The cold forging process has significant advantages. On the one hand, production efficiency has been greatly improved. The traditional cutting process needs to gradually remove the material, the process is complicated, and the cold heading process is one-time forming, which greatly reduces the processing time. On the other hand, the utilization rate of materials has been significantly improved. In the process of cold heading, the metal material is mainly plastic flow, rather than a large number of cutting losses, which effectively reduces the cost. At the same time, the precision of cold heading products is very high, the size error can be controlled in a very small range, the surface is smooth, and the quality is far higher than that of ordinary processed products.
