• Free Forging (Open Die Forging)
  • Free ForgingFree forging, a kind of forging process, utilizes impact force or pressure to make metal deformed freely in any direction between the upper and lower anvil face, without any restriction to obtain the desired shape and size as well as a certain mechanical properties. Metal parts are worked above their recrystallization temperatures, ranging from 1900°F to 2400°F for steel, and gradually shaped into...
  • Die Forging
  • Die ForgingDie forging uses dedicated mold to make metal forming. This forging process provides a near shape of the part with a powerful grain structure. Since the basic shape of the part is obtained by pressure, much less material is lost in the forging and secondary machining processes. This closed die forging creates parts that are stronger than castings, but much cheaper than being completely machined ...

Forging Process Products

Forging technology offers uniformity of composition and structure. The forging process requires a forge furnace to heat the steel to sufficient temperature such that work hardening or strain hardening will not result from the deformation process. The metallurgical recrystallization and grain refinement results from the thermal cycle and deformation process. This strengthens the resulting forging products particularly, in terms of impact toughness and shear strength.
Forging process is to make parts by shaping metal under pressure to create a finished shape. Each piece is heated, and then shaped until the final product reaches exacting specifications of our clients. The forgings are much more reliable for strength and quality than similar products made by casting process, stamping or machining process.
Forging technology can be divided into free forging and die forging.

Advantages of Forging Process Products
1. The tight grain structure of forgings makes them mechanically strong. There is less need for expensive alloys to attain high strength components.
2. The forging technology can deal with impact better than the casting process.
3. The nature of forging process excludes the occurrence of porosity, shrinkage, cavities and cold pour issues.
4. The forging products are generally much tougher than alternatives.

Forging Process Flows
1. The general sequences of forging technology are as follows: laying-off of forging billet, forging stock heating, roll forging standby billet, die forging taking shape and trimming.
2. Intermediate inspection is carried out to check the size and surface defects of the forging products.
3. The forging process adopts heat treatment technique to remove forging stress and improve the performance of metal cutting.
4. The common forgings should go through appearance and hardness measurement, and the important ones need to conduct chemical composition analysis, mechanical properties and residual stress testing as well as non-destructive testing.
5. The cleaning step is to remove the surface oxidation layer of the forging products.

Materials of Forging Process
Raw material is stored under roof. All raw materials are fully traceable. The materials can be used for forging technology include carbon alloy, stainless steel, brass, bronze aluminum and nickel alloys.

Quality Assurance for Forging Process
The trained inspection personnel in our quality assurance department maintain complete control of each order. This begins with the receipt of material, and continues to carry out heat treating, secondary operations and final inspection. Nondestructive testing is performed in plant. Physical testing to ASME, ASTM and military specifications is available. The end result is a superior product, custom crafted to the exacting standards of our customer.
