Injection mold after the completion of injection molding rust troubleshooting scheme

As we all know, rust mold can cause quality problems for the entire plastic part. Plastic molds are mainly made of tool steel. In the work, encounter corrosive gases, water and

Other substances that cause rust, thus precluding this problem.

(1) Gas produced by melting decomposition.

Some materials, when heated, produce volatile gases that are corrosive and will corrode the mold. Therefore, when the equipment stops working, use a soft cloth cleaning mold

Set and close the mold. If not used for a long time, spray the anti-rust agent in the cavity and apply the butter to the gate when closing the mold.

(2) Cooling water in the mold.

Cooling water is usually used in the mold for cooling, so there is more moisture around the molding equipment. If the mold cools below the dew point, moisture in the air will be in the mold

Water droplets form on the surface. If it is not wiped off in time, it is easy to rust. Especially after the mold stops working, condensate will soon be produced. So, when the molding stops,

The cooling water is also turned off and the mold is dried.

(3) cemented carbide produced during molding.

After the mold runs for a long time, the molding material precipitates and decomposes to form carbides, which often leads to mold wear, corrosion or rust. In this regard, if you find carbonization

If the substance is formed, it should be removed immediately.
