Mould can be divided into metal mould and nonmetal mould. Metal molds are divided into: casting molds (non-ferrous metal die casting, steel castings) and forging molds; Non-metallic molds are divided into plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds and people consult encyclopedias.

Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds. big

Mass production of non-sheet metal steel parts-cold heading, die forging, metal die, etc. mould

Sheet metal discharging-hot rolling, cold rolling, hot rolling and cold rolling sheet metal processing-stretching, forming, bending, punching, blanking non-ferrous metals-die casting, powder metallurgy plastic parts-injection molding, blow molding (plastic bottles), extrusion (pipe fittings) molds Other categories: alloy molds, sheet metal molds, plastic molds, stamping molds, casting molds, forging molds, etc.
