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.

To defend countries, the military must constantly develop new defense technology and equipment that performs on and off the field. From Humvees and tanks to jets and satellites, military technology is more advanced than ever before, requiring detailed machinery consisting of extremely precise parts.


To keep existing machines running properly and to help design and prototype the military machines of the future, the military organizations use only the best manufacturing processes on the market to produce their parts and prototypes. One of these processes is forging.
A trailer hitch ball is bolted to your hitch's ball mount and provides the attachment point for your trailer's coupler. The ball allows the trailer to pivot to provide smooth turning while towing. Trailer hitch balls are sold in various shank lengths and diameters, ball diameters and weight capacities to meet your towing needs.

Fly Forge can customize all kinds of different hitch balls for your trailer application. Such hitch balls can be made in carbon steel, stainless steel and other steel materials. Our company can provide the service from tooling design, parts manufacturing to testing & package. With advanced production process, the quality from our factory is always guaranteed. With in house tooling and machining, we can supply qualified products in competitve prices. 
"We are in need of a supplier for a part forged in steel, of which we attach the flat with the characteristics that we need, the estimated consumption of the same is 5000 pieces a year. Are you able to supply us with these types of parts? Could we pass a quote? Please indicate cost of the part, cost of the tooling and deadlines for obtaining samples and production parts." This is an inquiry from our customer from Argentine Republic in automotive industry.

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.

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. 
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.
