Rust is precision casting products will be produced by a chemical reaction, such as we normally live in the basin of stainless steel and can produce corrosion, of course, the precision casting products are no exception, will inevitably be in the use of rust, not only affect beautiful, more influence, so precision casting factory found rust should remove? The two methods are as follows:

1. Projectile derusting: the impeller blade of the projectile blasting machine rotates at a high speed to disperse abrasive to the surface of alloy castings, and abrasive flies out at a high speed to impact and friction the surface of alloy castings, so as to remove rust and oxide on the surface of alloy precision castings.

This method has high efficiency, good quality of rust removal, and it can also make the surface of alloy castings obtain a certain roughness to facilitate the adhesion of paint film, low labor intensity, and light stain to the environment. Precision casting manufacturers should give priority to the use of this method.

2. Jet rust removal: abrasive will jet with high speed from the nozzle with compressed air separated with oil and water. The pressure of compressed air is generally over 4-0.6mpa.

This method does not need a fixed location, high efficiency, injection point flexibility, no dead Angle, good quality, at the same time to make the alloy cast steel surface to obtain a certain degree of roughness, to facilitate the adhesion of paint film, generally should use this method.
