From the metal stamping process, common molds should have the following processes:
1. Blanking a die, creating a separate die from the material along a closed or open outline. If you often see the mold inside the blanking die, punching die, cutting die, notch die, trimming die, cutting die, etc., these are to play the role of punching, so collectively referred to as the die.
2. Drawing the die is the use of a die to draw the material into open hollows, or to make the hollows further change in shape and size.
3. Forming die is to directly copy the shape of the blank or semi-finished workpiece according to the shape of the convex or concave die, and the material itself only produces the partial plastic deformation of the die. Such as bulging die, shrink die, flaring die, relief forming die, flanging die, and so on.
4. The riveting die is the use of external force to connect or lap together the participating parts in a certain order and manner to form a whole.
