MAN-MACH's Automatic Shot Blasting Machine accomplishes the cleaning and peening of material surfaces by means of the shot blasting process. The working principle is to use high-speed projectile impact on the material surface, not only to efficiently remove oxidation, rust, old coatings and other impurities, but also to allow the material surface to form a moderate roughness, thereby enhancing the adhesion of coatings and material fatigue resistance. This stone shot blasting machine equipment is widely used in metal structures, bridges, ships and other industries, can effectively extend the service life of the material, enhance product quality and safety.
