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.
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.
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.
In order to constantly offer our customers cost and service advantages in services such as cold forging and even to expand them, we have built up a network with strong partners since the founding of our company. The well-established workflow with these partners guarantees an optimal price-performance ratio and enables us to meet even the very short-term wishes of our customers.
As a forging parts manufacturer, the company provides cold forged products.
