Process:

Cold forging is an "impact forming" process that deforms a piece of raw material plastically, under high compressive force, between a punch and a die using suitable equipment such as a machine press. Cold forging forms the existing material into the desired shape as compared with conventional machining, which uses a removal process to take away material to create the shape.

Benefits:

The high compression process used in cold forging actually displaces and reforms the grain of the base material such that any inherent weaknesses are eliminated. This can be particularly important for part designs where the required shape could experience weak points along the existing grain of the base material.
