What Is Sheet Metal Stamping?

What is sheet metal stamping? Sheet metal stamping is a metal processing method, which is based on metal plastic deformation. It uses die and stamping equipment to apply pressure to the sheet material to cause plastic deformation or separation of the sheet material, thereby obtaining parts (stamping parts) with a certain shape, size and performance.

The stamping forming process occupies an important position in the automobile body manufacturing process, especially the large covering parts of the automobile body. Because most car bodies have complex shapes, large structural sizes, and some are still curved surfaces with high surface quality requirements, the use of stamping processing methods to make these parts is unmatched by other processing methods. Almost all of the truck's cab, front sheet metal parts, freight car panels, various body covering parts of passenger cars and various skeletons of passenger cars are made by stamping processing methods.

The stamping process can be divided into four basic processes:

Punching: It is a stamping process (including punching, blanking, trimming, cutting, etc.) to achieve the separation of the sheet material.

Bending: It is a stamping process that bends the sheet material to a certain angle and shape along the bending line.

Deep drawing: It is a stamping process that transforms a flat sheet into various open hollow parts or further changes the shape and size of the hollow parts.

Partial forming: It is a stamping process (including flanging, bulging, leveling and shaping processes, etc.) that uses various local deformations to change the shape of the blank or stamping.
