Shot Blasting Process of Steel Wheel Rim

Working principle of shot peening

Use the high-pressure fan or compressed air as the power to eject the projectile with a diameter of~2.5mm to impact the metal surface. By improving the surface roughness, the paint film adhesion of workpiece painting can be improved.

It is widely used for matting and descaling metal surfaces, improving mechanical strength, fatigue resistance, wear resistance and corrosion resistance of parts, and eliminating residual stress of castings, forgings and weldments.
