Dongguan precision casting rust is a chemical reaction produced by every metal product. For example, the stainless steel pots used in our daily life will also rust. Of course, precision casting products are no exception. It is inevitable that it will rust during use, which not only affects the appearance, but also affects the use. So get rid of it.
1. Projectile rust removal:
It uses the high-speed rotating granulator impeller blade to rotate the high-speed rotating granulator impeller blade, the abrasive is scattered to the surface of the steel casting, the abrasive flying at high speed, flying at high speed, impacting and rubbing the surface of the alloy steel casting, thereby removing the surface of the precision casting Corrosion and scale, etc.
The method has high efficiency, good rust removal quality, a certain roughness can be obtained on the surface of the alloy cast steel, which is conducive to coating film adhesion, low labor intensity, and light environmental staining. Manufacturers should give priority to this method.
2. Spray rust removal:
The compressed air processed by the oil-water separation process sprays the abrasive at high speed from the nozzle. The pressure of the compressed air is generally 4-0.6MPa. Dongguan Precision Casting uses high-speed mushrooms with pressure to produce friction and impact when they come in contact with alloy cast steel parts. Remove oxide scale and rust.
The method does not require a fixed position, has high efficiency, flexible spray points, no dead corners, and good quality. At the same time, the surface of the alloy cast steel obtains a certain roughness, thereby facilitating the adhesion of the coating film.
