How To Eliminate Injection Molding Die Rust? -- DGMF Mold Clamps Co.,Ltd

The injection mold is mostly made of tool steel, and it will encounter corrosive gas, water, and other substances that cause rust in the work. Plastic parts made from rusty molds will cause quality problems, so they need to be eliminated.

 Gases generated by melt decomposition

Some raw materials produce volatile gas after heating, and many raw materials also produce volatile gas when overheated. These gases are more corrosive, and they diffuse around the machine. When the mold is not working, they will corrode the mold.

In this regard, when the machine stops working, use a soft cloth to clean the mold, and close the mold. If it is not used for a long time, the mold cavity should be sprayed with a rust inhibitor. mouth.

Cooling water in the mold

There is more cooling water in the mold to wake up the cooling, so there is more moisture around the machine. If the mold is cooled to a dew point, the moisture in the air will form water droplets on the surface of the mold, and if it is not wiped off in time, it will easily rust.
