In industrial production, there are many types of molds. Generally, according to the different forming materials, forming processes and forming equipment, molds can be divided into two categories: "stamping molds" and "cavity molds".
1. Stamping die:
Stamping die is abbreviated as punch die. It is a die for stamping metal sheets or profiles, and it can also stamp some non-metallic sheets. The supporting forming equipment used is a press (punch). In the cold stamping production, there are many kinds of punching dies: according to the nature of the process, they can be divided into punching dies, bending dies, drawing dies, forming dies, cold extrusion dies, etc. According to the process combination mode, it can be divided into single process die, continuous die and compound die. According to the guiding mode of the die, it can be divided into non-oriented die and guided die. According to the materials used in the mold, it can be divided into steel die, steel die, cemented carbide die and low melting point alloy die, zinc-based alloy die, rubber die, etc. According to production adaptability, it can be divided into general die, combined die, special die, etc. According to the degree of mechanization, it can be divided into manual operation dies, semi-automatic dies and automatic dies...etc.

2. Cavity mold:
Cavity mold refers to a mold that fills metal or non-metallic materials into the mold cavity after heating or melting, and then forms a product part corresponding to the shape of the cavity after a certain pressure and cooling. Generally, it can be divided into the following types: plastic molds, die-casting molds, forging molds, powder metallurgy molds, rubber molds, glass molds, etc. In short, the mold is mainly made in industrial production to adapt to the processing of different types of parts. It is produced according to actual needs.
