What are stamping parts?

Stamping is a forming and processing method that relies on press and mold to exert an external force on a plate, strip, pipe, and profile to produce a plastic deformation or separation to obtain the required shape and size of the workpiece (stamping).

Sheet Metal Stamping Parts Characteristics

 

Compared with castings and forgings, with thin, uniform, light, and strong characteristics. Stamping can increase rigidity by producing parts with stiffeners, ribs, undulations, or flanges that would otherwise be difficult to produce. Due to the use of a precision die, workpiece accuracy can reach micron level, and high repetition accuracy, consistent specifications, can be stamped out of the hole, boss, etc... a Stamping machine, cold stamping parts generally no longer by cutting or only need a small amount of cutting.

The precision and surface state of hot stamping parts is lower than that of cold stamping, but they are still better than castings and forgings. Stamping is an efficient production method. A composite die, especially a multi-station progressive die, can be completed in a press multi-channel stamping process to achieve fully automatic production from material unwinding, leveling, and blanking to forming and finishing. High production efficiency, good working conditions, and low production cost generally produce hundreds of pieces per minute.

Sheet Metal Stamping Process

Stamping is mainly classified by process, which can be divided into separation and forming. The separation process is also called blanking; its purpose is to make the stamping parts along a certain contour line from the sheet metal separation while ensuring the separation section's quality requirements.

The surface and intrinsic properties of the sheet metal for stamping greatly influence the quality of the finished product, which requires the thickness of the stamping material to be accurate and uniform. Smooth surface, no spots, no scars, no scratches, no surface cracks, etc. Uniform yield strength, no obvious direction; High uniform elongation; Low compressive strength ratio; Low work hardening.
