Forging Parts Manufacturers and Forging Services

AS PRECISION provides forging parts service with machining integrated, we have our own tooling team to open forging molds and tools, and we have thread rolling machines accordingly for most forging threads. No matter how is your product shape, we can advise the forging processes professionally.

AS PRECISION-Forging Parts Service

Forging Parts Service, a manufacturing process of shaping metal by mold, using localized compressive forces, it is usually proceeded with forging tools like hammers or presses. The hammer is attached to an anvil, during the forging process, it is raised and dropped onto the work-piece to add force, this will step-by-step to forge out the shape needed. The most common types of forging processes are cold forging and hot forging.

“Metal forging services” include forging steel parts and sometimes aluminum or titanium. The advantages of forging include: faster forming speed, harder workpiece, easy CNC machining, minimal waste of material…etc.

Forging process can bring material into needed shape quickly, in crazy high speed but in rough precision. For forging products, normally we need to continue with machining processes on them, such as punching, threading, grooving, polishing and so on.

What Is a Forging?

Forging parts is a processing method that uses a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size. Forging (forging and stamping) is one of the two major components.

Through forging, defects such as as-cast looseness generated in the metal smelting process can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. 

For important parts with high load and severe working conditions in related machinery, forgings are mostly used in addition to rolling plates, profiles or welded parts with simple shapes.

Type of Forging

According to different production tools, forging technology can be divided into free forging, modular forging, ring rolling and special forging.

Free forging: refers to the processing method of forgings that use simple universal tools or directly apply external force to the blank between the upper and lower anvils of the forging equipment to deform the blank to obtain the required geometric shape and internal quality.

Die forging: Refers to the forgings obtained by pressing and deforming metal blanks in a forging die bore with a certain shape. Die forging can be divided into hot forging, warm forging and cold forging. Warm forging and cold forging are the future development direction of die forging, and also represent the level of forging technology.

Ring rolling: refers to the production of ring-shaped parts of different diameters through special equipment ring-grinding machines, and is also used to produce wheel-shaped parts such as automobile hubs and train wheels.

Special forging: including roll forging, cross wedge rolling, radial forging, liquid die forging and other forging methods, which are more suitable for the production of parts with special shapes.

According to the forging temperature, forging technology can be divided into hot forging, warm forging and cold forging.

The initial recrystallization temperature of steel is about 727 °C, but 800 °C is generally used as the dividing line, and hot forging is higher than 800 °C; between 300 and 800 °C, it is called warm forging or semi-hot forging. Processed at room temperature called cold forging.

Applications of Forging

Forging Parts can use pressure on a metal blank to deform it plastically and change its mechanical properties. The looseness of the metal can be eliminated by forging. Holes, so that the mechanical properties of forgings can be improved. Forgings have the following uses:

①General industrial forgings refer to civil industries such as machine tool manufacturing, agricultural machinery, farm implement manufacturing and bearing industry.

②Forgings for hydro-generators, such as main shaft and intermediate shaft, etc.

③ Forgings for thermal power plants, such as rotors, impellers, main shafts of retaining rings, etc.

④ Metallurgical machinery, such as cold rolls, hot rolls and herringbone gear shafts.

⑤Forgings for pressure vessels, such as cylinder body, kettle ring flange and head, etc.

⑥ Marine forgings, such as crankshaft, tail shaft, rudder stock, thrust shaft and intermediate shaft, etc.

⑦Forging machinery and equipment, such as hammer head, hammer rod, hydraulic press column, cylinder block, pillar and cylinder block of wheel press machine, etc.

⑧ Modular forgings are mainly forging dies for hot die forging hammers.

⑨Forgings for the automotive industry, such as left and right steering knuckles, front beams, couplers, etc.

⑩Forgings for locomotives, such as axles, wheels, leaf springs, crankshafts of locomotives, etc.

⑪Forgings for military industry, such as gun barrel, door body, breech block bracket and traction ring, etc.
