Today, Hongyang will join you all month to learn how to safely remove rust from precision castings produced under precision casting technology.

1. Spray rust removal

The compressed air treated by oil-water separation sprays the abrasive at high speed from the nozzle. The pressure of the compressed air is generally shielded at 4-0.6MPa. Precision casting uses high-speed friction with pressure to generate friction and impact when in contact with alloy cast steel components, removing oxide skin and rust.

2. Shot rust removal

Using high-speed rotating granulator impeller blades to rotate, abrasive scatters onto the surface of cast steel parts, and the abrasive flies at high speed, impacting and friction the surface of alloy cast steel parts, thereby removing corrosion and oxide scale on the surface of precision castings.
