Sandblasting room

Sandblasting is a method of finishing the appearance with high speed movement of grit. It can remove oxidation, grease and varnish from the surface and obtain a more uniform quality of the surface. Subsequent processes can be welding, oxidation, coating, chemical heat treatment, phosphating, etc. Sandblasting can make the appearance of the workpiece residual compressive stress, and make the workpiece appearance quality uniform, can improve the fatigue strength of the workpiece. The effect of strengthening is worse than shot blasting, and the workpiece deformation is smaller than shot blasting.
