Sand Blasting

Sand blasting shoot sands (copper ore, quartz sands, emery sand, iron ore, hainan sands) on the parts, using compressed air as the power, make the appearance or the shape of surface change. Due to the abrasive impact and the cutting effect, the surface of the workpiece will get certain cleanliness and different roughness, then get better mechanical properties, which contribute to improving the fatigue resistance, the adhesion, and extend the durability of the coating, also help the flow of paint and decoration.

Sand Blasting vs Shoot Peening

1, The same power and different material.

2, Sand blasting eliminate the dirt on surface, and the surface gets a little destruction, then increase sharply the area, which improve the joint stress between the part and coating.

3, The surface has a basic color, after sand blasting, but due to the surface get coarse, and the light is reflected off, it get dark.

4, Shot peening removes the surface contamination, which results in less damage on the surface, then increases slightly area.

5, The surface also has a basic color, after shoot peening, but it has matte effect because of spherical surface and that part of light is reflected off.

Sand blasting is the perfect, effective, rapid, normal method. It’s free to choose different roughness for sand blasting.
