The mold can be divided into metal molds and non-metal molds.

A mold is a production tool that can produce parts with certain shape and size requirements. That is, the molds that people usually say, such as mobile phone cases, plastic chairs, etc., are produced by injecting plastic heating software into the mold for cooling. The rice cooker is also pressed  precision mold manufacturing  into a shape by a metal plate mold. Many goods are now made with molds. In addition to hand-made and certain foods, it can be said that there is no production of the product without the mold. So how is the mold made? First of all, it is designed by the mold designer according to the requirements of the product, the mold structure is designed, the drawings are drawn, and then the technical workers can process all the parts on the mold according to the requirements of the drawings, and then assemble and debug until they can Produce qualified products, so mold workers need to master very high and comprehensive knowledge and skills, molds are good, product quality is good, mold structure is reasonable, production efficiency is high, natural factory benefits are good. How many molds do you have? The mold can be divided into metal molds and non-metal molds. First, metal molds: casting molds (non-ferrous metal die-casting, steel casting), and forging molds. Second, non-metal molds: plastic molds and inorganic non-metal molds. Third, 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. Fourth, with the rapid development of polymer plastics, plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds and so on. In addition, there are large-scale production of non-sheet metal parts - cold heading, die forging, metal molds and so on. Mold sheet metal discharge--hot rolling, cold rolling, hot coil, cold coil sheet metal processing--draw, shape, bend, punching, blanking non-ferrous metal--casting, powder metallurgy plastic parts--injection Blow molding (plastic bottles), extrusion (pipe fittings) molds Other classifications: alloy molds, sheet metal molds, plastic molds, stamping molds, casting molds, forging molds, extrusion molds, die-casting molds, automotive molds, rolling molds.
