    Application fields and specific cases of cold forging technology

    Cold forging refers to placing a metal blank into a die cavity in a cold state, and under the action of a strong pressure and a certain speed, the metal is forced out of the die cavity to obtain the desired shape, size and certain mechanical properties. pieces. Clearly, the cold forging process relies on the die to control the flow of metal and the mass transfer of the metal volume to form the part. It is an important part of precision plastic volume forming technology.
