There are many kinds of moulds:

Mold manufacturers can be divided into:

① A mold for working metal.

② Processing non-metallic and powder metallurgy mold. Including plastic mold (such as two-color mold, compression mold and extrusion mold), rubber mold and powder metallurgy mold. According to the structural characteristics, the die can be divided into plane blanking die and cavity die with space. Moulds are generally produced in single pieces in small batches.

According to the different materials formed:

Hardware mold, plastic mold, and its special mold.

Hardware molds are divided into: stamping dies (such as blanking dies, bending dies, drawing dies, flanging dies, shrinkage dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.), extrusion dies, extrusion dies, die-casting dies, forging dies, etc;

The non-metallic molds are divided into plastic molds, inorganic non-metallic molds, sand molds, vacuum molds and paraffin molds.

Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic mold can be generally divided into injection molding mold, extrusion molding mold, gas assisted molding mold, etc.
