Stamping-at room temperature, the required parts are obtained by applying pressure to the material by using the die installed on the press to separate or plastically deform it.

Stamping die is an essential process equipment for stamping production and a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of dies. The technical level of mold design and manufacturing is one of the important symbols to measure the manufacturing level of a country's products, which largely determines the quality, benefit and development ability of new products.
