According to the different molding materials, molds can be divided into metal molds and non-metal molds. 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 are closely related to people's lives. Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds. Mass production of non-sheet metal steel parts-cold heading, die forging, metal molds and other molds
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.
But I think the mold industry is saturated.
It is recommended not to learn mold!
It is better to learn the mold and come out to sweep the streets, and the salary is pitifully low. The monthly salary is only a few hundred dollars!
And the prospect of the mold is not so good!
Now the mold market is saturated, and there is basically no development prospect!
It takes a lot of time to learn mold, and it's hard to learn!
It is generally a training school to say that molds are good!
Hope to choose carefully!
You'd better not learn mold!
