A stamping die is a tool for metal working, and is generally used to machine a flat metal material into a part or product of a desired shape through a stamping process. The stamping die is generally composed of an upper die, a lower die and a guide device. The upper die is a part for applying pressure in the stamping process, and the lower die is a part for supporting a workpiece. The guide means is used to ensure alignment and stability of the upper and lower molds. The design and manufacture of the stamping die takes into account the strength of the material, the shape and size of the part, and the mechanical requirements required during the stamping process.

Stamping dies are typically made of hard materials such as steel and cemented carbide. The manufacturing process comprises numerical control machining, electric spark machining, polishing and other processes so as to ensure the precision and durability of the die. Stamping dies are widely used in the industries of automobile manufacturing, home appliance manufacturing, electronic product manufacturing, and the like.
