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.
