What is stamping?

Stamping is the processing which need put external force to plates, strips, pipes and profiles by presses and molds, and it would make them plastic deformed or separated, then we will obtain the work piece with the required shape or size. The main blanks of stamping are hot-rolled and cold-rolled steel plates or strips.


Stamping

Stamping Process


The die used for stamping is called stamping die, or die for short. The die is a special tool which batch processing materials (metal or non-metal) into the required stamping parts. Punching dies are vital in stamping. The mass stamping production will be difficult, if without a die that meets the requirements. The advanced stamping processes cannot be realized neither, if without advanced stamping dies. The stamping processing is constituted by the stamping process and die, stamping equipment and stamping materials. Only when all of these elements are worked together, the stamping parts could be made out successfully.

Stamping Raw Material

Stamping

There are 60% to 70% steel plates among all of these steels in the world, and most of them are stamped into finished products. Such as the car body, chassis, fuel tank, radiator fins, boiler steam drum, container shell, motor, electrical iron core silicon steel sheet, etc. All of them are stamped and processed. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, and living utensils.


Stamping

Stamping Mould


Stamping is an efficient production method. If using compound dies or multi-station progressive dies, multiple stamping processes can be completed on one press (single-station or multi-station). In this way, it will realize fully automatic production from strip uncoiling, straightening, flattening, blanking to forming and finishing. Stamping has high production efficiency, good working conditions, and low production cost. Generally, stamping could produce hundreds of pieces per minute.

Stamping Equipment


However, stamping forming processing has the some disadvantages either.

(1) High noise and vibration;

(2) The mold requires high precision, complex manufacturing, long cycle, and expensive manufacturing cost. So small batch production is restricted;

(3) If the precision requirements of the parts are too high, it is difficult for the stamping production to meet the requirements.
