It can remove dirt such as rust from the surface of the workpiece and form a very important basic pattern on the surface of the workpiece (the so-called rough surface). In addition, by changing the abrasives of different sizes, different roughness can be achieved, which greatly improves the bonding force between the workpiece and the coating and electroplating materials. Or make the bonding site stronger and better quality.
After heat treatment, sandblasting oxidation can remove all dirt (such as oxide scale, oil and other residues) on the surface of castings and forgings and the workpiece, and polish the surface of the workpiece to improve the smoothness of the workpiece and beautify the workpiece. Sandblasting can make the workpiece show uniform metal properties, make the appearance of the workpiece more beautiful, and achieve the role of beautification and decoration.
It can remove the tiny burrs on the surface of the workpiece, make the surface of the workpiece smoother, eliminate the harm of burrs, and improve the grade of the workpiece. In addition, sandblasting oxidation can form small rounded corners at the joint of the workpiece surface, making the workpiece more beautiful and accurate.
Polish the surface of various workpieces to make the surface of the workpiece more beautiful. Make the workpiece smooth and non-reflective. For some special-purpose workpieces, sandblasting can achieve different reflections or mattes at will. Such as stainless steel workpieces, wood furniture surface matt, ground glass surface patterns, and fabric surface texture processing.
