（1） Firstly, the stamping process of metal nameplates relies on the use of presses and molds to apply external forces to plates, strips, pipes, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining the desired shape and size of the workpiece (stamped part) through forming processing

（2） Stamping and forging belong to plastic processing (also known as pressure processing), collectively referred to as forging. The raw materials for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the world's steel is sheet metal, most of which are made into finished products through stamping

（3） The body, chassis, fuel tank, radiator fins of automobiles, steam drums of boilers, shells of containers, iron cores and silicon steel sheets of motors and electrical appliances are all stamped. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machinery, and household utensils.
