Plastic mold rust occurrence and elimination method

Usually the cause of plastic mold rust is caused by overheating decomposition gas after melting, if happen during the suspended molding, plastic mold is corrosive gas mold rust around him. Therefore, after the stop injection molding, must be put on the skin with a clean soft cloth will die, must be closed when not molding mould, prevent other surrounding a gas injection machine caused by corrosion. Closed plastic mold, remember to butter, don't forget to plug the pouring into type, if long time stop when molding, should be within the cavity spray anti-rust agent, etc. , before the injection cavity with a soft cloth to put on the skin clean, confirm no rusty spot.

if there is a cavity surface with class carbide slag, caused the plastic mold rust, should be promptly eliminate; Molding materials generated carbide precipitation and decomposition often make mould wear or corrosion, use dry cloth wipe immediately once they are found out.

general within the cavity of the plating is conducive to rust, but is not fully effective, sometimes corrosive gas corrosion depth by coating the surface of the air hole, the method to avoid coating corrosion is often clean plastic mold.

mould zhongtong cooling water is easy to make plastic mould rust. Such as mold cooling below zero, the moisture in the air will be formed in the mold surface water, such as don't erase will rust. Although molding process does not dew, but stopped after molding, immediately produce condensate, the production process is best not to stop forming, even to stop, also should shut off the cooling water, dry and plastic mold surface.
