How to prevent rust in precision casting

The methods to prevent rust of precision cast iron parts are as follows:

Select appropriate materials: During the manufacturing process of castings, selecting appropriate materials with corrosion resistance is the first step in preventing rust.

Surface treatment: Surface treatment is one of the effective means to prevent castings from rusting. Through methods such as plating, coating or anodizing, a protective layer can be formed on the surface of castings to effectively isolate external moisture and oxygen and reduce the risk of corrosion. occur.

In addition, there are other methods such as adopting new oil-free anti-rust processes.
