How to classify moulds

Depending on the material being moulded

Hardware moulds, plastic moulds, and their special moulds.

Hardware moulds are divided into: including stamping moulds (such as punching moulds, bending moulds, deep drawing moulds, flanging moulds, shrinking moulds, heaving moulds, swelling moulds, shaping moulds, etc.), forging moulds (such as die forging moulds, upsetting moulds, etc.), extrusion moulds, extrusion moulds, die-casting moulds, forging moulds, etc;

Non-metallic moulds are divided into: plastic moulds, inorganic non-metallic moulds, sand moulds, vacuum moulds and paraffin moulds, etc.

Among them, with the rapid development of polymer plastics, plastic moulds are closely related to people's life. Plastic moulds can generally be divided into: injection moulds, extrusion moulds, gas-assisted moulds, etc.

According to the processing object and processing process can be divided into:

①Moulds for processing metals.

② processing of non-metallic and powder metallurgy moulds. Including plastic moulds (such as two-colour moulds, compression moulds and extrusion moulds, etc.), rubber moulds and powder metallurgy moulds, etc. According to the structural characteristics, moulds can be divided into flat punching and cutting moulds and cavity moulds with space. The moulds are generally produced in small batches and in single pieces.
