The choices produced by this process include things like: fuel tanks, water tanks, mechanised enclosures, fenders, etc. In order to ensure the caliber of moulds and reduce production prices, the materials should have good forgeability, machinability, hardenability, hardenability, along with grindability; it should also possess small oxidation, decarburization sensitivity, in addition to quenching. Such as, some plastic toys, too several products. Therefore, under the premise of satisfying a use performance, the first choice involving low-cost, can use carbon steel will never use alloy steel, can use domestic materials would not have imported materials.. Deformation cracking tendency. Plastic mould to satisfy the working conditions: wear opposition, blanks in the plastic mould cavity plastic degeneration, along the surface belonging to the cavity both flow Plastic Injection Moulds and slide, so that the surface with the cavity and the material between the intense friction, resulting while in the mould due to wear and also failure. The mould meets that technological performance requirements, and the manufacturing on the mould generally undergoes several processes just like forging, cutting and heat remedy
