Stamping is an important processing method for plastic forming of metal materials. 60% to 70% of metal parts in automobile manufacturing are stamped parts, and the stamping process has a direct and significant impact on the quality and cost of automobile manufacturing. The operation of stamping processing is convenient, the production efficiency is high, and it is easy to achieve mechanization and automation.

1. Separation process Separation process is a basic stamping process that separates stamped parts from sheet metal along a certain contour line through a mold, also known as punching process. It can directly produce flat parts or prepare blanks for other stamping processes.

2. Forming process: The forming process is a stamping process that causes plastic deformation of the sheet metal in the mold without breaking, and produces parts of the desired shape and size.
