Stamping process classification

Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, and its purpose is to separate the stamping parts from the sheet along a certain contour line, while ensuring the quality requirements of the separation section. The purpose of the forming process is to plastically deform the sheet without breaking the blank to make a workpiece of the desired shape and size. In actual production, multiple processes are often integrated into a workpiece. Blanking, bending, shearing, deep drawing [4], bulging, spinning, and straightening are the main stamping processes.
