Metal stamping is a mass metal processing technology, which uses stamping tools to manufacture sheet metal parts by pressing materials into the desired shape. This is done according to a pattern, and each part is removed from the motherboard after stamping. Metal stamping can produce thousands to millions of parts in one run. This is more productive than other metalworking processes, such as CNC machining, manufacturing or welding, which are well suited for mass manufacturing. Metal stamping is a common metal processing technology. The products are pressed and formed by stamping machine. It has the characteristics of high production efficiency, high product uniformity and low start-up cost. This has unique advantages for the production of some hardware products, and the hardware parts with stable quality can be mass produced at a lower cost.
