According to the forging temperature, it can be divided into hot forging, warm forging and cold forging.
According to the forming mechanism, forging can be divided into free forging, die forging, ring rolling, and special forging.

Forgings used in most industries are hot forging. Warm forging and cold forging are mainly used for forging parts of automobiles and general machinery. Warm forging and cold forging can effectively save materials.

Forging materials are mainly carbon steel and alloy steel with various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original state of the material includes bar stock, ingot, metal powder and liquid metal.
