Cold Forging Parts Cold Forging Parts

Cold forging in China is a metal production process of forming technology in which bodies of various shapes are produced from steel blanks, disks or bar sections. When forming, the material is displaced at room temperature from an open die or a press bushing by the pressure of the press ram, wherein a change in cross section occurs - the workpiece is plastically deformed.

Pressed parts produced by this process are characterized by extremely high strength and special surface quality. Parts that will be indispensable in the automobile of the future despite their lightweight construction and new materials.

Which materials are suitable for cold forging parts?

For cold forging, steel grades are suitable which, when annealed, have a low yield strength and a high elongation at the lowest possible flow curve.

The special strength characteristics of cold forged products

Due to the strain hardening during forming a substantial change in the strength properties takes place during extrusion. Hardness, breaking strength and yield strengths are dramatically improved, while elongation and breakage are reduced. Thus, low-carbon strength steels are achieved, which equates to alloyed steels. The fatigue strength and durability of cold-extruded workpieces is significantly higher than from machined, sintered or even welded components.
