The benefits of sandblasting on metal surfaces are as follows

（1） Before coating and bonding, sandblasting can remove all the dirt on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (i.e. the so-called rough surface). Moreover, it can achieve different degree of roughness by changing the abrasives with different particle sizes, such as the abrasive of flying abrasive abrasives, so as to greatly improve the combination of workpiece and coating and plating materials power. Or it can make the bonding part more firm and the quality is better.

Remove rust and oil from clutch to enhance adhesion

（2） The cleaning and polishing of rough surface and workpiece after heat treatment can clean all dirt (such as oxide scale, oil stain and other residues) on the surface of casting and forging parts and heat treatment, and polish the surface of the workpiece to improve the smoothness of the workpiece, so that the workpiece can show uniform metal color and make the appearance of the workpiece more beautiful and beautiful.

Descaling of shell iron plate

（3） The burr cleaning and surface beautification of machined parts can remove the tiny burr on the surface of the workpiece, make the surface of the workpiece smoother, eliminate the harm of the burr, and improve the quality of the workpiece. And sandblasting can make a small fillet at the junction of the workpiece surface, making the workpiece more beautiful and more precise.

Deburring and flaring of castings

（4） To improve the mechanical properties of mechanical parts, after sandblasting, uniform and fine concave convex surface can be produced on the surface of the parts, so that the lubricating oil can be stored, thus improving the lubrication conditions, reducing the noise and increasing the service life of the machine.

（5） Polishing effect for some special purpose workpieces, sandblasting can achieve different reflection or sub light at will. Such as stainless steel workpieces, plastic polishing, jade polishing, wooden furniture surface Matt, frosted glass surface pattern, and fabric surface texturing processing.
