The stamping parts are obtained through shape processing method which will gain required shape and size by applying force on plates, strips, pipes and sections through punch presses and dies to make them realize plastic deformation or disconnect. The stamping parts are workpieces (stamping parts) that are obtained through shape processing method which will gain required shape and size by applying force on plates, strips, pipes and sections through punch presses and dies to make them realize plastic deformation or disconnect. The punching and forging are plastic processing (or press working), collectively called forging. The blanks for punching mainly include hot-rolled and cold-rolled steel plates and strips.
