need to be dropped on the metal once to get it to the right specifications.
When talking about drop forging, people are always impressed on the higher quality than that of investment casting. The parts created by drop forging process are tough, strong and finely-shaped, which are used in a wide range of applications, most widely are automotive, forestry, oilfield, etc. Steel, aluminum and copper are the the most common metals in industries get the appeal and strength through drop forging process. Apparently, drop forging manufacturers in China, like CFS Forge, make a metal stronger than the original raw material. And it also gives the metals high level of durability.

Drop Forging also grains the metal which makes it last longer and remain continuous for a lifetime. In most of the industries, a specific shape of metal is required for a specific application. Getting this shape is not possible without drop forging. So drop forging is also advantageous in giving metals different shapes and converting them into different final products. These well-shaped metals are then used for a wide range of applications.

When designing a drop forged part, aluminum and brass are the common forging materials to consider. The same point between forged aluminun and forged brass is that they are all made from drop forging, which can creat metal parts with great strength, close tolerance and good surface finish. Meanwhile there exsits differences between these two types of forging materials. Before making a decision, it is important to understand the differences between forged aluminum and forged brass.

Althought the forging process of aluminum and brass alloys are almost the same, there still exsits great differences between forged aluminum and forged brass. As the professional drop forging company, we can produce both forged aluminum parts and forged brass parts.
Due to the high quality of drop forgings, the quality control system and process discipline in the drop forging factory are relatively strict, and the quality control means are also relatively complete. The quality control is mainly reflected in three links. Firstly, the raw materials are reinspected to check whether their chemical composition and physical properties meet the technical requirements. Secondly, strictly supervise the production process to meet the quality requirements. Thirdly, check and accept the finished drop forging according to the quality standard.

The production process discipline of drop forgings must be strict, especially for forged steel aumotive parts . Once the process rules are determined, they must be strictly implemented and cannot be modified without approval. This is another aspect of quality supervision in the workshop. In view of the above requirements, there are many inspectors in the drop forging plant. Depending on the composition and nature of the workshop, inspectors shall be approximately 5% of the total workshop workforce.
Forged Steel Automotive Parts
Forged steel is nothing but the forging process of giving steel billets to different shapes as per the drawings of the final products. There are several processes for forming a component by forging. The most commonly used metal for automotive components is steel. For all such products, steel billets are cut into the required lengths and weight, heated up in an intermediate frequency furnace, then forged into the desired shape with the workforce of dies on a forging press. The part is then forwarded to another press machine to remove the trimmings under trimming dies, finally, sent on to the machining line for finishing into the final product. 

Forged steel can creat automotive parts stronger than equivalent types that are cast or machined. Steel forging is commonly used in automotive applications due to its strength, availability, and high quality. Forging in steel offers unsurpassed resilience for manufacturing automotive parts that simply do not fail. There are several benefits of automotive parts in forged steel:
  • By drop forging process, it can creat forged steel automotive parts with close tolerances, and less or no machining is required, which can help to save cost.
  • Compared with casting or machining, automotive parts in forged steel are free from defects such as gas voids, pockets, or cooling defects which can lead to load failure.
  • Under the high pressure of forging dies, the internal crystal structure is improved, which will grearly improve the strength of automotive parts, thus to make the serving life longer.
  • Normally, a pair of forging dies can forge out 20,000pcs~30,000pcs automotive parts, this capacity can support large volume order. What's more, the dies cost is charged only once in CFS Forge, will not be charged again for furture orders.

Type 6061 aluminum is of the 6xxx aluminum alloys, in which magnesium and silicon are the primary alloying elements. The second digit indicates the degree of impurity control for the base aluminum. When this second digit is a “0”, it indicates that the bulk of the alloy is commercial aluminum containing its existing impurity levels, and no special care is needed to tighten controls. The third and fourth digits are simply designators for individual alloys (note that this is not the case with 1xxx aluminum alloys). The nominal composition of type 6061 aluminum is 97.9% Al, 0.6% Si, 1.0%Mg, 0.2%Cr, and 0.28% Cu. The density of 6061 aluminum alloy is 2.7 g/cm3 (0.0975 lb/in3). 6061 aluminum alloy is heat treatable, easily forfged and machined, and is good at resisting corrosion.

6061 Aluminum alloy are generally forged by drop forging manufacturer on hydraulic presses because of their high strain-rate sensitivity. The use of hammers and mechanical presses are the exception rather than the rule. Ram speeds are generally on the slow side, with 1 inch/second or less being typical. Hot dies, including isothermal, are common. In most cases, the tooling temperature is within 250°F of the workpiece temperature. For net-shape/precision forgings, isothermal tooling and low strain rates are the norm.
6061-T6 forged and machined aluminum part
Aluminum alloys, for its low density, can always be used to make metal parts with light weight. Generally, aluminum alloys are divided into casting alloys and forged alloys, and are best suited for different applications. Forged aluminum alloys, such as the 6061 alloy, are widely used in drop forging process to creat specified shapes and dimensions. During the process, the billet is heated through an induction furnace and forged using a closed die drop forging process.  

Among all the forged aluminum alloys, 6061 is one of the most commonly used aluminum grades in the world. Whether hot or cold forging, 6061 is the choice for a wide range of applications, including automotive, motorcycle, aerospace, and so on. So, what makes 6061 so versatile? Like with any grade, it starts with the makeup of the metal. Its major alloying elements are magnesium (1.0%) and silicon (0.6%). This makes it highly resistant to corrosion, stress, and cracking. This also means the grade features good formability and weldability. Pls note 6061 is not an alloy that is traditionally cast due to its low silicon content affecting the fluidity in casting. 
Drop forging is the metal forming process that shaping metal and increasing its strength. In drop forging, an upper die is forced against a heated workpiece placed on a stationary lower die, and the billets will fastly filled the cavity of dies under the workforce of high pressure. Then, the billets become a forged blank that has the desired shape as designed. Finally, remove the flash under trimming dies to achieve a net shape drop forged part.

Typical metals can be drop forged include: steel alloys, copper alloys and aluminum alloys, among which aluminum alloys are the lightest. So aluminum forgings are gradually replacing steel forgings, especially for automotive and aerospace industries. Customer may doubt the section of drop forging for aluminum alloys, as the professional drop forging company, here we would like to introduce in detail.

First of all, you should understand the charteristics of aluminum alloys. Aluminum is a metal similar to steel, brass, copper, zinc, lead or titanium. It can be melted, cast, forged and machined in a similar way to these metals and conducts electric currents. Aluminum is a very light metal with a specific weight of 2.7 g/cm3, about a third of that of steel. This cuts the costs of manufacturing with aluminum forgings. Again, its use in vehicles reduces dead-weight and energy consumption while increasing load capacity. This also reduces noise and improves comfort levels.
how to choose the best drop forging company
On the internet, you will find many numbers of companies that can provide drop forging service. For your RFQs, you may contact several potential drop forging suppliers for comparision. Besides comparing prices from these different drop forging companies, it is also a process for you to understand and choose a best drop forging company. 

Drop Forging is a manufacturing process that squeezes heated round bars between upper and lower dies until filling the cavity of dies completely. Parts produced by this method are of precise sizes, little or no machining allowance and complex structure with high productivity. Drop forging process has high production efficiency and low labor intensity, which will be able to make complex components with higher strength than casting process. This production method is suitable for mass production. However, the cost of forging dies is relatively high, not suitable for single piece or small batch production.
By employing drop forging process, metals (steel, aluminum or copper) can improve its structure and mechanical performance. The drop forgings are deformed by hot processing. Owing to the deformation and recrystallization of the metal, the original coarse dendrites and columnar grains become equiaxed recrystallization with finer grains and uniform size, then the original segregation, looseness, pores and slag inclusions in the ingot are compacted and welded and their structure will become tighter. The plasticity and mechanical performance of the metal are further improved.

In general, the mechanical performance of castings is lower than that of forgings with the same raw material. In addition, the forging process can ensure the succession of the metal fibers and keep the forged fibers consistent with the shape of the forged pieces. What’s more, the metal streamlines are intact, which can ensure the parts have outstanding mechanical performance and long working life. With the process of precision die forging, cold kneading and warm kneading, forgings are more superior than castings in performance.
As the most widely used non-ferrous metals, the output of aluminum and aluminum alloys is second only to steel. In terms of the amount of deposits in the earthcrust, aluminum accounts for about 8.13% of the quality of the earthcrust, which is more than double the amount of iron and more than the sum of other non-ferrous metals. The density of aluminum alloy is only one third of that of steel (the density of aluminum alloy is 2.7g/cm3 while the steel is 7.85g/cm3), thus aluminum alloy is a perfect lightweight material. It is suitable for critical load-bearing workpieces with lightweight owing to its great strength and stiffness as well as high fatigue strength. Aluminum alloy has significant plasticity and can be processed into various high-precision forgings with complex shapes. Aluminum forgings have characteristics of corrosion resistance, thermal conductivity and non-magnetic, which is more superior than steel forgings.

Aluminum forgings have been widely used in various fields such as machinery, aviation, automobiles, railway vehicles, ships ,marine vessles, buildings, bridges, chemicals, and power owing to their excellent properties. By replacing steel forgings with aluminum forgings, it can greatly reduce the weight of mechanical products and increase the structural stability. Therefore, aluminum forgings are essential components in the fields of aviation, aerospace and many defense industry sectors. For example, there are many aluminum forgings used in aircrafts ,which accounts for 15% -50%.
anodized aluminum forgings
Anodizing uses acid to create a corrosion- and wear-resistant layer on the surface of aluminum forgings, which is one of the common surface finishes on forged aluminum parts. The process of anodizing also changes the crystal structure near the surface of aluminum forgings, which allows you to dye the forged aluminum part a bright color. It protects against corrosion, enhances aesthetic qualities, resists scratching and is one of the most durable surface finishes available after aluminum forging.

There are several color options for anodized aluminum forgings, taking forged aluminum brake lever for example, one of our customer needs 5 colors: silver natural, black, red light, blue and light grey. This multi-colored anodized aluminum forgings are available from CFS Forge. After coloring, anodized aluminum forgings have a characteristic “metallic” look. This is caused by two factors. One, because of the uniform electro-chemical etching, a rough surface is left behind. The deeper the pores, the rougher the surface will be but the colors will also be that much more durable. Secondly, light striking the surface partly interacts with the colorant and partly with the uncolored metal at the top. So the light that bounces back to strike your eye will in fact be a combination of two distinct wavelengths interacting as they reflect from slightly different surfaces. This causes the distinctive shine of anodized aluminum forgings.

What is forged brass and where is it commonly used? In a nutshell, forged brass is an alloy of copper and zinc that is heated up to 900 degrees Fahrenheit before it is squeezed into shape in precision-machined closed die presses. This gives the resulting material more tensile strength as compared to its molded counterparts.

Depending on the amounts of copper and zinc used, the resulting alloy can provide varying degrees of electrical and thermal conductivity, corrosion resistance, ductility and machinability. The unique metal combination can also determine its joining and plating characteristics, non-magnetic and non-sparking properties and its polishing and finishing characteristics as well.
Aluminum is one of the common materials used in drop forging process, where you basically heat and squeeze the aluminum material until the shapes of parts are formed. Aluminum hot forging is commonly used for manufacturing automotive suspension parts. You get geometrically complex parts with excellent mechanical properties and tight tolerances. It is competitive as a manufacturing process for light-weighting suspension parts for cars.  After forging, both the strength and mechanical properties will get improved, which makes forging a competitive process for automotive suspension parts.

Why suspension parts? Several reasons. One is that suspension parts are generally dimensioned for dynamic fatigue loads. And any adverse surface quality will impact the fatigue lifetime of the suspension. Another reason is that suspension parts forged from aluminium are the lowest-weight suspension parts in industrial scale use, and weight is particularly important in a vehicle’s unsprung mass. Furthermore, they provide better vehicle response, since the inertia of the parts are reduced, and they lessen the noise from the chassis, which gives you a more comfortable ride. Lastly, by using aluminium, the reduced weight helps you save emissions.

Due to the multi brands of cars and other vehicles, there are a variety types of ball joint housings that can meet different ball joint connecting. Generally, according to its application, ball joint housing is designed and produced by forging with steel.

Forging of ball joint housing is a hot die forging process, which begins with a heated billet which gets “squeezed” in dedicated dies where its grain structure is broken down and homogenized into finer grains for increased yield strength and ductility. Because the steel is hot, it gets easily deformed and allows drop forging manufacturers to create more elaborate shapes than with cold forging. The fact that the ball joint housing is plastically deformed above its recrystallization temperature, allows it to retain its deformed shape as it cools.

The forgings of wheel hub type are often made by means of drop forging processes realized on presses. Due to the necessity of lightweight structure, wheel hubs are often manufactured by aluminum forging. Forming of drop forged wheel hub is a specific hot forging process and it differs from steel forging process.

The big changeability of aluminum alloys properties within the range of the applied forming parameters results in difficulties in the process design. The majority of aluminum alloys’ forgings are made by means of forging process with flash. The degree of complex forging geometry decides about the amount of heating and type of the applied tooling. The forgings with a complex geometry, ribbed, which need a precise preforming, are forged in preforming impression, and next, after the damages removing and reheating they are forged in forming impression. In the forming process of less complex forgings, which are made in small series, the application of preforming impression is usually omitted. Preforming operation is made in forming impression with several  millimeters of underfilling. After the damages removing and reheating, it is finally made in the same impression. In case of enlarged forgings, the preforms are rarely used despite difficulties in their obtaining. For the preforming of material, enlarging and rolling impressions are not applied. The operation of this type causes fast lowering of material temperature and the overlapping creation as a result forging with rotation at the same time. Because of that, workpiece in the form of a bar with the section close to the biggest forging section is used.

It has been proved that forged aluminum alloy is a perfect option compared to steel forgings and cast aluminum parts in the competition for reducing vehicle weight. Additionally, this choice leads to a decisive productivity improvement in the high-volume production under competitive price levels.

In terms of automotive chassis, the light weight of inelastic materials is beneficial for safety and comfort. Heinz Lowak, a doctor of engineering, argues that before he put the box with the silvery lateral guides for the front axles of the Audi A6 and Volkswagen Passat: "Our aluminum forgings weigh only half the weight of the same functional steel components, which is a decisive advantage." Meinertzhagen, the light metal technology sales and marketing department head of the Otto Fuchs company believes that aluminum can achieve very good mechanical properties through forging. The tensile strength and yield limit of the above lateral guide can reach 440N/mm2 and 380 N/mm2 respectively, the elongation can be more than 10%, especially for the yield limit and elongation, the level of aluminum forgings is higher than the commonly used cast aluminum alloy.
drop forged yoke ends
Drop forging of yoke ends is a method of shaping and forming metal using a set of dies (metal-shaping molds). Downward force is applied by the second moving part of the die. This downward force and motion is where the "drop" in drop forging comes from. As the most common metal forging method, it is very suitable to produce yoke ends.
The strength of yoke ends made by drop forging manufacturers can be greatly improved, which is for its particular use by causing the internal grain of the metal to deform to follow the shape of the part. Besides carbon steel, yoke ends can also be drop forged by other metals, such as stainless steel or aluminum. In short, drop forgings are used often to produce hardwares for industries such as aerospace, national defense, automotive, agriculture, construction, hardware, mining, material handling, etc. Many hand tools have “Drop Forged” boldly imprinted on them to indicate their added strength and durability as a result of the forging process. If you have any inquiry on drop forged yoke ends or other drop forged components, pls contact CFS Forge now!

chinese aluminum forging supplier
Generally, there are two kinds of forging methods of aluminum alloys, namely aluminum hot forging and aluminum cold forging. The difference between aluminum hot forging and aluminum cold forging is the deformation temperature. All the aluminum forging parts made in CFS Forge is closed die hot or cold forged. Closed-die forging is able to shape aluminum material into a wide array of shapes, designed within fairly precise tolerances. This process is a useful way to form small precise aluminum parts. When it comes to large production runs, closed-die forging typically remains more cost-effective than casting method.  Moreover, closed-die forging offers a better surface finish and is more environmentally-friendly.

Compared with aluminum forging companies from developped countries, the manufacturing cost of aluminum forging parts in China is much lower. To save cost, many overseas companies choose to import goods from Chinese aluminum forging suppliers. As one of the largest aluminum forging companies and exporters in China, CFS has the capabilities of forging, machining, surface polishing or anodization of aluminum alloys, which will enable us to supply finished aluminum forging parts to our customers from USA, UK, Canada, South Africa, etc. According to our rich experience in aluminum forging field, here are some attentions to pay to when choosing the right Chinese aluminum forging supplier.

Forging is one of the main manufacturing ways to provide metal blanks for mechanical parts to various industries. The advantage of forging production lies in: it can not only obtain the desired shape, but also improve the internal organization of materials and mechanical properties. For the important mechanical parts with large force and high mechanical performance requirements, most of them are made by forging. Forging parts account for 80% of aircraft parts, 70% of tank parts, 60% of automobile parts. Hydraulic turbine spindle, impeller, rotor, ring guard, etc. in the power industry are all forged.It can be seen that forging production occupies an extremely important position in the industrial applications.

Forged aluminum has the advantages of low density and high strength, so it has been widely used in various industries. Aluminum forging is becoming the main production process of various mechanical parts. Generally, any part forged with low carbon steel can be forged with aluminum alloy in aluminum forging companies. Forged Aluminum parts in various forging equipments such as forging hammer, mechanical press, hydraulic press, die forging, rolling forging and die forging. Generally speaking, aluminum forgings with small size, simple shape and wide tolerance requirements can be easily forged on the forging hammer, but for aluminum forgings with large specifications and severe deformation requirements, hydraulic press is used for forging. Aluminum forgings with large and complex integral structures must be produced by large hydraulic die forging press. For large precision ring parts, precision ring rolling machine should be used for rolling forging.

With the characteristics of low density, moderate strength, corrosion resistance, easy shaping, easy welding, beautiful appearance, durability and easy recycling, aluminum alloy should attract more and more attention in motorcycle industry and its applied range should be expanded in the motorcycle industry. In the 21st century, aluminum alloy motorcycle parts should be vigorously developed based on the above advantages.

Almost all steel parts on motorcycles can be replaced by aluminum alloy materials under the continuous efforts of the related professional and technical personnel in motorcycle industry. In recent years, with the increasing demands of international environmental protection and national and regional government energy conservation regulations, motorcycles are moving toward a tendency of “green motorcycle” that is lightweight, high-speed, safe, comfortable and environmentally friendly. Undoubtedly, it will promote the application of aluminum alloy materials on motorcycles. Forged aluminum alloy is particularly important in its material application.

When it comes to aluminum forging, the most atttactive word is "aluminum". We all know that aluminum becomes more and more popular in forging for its light weight compared to steel and brass. When buyers send a drawing of forged aluminum component to an aluminum forging supplier, the material specification (aluminum alloy) is already clearly marked in the bottom of the drawing. The material selected for aluminum forging will determine the final performance of products. So, it is quite vital to select a suitable alloy before manufacturing.

As a professional drop forging company, CFS Forge has many years' manufacturing and exporting experience in forged aluminum parts. We can supply aluminum forging and machining services with various aluminum alloys. If you are looking for a supplier for your aluminum forging project, pls contact us!

The traditional application of forged aluminum is mainly concentrated on sports cars or vehicles with low fuel consumption. The components produced include pistons, rims, valve shifter levers, suspension parts and other important structural force parts. The production cost of forged aluminum parts increases due to the high material cost and complicated manufacturing process, which hinders the applications of forged aluminum parts. At present, many countries such as USA, Canada, Australia, South Africa, etc are actively researching and developing high-strength materials as well as forging processes so as to reduce the production cost of forged aluminum parts.

CFS Forge is the professional aluminum forging company for custom forged aluminum parts in China. Just pls contact us if you have any forged aluminum project.

Vehicle weight reduction is essentially the lightweight of automobile parts. With the forged aluminum alloy wheel hubs, it can greatly reduce the weight of the auto body. For instance, a 40-ton heavy-duty truck and semi-trailer transport system has a total of 22 wheel hubs. It will has 24 wheel hubs if the front and rare spare tires are considered. The vehicle weight will be reduced by nearly 600kg if we replace the frequent used steel hubs with aluminum forged ones. What is more, aluminum alloy materials have good heat dissipation, which can slow down the aging speed of tire rubber to a certain extent. Trucks, buses and trailers equipped with forged aluminum alloy wheels can save 26% of tire consumption.

A plenty of commercial vehicles are equipped with aluminum forged wheels in America and Canada. This also occurs in Europe, South Africa and Australia. Along with the development of China's automobile lightweight technology and the rising fuel prices in recent years, the replacement of traditional automobile wheels with aluminum alloy wheels has become a trend. As a professional drop forging manufacturer, we would like to describe a practical closed die forging process of aluminum alloy wheel hub, by using UG three-dimensional modeling, the forgings are designed and then the wheel hub closed tooling formwork is designed. Then the 3D model is imported into the Deform simulation analysis software to conduct the forging simulation. Based on the analysis of the simulation process, the blank displacement, the filling degree of the material as well as the temperature distribution, the forging general process is preliminarily obtained.

There are usually four kinds of defects caused by improper forging process of aluminum alloy:

1. Large-grained
Due to too high initial aluminum forging temperature and insufficient deformation degree, or too high final forging temperature, or deformation degree fell into the critical deformation zone. Aluminum alloy deformation degree is too large, forming texture; Superalloy deformation temperature is too low, the formation of mixed deformation microstructure may also cause coarse grains.

The ductility and toughness of aluminum forgings will be reduced and the fatigue performance will be obviously decreased. Uneven grain size: refers to the fact that the grain size in some parts of the forging is particularly large and smaller in some parts. The main reason for the unevenness of grains is that the unevenness of deformation in different parts of the blank results in different degree of grain breakage, or the degree of deformation in local areas falls into the critical deformation zone, or the local processing hardening of superalloy, or the local coarse grains in quenching.Heat resistant steels and superalloys are particularly sensitive to uneven grain size. The unevenness of grain will obviously decrease the endurance and fatigue performance of aluminum forgings.

For the closed-die forging of aluminum components, die or mold is critical element in the overall aluminum forging process, because the dies are a major element of the final cost of such forgings. Further, forging process parameters are affected by die design, and the dimensional integrity of the finished forging is in large part controlled by the die cavity. Therefore, the forging of aluminum alloys requires the use of dies specifically designed for aluminum because:
  • The deformation behavior of aluminum alloys differs from that of other materials; therefore, the intermediate and final cavity die designs must optimize metal flow under given forging process conditions and provide for the fabrication of defect-free final parts.
  • Allowances for shrinkage in aluminum alloys are typically greater than those for steels and other materials.
  • Temperature control of the dies used to forge aluminum alloys is critical; therefore, the methods used for die preheating and maintaining die temperatures during forging must be considered in the design.

Pipe fittings are the fittings used in the piping systems to connect the straight pipe or tubing sections, adapt to different sizes or shapes and for other purposes, such as regulating (or measuring) fluid flow. Pipe fittings can be designed and made in different kinds of metal materials, including steel, aluminum and brass. Compared with steel and brass pipe fittings, aluminum pipe fittings can offer light weight but good corrosion resistance. 

Aluminum forging for pipe fittings are the hot forging process that pressing aluminum billets into shapes of various pipe fittings. There are several steps involved in forging aluminum pipe fittings, including billet cutting, billet heating, forging, trimming and shot blasting. To achieve qualified production, each step of manufacturing pipe fittings during the aluminum forging process must be strictly controlled. As the professional aluminum forging company in China, CFS Forge is able to supply custom aluminum forging and machining service of various pipe fittings for our customers. If you have any inquiry on aluminum forged pipe fittings, pls contact us.

Besides the control of aluminum forging temperature, the design of aluminum forging component is also very important. Parts design mainly includes the standards for machining allowances, parting line location, draft angles, corner and fillet radii for the aluminum forging.

Machining Allowances

Recommended machining allowance for aluminum forging is given in below Table.


Minimum Finish Stock per 
Less than 200
200 to 400
400 to 600
600 to 900
More than 900

As shown above, the allowance is referred to as minimum finish stock per surface and is related to the largest dimension of forging. Machining allowance may be applied over the entire forging or to the surfaces to be machined. The finish allowance is applicable to all metals.

Most of the aluminum forgings are produced under hot forging condition. During aluminum forging process, the temperature used is a critical factor, which should be controlled strickly, higher or lower temperature will all easily cause forging defects. Before forging, aluminum alloy billets are heated fairly below their solidus temperature, because the heat generated during forging deformation will also cause a temperature rise in the material. If the heated billet temperature and the temperature rise during drop forging exceed the melting temperature of aluminum alloys, the aluminum billets will start to melt, and severe cracking of forgings will be seen. This effect is mostly significant in high-speed forging, such as on a mechanical press or forging hammer, because the heat generated has little time to diffuse into the dies. This reduces the complexity of the shapes that can be produced on high-speed forging equipment and potentially increases the amount of machining required.

On the other hand, with the temperature increase of aluminum billets after heating, the forgeability of all aluminum alloys will also be improved. As the forgeability of each aluminum alloy is different, the heating temperature required during hot forging process is also different. Below picture shows forgeability of different aluminum alloys with respect to temperature changes are given. From this picture we can well see that as the temperature increases forgeability increases. 
As you know, forging is better for applications. 6061 and 7075 are the two common used alloys in aluminum forging. When it comes to 6061 aluminum alloy or 7075 aluminum alloy for a forging project, it is necessary to understand their differences and applications. It saves you trouble when looking to balance performance with cost. For most general purposes, both alloys can get the job done. But the differences in composition, mechanical properties and cost can help you choose what fits your forging needs best.

The chemical differences between 6061 and 7075 aluminum forgings aren’t readily visible. Both contain magnesium, silicon, copper, iron, zinc, titanium, manganese and chromium. The difference is how much of each is contained in each. 6061 aluminum forging contains less zinc than 7075. Meaning that while 6061 aluminum forging provide superior welding abilities and workability, it doesn’t boast the same high strength and stress resistance as 7075. Looking for a good aluminum forging company in China for your item?

Because aluminum forging is a customize and professional service, aluminum forging experience will help a lot in communication and avoid misunderstanding in engineering. it will save lots of time and cost. When you decide to work with one aluminum forging manufacturer, I suggest to visit them on site, then you can check their facility and talk to them face to face. if time or budget is limited, then you can ask for some reference customers from your own country who are dealing with them, the people who live in the same country and culture are always more trustworthy.
aluminum forging of tee

Tee is also called pipe fitting tee or tee pipe fitting, tee joint, etc. It is mainly used to change the fluid direction, as in a branch of a main pipe. It can be sorted by pipe diameter. Tee can be made in various materials, such as carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon rubbed li, PVC and so on.

Utilizing the plasticity of the aluminum alloy, the forgings with required shape, size and certain microstructure properties can be obtained by shaping deformation with the help of external forces. After forging with aluminum alloys, we can achieve good strength, uniform structure and no internal pores. Besides, T6 heat treatment and anodic oxidation can be operated to improve its mechanical properties and avoid oxidation.
factors to consider during hot forging process

As the name suggests, the process of hot forging requires the heating of the metal, so the heating temperature has a significant impact on the forming process and result. In order to ensure the forgability of the metal and obtain good internal structure performance, the forging heating must follow certain heating specifications and carry out the forging process within the specified temperature. At the same time, because the temperature of the blank metal is very high, sometimes the mold also needs preheating, so there are certain requirements for the life of the mold and forming equipment. In order to ensure the progress of the forging process, the following major issues need to be considered during hot forging process:

In hot forging, the metal blank is heated to a certain temperature before forging. Can reduce the strength of the metal limit b sigma, improve its plasticity, and the higher the heating temperature, the greater the b sigma reduction, the required forming force is lower. In order to reduce the forming force and energy consumption, the heating temperature of the metal blank should be raised as far as possible on the premise of avoiding the occurrence of overburning of the metal. As the aluminum forging temperature range is narrow, so we should pay more attention to the control of pre-forging heating.
In the process of forging, not only the appropriate shape and size must be required, but also the performance requirements of the parts during the use must be met, which includes strength index, plasticity index, impact toughness, fatigue strength, fracture toughness, resistance against stress corrosion and so on. This makes forging process always better than other metal working processes. 

compared with other processes (casting or machining), forging is always better. CFS Forge is the professional drop forging company, we can deal with drop forging process with different materials: steel, aluminum and copper. Contact us if you have any forging source from China.
An attractive combination of strength and formability, corrosion resistance and recyclability has made the age-hardening EN AW 6082 one of the most popular aluminium forging alloys. 6082 aluminum forgings are thus used extensively in automotive suspension components and other applications. The conventional manufacturing cycle starts with the casting of 6082 billets that are subsequently extruded into smaller diameter forging stock. The relatively higher temperatures generated by frictional heating and high strains introduced at the surface during extrusion encourage recrystallisation and produces a heterogeneous structure with fully recrystallised small grains at the surface, fibrous grains at the centre. Hence, the surface of the forged 6082 components inevitably undergoes grain growth once exposed to high temperatures during the solution heat treatment. An attempt was made in the present work to identify an alternative process to achieve a homogeneous section structure with no evidence of coarse grains across the section, which in turn will ensure a better fatigue performance and a longer service life.

CFS Drop Forge can make all types of aluminum forgings in different alloys, including 6061, 6063, 6082, 7075, ect. We can make 6082 aluminum forgings with both polished and anodized surfaces. Looking for a good aluminum forging company in China to forge your aluminum parts? Pls contact us!
brass forging for ball valve body
Brass ball valve bodies are created using a forging method that involves shaping metals and alloys while they’re in their solid form. Heat and industrial-size tools deliver compressive forces to bend the metals and alloys, and dies are used to cut and shape the materials to create specific valves. Forging can be performed in most temperatures depending on the brass used. Forging ball valve bodies presents many benefits for industrial companies. For example, companies don’t have to worry about wasted materials. Since forged ball valve bodies are shaped into one solid piece, little effort is needed to rework the material to achieve the proper shape and size. Forged ball valve bodies have a reputation for being strong, which make them ideal for handling high-pressure and high-temperature systems. During the brass forging process, the metal’s grain structure becomes more refined. This leads to an increase in impact and overall strength. Also, forging boosts its resistance to common issues such as cracks, shrinkage, and porosity.

On top of that, brass forging can create ball valve bodies with less wall thickness. This helps to reduce the likelihood of thermal fatigue during valve operation. This also means that forged brass ball valve bodies can be heated and cooled more quickly, which allows them to adequately handle the stresses of systems that continuously cycle through start-up and phase-down processes. Would like to source a brass forging for your ball valve bodies or other valve components? Pls contact us for your RFQs?
Since the brakes are frequently used during the motorcycle moving, the motorcycle brake calipers often receive the hydraulic pressure transmitted by the brake master pump as well as the reaction force of the brake pads to the brake calipers. Meanwhile, the calipers will also be repeatedly affected by the high temperature generated by the brake pads’ frictional heat. The common motorcycle brake calipers are generally made of cast aluminum alloy. Although the high temperature and pressure during braking will not cause the motorcycle brake calipers to be destroyed due to the metal fatigue strength, there will be some deformation, which will lead to a decrease in braking performance and a series of problems, such as brake imbalance. Therefore, the motorcycle brake caliper will be more durable with the aluminum forging process. Its advantages include: high strength forging process, excellent performance, lighter weight, higher temperature resistance and wide applicability. But the calipers can also be made by casting with the advantages of low price and the mature process, and it can meet the daily use, while its performance is common and its quality is heavier and was widely used in the original production car.

Usually, the motorcycle brake caliper is made by the process of casting or forging. In short, the mechanical strength of the motorcycle brake caliper with the aluminum forging process is higher than that of the aluminum casting, but the price of the casting caliper is relatively low, which has a direct relationship with the manufacturing cost.
                              drop forged ball mounts
The Drop Forging Process, also referred to as Closed Die Forging, is a process that manipulates hot metal completely within the wall cavity of two dies. The impression for the forging can be in either die or divided between a top and bottom die. The drop forging process can improves the strength of ball mounts by aligning the grain along the lines of potential stress, which cannot be achieved through casting, machining or fabrication. So, drop forging is always used to produce metal components like hitch ball, ball mounts, ect by our customers trailer towing application.

Drop Forged Materials selected to produce ball mounts can be either forged steel or forged aluminum. Forged aluminum ball mounts for trailer towing can achieve light weight, but due to the higher material cost, the price of drop forged aluminum ball mounts will be higher than that of drop forged steel ball mounts.

As a comprehensive drop forging company, CFS Forge can supply custom service for both steel forgings and aluminum forgings. So, no matter it is forged steel ball mounts or forged aluminum ball mounts, we will be all able to supply in competitive prices.

Forged Aluminum Hitch Ball Mount for Trailer Towing
The most important factor to consider the forging material for hitches and ball mounts is their propensity to rust. A great way to avoid this is to use aluminum as the material. Besides, aluminum forging can offer less weight for hitch ball mount than steel forging. Also, with aluminum forging, there is no need to worry about oxidization, which is helpful if you’re frequently changing ball mounts or working in close proximity to saltwater or road-salt. What's more, polishing can be operated after forging, which may improve the appearance of your towing vehicle. Therefore, Aluminum forging is a great choice for light-duty towing or hauling a bike rack, cargo carrier or small dinghy.

To lower the production cost, many buyers from USA, UK, Canada, Australia prefer to customize their forged aluminum hitch ball mounts for trailer towing from China Manufacturers. But unlike steel forging, there are few aluminum forging companies available for such forged aluminum hitch balls, especially when there is polishing requirement after aluminum forging. CFS Forge is the right China company can offer custom forging for aluminum hitch ball mounts. We have forging equipments for aluminum forged components in different tons, so no matter how large or small it is, we can all follow your requirements.
Aluminum forging is the forging process that shaping aluminum billets into required dimensions under the workforce of forging dies. This process can be operated either under the condition of hot temperature or room temperature. 

The common material used for forging aluminum wheel lug nuts is 6061-T6 or higher grade 7075-T6. Before forging, manufacturer needs to order the material with certain diameter according to the dimensions of wheel lugs. Meanwhile, design and making forging dies following the exact drawing. A pair of forging dies for forging wheel lugs consists of upper and lower dies, which is made by superior tool steel. Once the material is stocked, and forging dies are finished, the forging process can begin. Firstly, cutting the aluminum billets into required length by automatic sawing machine. The quantity of cut aluminum billets should be the same as the quantity of wheel lug nuts. Next, heating aluminum billets to a certain temperature by furnace. Note that the heating temperature should be uniform. Too low or too high temperature will all cause forging defects. Then, place the heated billets into lower die and hit by upper die. In this step, we can see a rough forged wheel nuts form, but still with flash around. Finally, remove the flash by trimming dies. 

Of course, the complete manufacturing process of wheel lug nuts is not only limited to forging, post operations including machining and surface anodization are needed. After forging, machining will be done to remove excess material according to the finished drawing. To meet the needs of a variety of colors, the aluminum forged and machined wheel lug nuts will be anodized in different colors, such as yellow, black, bule, ect.
People usually see the words "drop forged" stamped on so many tools. You may wonder what the big deal is! Why do manufacturers want you to know that a tool is drop forged?
If you have ever seen a blacksmith beating on a piece of red hot iron with a hammer, you have seen the simplest type of forging. Striking a piece of hot metal with a hammer is forging, and blacksmiths have been doing this for centuries. As blacksmiths experimented with new techniques, they learned that complex shapes could be created by hammering metal into a die. The die contains the shape of the finished product. Modern manufacturers use either a falling hammer or a powered hammer to do the hammering (rather than doing it by hand), and usually use dies on both sides of the piece. This is drop forging.
Aluminum cold forging is an impact forming process that plastically deforms a piece of raw aluminum material, under high compressive force, between a punch and a die within suitable equipment such as a machine press. Actually, aluminum cold forging forms the existing material into the desired shape; contrast this with conventional machining, in which material is removed to create the desired shape. Aluminum cold forging offers several significant advantages. The final section provides some of the key factors that should be kept in mind when considering aluminum cold forging as a manufacturing process. 

Aluminum cold forging utilizes the plasticity of aluminum alloys at room temperature to shape them. Before this processing method was applied, metals were mainly finished by cutting. But cutting materials down from the start is time consuming and produces a large amount of shavings. That is why so much interest is being shown in cold forging, because this technique makes processing times shorter and does not produce shavings.
Due to the advantages of aluminum forging, anyone working in the forging industry knows that use of aluminum forging is growing. Even with fluctuating prices, the demand of aluminum forgings is still much stronger compared to steel forgings and copper forgings.

To save costs, lots of foreign buyers are happy to make aluminum forgings in China. We all know that a reliable supplier can not only help to supply good quality products, but also save costs for you. Then, how to choose a good aluminum forging supplier in China? 
Before you place your first order to a new aluminum forging supplier in China, you need to be very careful for the choice you make, which Chinese manufacturer you should go? There are terrible stories, consequence of wrong choices made, that I heard more than once from my friends from west. As a local Chinese aluminum forging company, I would like to share some guidelines with you.
forged steel c clamps
Forging of C Clamps can be strong and durable enough, they are always produced in forged steel. Buying forged steel C Clamps in China can help our customers to achieve competitive prices in the market, which is really a wise choice. The drop forging process creates c clamps that are stronger than those manufactured by any other metalworking process. Drop forging takes advantage of the metal’s natural grain flow, shaping the grain flow to conform to the contours of each c clamp’s unique geometry. This grain flow contouring is lost when cutting through the grain by machining it and is also lost when casting parts. Forged steel c clamps can be nearly any shape, which reduces the need for extra machining. 

CFS Forge is the premier forged steel c clamps provider. Operating out of six production lines in china, one of our greatest strengths is in the diversity of solutions we offer. The types of forged steel c clamps we produce can be in different sizes, ranging from 0.5kg up to 10kgs.

Together with value added services, allowing us to stay competitive and directly supply finished product to our customers. 
Forging and Machining for Brass Valve, Pipe or Plumbing Fittings
Among all the metalworking processes, forging is the most ideal method to produce Brass Valve, Pipe or Plumbing Fittings. Several advantages are given with forging, for example, by forging, the brass material will be pressed and the grain struction will be improved, which will make the strength of Valve, Pipe or Plumbing Fittings much better. Besides, due to the large demands of Valve, Pipe or Plumbing Fittings, the order quantity is large. The production efficiency of forging is much higher than casting, which will shorten the lead time under the basis of high quality. Next, precision forging can give a close tolerance, which can reduce further machining and save cost. Lastly, the forging cost is also lower than casting in the long term. So, forging is always preferred by our customers.

However, forging is not omnipotent, it has limitation on the shape of Brass Valve, Pipe or Plumbing Fittings. And for some areas with close tolerances or threaded holes, extra machining is required. Machining is a processing process that will remove the excess brass materia of Brass Valve, Pipe or Plumbing Fittings. When there is a high requirement on surface finish (such as Ra3.2 or Ra1.6), or closer tolerance that far from general forging tolerance, or thread holes, we can only meet by machining. CFS Forge has full set of machining equipments in house. With skilled machining capacility, our customers can enjoy shorter lead time and less production cost. Of course, besides forging & machining, we can also supply various surface treatment requirements, such as shot blasting, sand blasting, electroplating, polishing, ect.
Hot forging aluminum and aluminum alloys holds many benefits for applications. The process does not impede the ability of manufacturers to manipulate and cut aluminum products easily. Therefore, forged aluminum alloys can be cut into distinctly complex or ornate shapes.

When hot forged, aluminum alloys demonstrate some mechanical qualities comparable with steel, and the strength to weight ratio of aluminum exceeds that of steel. In addition, aluminum hot forging can produce a number of surface finishes, ranging from very smooth to relatively sharp.

Aluminum hot forgings are generally cost-effective and attractive in their appearance. They allow for high design flexibility and in many cases, the exterior part of hot forged aluminum does not require extensive polishing.

For all these reasons, numerous industries make use of aluminum forgings. The process especially attracts manufacturers seeking to produce large, customized components using aluminum or its alloys.
Drop forging is a type of forging. It is used when a large quantity of certain components with sound and good quality forgings are to be produced. The die used in drop forging consists of two halves. The lower half part of die is fastened to the anvil while the upper half part is fixed to the movable ram. The heated bar or billet is kept in the lower die while the ram delivers four to five strokes (blows) on the metal. When these two die halves come together in closed alignment, the metal spreads and completely fills the die cavity.

Production costs for drop forgings are changable due to varify on many factors. Currently in China, the prices for producing drop forgings are keeping increasing. Such inceasing can be caused by several factors, such as raw material costs, labour costs, etc. Below are the factors that cause the prices of drop forgings increasing briefly.

Key Considerations for Sourcing Drop Forgings
The technique of drop forging has evolved over the ages and what began as an art form, where decorative objects were produced from precious metals, developed into a technically advanced manufacturing process, with an equally complex supply chain. 
Drop forging is now a major global industry, supplying high strength components for many of the world’s most innovative products and industries: automotive, truck & bus, defense, aerospace, and energy, which makes it imperative for buyers sourcing drop forged components to understand the process types, value stream map, technical advantages, and early supply partner involvement to effectively execute strategic procurement.

Buyers should be well-versed within above key considerations before sourcing a forging to ensure sourcing success. There must be cross-functional team awareness on the true cost and not just the short-term piece price cost to ensure long-term drop forging supply success. Drop forgings are unique and every case must be analyzed and clearly understood prior to starting the procurement process. Keep in mind these key considerations and you will be well positioned to offer your company the best supply options while driving down your drop forging true cost, which will create a win-win value and relationship across organization and supply partners.
Drop forging is one of the common ways to manufacture a metal component. But what creats this method and why drop forgings so remarkably strong and tough? There are mainly two key aspects explaining why drop forging creates stronger products than other metal working processes and is an ideal manufacturing process for many critical metal components: predictable grain structure and uniformity.  

The traditional process of drop forging involves heating a billet and placing it into a die, where it then is put under extreme pressure by a “hammer” and forced into the die's shape. During this process, the grain flow of the metal is actually altered, conforming to the shape of the part. This process makes the metal component stronger, tougher and much more reliable. The importance of grain structure cannot be underestimated. The process of bar stock and plate machining, for example, creates unidirectional grain flow. This means that any changes to the contour will ultimately cut flow lines, exposing the grain ends and making the metal more vulnerable to fatigue and corrosion.

The grain structure and flow created during the drop forging process is directional and has been placed in a way as to increase the strength and toughness of the part, thus creating overall directional strength. Since no grain ends are exposed, a drop forged metal component is less susceptible to wear and tear.
applications of aluminum forgings
The demand of aluminum forging is getting larger than before. Here are some main advantages of aluminum forgings:

  • Low density, only 34% of steel forgings and 30% of copper forgings. Aluminum alloys are ideal lightweight materials.
  • High strength, high stiffness, high elastic modulus and high fatigue strength, it is suitable for the key stressed parts with high requirement of lightening. Its comprehensive performance is much higher than that of other materials.
  • The internal structure is compact, uniform and free of defects, and its reliability is much higher than that of aluminum alloy castings and other metal castings.
  • Aluminum alloy has good plasticity, which can be processed into high-precision forging pieces with complex shapes. The machining allowance is small, only about 20% of the machining allowance of aluminum alloy tensile thick plate, which greatly saves time and cost.
  • Aluminum forgings have good corrosion resistance, thermal conductivity and non - magnetic properties, which cannot be compared with steel forgings.
  • The surface is bright and clean, beautiful. Besides, the surface treatment performance is good, beautiful and durable.
  • It can be seen that aluminum forgings have a series of excellent features, providing good conditions for aluminum forgings to replace steel, copper, magnesium, wood and plastics.
forging of aluminum alloys
Forging process is the common metal working process in production. It mainly takes advantage of the plasticity of materials and causes plastic deformation of materials with the help of external forces, so as to obtain required shapes, sizes and certain performances. As far as the forging process itself is concerned, the advantage is that the inside of the forging is compact, the structure is relatively uniform, and there are no pores in the interior. The drawback is that larger deformation forces are required. According to the placement of tools and molds, forging can be divided into open die forging, 
closed die forging and roll forging. Open die forging is formed by a fixed flat anvil, the forging die of roll forging is mobile, and the forging die of closed die forging is fixed. According to the forging temperature, forging can be divided into hot forging, cold forging and warm forging. Aluminum and aluminum alloy are the most widely used nonferrous metals, with the yield second only to that of steel. Some key processes in aluminum alloy forging are introduced below.

Aluminum alloy can be used in the manufacturing of mechanical parts or components which bear large loads and become widely used non-ferrous metal materials in the industry. Due to its high specific strength and light weight, aluminum alloy becomes the main structural material of aerospace forgings. As a common metal material in daily forging production, the application of aluminum alloy is far more than that. More applications and improvements of aluminum forgings need to be found.
In commercial closed-die forging, the workpiece is usually moved though a series of cavities in a die to get from an ingot to the final form. The first impression is used to distribute the metal into the rough shape in accordance to the needs of later cavities; this impression is called a edging, fullering, or bending impression. The following cavities are called blocking cavities in which the workpiece is working into a shape that more and more resembles the final product. These stages usually impart the workpiece will generous bends and large fillets. The final shape is forged in a final or finisher impression cavity. If there is only a short run of parts to be done it may be more economical for the die to lack a final impression cavity and rather machine the final features.

drop forged chair components
Question: “We currently have a Marine Deck chair manufactured for us, but with alloy castings. Need to change the castings into drop forged components so we can anodize. Can your forging company help me?” Mitchell said.

Mitchell is the deck chair seller in New Zealand, who ever had his chair fittings casted in aluminum alloy. But now due to the fact that both the surface finish and strength of casted chair fittings are not good, so he wants to convert these aluminum chair fittings into drop forging process.

He did not have the technical drawings, but sent us the actual samples, which were originally casted. Once the samples were received, we found that there are totally six components, which are all not large. According to the shapes of these samples, our engineer judged that we had the ability to change these castings into drop forged components. But due to the differences between casting and forging, some post machining operations would be added after forging. In terms of casting, the effect of anodization treatment is not good, so this kind of surface finish is only suitable for aluminum forgings, whose surface will look shining and smooth.
Forging is the metal processing process that puts pressure on metal billets, which will occur plastic deformation to achieve a certain mechanical properties and desired shape by the use of forging press machinery. Brass is the most common material in copper forging.

Brass Forging is usually operated under high temperature, we call this hot forging. Brass can have good plasticity both under room temperature and high temperature, but it has better mobility, which will reduce metal deformation resistance. This will not only increase the forgability of brass, but also make brass easy to flow and form.

Although brass has good plasticity at room temperature and high temperature, there is a medium temperature brittleness zone, so the forging temperature range is narrow. Temperature control is of vital importance. Taking HPb59-1 for example, the proper forging temperature should be at 680-750℃。
copper forging china
copper forging process, a metal part is heated and formed into a predetermined shape between a set of dies. The process involves heating a metal slug and then pressing it into shape within a die cavity. Not only is the metal shaped, but the forging process also improves the mechanical and physical properties of the part. Forging today is performed on high-speed automatic equipment.

Therefore these purpose necessary parameters which are steered precisely such as the temperature of the tool and the rough stamping, the velocity of transforming and the shaping energy are basic requirements for a high quality deformation.
how to select forging materialsThe material that is selected for forging process must be one that can achieve the required physical and mechanical properties. Where alloys from several groups meet performance requirements, the most economical alloy, in terms of material and processing costs, should be chosen. See below summary on making a preliminary selection of forging materials:

Carbon, microalloyed and alloy steels are low to moderate in cost. The main cost drivers are processing and machining. The alloys are readily hot forged and some shapes are cold forgeable in selected alloys. When precision or closed die forgings are anticipated, the designer should be aware that eventual purchased quantities of forgings should be large enough to justify the typical added tooling preparation charge. There are times when the added tooling costs are well justified to eliminate a difficult to machine shape regardless of purchase quantities.
copper forging advantagesCopper forging offers a number of advantages over copper products made by other processes (such as copper casting). Dimensional precision is greater than by casting, working the alloys develops improved strength, and overall cost is modest. Zero draft forgings are possible, though not always practical. However, minimum draft forgings are being produced. Minimum draft capability is independent of alloy composition; alloys that can be forged by conventional means can be forged to minimum draft angles approaching 1°.

Copper forgings are common and provide near-net shape parts with minimal waste. Copper forgings mainly include brass forging whose major alloying element is zinc, and bronze forging whose major alloying element is other than zinc, such as silicon bronze and aluminum bronze. Pour copper contains very high copper content, typically 98% or more, such as beryllium copper. Copper based alloys are designated by a six-character alpha-numeric system. The first character is C, indicating the copper base. The next five are numeric characters. The first numeric indicates the major group, and the remaining four designate the alloys within the group.

Drop, press, rolling, hot, cold, warm; there is a wide variety of processes that forging materials can take to 
manufacture parts for today’s consumers and enterprises. However, there is one manufacturing process that stands out among them all for value, time, and dependability: drop forging.

Similar to press, and ring rolled forgings, with closed-die drop forgings the billet is heated to a point of most malleability without changing to liquid state; it remains in a solid state the entire forging process. Casting on the other hand takes a material and heats it completely to the melting point and pours this liquid metal into a formed cast (see casting vs forging). This is easier to produce more geometrically complex shapes however, the durability and overall quality is lesser, takes more resources, and is not as cost effective with material scrap. Drop forgings minimize wasted material and are cost-effective, quick, and retain their durability under considerable stresses. This makes drop forging best for industrial metal components.
Drop forging is manufacturing process where metal is pressed under great pressure into high strength parts known as drop forgings. The process is normally (but not always) performed hot by preheating the metal to a desired temperature before it is worked. It is important to note that the drop forging process is entirely different from the casting process, as metal used to make forged parts is never melted and poured (as in the casting process).

The drop forging process can create parts that are stronger than those manufactured by any other metalworking process. This is why forgings are almost always used where reliability and human safety are critical. But you'll rarely see drop forgings, as they are normally component parts contained inside assembled items such a airplanes, automobiles, tractors, ships, oil drilling equipment, engines, missiles and all kinds of capital equipment - to name a few.

Drop forging is a superior to casting or machining bar stock since the metal’s natural grain flow is made to conform to the shape of the product. Castings have an isotropic grain structure and, for a given part, may be as strong in compression loads, but forgings are superior in tensile and shear loads due to the utilization of the grain flow.

Fly Forge typically uses specialty bar stock as our incoming raw material. As these metal bars are heated and forged, the grain structure within the material is forced to flow along the centerline of the bar.  When a forging is produced from the bar, this inherent grain flow follows the contour of the forged shape. Any machined part, whether produced from bars or plate, will by definition cut through part of the grain flow. Castings essentially have no grain direction. This is one of the primary reasons forging produces a superior part.

The structural reliability of drop forgings allows designers to trust the material to adhere to the safety factors of the design.  It also can provide more uniform response to heat treatment and machining operations.

 is a key part of the automotive generator and also the main component forming a rotating magnetic field. Shown in below picture, the shape is very complex with six high and sharp claws. Its shape and electromagnetic properties directly affect wave form of the induced EMF and power generation capacity of the AC alternator, so size accuracy is highly required.

Although there are lots of suppliers for forging claw pole, there still exsit difficulties to make this part, such as the process is multi-step and long, lifespan of the mould is short, cost is high, and the quality is hard guaranteed.

The main reasons are that the top of claw-pole is hardly completely filled, loading of the forging is heavy (more than 1000 tons), consumption of the burrs is high and the flow line of metal is complex. How to form the top of claw-pole with lighter loading, reduce the material consumption and make the flow line more conductive, all the above issues are the key difficulties in producing claw pole.

Aluminum alloy, for its advantages of small density, good strength, as well as good workability, has been widely used in various fields. In order to achieve energy saving and weight loss, the United States, Japan and Western Europe and other developed countries are increasing the research and development of aluminum forging technology.

The aluminum alloy control arm is the key component of automotive steering system. In this paper, a precision forging automation production line of aluminium forged control arm is introduced in detail from the view of technology and equipment.
T6 heat treatment for aluminum forgings
Aluminum forgings are heat treated for the same purpose as steel forgings: to relieve stresses, improve mechanical properties or facilitate machining. The processes generally produce nearly uniform properties throughout the forging, and are not used for localized effects such as surface hardening.

For most of the forged aluminum alloys: 60616063 and 7075, most commonly used heat treatment method is T6 heat treatment. T6 heat treatment of aluminum forgings offers increase in hardness and other mechanical properties, which is often required for many applications. 

It takes a certain amount of time and energy to qualify a potential forging supplier. Getting the best value from any forging requires a cooperative effort on the part of the customer and the forging supplier. Good planning ahead of time will pay dividends for both you (the customer) and the supplier.

Assuming you have a drop forging part ready for sampling or production, the first place to start with any new forging company is to request pricing for the part. The purpose of requesting a quotation for a forging is to determine capability, experience and the lowest possible forging price of a potential vendor supplier. It is always advisable to have more than one forging company participate in the quoting process.
Steel and aluminum are the two most popular closed die forging materials used in hot forging. Each material has a defined and distinct set of characteristics that make it the right – or the wrong – material for the application. Below are the main differences of steel forging and aluminum forging, that can help you to consider your design with a ideal forging material.

Cost and price are always an essential factor to consider when making any product by hot forging. The price of steel bars and aluminum bars is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum. The cost of raw materials has a direct impact on the price of the finished forged products. 

6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. It has generally good mechanical properties and is forgeable and heat treatable.

Like 6061 aluminum, 6063 is one of the most common alloy used for aluminium forging. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications. Applications requiring higher strength typically use 6061 or 6082 instead.

6061 vs 6063 aluminum forgings
 and 6063 aluminum alloys are the most common alloys for forging. Although they possess many of the same qualities, they each offer their own distinct properties that mean manufacturers need to do their research when deciding between them.

The second most popular aluminum for forging, 6061 is precipitation-hardened and uses magnesium and silicon as its major alloying elements. It was first developed in 1935 as part of the early advances in the aircraft industry. It offers good weldability and machinability, good joining characteristics, accepts applied coatings well, and is highly corrosion resistance while having a high strength to weight ratio. In contrast, 6063 is the most popular aluminum used for forging. It also uses magnesium and silicon as its alloying elements. Its unique properties allow it to be formed into complex shapes with very smooth surfaces, making it fit for anodizing. Its major drawback compared to 6061 is that it does not have the same level of strength.

Aluminium alloy 6061 is one of the most extensively used forging alloy of the 6000 series aluminium alloys. 
6061-T6 aluminum properties include its structural strength and toughness. It is also offers good finishing characteristics and responds well to anodizing, including clear, clear and color dye, and hardcoat. 6061 aluminum alloy is also easily welded and joined. However, in its –T6 condition the welds may lose some strength, which can be restored by re-heat-treating and artificially aging.

CFS Forge is the expert in 6061 aluminum closed die forging. Producing top-quality 6061 aluminum forged parts, CFS' forging capabilities are not limited by size, shape or quantities. Any inquiry on 6061 aluminum forgings, pls contact us.

Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of forgings.

Fly Forge is one of the few forging companies that can provide vibratory polishing service of forgings for our customers in China. Besides vibratory polishing, we can also other surface treatment services of forgings include shot blasting, powder coating, electropolishing, color painting, ect. All our forgings serves the agricultural, aerospace, automotive, medical, and construction equipment industries.
With a number of beneficial properties, aluminum forging is an easy choice for manufacturing aircraft. Wood was originally used to build aircraft, but it is prone to rot and can splinter without proper maintenance. Likewise, steel forging is stronger than aluminum forging, but weighs significantly more. Steel forging is only used in aircraft when extremely high strength is needed, such as landing gears.

Fly Drop Forge is a leading manufacturer of aluminum forgings in closed die forging process for aerospace application. End use applications include landing gear, engines, structural components, brakes and rotors components. Fly Forge has the experience and expertise in aluminum forgings that ensures the structural durability and high strength-to-weight ratio capabilities needed in a aluminum forged product for aerospace applications. Contact us today to talk about your aluminum forgings needs and how we can get your project done quickly and to your specifications.
Closed die forging is not limited to steel components, it can be used to produce aluminum components as well, just different heating methods. Before forging of aluminum alloys, blanks are cut from round bars, then these aluminum bars are preheated to temperatures in the range of 400° - 500°C, according to the alloy used. 

At Fly Forge, our closed die forging process can produce aluminum components in all shapes and sizes required to conform to your specifications. We supply our superb custom-made aluminum forgings to meet our customers' needs and even exceed their expectations.

Simply introduction of forging process: Selecting equal specification bars in stock, and cutting them into required length by sawing machine. Heat them to a certain temperature by heating furnace 
(medium frequency furnace). Next, place them under forging dies and press in few seconds for desired shape. Finally, remove the flash and shot blasting to final dimensions. In most cases, machining will be done after forging.

Advantages of forged torque rod bush:
  • Greater strength to weight ratio
  • Better fatigue resistance
  • Continuous grain flow
  • Reliable and consistent quality.
anodizing for aluminum forgings
Anodization or Anodizing treatment is the common surface finishing/coating method used for aluminum components, including aluminum castings, aluminum forgings, and even machined aluminum parts. Aluminum forged part is "anodized" for corrosion resistance, improved appearance, hardness & wear resistance, and for a number of specialized reasons like better glue-ability (adhesive bonding) for structural use, improved paint adhesion, and enhanced capacitance in electronic applications.Aluminum forgings are better than castings for anodizing due to a denser, more homogeneous microstructure. CFS Forge is the leading manufacturer for finished aluminum forgings, including closed die forging, cnc machining, surface finishing, heat treatment. So we can also deal with aluminum forgings that require further anodization. 

So, in order to reduce the weight of the product and protect the environment, many metal components are converted into aluminum forging with hard anodizing treatment, which were originally produced in steel forgings with hard chrome plating.

The claw pole is the key part of the motor generator. the material quality and forging forming quality of the claw pole are the key factors that affect the output power of the generator. 
Forging has the features of high material utilization, dense inner structure and excellent product performance. So forging is the best technology solution for claw pole to replace castings with environmental protection and high quality. 

Our forging service is provided not limited to claw poles, but for all custom components for the automotive industry, building and construction, engineering, mining, power generation and distribution, communications, government, defence, railways, ports, harbours and marine, the road transport industry, oil and gas/petrochemical, chemical and process plant, aerospace, agriculture, fastener distribution /merchants, tool and engineering / merchant, etc.
As one of the main metalworking process, China forging industry has achieved remarkable progress in the past 40 years. Currently, the annual output of Chinese forgings have reached 11 million tons, occupying 39% of global forging production. There are totally 420,000 employees working for forging companies in China, making China the largest global producer of forgings with the most complete forging capacity.

Like Chinese others' industries, the lack of forging technical engineers and workers is getting more serious caused by the rapid econimic expansion in China. To relieve this problem, so some Chinese forging companies like Fly Forge have gradually invested some automatic production lines to ensure normal production.In general, China’s forging industry is progressing in the direction of providing complete solutions that integrate materials technology, forming technology and post-processing.

There is an increasing use of light metals in forging process, such as aluminum alloy. Aluminum forging has been proved forging type in a wide of applications, especially for automotive industry. 
Compared with aluminum casting, aluminum forging is more reliable for the designer to consider when there is a requirement on strength. The design of aluminum forging can often provide the new part desired light weight and high strength at low cost. These characteristics make companies gradually replace their original parts with aluminum forging. 

So, why aluminum forging? What are the advantages?
When forged and heat treated, aluminum forgings exhibit some mechanical properties comparable with seel forgings. The strength to weight ratio is therefore far superior. For example, the 2014-T6 aluminum forging has a typical UTS of 485MPa, exceeding that of many grades of steel forgings, and all commonly used aluminum castings. Unlike casting, forging is always porosity free (forging vs casting) thus allowing relatively straight forward heat treatment processes that significantly improve selected mechanical characteristics. The lower cost 6061 aluminum forging attains typical values of 310MPa, which is also superior to, for example, A356 (or 601 type) aluminum casting whether that alloy is semi-solid cast, squeeze cast or gravity cast. Further fabrication by welding is also available with 6061 aluminium, allowing it available for many other applications.
drop forging china
Drop Forging is used to produce steel forgings and aluminum forgings, by pressing heated metals – under high pressure – into desired final shapes under the workforce of forging dies, this process is also called closed die forging. They can be designed to produce simple to complicated forgings with high dimensional accuracy. Our drop forging company manufactures parts with high strength, good toughness and wear resistance with smooth surfaces. Our company is a Tier 1 and Tier 2 supplier for the following industries: Automotive, Agricultural, Commercial Vehicle, Heavy Equipment, Oilfield, Off-Highway and Recreational Vehicles.

The most attractive factor that guides companies to source drop forging services from China is that, in China, they can buy high quality drop forgings as good as their local suppliers, but can save much costs and win more profit. So more and more overseas companies turn to China drop forging company like Fly Forge for their projects.

Drop Forging could be used for the manufacturing of all types of lifting components. These components include: Eye bolts, eye nuts, Safety Swivel Hoist Rings,
 Turnbuckles, C-Clamps, D-Rings and Clips, Plain Clamps, ect. All these lifting components require drop forged because they need to bear high weights when working, and the strength much be high enough. Drop forging process could increase the strength during the forging process, while casting could not reach such effect.

Fly Forge is the drop forging specialist in producing all types of lifting components in competitive prices and good quality. All these products are mainly exported to countries like USA, UK, Australia, Canada, ect. Below is the introduction of main drop forged lifting components we have made for our customers:

Closed die forging is a process by which a billet of simple cross section is plastically deformed by applying compressive forces through dies or tools to obtain a more complex shape. In closed die forging, two or more dies are moved toward other to form a metal billet that is heated to the appropriate forging temperature. This process is capable of producing components of high quality at moderate cost. It offers a high strength-toweight ratio, toughness, and resistance to impact and fatigue. This forging technique allows us to produce lots of metal components with critical safety consideration. 

Closed die forgings could be served for components in automobile/automotive industry and in aircraft, railroad, and mining equipment. And, marine industry is also one of the main field that closed die forging involves in. At Fly Forge, we are considered as a world class supplier of marine forgings in China, and we pride ourselves in supplying quality products with lowest costs. Pls contact us while you have such needs.
drop forged compactor caps
Padfoot rollers are designed to compact the ground before placing concrete. Padfoot rollers use the weight of the vehicle to compress the surface being rolled. Rollers are also used in landfill compaction. Such compactors typically have padfoot or "sheep's-foot" drums, and do not achieve a smooth surface. The pads aid in compression, due to the smaller area contacting the ground.

Fly Forge supply drop forging service for compator caps which will be welded on padfoot roller. After delivering compactor caps to our customer, they will be welded on padfoot roller. Such compactor caps are easy worn out, but could be replaced by new ones, and then welded on padfoot roller again. If you require such products, pls feel free to contact us. We are able to customize any dimensions you like.

Material is forged steel. Such small part needs to be closed die forged. Close Die Forging is an inexpensive and efficient way to manufacture forged steel parts and it can also be made in many different steel alloys, such as carbon steel, alloy steel ,stainless steel ,ect., it depends on the application. At Fly Forge, we can take any design and metal and turn it into a finished component.
In terms of temperature, there are different types of forging: hot forging, warm forging and cold forging. Hot forging is the most popular forging process among these forging types. All the forging technique used in Fly Forge is hot forging, so this article we will introduce hot forging in detail.

Hot forging, also called drop forging, is a process to produce a wide variety of most metal parts. Hot forging process is developed since the last century, but with the development of equipment, lubricants, and forging ability, modern hot forging process is able to make more complex shapes with more materials since that time. The basic procedure for hot forging is relatively simple. Metal bar or billet is first heated into the hot working temperature range to improve ductility. Then the material is squeezed or hammered in a series of tool steel dies to deform the billet into the finished shape. Flash casused by excess material after forging is exsited, so the final step is to remove the flash to yield the finished forged part. Hot forging is a near net shape process, but some forgings may require some subsequent machining, in particular for surfaces that may affect the final assembly of a product.

We all know that machining is a precise operation based on casting, forging or billets directly. Closed die forging is a recision processing process for net shape or near net shape 
products. And there are lots of advantages like tight tolerances, good surface finish, few defects, ect. All these advantages attract our customers to prefer closed die forging more than investment casting (forging vs casting). Although closed die forging dies are much more expensire than that of investment castings, in the long term, closed die forging is more cost-effective, as a pair of forging dies can produce approximately 50,000pcs forgings. That is to say, closed die forging is the most ideal process for making large quantity runs.  

But it does mean closed die forging is prefect. In most conditions, closed die forging can elimate some machining job that is required after casting. In closed die forging, the heated billet is pressed between forging dies into desired shapes. So some dimensions can not be realised by forging, such as thread holes or other small holes. We have to leave some machining allowance when forging. 
Open die forging is another drop forging process that metal is getting deformed for desire shapes without any limitation  between the top and bottom anvils in all directions utilizing power or pressure. So it is also named as free forging.

Main feature of open die forging is that the production equipment is relatively simple, so the cost is low. Compared with the casting blank, open die forging eliminates the defects such as shrinkage, gas holes, porosity, ect. So products after open die forging have higher mechanical properties. As open die forging shape is simple and the operation is  flexible, therefore, it always act as important parts in heavy machinery equipments.   
With the most commonly used method, the billet is heated and placed into a special kind of tooling called a 'die'. The heated metal is put under extreme pressure and forced into the shape of the 'die'. Unlike the 'cut' that it once came from, the grain flow is directional and has been orientated in a way to increase strength/toughness (i.e increases steel ductility and impact resistance). Also, as no grain ends are exposed, a forged item is less susceptible to fatigue and stress. 

In short, the forging process adds an approx. 30% increase in strength/toughness over original billet it was made from. Compared to casting (forging vs casting), the initial tooling costs of forging are much more expensive, thus it is required to manufacture in high quantities to 'break-even' on the initial expense. But due to the advantages of forging, this is a very cost-efficient method for large volume production. 
What is grain structure? Grain flow is a directional orientation of metal grains and any inclusions that have been deformed by forging. Individual grains are elongated in the direction of the metal flow or plastic deformation. More importantly, nonmetallic inclusions, particles and other imperfections inherited from the casting process (forging vs casting) are elongated in the direction of grain flow. It should be noted that grain flow occurs to some degree in all metal-forming processes, not just forging. As a professional forging manufacturer, this article we would like to discuss how forging affects grain structure.

Grain flow is one of the major benefits by the use of forgings. Unfortunately, there are misconceptions on the topic, which include the underlying causes of grain flow, the benefits that can be accrued from grain flow and how to achieve an optimum grain flow. In the best case, grain flow results in more application of forgings, especially for some critical applications when safety and strength is considered.
Forging is a manufacturing process by which metal is pressed under great pressure into high strength desired parts. The process is normally (but not always) performed hot by preheating the metal to a desired temperature before it is worked. It’s important to note that the forging process is entirely different from the casting  process (forging vs casting), as metal used to make forged parts is never melted and poured as operated in the casting process. Forging refines the grain structure and improves the physical properties of the metal, so that the grain flow can be oriented in the direction of principal stresses encountered in actual use. Physical properties such as strength, ductility, and toughness are much better in a forging than in the base metal.

Forging can refine the grain structure of products. Forging is superior to casting or machining bar stock because the metal’s natural grain flow is made to conform to the shape of the product. Castings have an isotropic grain structure and, for a given part, may be as strong in compression loads, but standard and custom forgings are superior in tensile and shear loads due to the utilization of the grain flow. The structural reliability of forgings allows designers to trust the material to adhere to the safety factors of the design. It also can provide more uniform response to heat treatment and machining operations. 
It has been a long history since closed die forging is worked as the metal forming process. Closed die forging is now a major global manufacturing industry and supplys metal components to many industries: automotive, defense, aerespace, agriculture, oilfied and others. Since closed die forging is a manufacturing methods for metal components, it is imperative for buyers to understand some related information about it. 

Buyes should be well-versed within above guidelines before making a forging to ensure sourcing success. Closed die forgings are unique and every case must be analyzed and clearly understood prior to starting the procurement process. Keep in mind these guidelines and you will be well positioned to offer your company the best supply options while driving down your forging true cost, which will create a win-win value and relationship across closed die forging manufacturer and buyer.
precision forging
It has been a popular trend that people source precision forgings from China. This creats lots of Chinese precision forging companies and also promotes the exporting in field of forging industry. 

We, Ningbo Fly Drop Forge Co.,Ltd is the leader in manufacturing precision forgings for industries like aerospace, Agriculture, Automotive, Rail, Military, Mining, Oil and Gas, Power Generation, Nuclear, Firearms, ect. Here "Precision Forging China" means precision forging components made in China. Today we would like  to talk about something all related to "Precision Forging China".

Recently, one of our clients from USA sent lots of samples to our drop forging company. These components was originally made by casting with steel. But the user found that the serving life of 
these casting products are short. To add the strength and longer the working life, they would like to use our closed die forging process instead.

From above case, you can see we can supply redesign service to our customers for closed die forgings. Our professional technical team will help you to redesign the parts according to the usage and our forging technology. Due to our specialty on forging, we can supply high quality forgings to customers. Thus they can sell or use well in their market, and we can win more orders for closed die forgings.
When choosing a metalworking process for your parts, you should be always confused at this problem. When designers or users begin to evaluate the benefits and performance of forgings with castings, they should realize that forging can offer competitive price-wise while delivering top-quality components. Additionally, with the develop of forging technology, modern forging facilities are able to produce forgings for applications with more complex shapes.

Pls note forging can not 100% replace of steel castings at present.  In some situations, casting is the best solution. If you insist on our forging technology, then you might have to change the design slightly so that your part can be shaped in our forging equipments. But if the design can not be changed, then you can not convert your casting part into forging. When working closely with your forging supplier, you should state your project in detail at the beginning of your project which outlines all your related issues. By the end of your discussions, your forging partner will be able to provide a solution that best solve the problems.
Price is the major factor that most American and Eourpean compaines source precision forgings in China. Especially for those precision forging distributors, they has a district control on the cost of finished precision forging parts. As a leading precision forging company in China, we would like to talk about how to source precision forgings in China. This article will guide our customers to source more prefessional precision forging manufacturers, and avoid any loss during the whole purchasing process.

Precision Forging is a process where metal is preheated and pressed into desires shapes with forging equipments in different tons. Precision Casting is the metal forming process by puring metal liquid into shell mold, cut the products from the tree assembling after cooling, and remove excess material for final product by polishing.

After forging, the inner grain structure is refined. So precision forging process creates products with better strength than those manufactured by any other metalworking process. Forging takes advantage of the metal’s natural grain flow, shaping the grain flow to conform to the contours of each part’s unique geometry. This grain flow contouring is called flash, and it will be removed by trimming dies. So normally, precision forged parts will require at least two pairs of moulds. Precision Forging can provide net shape products, which reduces further machining job and thus, machining cost can be saved. 

In order to achieve high surface hardness and surface roughness, improve fatigue strength, and meet working performance of drop forgings, Mechanical processing will be operated after carburizing treatment. The mechanical processing after carburizing treatment is generally as follows:

1) Machining
The surface carbon content after carburizing is high, and after heat treatment, the surface of drop forged blanks will exsit a large amount of residual austenite, easy to form grinding cracks, such as burns and crack, in the process of grinding. Besides, grinding crack can also produce if there is thick carbide, carbide network or carbide film. So in the process of Mechanical Processing, we should refer to the technical requirements of carburizing forgings, choose the correct process parameters according to the specific characteristics. This will help improve the quality of the drop forgings, and can guide the actual machining.
Carburzing Treatment is a common heat treatment methods, it is a chemical process that carbon atoms entering the surface of drop forged products by heating drop forgings into carburzing medium and heat preservation, thus to increase the carbon content of surface layer, and form a certain carbon concentration gradient.

Materials of drop forgings that require carbuzing treatment are commonly selected as low carbon steel or low alloy steel (carbon content less than 0.25%). To maximum the working performance of carburizing treatment, drop forgings need to be quenched after carburizing treatment. Normally, the depth of carburizing treatment is 0.8-2mm. After carburizing, the surface hardness of drop forgings can reach HRC58-63, and the inner hardness can be HRC30~42. In addition, After carburizing, the surface of drop forgings will compress the internal stress, which will be beneficial to improve the fatigue strength of products. Therefore, carburizing is widely used in drop forging to impreve the strength, impact toughness and wear resistance, thus to longer the working life of forgings.
Heavy Duty Grab Hooks are used to be welded on to equipment buckets, trailers, or other surface that needs a fixed hook. Such weldable grab hooks are mainly designed in different dimensions for different weight bearing requirement. Larger hooks can bear more, just see what the application will be.

According to the application of weldable grab hooks, they need to be forged for safety consideration. It may be easy to produce inside defects by casting, which is a great risk when working. So, there is no doubt that grab hooks should be made in forging. 
For its special usage, there is  a high requirement on the strength of silp yokes and no defects are allowed. So slip yoke is usually designed by drop forging process, other than investment casting. The first step to start silp yoke manufacturing is its forging dies, like other drop forged products, normally the tooling cost of slip yoke is much more expensive than cast ones. But it is affordable in our company and we will be in charge of the follow-up maintenance work, it is just one-time cost. As an OEM drop forging company, we can customize all kinds of forged slip yokes according to your specifications.

Forging is not the stop, precision machining is another manufacturing point for slip yokes. Our advanced machining equipments can offer you most precision machined slip yokes. So we are experts in manufacturing and exporting slip yokes to overseas customers, just pls feel free to contact us if you are interested. 
forged steel valve componentAccording to above information, we can see both forging and casting methods have its own advantages. In comparison to castings, the structure of forgings ensures wall thickness and dimensional tolerances are uniform. High impact closed die press forces and a segregation free billet guarantees superior strength, uniformity, integrity and density. Casting issues include inter granular corrosion, stress weakness, fatigue, cracks, porosity, sand pockets, weld repairs, scars, etc. 

Another benefit of forgings is the directional flow lines structure. Due to quality concerns brought about by low cost country valve manufacturing we now often see customers first specify a forging rather than a casting, then specify it must be a European forging and an approved brand, yet they then still ask for 100% MPI and UT on common A105 valves increasing the cost exponentially. Using good quality forging can reduce the need for NDT. Of course UT and MPI is a good idea to provide reassurance of the quality, especially for castings in larger sizes and higher classes.
The past few years have seen a shift towards the use of forged steel, in particular for valves used in critical and severe service applications, such as oil industry, chemical industry, power industry, energe industry, ect. All forging processes start with a solid piece of metal or ingot that is forged into shape with hammers or presses. 

Issued with API certification, CFS Forge is reputed manufacturers and exporters of forged steel blanks for high pressure valves products (gate valve, globe valve, check valve, ball valve, etc) in Ningbo, China. We are manufacturing forged steel valve components from high grade raw materials, such as A105, SS304, SS316, ect. We are manufacturing high quality forged steel valve components in different size, shapes, design and also manufacturing as per customer's design. And all valves are well tested using latest valves technologies. We export over forged steel valves products to countries all over the world.
As a global supplier for forged steel components,our customers have long benefited from the high performance value of forged rubber track metal cores.We are alway striving for excellece in delivering innovation,value and quality.Below is the a complete manufacturing process showing how our forged rubber track metal core is made:

Step 1-Like other drop forged products,rubber track metal core is also produced by closed die forging process.So developping forging dies is the first step for manufacturing.Normally afte designing the forging dies according to the dimensions of products,it will be precision machined by CNC,which consists of upper and lower dies.
Rubber track is a conveying system widely used in construction machinery equipments(such as excavator,CTL/MTL and drill machine) and agricultural machinery(combine harvester,small dumper/carrier,tractor).The Metal core attaches itself to the sprocket and prevents the rubber track from slipping off the wheel.And the metal core is firmly bonded to the rubber by a special adhesive treatment.Below is a picture showing the usage of metal cores for your better understanding:

Due to the advantages of drop forging,such rubber track metal core will be drop forged to achieve high strength,and then heat treated to meet enough hardness,which will reduce vibration when rubber track works.Main material used for forged rubber track metal core is 1045 seel and 40Cr,we can also make metal cores in other material specification according to our customers' requirements.
Combine harvester is one of the main agricultural machinery equipments that used for harvesting grain crops, such as oats, rye, wheat, ect. Knife guard/finger is designed for increasing cutting capacity and harvesting speed. Our combine harvester knife finger/ guard are assembled to John Deere, New Holland, Claas, Ford and so on. 

For its special working condition, wear resistance is the most important factor of forged harvester knife guards. So materials with good wear-reisistance like ASTM 1045 steel or AISI4140 are applied for such products. In addition, we could also improve the wear-resistance of combine harvester kinfe guard/finger by add the hardness after heat treatment. Normally hardness of such products wil be controlled between 50-60HRC. But it does mean the higher the hardness, the better working performance the knife guard/finger will be. Too high hardness will cause products in fragile and easy broken status when woking.
In the past 15 years,due to our continuous hard working and improvement of our drop forging process, we are now supplying our customers custom forgings in below two forging methods:

1) Closed die forging: Closed die forging is the most conventional custom forging process for metal parts. It is more suitable for parts with simple shape, less budget, wide tolerance requirement.
2)Precision forging: Precision forging is an improved forging solution for small parts after closed die forging process. Compared with traditional forging process,precision forging can forge parts with more complex shapes, also it is flashless, which can save materials. But in total, the cost of precision forging is higher for its high tooling cost and operation cost.
Precision forging is worked in a close to final shape or close-tolerance forging way.It is a refinement forging techniques compare to traditional closed die forging technology.When you need a product with near net shape or net shape,precision forging is the right choice to source,such forging technic will refine the product to little or no machining.

As the precision forging manufacturer and supplier in China,we offer OEM service and exporting service for customers from USA,UK,Australia,Canada,ect.Such precision forgings are mainly involved in automotive components,agricultural machinery parts,railway components,mining machinery parts.In addition to forging,we can also provide other services like machining,heat treatment,surface treatment,custom package,ect.
forged bucket teethForged bucket teeth is the manufacturing process that putting pressure on the heated steel billet between the forging dies in high temperature,so that the material will full fill the forging dies,thus to achieve desired shape.In the forging process,the billet will be plastic deformed to obtain certain mechanical properties.Bucket teeth after forging processing can improve its organizational structure and guarantee a good mechanical performance,more wear-resisting, long service life.However,cast bucket teeth are made in the condition of high temperature molten metal and then injected in the casting molds,final cast bucket teeth are thus formed after cooling. By comparison,cast bucket teeth is more easy to products defects like air holes.And both the mechanical properties and wear resistant will be worse than that of forged bucket teeth,thus to affect the serving life of products.So we always suggest forging process for excavator bucket teeth.

Currently,as the top manufacturer and exporter of forged bucket teeth in China,we are now exporting such forged replacements for both large brand excavator manufacturers and bucket teeth distributors all over the world.To improve the properties of forged bucket teeth,we always suggest our customer to select good wear resistance forging material like 42CrMo.And heat treatment will also help to improve the hardness of products.
how steel forging compare to steel casting
Today steel forging and steel casting have been the two main production processes for steel parts.Compare to steel casting,there are a lot of advantages to use steel forging as the metal forming process.

When pressing the heated steel billet between forging dies, steel will fill the die cavity and the redundant steel will be around the shape of product, which is called flash. So the waste of whole forging process is the flash. That is why steel forging is a net or near net shape process compare to steel casting. Also, although the cost of forging dies are higher than that of casting molds, but the unit cost of steel forging is much lower than steel casting. So in terms of cost, when the quantity is large, steel forging is more cost-effective.
custom steel forgingForging is a different metal forming process compared to casting(refer to differences between forging and casting).Forging is the manufacturing process  that heated billet is pressed under great pressure to achieve desired shape.After forging,the grain structure will be refined and the mechanical properties(strength,ductility and toughness) will be improved.So that is why hot forging process is always used for custom metal parts.

In this process,forged steel is the most applicated material for its special properties.Such products are all made from our clients' drawing or sample,so we call this custom steel forging.Due to different material grades and product structures,prices of custom steel forging will be different.
When you finish the design for a metal part,you can choose both casting and forging for it(see differences between forging and casting).But if you would like to customize it in a large quantity,low cost,close tolerance,high strength and short lead time,closed die forging technology is the best choice for you.

Closed die forging can be made in different metals,such as forged steel,aluminum,brass,ect.The select of material will mainy depond on the application of its industry.At Fly Forge,we can take any design and metal into production with our advanced closed die forging process.And forged steel is the most common used material by our customer for its special characristics.

Forging dies manufacturing is the first step to start a forging part. We all know that forging can be generally classified into two types, open die forging and closed die forging. Open die forging is operated between flat dies or dies in a simple shape. This process is mainly used for large parts. In closed die forging, metal billet is deformed in upper and lower dies for desired shape and dimensions. Deformation occurs in the closed cavity under high pressures, which will achieve precision forgings with tight tolerances. So this process is widely used for the manufacture of simple as well as complex high strength precision parts,especially when safety factor is considered. As a closed die drop forging manufacturer, we would like to introduce the forging dies manufacturing for closed die forging parts in detail.

Before manufacturing of forging dies, we can not start the production process directly. Firstly, engineer need to know how to design the forging dies following the drawing of a new forging part. Design of forgings dies depends on the processing steps, nature of workpiece material, flow stress, working temperature, etc. All these factors need to be considered. Generally speaking, we need to calculate the volume of billet accurately to aviod under filling or excess filling. And selection of parting line(referring the lind where two dies meet) is also important. Sometimes for a forging part, there are several options to choose a parting line. And the best one is that the parting line can ensure the flow of material will be uniformly divided. In other words, forging is not feasible if there is no way to decide parting line, in this case, casting can be considered.
differences between forging and casting
Forging is processing way that putting pressure on metal blank by forging machinery, making it produce plastic deformation, in order to obtain certain mechanical properties, a certain shape and size of forgings. Forging can eliminate the as-cast osteoporosis of the metal, welded holes, and generally mechanical properties of forging is better than that of the same material of the casting.So for those important components that require to undertake high mechanical load, or working in serious conditions, in addition to simple shape rolling plate, or welding parts are available, all will consider forging process.

Casting is a metal forming process that melting the metal into certain requirements of the liquid and then pouring it into the mold,after cooling solidification,we can get desired shape and sizes.Production cost of blanks produced by casting is low.For complex shape, especially the parts with complex inner cavity, casting can show its economical efficiency more; At the same time, it has a wide adaptability,and has better comprehensive mechanical properties. But materials that needed in casting production and equipments (such as metallurgical furnace,sand mixing machine,molding machine, core making machine, shakeout machine, shot blasting machine, etc.) will produce dust, harmful gas and noise.Thus it will do harm to environmental.
Casting is the oldest metal processing process that first melting metals into liquid status, then pouring metal liquid in injection moulds, and cooling a while to obtain the required shape or dimensions. When products are not suitable for forging, casting is the economic method for blank shape. Especially for complex shape parts, casting can show its efficiency more.

Size and weight range of casting parts is very wide, almost unlimited metal species; Parts that have general mechanical properties, but also has comprehensive performance like wear-resisting, corrosion resistance, shock absorption, which is better than other metal forming methods, such as forging, rolling, welding, punching, etc. So metal blanks produced by the method of casting process are still the most on the quantity and tonnage so far.
Forging is a metal processing process that using forging pressure machines to put pressure on metal blank,which will produce plastic deformation in order to obtain certain mechanical properties,a certain shape and dimensions.Forging can eliminate the as-cast loose defects that produced on metal smelting process,optimizing the microstructure,and meanwhile can preserve intact metal flow.So mechanical properties of forgings generally are better than that of the same material castings.

As one of the main metal processing process,applications of forgings are so wide.Such forgings are mostly used by people when safety factor is considered and good mechanical properties are needed.So forgings can be used in mining machinery(mining drill bits),agricultural machinery(agricultural wear parts),forestry machinery(mulcher hammer/teeth),automotive industry,trailer parts,ect.Click our photo gallery page can help you to learn more about forging applications.

As a professional forging factory,like forged flail hammer,we can custom such flail mover clevis according to clients' drawings or samples,no matter what kind of shape and material specifications,we can all meet your demands.So,if you are in the flail mover industry,and have the purchasing plan for flail clevis,pls do not hesitate to contact us.
Flail hammer blades or Knives blades for flail movers"I would like to buy an Orsi 209 flail mover delivered with Y knives blades,but I preferred flail hammer blades. I'm just puzzlled which one is more suitable. I want to promote good pasture health in the paddocka,but also a nice finish on my lawn areas around the house.The flail mover will also be used for clearing of regrowth where there is a strong possibility of hitting tree stumps and branches, and small and large rocks. It will be much appreciated if any experience or opinions are provided."

When you design o buy a new flail mower, you will have a choice of the Y Knife Blades or Hammer Blades. The Y-Blades are great when cutting tall weeds and overgrowth and can also offer a nice cut to your lawn. However,if you are need to cut tree saplings and dense overgrowth,the flail hammer blades are used,which are wider, heavier blades than the Y-blades. No matter Flail hammer blades or Y knife blades,either set of blades will make a perfect solution for cutting.
In forging industry, there are some professional terms which are defined to describe the forging process or operations.Below we picked out some common terms when used in closed die forging process.

1) Forging die: It may be referred to a complete tool consists of a pair of mating members for producing work by hammer or press.A pair of forging dies consists of upper and lower die halves with cavities. 
2) Billet: A slug cut from rod ready to be heated and forged. 
3) Blocker: Preform die or impression, used when part cannot be made in a single operation. 

CFS company is specialized in supplying forged flail hammers in different sizes.In Eourpean&American market,most popular materials used in forged flail hammers are 42CrMo and 65Mn.By comparision,the price of 65Mn of forged hammers may be more competitive than that of 42CrMo.But as 65Mn belongs to spring steel,it will be very hard to forge flail hammers to final shape.Besides,to meet good durability,heat treatment(normally Quenching&Tempering) will be done to meet hardness 48-52HRC).And surface treatment of such products can be colour painting(yellow/black) or zinc plating,it mainly deponds on the demand of application.
When purchasers need a metal forming process for their precision design or products,they may have lots of considerations,such as quality,economy,ect.With the development of modern industry,there are all kinds of metalworking processes for choosing,such as casting,forging,powder metallurgy,stamping,machining,ect.Each metalworking process offers a unique set of costs,advantages and capabilities.When safty and strength factors are required,closed die forging process will be your best choice.In fact,closed die forging is often the optimum process,in terms of both part quality and cost-efficiency-especially for applications that require maximum part strength,special sizes or critical performance specifications.

In fact,in terms of forging,there are also several kinds of forging processes available,such as open die forging,closed die forging,cold forging,and extrusion.However,here we will discuss the methods,application and bennefits of closed die forging process.We suggest you to consider this process when selecting the optimum process for your metal parts production.
Closed die forging is commonly used in nowadays for many improtant metal components. On one hand, is that it can product metal products with good properties. On the other hand, the price of closed die forging is also competitive than casting. In other words, closed die forging also has economic advantages.


Before forging, we will first need to cut the equal billet according to the size of products. Normally, the waste of material after forging is the flash. So comparing with casting or machining, closed die forging requires less material, thus material cost will be saved. Take a round ring for example, we can make it by forging or machining. If machining, the all corner and the center material will be wasted. But with forging,we can forged to the sizes with minimum waste.
Linear dimension
Linear dimension,or size,it is to point to the distance between two points,such as diameter,radius,depth,width and height,center distance,etc.To express the dimensions of drop forgings exactly,lots of linear dimensions will be show in a drawing.After finish production of products,we will test all these linear dimensions by vernier caliper or digital caliper,to check if these dimensions are within the required tolerances.For outer diameter,it will be more accurate to use outside micrometers.

Angular dimensions 
Angular dimensions are usually shown the size of Angle,like 30,such angular is tested by universal bevel protractor.
To remove the stress and improve mechanical properties of drop forging, heat treatment will be done after forging. Such heat treatment can be normalization, tempering, quenching, temperting&hardening,ect.To test the heat treatment result,we may test the tensile strength,yield stength,enlongation,hardness,among these mechanical properties,hardness test is usually used for drop forging.Today,we will introduce common hardness testing methods for closed die drop forging.

Both briness hardness and rockwell hardness are all the testing standard for drop forging hardness.Although the testing methods of them are not the same.But either of them can be adapted to see the hardness result of drop forging products.To ensure correct testing result,for one drop forging product,we should testing the hardness in different sections and check if heat treatment of drop forging is done in a good way.
Although the cost of drop forging dies may be relatively high,for piece price, it is very cost-effective. With drop forging process, the metal products can not only be in a low cost, but also win tough and durable characteristics. So that is why people say drop forging has low recurring cost and is the most beneficial production method for long runs. Of course, small quantities can be also offered, but more economocal with increased volume. Compared to cast or machined process, drop forging can produce metal products with a high strength-to-weight ratio. Also, it has less chance of flaws and low injection rate.

So,when you are interested in sourcing for drop forging supplier. CFS Forge can be your one stop shop. Our quick turnaround times and impressed services are the best in drop forging industry.
Steel forging is a metal forming process of shaping metals using the compressive force.The steel forging process is a bifurcated depending on the temperature at which it is preformed.Steel forging helps in shaping of the molten metal onto desired shape and size.It is one of the essiontial techniques in industry that are majorly reliant on machineries.Steel forging has gone simpler with the time.Main classifications of steel forging are carbon steel forging,alloy steel forging,stainless steel forging.

The traditional ways of steel forging lacks in various aspects.From being low on durability to prone to corrosion,there are numerous drawbacks.Metal enforced with steel can go a long way in terms of durability and evading corrsion.Closed die forgings for precison components are high on tensile strength.The imposed metals are used in the forging process of disc and sleeves that make cost conscious and quality product.

closed die forging optionClosed die forging is a form of impression die forging that uses two or more dies.It does not depend on flash formation to completely fill the die.Material is formed in a cavity that allows little or no escape of excess material, thus placing greater demands on die design. More elaborate die designs provide for more complex shapes than the open-die forging process. A variety of metals and alloys cans be forged using closed die forging process.

Closed Die Forging is largely focused on extremely high quality applications.Closed die forged materials are required where strength,reliability and resistance to fatigue are top most considerations.As such,forged materials are found throughout the automotive,aerospace and defense industries. 
In our company,many closed die forgings are used for automotive industry.Closed die forging will make automotive parts in a more stable working station. CFS Drop Forge provided forging solutions for automotive components.Our aim is to offer automotive companies high quality products.

Before placing an order,you will first get several quotations from potential closed die forging suppliers,some are manufacturers and some are trading companies.Importing closed die forging from China has been a popular trend for clients for its price advantage.And it has been too easy for purchasing manager with the sign-off to pick the "cheapest" 
quote without understanding what quality and partnership he is getting.

What we would like to remind you is that it will be a big mistake if just choose your closed die forging supplier who provides you the cheapest quotation.Just as a Chinese going says:"You get what you pay for".For distance factor,foreign customers can only find closed die forging suppliers from search engine.It is not actual for them to visit the potential suppliers right away for high travel expense.So quotation is the most direct factor they can consider a supplier.As a closed die forging company,we suggest more consideration factors,for example,if the supplier is manufacturer or not,what the capabilities are,lead time,ect.All these factors will help you to choose a most suitable supplier in a comprehensive way.Well because that's what we have here and if we quote a customer for closed die forging,we must make it work and work to the best of it's ability for it to be a profitable and sustainable project.
Although closed die forging can produce the strongest steel parts and other advantages,there are only few closed die forging factories in China for its less application than casting.So lacking a good supplier for closed die forging parts has become a common problem for foreign clients.Today a customer from Australia contacted and told us that he is a forging distributor and as now they are getting more and more enquiries for these small closed die forging(mould forging) parts,but they do not have a good supplier.So they are in urgent to find such a supplier.

Closed die forging is a metal forging tecnology for precision parts. Such process is usually considered especially for safty factor because of its good performance and strength. So closed die forging is quite popular in producing automotive and non-automotive sectors. And we can see a lots of closed die forging factories in different scales all over the world, some are for steel forgings, some for aluminum forgings, and others are for copper forgings. There is no doubt that advantages of closed die forging over investment casting are obvious, so many people may put forward a question: "Are closed die forgings expensive?"
Closed die forging requires two or more dies for production, which are also referred to as tooling. These dies first must be manufactured with CNC machine to reach high accuracy. The billet will be heated up to proper temperature for well deformation and is then pressed or hammered between these dies.

The restriction of the metal flow inside the dies allows the production of parts that are more complex in shape than a part being produced by the open die process. Additionally, closed die forging process allows for closer tolerances than those produced in open die (see the difference between open die forigng and closed die forging). Relatively simple shapes can also be processed this way, but the decision is usually driven by economics and meeting some of the conditions listed below.
Our company customizes different kinds of closed die forging products,for instance,drive and axle components for the commercial automotive industry,drilling attachment for mining technology,forged fittings for oil and gas industry,as well as other complex geometrical structures for construction&agricultural machinery,offshore industry,aeroplane industry,ect.

Wide range closed die forgings with superior quality and reasonable price from our company bring us an excellent reputation all over the world,so we are now growing fastly and exporting products at an increased capacity.The use of high-grade steels means that our products offer a particularly long working life.

According to the advantages of closed die forging,it has become one of the main metal forming processes in modern manufacturing.For its wide range of material specifications and 
shapes,closed die forging can be useful for lots of metal components,such as componets for aeroplane,cars and heavy trucks,shipbuilding,ect.

With the characteristics of closed die forging,we can make precision components with different wall thickness,complex shapes,narrow tolerance.And we are all equiped with full range of machining equipments,so machining is also feasible in our company.Maybe sometimes you could also consider casting process instead,but by comparison,there  are both price advantages and quality advantages over casting,we will no need to worry about production defect.
automotive parts made by closed die forging
1. Background

Metals and alloys are able to be formed into desired shapes by plastic deformation.In deformation process,they also produce a wide range of properties particularly strength and toughness.The working of the metals into shapes by means of closed die forging methods refines grain structure,develops inherent strength giving characteristics,improves physical properties and produces structural uniformity free from hidden internal defects.What's more,the special feature of flow lines along the contour of the clsoed die forging produce marked directional properties.These features in closed die forgings give the automobile designers great confidence regarding the reliability of the vehicle.Learn more about advantages and disadvantages of closed die forging in detail...
Closed die forging is a metal forming process for small precision parts.We can take use of closed die forging process to desired shapes starting from steel billets.So closed die forging is widely used for all industries served for its unique advantages.Below are the advantages of disadvantages of closed die forging:

*After heating by medium frequency furnace,steel billets will be placed between upper and lower dies and forged in several times at high speed,so that the shape will be deformed quickly.Such press process will make internal grain flow and increase the tightness and strength of products.
*It is no scientific to say closed die forging is expensive for its high tooling cost.Tooling cost of closed die forging is actually higher than that of investment casting for its high die material cost and complex processing process.But for large production runs,we must say it is more cost-effective.
near net shape forging
Near net shape manufacturing technologies produce components that are close to the finished size and shape,requiring a minimal amount of finishing process such as machining.
Closed die forging is such a near net shape forging process that requires less or no machining.It will be helpful for us to save machining cost.

Why closed die forging is near net shape forging?

*Compared to machining process,closed die forging is a precision forging process with flash,so the only waste of material is just the flash section.We could also use machining to replace closed die forging process sometimes,but as the desired shape by total machining has be reached by machining equipments,so much of material will be wasted.

Closed die forging is also named as impression die forging.In impression-die work metal is placed between upper and lower dies that attached to the anvil.Usually the hammer die is shaped as well.The hammer is then dropped on the workpiece so that the metal flows and fills the die cavities.The hammer is generally working on the workpiece at the speed of milliseconds.Depending on the size and complexity of the part the hammer may be dropped several times in quick succession.Excess metal is squeezed out of the die cavities,we call this flash.The flash cools more rapidly than the rest of the material;this cool metal is stronger than the metal in the die so it helps prevent more flash from forming.This also forces the metal to completely fill the die cavity.After forging,the flash is removed by punching machine(Of course,trimming die will also first made together with forging dies).
The techniques of closed die forging are capable of achieving some of the strongest metal products when compared to other manufacturing processes.During the process of closed die forging,forging operations used can seal any cracks or empty spaces of the billet,therefore creating very strong metal parts.The typical method that can achieve this is known as closed die drop forging,which is when a plate of metal is placed between two dies,and then compressed under extreme pressure within the closed cavities to form the shape between the molds.The cavities restrict the flow of the metal inside the die (mold),and the metal will flow to fill the space within the cavity,resulting in the shape and dimensions of the mold design.Depending on the type of metal used,this process can be done while the metal is hot forging.

The Closed Die Forging process forces the material to flow and fill the space in the mold also changes the grain structure of the metal while making the product very strong.The flow is controlled in the direction what will achieve the strongest results and best grain structure.The high pressures of the process condenses the individual grains of the metal,resulting in higher density of the material and stronger properties.
It is a custom process for manufacturing drop forgings,so there exsits difficulty to develop a new product.We all know that there are different requirements for different products,some just require drop forging only,some require machining to reach tighter tolerances and some require heat treatment......So it is really unknown that if the potential suppliers we choose are suitable.If buyers would like to custom cheap drop forgings from China with good quality,it is really necessary for them to arrange a visit before ordering.

So when visiting,what should purchasers pay attention to?

*What is the scale of the company?
The scales of a forging company will decide its capability.A scaled drop forging company should have more than 80 staff.Like our company,there are about 150 staff,which is the largest drop forging company in Ningbo.It does not mean small scale drop forging company can not supply high quality products,at least its production ability is limited,and we can not say the lead time is ensured.
In recent years,more and more companies are used to manufacturing drop forgings from China.Then why do they like to do that?The most attractive point is that they can buy high quality production with low price.Normally,it is about 50%-60% cheaper to custom drop forging productions from Chinese drop forging companies than that of developed countries.Nowadays,for the improving of drop forging process,customers do not need to worry about quality problem.Take our company for example,to meet customers'demands of drop forging products in all applications,we are now equiped with ISO9001:2008,TS16949,API certifications.And we could not only supply drop forging blanks,but also machining can be provided also,so that we could custom finished drop forging products to our customers.
Steering knuckle is one of the main parts of automotive steering bridge, to be able to make the car driving stable and sensitive relay driving direction.One Role is to pass on steering wheel turning Angle value to the car front wheel effectively,timely control the car moving route,thus to ensure the safety of the car;Another effect is to bear load of 
the front car,supporting and driving wheels turn around the king pin,in the condition of the car moving,undertake variable impact load.So steering knuckle requires not only reliable strength,and must ensure its high machining accuracy.Its geometry is complicated,so the machining sections are more,the machining precision of high and low will affect the vehicle running accuracy.Based on the forging analysis of two different forging process of steering knuckle,discussing the influence of parting ways,distribution of allowance on machining processing.

Steering knuckle is the safety component of a car.It may cause heavy traffic accidents if there is any quality problem.The geometry of automobile steering knuckle is complex,belongs to compound type of forgings,consists of the fork,plate,bar of three parts.So the forging technology need to aspire to forming characteristics of three kinds of forgings.Steering knuckle is regards as the most complex forging parts in forging industry.

Now there are some car steering knuckle also increased the steering arm and tie rod arm,whose structure is more complex,the current steering knuckle is widely used in the van and light vehicle,also have individual heavy vehicles use this structure of steering knuckle.As shown is a light vehicle steering knuckle,its structure is very special,and its forging is difficult.Steering knuckle forging in the part was made by use of 3t,5t,10t die forging hammer,13 tm double-action hammer and some other forging equipments,but the production efficiency is low and product quality is poor.In recent years,auto production every year increases by double-digit growth,and the demand of steering knuckle is increasing rapidly,the old mode of production has not suitable for the needs of the modernization and mass production.
hot die forgingHot die forging press is a special forging equipment of batch production and mass production of black and non-ferrous metals that are used for closed die forging.It is widely used in automotive industry,agricultural machinery,bearings,valves,engineering machinery,hardware tools,oil industry and the forging of the defense industry production.Can complete closed die forging forming of metal parts like blade,horns,gears,chain plate,valves,wrench,bulldozer,connecting rod,ect.

There are mainly three series of hot die forging presses,namely NSP,NMP and NKP.Of course,there are also some auxiliary forging equipments,such as roll forging machine,trimming machine,heating machine,ect.

Characteristics of hot die forging press 

Hot die forging presses have advantages of high efficiency,simple operation,convenient maintenance,and suitable for automation forging assembly line.High blow speed,mould thermal contact time is short,and forging dies service life is long.Using upper and lower design will make draft angle decreasing and forging material saving.High resistance to tilt rate, lead to high precision guide rail and high quality steel forgings.PLC control,multiple safety operating circuit system,can ensure the operator safety.Left and right sides of the body is equipped with the work window,so that forgings delivery is convenient.Special card die liberation device,make release of dies rapidly,and the operation is simple.Reliable centralized lubrication system and manually add lubrication system,can effectively reduce the friction loss.Equipped with advanced international tonnage meter,can visual display forging force,and set the overload alarm.
forged connecting rod
Over the past 50 years,auto parts manufacturing technology is in the continuous improvement.Today,what takes a leading role in the market is the low cost,high strength anf tight 
tolerance.In drop forging production process,the strict requirements for forgings are just as important as to the requirements of the finished product.Drop forging companies 
around the word constantly look for a better production method to achieve the objectives and requirements of the auto parts buyers.

Forged connecting rods are regarded as the quality standards of internal combustion engine to use for decades.Over the years,production methods of connecting rods are constantly changed,includingforging hammer forging,press forging,metal powder forging and casting.In the early years of auto industry development,forging hammer forging is considered to be one of the best forging method.However,in the middle of the twentieth century,due to the higher requirements for quality and tolerance,the forging method must be changed,so manufacturers began to use mechanical press to replace forging hammer.The most effective way to reduce the manufacturing cost is to improve the material utilization.Increasingly stringent requirements for weight and size tolerance promotes the use of powder forging method.Another advantage in addtion to tolerance is that we could forge connecting rod cover toegther with connecting rod,and can open the cover from connecting rod,thus manufacturing cost can be saved.In the late twentieth century, forging method developed into "open" forged steel connecting rods(Why use steel for drop forged connecting rods in automotive cylinder engine?),it is also one of the strengths of the powder forging.The strength of forged steel connecting rod is higher than powder metallurgy rod.Increase as the engine compression ratio,compared with the powder forging connecting rod(wrought vs powder forged connecting rods),high strength of forged steel connecting rod becomes more satisfactory,this forging method can meet the both strict requirements of weight and size tolerance.

There are different types of forging processes,today our discussing topic is drop forging design.Before drop forging production,the engineering design team will first finalise the 
geometry,dimension,tolerance and material requirement(normally used material is drop forged steel) for the desired component.This is based on future application of the products,including the intended performance of the part.The typical output is a machine drawing of the final required part;which include post drop forging processings such as machining,tolerance and surface finish requirements.The drop forging drawing of the considered component is shown in Fig.1.1. And a 3D model displaying different views is shown in Fig.1.2. 

The first step for a production engineer is to convert the machine drawing into drop forging part drawing.Understanding of the function of actual part in service should be considered as a prerequisite to efficiently deal with this conversion phase.This understanding also helps to improve the decision making ability for the subsequent design stages.The selected component is a part of the universal joint used in propeller shaft for heavy commercial vehicle application.The component is known as “Flanged Yoke” in automotive terminology. It is mostly subjected to torsional loadings;as the whole propeller shaft is designed to efficiently transmit the engine torque to the rear axle. 
Automotive parts take up a great proportion in closed die forging parts.Application of closed die forging parts,include most of the engineering sectors including automotive.Primary aims of automotive manufacturers is to produce reliable vehicles that can bear load carring at a high speed.At the same time,closed die forgings should be lighter as possible in manufacturing to support fuel economy.Advantages of closed die forging that given by auto manufacturers are below:
  • Correct designed closed die forging parts for automotive application,can undertake higher loads and greater stresses than same manufacturing in other methods
  • Because close tolerances achieved in basic closed die forging process,further machining processing can be reduced or avoided.Thus,productivity is improved with a overall cost reduction.
  • We can achieve weight saving due to less wastage of drop forged steel and  the inherent characteristic of higher strength to weight ratio.
  • Less machining time will improve lead time for overall manufacturing process.
  • Any outer deformation caused by compressive load will ensure good performance in internal structure.
  • As billtes are impressed by dies,inside grain flow will improve properties such as strength,ductility,impact resistance,fatigue resistance,ect.
Closed die forging is one of the drop forging processes(another is open die forging),which is mainly for precion small parts using forging technology to achieve better surface finish and performance.In fact,the original name of closed die drop forging is impression die forging,closed die forging is just compared to open die forging.We call this process impression die forging because billets are impressed on the dies to get deformed to create a new part.

In closed die drop forging,two halves of dies are pressed together at a high pressure to shape a metal bar into desired dimensions.This is also a closed process as the dies completely closed together in times to form a part.Most commonly,this form of die forging is used to create 3D metal shapes, such as solid metal parts and other metal pieces that have a solid design and 3D shape. The metals most commonly used with this form of die forging include steel,aluminum,and titanium.
drop forged steelDrop forging products are served for a large number of industries, such as automotive, agricultural, mining,f orestry, oilfield, etc. Almong all the metal materials, most popular material is drop forged steel. It is widely used because it is a very strong and stable metal that can withstand high temperature heating by drop forging machines, thus can be shaped. Heating the drop forged steel to a high temperature by our medium frequency furnace because under room temperature, the steel is solid and we have no way to make the billet shaped. Only reach a certain temperature can we change the structure. The heated malleability of the metal combined with the force of the hammer shoving the metal against the die usually makes shaping drop forged steel relatively easy. Because of this ease of shaping the sheets of metal can be processed into their required shapes pretty quickly.
drop forging parts"Were looking for company to forge our PDR tool tips.Tools made from 4140 carbon steel.We need about 10" to 16" taper on one end,check our website out".This is a quote request for drop forging that was sent from one of our customers.From the requested information we know that the material is 4140,which is commonly used material in drop forging process.And the sizes of the drop forged tool tips are from 10" to 16",so we could judge that it is within our forging capacility,too large or too small is not available.

But to offer a quote completely,we still need to know if our customer could send us  the detailed 2d drawing or sample.Since we could do cost estimation of the product correctly,and especially need to note if there is any machining requirements,as machining cost will be added for any machining job,although we have machining capability.
For the advantages of drop forging,it is always used to make metal parts.Drop forging design is the first step for starting a new part,and such design will follow the application and assembling of products.And drop forging products will be compressed in a closed die upper and lower dies to get desired shapes,after that we will see trimming around the products,which will be cut in punching machine,then forging blanks will be born.So before put into production,designer should consider in a whole way for following aspects:

Parting line
The forging dies will decide the postion of parting line around the edges of drop forgings.So it is a important thing to determine the position of parting line.The choice of parting line will directly affect waste material,machining allowance.Designer should indicate the position of parting line in the forging drawing clearly.It is better that the parting line lies in one plane perpendicular to the axis of the die motion. It can be located such that one die half will be completely flat, and the line will surround the largest projected area of the piece. The angle of the surface at the parting line from the primary parting plane should not exceed 75°, in general, the shallower the angles,the better it will be. It is crucial for designer to select the parting line such that no undercuts are in either die impression,since the forging must be ejected out of the die after it is made.The parting line location can be changed to control the grain direction given the above recommendations are fulfilled.
Forging is defined as a metal working process that shape workpiece into desired dimensions by compressive forces applied through the use of dies and tools.Forging process is operated by hammering or pressing the metal.It is one of the oldest known metalworking processes with its origin about some thousands of years ago.At first,forging was complicated by a smith using hammer and anvil.Using hammer and anvil is a crude form of forging.The smithy or forge has been improved to become a facility with engineered processes,production equipment,tooling,raw materials and products to meet the demands of modern industry.

In nowadays,industrial forging is done either with presses or hammers powered by compressed air,electricity,hydraulics or steam.Some examples of products obtained by forging process are-crane hook,connecting rod of an IC engine,spanner,gear blanks,crown wheel,pinion etc.
In terms of materials,all the forgings are manufactured in steel,aluminum,cooper.From these materials,steel is most common used for its price advantage,easy purchasing and good performance.Following the large demands of steel forgings,more and more steel forgings plants are built,some concentrate on large steel forgings,while some prefer small steel forgings.Even if in China,we could see lots of steel forgings factories.So to compete with other competitors,it is quite important to be a good steel forging manufacturer.As we are professional drop forging company for small steel forging,so today the discussing target is precison steel forgings with closed die forging process.

1)Equipments:Production capabilities will directly decide the development of an enterprise.To produce steel forgings,there are several production lines consists of various forging equipments.It will require lots of money to invest for these equipments,so the investment for equipments is rather important as it will directly show the production capcbilities.Some small steel forging manufacturers choose to buy forging equipments from domestic market for lack of money.But it is not a wise choice in the long term as these equiments will have to be obsoleted after three years' working.However,some large steel forging manufacturers will prefer imported forging equipments from Japan,Korea,German,ect for their superior quality.Such imported forging equipments could be lasting for at least 10 years.
Differences between drop forging and press forging
Drop forging is when half of the die is dropped from a height onto the other half of the die,which will contain the hot metal workpiece to be formed. Drop forging is more suitable for mass production.Press forming is instead of dropping half the die onto the other half the two halves are put together and pushed together under a large pressure (up to about 10000 tons) forming the object.the difference is that drop forming leaves the centre of the metal not so hard as the outside,but press forming gives more uniform hardness for larger components.Of course,drop forging and press forging are defined in term of two kinds of forging methods.We could also differ forgings from its temperature,such forgings are named into cold forging,warm forging and hot forging.(See cold forging vs warm forging vs hot forging).
Forging formings of metals according to temperature can be divided into cold deformation (cold forging),warm deformation (warm forging) and thermal deformation (hot forging).The microstructure and mechanical properties influences on forgings of these different forging processes are also different.

1)Cold forging:refers to blanks processed below the recrystallization temperature.

Characteristics of cold forging:high dimensional accuracy,good surface roughness,good working conditions and high production efficiency.So cold forging can replace machining sometimes.Cold forging can make metal reinforcement,improve the strength of parts.So it is applicable to aluminium and plastic parts alloy, copper and alloys,low carbon steel,medium carbon steel,low alloy steel which the deformation resistance is small under room temperature.But when cold plasticity,metal deformation resistance is big,with poor plasticity,and contains accumulation of residual internal stress,needs to continue deformation after intermediate annealing.Nevertheless,the advantages of cold deformation technology makes it is more and more widely used.
forged connecting rodsConnecting rod is the key part of car engine parts, is also a typical and important complex closed die forging parts.Manufacturing fine degrees,inner and outer quality of connecting rods will directly affect the engine performance and level.Connecting rod causes high-frequency alternating stress inside in the high speed run up process of engine.It will have to bear shock pressure detonated by every stroke gas in cylinder and crankshaft torsional inertia force.When the hair motor's speed is 3000 ~ 5000 r/min, the loading frequency is very high.Because the connecting rod is working at high speed under the fatigue load,so,there is high requirement on the strength of the connecting rod.In addition,due to keep the crankshaft always operate at a high speed in an equilibrium state,so the weight of the connecting rod must also be controlled in a certain range.

Plastic forming and machining process of connecting rod are difficult,for the purpose of this forging production and machining process,which it is easy to appear the quality problem.The occurrence of these quality problems involve many factors. So for a long time,drop forging manufacturers are always continuously improving and discussing the material,forging process and mechanical processing manufacturing technology.Its purpose is to satisfy thetechnical performance and use requirements of products,and to be able to reduce costs,improve efficiency and increase economic benefits to the greatest extent at the same time.

Crank shaft is main rotating parts of engine, is installed on the connecting rod,can undertake the (reciprocating) up and down movement into circulation movement (rotation) of connecting rod. Is an 
important part on the engine, and its material is made of carbon steel or nodular cast iron, there are two important parts of crankshaft:main journal, connecting rod journal,(and other). Main journal is installed on the cylinder block, connecting rod connected with the big hole, neck connecting rod small hole is connected to the cylinder piston, is a typical slider-crank mechanism. Lubrication of the crankshaft is mainly refers to the lubrication of bearing between the rocker arms and the lubrication of two fixed point.The rotation of the crankshaft is the power source of the engine. Is also the driving force of the whole mechanical system.

Crankshaft fracture is the serious fault of the engine,and fracture usually occurred in the postions of connecting round corners between crank pin,main journal and the crank arm or other stress concentrated sections,like journal oil hole position.
drop forged conveyor chainConveyor chains are designed for chain conveyor system.There are different types of conveyor chains,inculding hollow bearing pin chain,solid bearing pin chain,deep link chain and drop forged chain.Today we are taking about conveyor chains made in our drop forging technology.Drop forged conveyor chains are also called en-mass conveyor chain or scraper chain,which is fitted with attachments welded onto chain links.Such drop forged conveyor chains are widely used food processing machinery,mining,agriculture,material handing industries,ect.So there are a  large demand for us to export them to overseas market.

Our drop forged conveyor chains are manufactured in our chinese factory from high grade alloy steel,such as 42CrMo.Of course,we could make custom forgings according to your special requirements on other materials and heat treatments for high strength and wear resistance.Our drop forged conveyor chains have standard type,double type and triple link type.
custom forgingsCustom forgings are the forgings made according to the drawings or sample from customers.Here the custom forgings we are talking about are using closed die forging method,not open die forging.Comparing with standard forgings,which have finished mold&dies developing,there is an extra cost for forging dies.In our company most drop forged products are all custom forgings excluding some standard high pressure pipe fittings.We are the manufacturer of custom forgings in China and could serve you custom forgings in high strength,close tolerance and low cost.Our forging buying guide will introduce buying procedure in detail.

Our capabilities for custom forgings
  • Weight range:normally we could customize closed die forgings ranging from 200g-30kg.Of course it is not definite,it is mainly decided according to the product structure,then we will see if our forging press could forge.
  • Machining capability:we have machining ablility as well.Our machining includes precision machining for forging dies,and rough machining for products after forging.
  • Industry served:all forgings applied in any industry can be customized.
  • Surface treatment:we could do any surface treatment as requested,most used surface treatment for custom forgings are painting,zinc plating,ect.
In our closed die drop forging products,there is a top demand for wears parts.So called "wear parts" refer to metal components assembled to these machines which work in rather serious woking condition,such as mining,forest,agriculture,and so on.And these wear parts will directly work in soft soil,sandy soil or rock environment.So most of them are designed in drop forging process with better mechanical properties,although the cost might be higher than made in casting.In addition,to meet maximum wear resistance,wear parts manufacturers will use tungsten carbide tiled to forged wear parts body,so that they will have a longer woking life and save cost.

Production process of tungsten tiled wear parts
*Dies making for forged wear parts-according to the structure of wear parts,engineer will decide if they are fitted for closed die drop forging and decide the split line,then machine the forging dies with our advanced cnc machines.Normally the tooling cost is higher than that of casting for its precision dimensions and die material,normally between 2000-3000usd.
closed die and open die forging
In modern society,forging industry is involved in various industries for construction machines,agricultural machinery,automotive,oilfield equipments,ect.Steel billets could be processed by various forging 
processes,among them the common used forging ways are closed die forging and open die forging.Although these two forging methods all belong to forging,it is not difficult to tell the difference between closed die forging and open die forging.The biggest difference of them is forging dies.Now let us have a deeper comparison on the differences between them.

Open die forging is also named free forging,means metal billets compressed under external compressive force and deformed to desired demensions or shapes in a free way without forging dies.Closed die forging,also referred to impression die forging,is a process that heated by medium frenquency induction heating furnace to high temperature and forged between upper and lower dies to get expected shapes like the drawing.
Although there are a variety of advantages of drop forging technology compared to other metal forming processes,there may still exsit some defects in hot forging process. Such drop forging defects can be split into two broad types:geometrical defects and non geometrical defects.

Geometrical defects of drop forging
*Laps and folds: Laps and folds are produced due to improper design of drop forging dies, making the laps created onto the final component which is rather undesirable as make irregular surface finish and also may weaken the product for internal or external cracks.
*Unfilled defects: There may exsit some sections of die cavity not completely filled by the flowing steel. This defects happen due to the improper design of drop forging dies or not using the right forging process.
There are different types of forgings, drop forging (closed die forging and open die forging), cold forging, samless rolled ring forging. So forging can generally divided into hot forging and cold forging. Cold forging is a forging process mufacturing in room temperature, however hot forging is a forging process in high temperature, so it is also referred to as drop forging. We can use hot forging to produce a wide range of parts in most metals. So we may be wondering why drop forging is hot forging, not cold forging?
hot forging
Forged steel is a forged process made in steel. Early forged steel types were developed in China and Persia. Traditionally, forged steel is manufacturered by a smith. Since 1800s, modern forged steel was started. To make forged steel, workers have to heat metals to high temperature so that it could be easily shaped into desired dimensions. Today forged steel is used in a number of industries.

Benefits of forged steel
  • Forged steel require an initial cost for the design and making of dies. But it has low recurring cost for each parts,so drop forging gradually become more economical with large volume.
  • During drop forging process, metals are shaped to follow the designed shape of part while its internal grain deforms. Then, the grain is continuous throughout the part and make forged steel parts with improved strength. Therefore, forged steel has higher strength to weight ratio compared to cast steel,at least 20% higher.
  • Forged steel is the right alternation of aluminum for its low cost in many applications. And forged steel has three times as strongth as aluminium although it is much heavier.
For the advantages of drop forging, such as it can bear high power,this process is widely used for all industrial manufacturing. In all the metal forming process, we can say drop forging is the best solution for your steel parts. So today more and more buyers use drop forging as the production process,especially for those components in large production runs. Most drop forging manufacturers supply OEM service for their customers, so buyers can forge any shapes they like, of course, such shapes must comply with drop forging technology and the dimensions can not exceed the range of the largest forging press allows. There are many drop forging companies all over the world, and buyer can choose to custom drop forgings in any countries (USA, UK, Australia, China,etc) they like. In comparison, they prefer to buying in China for the low price. But due to the lack of understanding of Chinese drop forging industry, buyers do not know how to make the parts in China.
forged fittingsDrop Forging is a processing method by use of forging press put pressure on metal blanks, making it produce plastic deformation in order to obtain certain mechanical properties, a certain shape and sizes. Forging can eliminate the as-cast loose defect produced during metal smelting process, and optimize the microstructure. Meanwhile because of the intact metal flow,the mechanical properties of forging will be better than that of castings in same material.

Main forged fittings include: elbow, flange, tee, union, coupling, cap, etc.

Main standard: American standard ANSI, German standard DIN, Janpanese standard JIS and Chinese GB/T, etc.
closed die forgingClosed die forging,also called impression die forging,involves the pressing or hammering of preformed metal blanks into a set of dies shaped as a three dimensional negative of the part to be produced.In closed die forging the hammer and anvil fully enclose the workpiece,forcing the metal to fill all areas of the die.Closed die forging can produce a nearly limitless variety of 3-D shapes, and is capable of producing complex parts with tight tolerances.

Closed die forging is distinct from open die forging, in which the die only comes into contact with part of the workpiece at a time.Initial costs for developing the processes and tooling for closed die forging can be quite high,but it is the most cost-effective forging method for high volume production,since recurring costs for each part are very low.In addition,closed die forging is capable of producing both symmetrical and non-symmetrical parts. Materials that frequently undergo closed die forging processes include high alloy steel, naval brass,carbon steel,aluminum,alloy metals,stainless steel,copper, nickel,tool steel and titanium.Closed die forgings are used particularly often by industries such as electronics,aerospace,automotive,commercial,manufacturing,semiconductor,construction,hardware and food processing.
Alloy steel is also one of the most commonly used metals for drop forging. This is because drop forged alloy steel is known for being stronger, more wear resistant and tougher compared to carbon steel drop forgings. Alloy steel is considered to be iron-based alloys that has been alloyed or mixed with a variety of elements in the range of 1.00 – up to 50.0% to enhance the physical properties. The combination of alloys and elements forged together is what determines the phyical strengths and properties of the metal. Common alloys added are chromium, molybdenum, manganese, nickel, vanadium boron and silicon.

To achieve these properties of increased stregnth, resistance and toughness, alloy steel drop forging is typically done by heat treatment,also known as hot forging.Our company maintains an extensive inventory of alloy steel.Our most popular closed die alloy steels to forge include 20Cr,20CrMo,30CrMo,35CrMo,42CrMo,ect.
agricultural machineryWith the development of economy,it has come true that mechanized production is now applied in agriculture. In the past, people have to plant crops by labour, which cost them much time and energy. Nowadays, we just need to finish all the works by agricultural machines, such as tractor, cultivator, chisel plow, air seeder, harvester, etc.

Agricultural machinery is one of the main industries we served for drop forging products. With over 10 years experience in exporting agricultural wear parts to overseas market, like Spain, Italy, UK, etc, CFS now could offer a completed forging solution for agricultural needs including product design, drop forged dies making, forging, machining, heat treatment, surface finish, assembling, package, delivery, etc. We now have the most advanced production lines in China, could serve agricultural forgings in different specifications so that it could fit for all machines. All our agricultural drop forgings are made for agricultural equipment manufacturers or agricultural wear parts dealers.
drop forged eye nutsDrop forged eye nuts and eyebolts are used for lifting&rigging application.They provide strong and predictable suspension points for overhead rigging systems.And drop forging process will ensure a consistent,safe fastener.We can custom eye nuts in different sizes ranging from 1/4"-2" with working load limits from 0.07t-16t.When using,we must note eye nuts can not work exceed the working load limit,and make sure the thread holes are clean and undamaged for fitting.

Of course,inspection of drop forged eye nuts is also very important.We should ensure that the products are regularly inspected and that the inspection should be done in accordance with the safety standards given in the country of use.This is required because the products in use may be affected by wear,misuse,overloading,etc.During using process,users should take in mind that Inspection should take place at least every six months and even more frequently.
Forged socket weld fittings are another kind of high pressure forged fittings we have made in our factory.A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve, fitting or flange. In contrast to buttweld fittings, socket weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.There are three pressure classes also:3000,6000,9000.Drop forging technology will help you to obtain good performance socket weld fittings,and you will no need to worry about any quality problem when using.As socket weld fittings can also be used in place of thread fittings,so there will exist much smaller leakage.Although they are used in many industries,but as socket weld fittings are not available for Ultrahigh Hydrostatic Pressure(UHP) in food industry,which may produce virtual leaks.Below is the dimension sheet of forged socket weld fittings we have in stock:
Threaded fittings are one of the oldest jointing methods used in piping systems.Similar to socket weld fittings,they are designed for small pipe diameters no more than NPS 2.Such threaded fittings are normally made in stainless steel or carbon steel.We can divide them into three pressure classes:2000,3000,and 6000.Forged threaded fittings are a kind of forged high pressure fittings widely used in low cost,noncritical applications like water&fire protection,industrial cooling water systems,ect.Currently,forged threaded fittings made in our company are 45° elbow,90° elbow,tee,cross,half couplings,full couplings,ect.Below are the detailed dimension sheet for forged threaded fittings we have developed:
high pressure forged fittingsDefinition:With the booming development of modern industry,pipe fittings are widely applied in almost all the industries as the connector for pipes,especially for mining industry,oil&gas industry,chemical machinery,shipbuilding industry,ect.Such fittings include:elbow(45°&90°),tee,cross,cap,half coupling,coupling,and so on.all these fittings must withstand high pressure,so we call them high pressure forged fittings.

Materials:Due to the corrosion resistance and rustless of stainless steel,so it is commonly adopted for manufacturing forged fittings.Main material specifications are SS304 and SS316.Besides,there also exsits another carbon steel material(A105) used in the production of forged fittings.
auger teethAuger teeth is assembled to drilling auger(earth auger) for digging post holes in construction machinery.We can divide auger teeth into auger gage teeth,auger wisdom teeth,auger chisel teeth,auger carbide wisdom teeth according to its special usage.

Benefits of drop forged auger teeth
  • Drop forging can produce auger teeth that is strongerthan an equivalent cast part.As the metal bar is shapes during forging process,its internal grain deforms to follow the general shapes of auger teeth.
  • Drop forged auger teeth respond more predictably to heat treatment and offer better stability.
  • No internal defects will produce after forging
  • Short lead time for large production runs
Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0% along with varying quantities of other elements such as tungsten,cobalt,and chromium. Generally in defining carbon steel, no minimum or maximum concentrations are quoted for these elements, although it is accepted that stainless steel does not qualify. In other words, concentrations of both the primary carbon and secondary alloying elements may be adjusted to suit the intended end purpose of the steel. For example, increasing the carbon content of the alloy increases its hardness while decreasing its ductility.Drop Forging is one of the oldest metal forming methods and involves repetitive manual or powered impact to force red hot steel into a certain shape.The metal is heated in medium frequency furnace and shaped between the two halves of dies to achieve its final form.
stump grinder teethWe all know that stump grinder machines are widely used in forest industry to remove tree stumps.Stump grinder works by a cutter wheel with carbide teeth fixed.And the hydraulic cylinder will control the cutter wheel moving and push the stump grinder teeth to grind the tree stumps.If you are the user or distributor of stump grinder machines,you must know the importance of shapening stump grinder(How to sharpen stump grinder teeth?).

So the quality of stump grinder teeth will decide the using time.A stump grinder tooth is design by drop forging and then braze a small piece of tungsten carbide to enhance the strength so that it can work longer.After that such teeth will be fixed to the cutter wheel.Below is a picture showing how the stump grinder teeth are fixed to the wheel.
lunette ring assemblingLunette ring is a metal component that is installed on the front of a trailer,then towed by a vehicle using a standard pintle hook.Normally the inside diameter is 3 inch,it can be mounted to a trailer tongue using a bolt-on installation.There are different kinds of lunette rings,which are designed according to the weight of trailer.

Established in 2001 as a manufacturer of forged lunettle ring, CFS company has grown to become a leading manufacturer of forged components for trailer industry.

forged elbowElbow is one of the commom pipe fittings applied in oil&gas industry.An elbow provides a change in material-flow direction. This adds pressure losses to the system due to impact, friction and re-acceleration.As product enters the inlet of the elbow, it typically continues moving straight ahead to the first (or primary) impact zone. The product is then deflected at an angle toward the outlet of the elbow. The deflection angle is determined by the elbow design, the product’s characteristics, the conveying velocity, and specific load (also called the product-to-gas ratio). In many designs, the product will hit one or more secondary impact zones before exiting the elbow.

Elbows can be divided into different degrees,45 degree and 90 degree.There are also different kinds of elbows sold in the market,like tube elbow,pipe elbow,reducing elbow,forged elbow,welded elbow,threded elbow,ect.Today we would like to talk about forged elbows.Forged 90° elbows are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.
Hammer unions are commonly used in oilfield industry to seal two pieces of pipe or hose together and connected by threads or welds.They are high-pressure threaded or welded connections with two halves,a threaded female half and a wing male half with swivel nut that fit together and seal upon turning and then hammering the nut half together with the threaded half.To fit different sizes of pipe or hose,corresponding types of hammer unions are designed.In most cases,they come in sizes from 1" up to 10" and in pressures from 1,000 psi up to 15,000 psi.We distinguish pressure ratings with diffierent colours.Below is the chart for complete pressure rating and color codes for each high presure hammer union availible.

Fly's hammer union nuts are produced using modern drop forging manufacturing techniques to attain first class workmanship and dimensional control.All these nuts will follow our quality control system.Besides,we will also design a fixture to test and ensure correct assembling.100% testing could be done as requested.
rigging shackleRigging shackle is a u-shaped metal piece with a clevis pin or bolt across the opening.According to its usage,such rigging shackles are designed into different types,like bolt type anchor shackles,screw pin anchor shackles,screw pin sling shacke,bolt type chain shackle,ect.Shackles are the main connecting link used in rigging systems,from boats,ships to industrial crane rigging.They are used for not only lifting,but also for securing loads, retrieval, fall precaution,and other activities.These shackles are made from high corrosion resistant stainless steel, carbon steel and steel alloy both self-colored and galvanized, which makes them capable of enduring years of tough rigging. However if not used properly you run the risk of not only breaking the shackle but injuring yourself or others.

Fly Forge is an authorized manufacturer for rigging hardware districtutor/dealer(shackle,wire rope clip,hook,eyebolt,ect).We can drop forge shackles in any type with stainless steel,carbon steel or other steels.Our in house heat treatment will greatly improve the strength of such parts.And assembling to be a whole is also one of the benefits for us to manufacture shackles for you.Currently,all our rigging shackles are exported to Europe and America region.Just pls contact us right now,no type limitation,no time limitation!
drop forged wire roper clipOnce wire rope is easy to be loose and looped back to form an eye,so wire rope clips are produced to fix the loose end of wire rope.We can also call wire rope clip a u-bolt clamp or u-bolt clip.A wire rope clip is made up of a u-bolt with a saddle secured by two bolts.Normally,at least two or three wire rope clips to be assembled to wire rope to secure the ends properly to the length of the roper.

While wire rope clips are not designed to be used in an overhead lifting situation (swage sleeves should be used instead), drop forged wire rope clips are a heavy duty wire rope clip that can be used for sustaining overhead loads. Examples include guy lines, support lines, scaffolding, etc. Drop forged clips are galvanized, meaning they have a heavy coating of a zinc solution that will hold up to worksite abuse and the elements for a long time. Drop forged steel are excellent for use as guy wire clamps for heavy duty guying applications because they are both strong and resistant to corrosion.
Tie rod ends are used in the steering linkage, steering knuckle pivot supports, and various hinge mechanisms. They connect the center link to the steering knuckle on cars with ordinary suspension systems and recirculating ball steering gears.Together with the ball joints, tie rod ends make sure the car steers left and right at the same time it is hitting bumps and potholes that might cause the wheel to travel up and down. 

The sleeve connects the inner and outer tie rod ends together and allows for adjustment when the front wheels are aligned.The outer tie rod ends are connected to the steering knuckle that actually turns the front wheels.The steering knuckle has an upper and lower ball joint that it pivots on and creates the geometry of the steering axis. It consists of an inner and outer end. The inner tie rod ends are attached to either end of the center link and are served as pivot points for the steering gear.
A rocker arm is one of the automotive parts in the internal combustion engine. As the arm is worked on by a camshaft lobe, it pushes open either an intake or exhaust valve. This allows fuel and air to be drawn into the combustion chamber during the intake stroke or exhaust gases to be expelled during the exhaust stroke. Rocker arms have been invested for more than two hundred years and Its function has been change littlesince then. During the developing of rocker arms, both the operation efficiency and production material are keeping improved. Many modern rocker arms are made of drop forging process with material 42CrMo or other alternative materials.

In many internal combustion engines, rotational motion is induced in the crank shaft as the pistons cause it to rotate. This rotation is translated to the camshaft via a belt or chain. In turn, lobes on the camshaft are applied to push open the valves via rocker arms. This can be achieved either through direct contact between a camshaft lobe and rocker arm or indirectly though contact with a lifter driven pushrod. Overhead cam engines have lobes on the camshaft which contact each rocker arm directly, while overhead valve engines utilize lifters and pushrods. In overhead cam engines, the camshaft can be located in the head, while overhead valve engines have the camshaft in the block. Both varieties are seen in the US, but regulations have contributed to the decline of overhead valve applications elsewhere in the world.
A control arm is a bar that has a pivot at both ends. A car has several, including the upper control arm and the lower control arm, which are arranged to form the letter A.Control arms are part of the suspension system. They attach suspension members to the chassis and manage the motion of the wheels so that it synchronizes with that of the body of the car. They work with bushings, which are cylindrical linings that reduce friction and restrain the auto parts from going every which way.

As a result, you are able to go on joy rides without feeling sick and dizzy, as there is control and smoothness in the movement of the car. The two bottom points of the control arms that form the letter A are attached to the frame of the vehicle while the top point is attached to the spindle. Three or four control arms are placed between the rear axle housing and the frame if you have coil springs in both the front and rear suspensions.Like other body parts, the control arms should also be lubricated at every oil inspection. Handling and steering could become erratic if the control arms are malfunctioning and the unsteady movements of your car could take away your riding comfort.
Connecting rod used in automotive is a major link inside of a combustion engine.It connects the piston to the crankshaft and transfer power from the piston to the crankshaft,then send it to the transmission.After finishing the design of a connecting rod,we could choose different materials and production ways.In most cases,connecting rod will be made in steel or aluminum.And we could consider investment casting process,drop forging process or powdered metallurgy.But according to its fuction,most purchasers will prefer drop forging process(see the differences between drop forging and investment casting),and the do precision machining.

When connecting rod applied in vehicle engined, investment casting is available. This type of rod is made just by pouring the molten steel into a mold, and then do machining to achieve finished parts. It is reliable for lower horsepower-producing engines and is the cheapest way to manufacture. Casting connecting rod can be used in almost each type of engine, from gasoline to diesel. But due to the shortage of casting process, defects may be easily produced. By contrast, drop forging is better.

ISO/TS 16949 certification in our company

As a leading drop forging supplier in China,our company successfully achieved the ISO/TS 16949 certifications in 2014 by the joint efforts of all staff.We are now able to customize all kinds of automotive parts with our advanced drop forging process.Such forged automotive parts are like forged connecting rod,york ends,tie rod end,rocker arm,control arm,ect.These forged automotive parts are mainly exported to USA,Germany,Australia,UK,Canada for automotive manufacturers or auto parts dealers.Thanks to our high quality,impressive service and competitive price,we are always keep good business cooperation with our customers.
Material is one of the main factors when designing a drop forging product. There are a lot of considerations for deciding material for a drop forging part. We should know the properties of all kinds of drop forging materials.

In general, drop forging materials are classified into steel, aluminum, copper. As our company is mainly focused on steel forgings. So we will study steel material in detail. Steel is an iron-based alloy with small additions of carbon and other elements that impart improvements in various properties. Steel is the most widely used materials of metals. It is the 
metal material that has the highest strength per unit cost. There are a wide range of steel compositions as well as a wide range of microstructures that can be produced. These ranges allow a large choice of properties to be achieved within the steel-alloy family. At low temperatures,the microstructure of steel is often in the ferrite plus iron-carbide phase field, whereas at high temperatures, the microstructure of steel is in the austenite phase field. The different phases indicate differences in crystal structure. Moreover, they indicate differences in properties. Drop forging is conducted in the austenite phase field.
With drop forging process, we could customize all kinds of metal components in different shapes. These parts are all applied in different industries, like agricultural industry, mining & tunelling industry, transportation equipments, oilfield industry, construction machinery, etc. In-house CAD/CAM and tool making capabilities enable us to manufacture specials and standard head forms on short lead times.

Agricultural machinery
Current mechanized production has replaced the original artificial production. Agricultural machinery parts occupy about 25% of drop forging production. Most of our drop forged parts in agricultural machinery are supplied to the distributors/wholesalers. Of course, we also supply parts for end agricultural machinery manufacturers or fammers, but no more than distributors. All our drop forging agricultural wear parts are all with high wear resistance. Besides this, we could also offer value-added brazing technoloy with tungsten carbide attached to add the strength. Commonly agricultural machinery parts in drop forging process are kinfe guards, tub grinder tips, flial hammer, chisel plow points, etc.
