Due to the impact of abrasive on the surface of workpiece and cutting, Sand Blasting Pot makes the surface of the workpiece to obtain a certain degree of cleanness and different roughness, the mechanical properties of the workpiece surface is improved, thus improving the fatigue resistance of the workpiece increases between it and the adhesion of the coating and prolong the durability of the coating, but also conducive to paint leveling and decoration, the surface of the oxide layer and impurities, noise removed, and the medium surface roughening, eliminate the residual stress and improve the hardness of the surface of the substrate, which is similar to Shot Blasting Machine.
