The difference between stamping and cold extrusion
Stamping is a method of forming a workpiece (stamping part) of a desired shape and size by applying an external force to a plate, a strip, a pipe, a profile, and the like by a press and a die to cause plastic deformation or separation. Stamping is for the purpose of punching (cutting after punching)
Cold extrusion is to place the metal blank in a cold extrusion cavity, and at room temperature, apply pressure to the blank through a fixed punch on the press to plastically deform the metal blank to produce a part processing method. Cold extrusion is for molding purposes (the purpose is to change the shape)
