What is stamping process?

Definition of stamping process

Stamping processing is one production technology, which is by feat of the power of conventional or special stamping equipment, to make the sheet metal to deform under a deforming force in the stamping mold, obtain the products with certain shape, size and performance.

Sheet metal, stamping mold, stamping equipment are the three elements of stamping process.

According to the stamping processing temperature, it can be divided into hot stamping and cold stamping. Cold stamping proceeds at room temperature, and is the common stamping process method for the sheet metal fabrication.

Feature of stamping process

– Stamping process is with high production efficiency, easy to operate, and easy to achieve mechanization and automation.

– Since using the stamping mold, to ensure the dimension tolerance, and out-look of the products, so stamping process is with solid quality and good interchangeability.

– Stamping process can process the item with large size range and complex shape requirement. As small as the second hand of a clock, as large as car stringers, covers, etc.

– Stamping process is with less material waste, so the cost is lower.

The material requirement of stamping process

– With accurate and uniform thickness.

– With smooth surface, no spot/ scar/ scratch/ surface cracks, etc.

– With uniform yield strength, no obvious direction.

– With high uniform elongation.

– With low ratio of the yield limit to the strength limit.

– With low work hardening.

Application of stamping process

Application of stamping process is very wide, such as in aerospace, military, machinery, agricultural machinery, electronics, information, railway, post and telecommunications, transportation, chemical, medical equipment, daily electrical appliances and light industry and other departments have stamping processing.
