If the hot stamping forming process is used for automobile stamping parts, the benefits it can bring are mainly to realize the lightweight production of automobiles, and to effectively improve the strength of stamping parts. Moreover, it is molded at high temperature, so it has the advantages of high molding accuracy, high molding performance, etc., and there is no springback problem. The auto parts that can be used are the anti-collision beams, safety parts and car body structural parts.

If the stamping parts are formed by hot stamping, what are the main processes?

Stamping parts, if they are formed by hot stamping, then, in the specific process, mainly include the following, which are:

Blanking: That is, the sheet is punched into the desired outer contour blank for subsequent processing.

Austenitizing: It consists of two stages of heating and holding. The purpose of its processing is to heat the material to a suitable temperature so that it has good plasticity.

Transfer: The heated material is taken out of the heating furnace and then sent to the thermoforming mold. The key point is that the speed should be fast. If the speed is too slow, it will affect the quality of the stamping parts.
