How to avoid plastic mold rusting?
How to avoid plastic mold rusting? Typically the mould rusting is caused by the gas produced by the melt overheating decomposition. If happened in molding, that is because the corrosion gas existing around rusts the mould. For this reason, we must use a dry and soft cloth to clean the mould when injection molding stops. If don't need molding production, we should close the mould to prevent gas generated from other injection machines cause corrosion. When close the mould, please remember to paint grease and do not forget to plug into the pouring type. If do not use the mould for a long time, we should spray anti-rust agent in the mould cavities. And make sure you have cleaned the cavity inside before painting If there is coated carbide slag on the cavity surface, should be immediately removed. The carbide separates out and decomposes from molding material can easily get mould corrosion, so once discover, we should clean with a dry cloth. Usually the plating layer in th...
