Cold-Heading Process / Roll-Forming Small Metal Parts
Cold-Forming Overview. Cold-forming or cold-heading is the application of force with a punch to a metal blank staged in a die. The force exceeds the alloy’s elastic limit, causing plastic flow until the metal blank assumes the shape bound by the punch and the die. As the name implies, this method of metal part forming is achieved by force
