The Character of Cold Forging Manufacturing Processes

Cold Forging Manufacturing Processes is a net shape forming process. The parts formed by this method have high strength and accuracy, and the surface quality is good. At present, the total amount of cold forging of an ordinary car abroad is 40~45kg, in which the total number of tooth parts is more than 10kg. The cold forged gear can reach more than 1kg with a single tooth weight of 7.

The continuous process innovation has promoted the development of cold extrusion technology. Since 1980s, precision forging experts at home and abroad have begun to apply the theory of split forging to cold forging of spur wheel and spiral gear.
