The basic concept of cold stamping: First, the definition of cold stamping: It is one of the basic methods of plastic processing. It is a pressure processing method that uses a mold installed on a press to apply pressure to the sheet to deform and separate, so as to obtain parts with a certain shape and size. Because the sheet metal stamping at room temperature is called cold stamping. The hot forming process is to heat the steel sheet with an initial strength of 500-600MPa to the austenite temperature range (850°C), then punch it into the desired shape on a press, and quench it at a cooling rate of 20-30°C/sec.…
