There are many types of moulds
According to the processing object and processing process they can be divided into.
①Moulds for processing metals.
② moulds for processing non-metals and powder metallurgy. These include plastic moulds (such as two-colour moulds, compression moulds and extrusion moulds), rubber moulds and powder metallurgy moulds. 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 single pieces and in small batches.
According to the different materials to be 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, undulating 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.
