What Is Cold Forging?

A collective term for plastic processing such as cold die forging, cold extrusion, and cold heading. Cold forging is a forming process below the material recrystallization temperature, and it is a forging performed below the recovery temperature. In the production, it is customary to call the forging without heating the blank as cold forging. Cold forging materials are mostly aluminum and some alloys, copper and some alloys, low carbon steel, medium carbon steel, and low alloy structural steel with low deformation resistance and good plasticity at room temperature. Cold forged parts have good surface quality and high dimensional accuracy, which can replace some cutting processes. Cold forging can strengthen the metal and increase the strength of the part.

The development of cold forging technology is mainly to develop high value-added products and reduce production costs.At the same time, it is continuing to develop cutting, powder metallurgy, casting,

Cold forging process advantages

The cold forging process is a precision plastic forming technology, which has unparalleled advantages in cutting processing, such as good mechanical properties, high productivity and high material utilization. It is particularly suitable for mass production, and can be used as a manufacturing method for final products. (Net-shape Forming), has a wide range of applications in the transportation aerospace and machine tool industries.

Disadvantages of cold forging process

Material requirements are high; not suitable for a small amount of processing; mold requirements are high. ^[1]
