Definition: The forming method of applying external force to the blank to make it produce plastic deformation to change the size, shape and performance, which is used to manufacture blanks and mechanical parts. It is a general term for forging and stamping.
Forging is the combined name of forging and stamping. It is a forming processing method that uses the hammer head, anvil block, punch of forging machinery or through the mold to apply pressure to the blank to produce plastic deformation, so as to obtain the required shape and size of the part
Classification: Forging is mainly classified according to the forming method and deformation temperature. According to the forming method, forging can be divided into two categories: forging and stamping; according to the deformation temperature, forging can be divided into hot forging, cold forging, warm forging and isothermal forging, etc.
