Metal stamping involves forming or piercing a piece of metal with a dedicated piece of tooling and stamping the piece with a mechanical or hydraulic press. During the metal stamping operation, the upper die is attached to the ram, and the lower die is attached to the stationary bolster. As the press is activated, the ram moves vertically towards the bolster to form the piece of metal over the lower die. Metal stamping presses can perform a diverse range of operations, such as blanking, piercing, coining, embossing, deep drawing, and forming as well as combinations of these processes.

The metal stamping process is ideal for making parts for valves, lighting, aircraft, aerospace, and inserts for molded rubber.
