Steel shot sandblasting is mainly used for finishing the surface of parts. It uses a high-speed rotating impeller to run the zhuan steel shot out to collide with the surface of the metal product to achieve the effect of removing the oxide layer of the part.
When the steel shot quickly hits the surface of the casting, it will form the distortion of the crystal lattice on the surface of the casting, which can strengthen the surface hardness of the metal, which is also a way to improve the appearance of the casting. Sandblasting is often used to treat the surface of castings or strengthen the appearance of castings
