Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the steel in the world is sheet material, most of which is stamped into finished products. The body, chassis, fuel tank, radiator fins of a car, the steam drum of a boiler, the shell of a container, the iron core 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 and meters, household appliances, bicycles, office machinery, and daily utensils.
