What is the cold heading process

Cold heading is a major method of processing fasteners during the molding process. Cold heading technology uses metal pressure processing, metal at room temperature, the force generated by the deformation under external action, and the redistribution and transfer of the metal shape produced by the mold to form the required part or rough processing method threaded fastener Made from cold heading.

Advantages of cold heading

1) High material utilization rate. Cold heading or no cutting method, high material usage and less waste.

2) High production efficiency. The deformation time and process of metal products are relatively short, which can greatly improve productivity.

Disadvantages of cold heading

Cold heading can produce a workpiece which is very close to the final product size. But there are more things in the cold head. The important influence data is that the diameter ratio of the finished product is difficult to exceed 3:1, but if the appropriate mold can process more than 3:1 aspect ratio of the product.
