First of all, in the process of producing products by injection moulding, the temperature in the Crate Mould is generally higher, so the steel for plastic mould injection made by plastic mould injection manufacturers must be the mould steel after high temperature tempering treatment, so that the overall designed mould size will not be affected even in high temperature environment, thus ensuring the overall precision of the mould.

Secondly, in the process of injection moulding, the raw materials of plastic products, such as resin and various additives, will corrode the surface of plastic mould injection moulding, thus affecting the overall precision of plastic mould injection moulding. Therefore, corrosion-resistant steel must be used in the selection of mould steel.

Generally, plastic products have higher requirements on surface glossiness, so in the production process of injection moulding, the surface roughness of the corresponding plastic mould cavity is required to be relatively small, so that plastic products meeting the standard can be processed by injection moulding. Therefore, mould steel without impurities and pores must be selected, and the surface of the mould cavity must be polished and ground after the plastic mould is manufactured.

In the process of producing plastic products by plastic injection moulding, because the plastic raw materials flow at high speed in the cavity of plastic injection moulding, it will cause great friction on the surface of the whole mould, so it is necessary to choose wear-resistant mould steel to ensure that the quality of products remains stable in the mass injection moulding process.
