Metal stamping is a processing method that applies external force to metal sheets, strips and other materials through presses and dies to cause plastic deformation or separation.

Metal stamping is an important process in modern manufacturing and is widely used in many fields such as automobiles, home appliances, and electronic equipment. It can produce parts with complex shapes, high precision, and high strength, and has high production efficiency and high material utilization.

Classification and characteristics of stamping process

Separation process: including punching, cutting and trimming, etc., the purpose is to separate the stamped parts from the sheet along a certain contour line. This process is widely used in industries such as automobiles, home appliances, and electronics, accounting for about 50%-60% of the entire stamping process.

Forming process: including bending, drawing, bulging, etc., the purpose is to make it plastically deform without destroying the material, and make the workpiece of the required shape and size. These processes can be applied to a workpiece in combination to produce stamping parts with complex shapes and high precision.

Cold stamping and hot stamping: Cold stamping is performed at room temperature and is suitable for sheets with low deformation resistance and good plasticity; hot stamping requires heating of the material and is suitable for sheets with high deformation resistance and poor plasticity. Hot stamping can effectively solve the forming problem of high-strength steel sheets.
