How to prevent plastic molds from rusting?

If the plastic mold is placed for a long time without professional treatment, it will affect the life of the plastic mold. The reason why the plastic mold will rust is caused by the gas generated after the melt is overheated and decomposed. So how to prevent plastic molds from rusting?

First of all, when the injection molding stops, wipe the plastic mold products with a clean soft dry cloth.

Then, when the processing mold has not been formed, you must pay attention to closing it. The advantage of this is mainly to avoid corrosion caused by the gas generated by the surrounding injection agent. When closing the plastic mold, it is best to apply butter.

Finally, when the molding is stopped for a long time, spray anti-rust agent in the mold cavity. It should be noted that before spraying, the mold cavity must be wiped clean until there are no rust spots.
