How to deal with corrosion and rust in stainless steel precision casting

Rust is a chemical change in precision casting products. For example, people live in stainless steel plates and mountain basins that may cause corrosion. Of course, the same is true for precision casting products. Rust is difficult to avoid in applications, which not only affects the appearance, but also affects Higher visibility. Therefore, stainless steel precision casting manufacturers find that corrosion should be dealt with? The 2 methods are as follows:

1. Rust removal: The centrifugal impeller of the shot blasting machine runs at high speed to disperse the abrasives onto the surface of the alloy steel castings. The abrasives fly very fast, affecting and rubbing the surface of the alloy steel castings to remove rust and oxide scale on the surface of the aluminum alloy precision castings.

This method has high efficiency and good rust removal quality. It can also obtain a certain surface roughness on the surface of alloy steel castings, which is beneficial to the adhesion of the paint layer. It has low labor efficiency and the natural environment dye is shallow. Therefore, precision casting manufacturers should first choose this method. method.

2. Sprayer rust removal: The soap is solved by the oil-water separator, and the abrasive is sprayed quickly from the nozzle. The working pressure of air compression is generally 4-0.6mpa. Precision casting manufacturers will use the friction and working pressure when the machine contacts alloy steel castings The impact force caused removes surface dirt and rust.

This method does not require fixed fixed parts, has high efficiency, improved injection point flexibility, no dead ends, and good quality. At the same time, the surface of alloy steel castings has a certain surface roughness, which is beneficial to the adhesion of the stainless steel precision casting paint layer and should be widely used.
