2.Overview of metal stamping process
2.1 Basic Principle
Metal stamping process refers to the processing method of using a mold to exert pressure on a metal sheet in a press to produce plastic deformation or separation, so as to obtain parts or products of the desired shape and size. The process mainly includes basic processes such as punching, bending, deep drawing, expansion and flanging.
2.2 Process Flow
The typical flow of metal stamping process includes material preparation, mold design and manufacturing, stamping processing, post-treatment (such as deburring, cleaning, heat treatment, etc.) and inspection. Among them, the design and manufacture of the mold is the core of the stamping process, which directly affects the quality and production efficiency of the product.
