Application Of Shot Peening And Sandblasting Technology

Shot and sand blasting is mainly used for surface treatment of metal products such as steel
1. Before coating and bonding the workpiece, sandblasting can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern (commonly known as rough surface) on the surface of the workpiece. Moreover, by exchanging abrasives with different particle sizes, different degrees of roughness can be achieved, greatly improving the adhesion between the workpiece and the coating and plating material. Or make the bonding parts more firm and of better quality.
2. The cleaning and polishing of rough surfaces of castings and forgings, as well as the cleaning and sandblasting of workpieces after heat treatment, can clean all dirt (such as oxide skin, oil stains, etc.) on the surface of castings and forgings, and polish the surface of workpieces to improve the smoothness of the workpiece. This can make the workpiece expose a uniform and consistent metal color, making the appearance of the workpiece more beautiful and achieving the function of beautification and decoration.
3. Machined parts burr cleaning and surface beautification sandblasting can clean small 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. And sandblasting can create small rounded corners at the interface of the workpiece surface, making the workpiece appear more beautiful and precise.
4. Improve the mechanical performance of parts. After sandblasting, mechanical parts can produce uniform and fine concave and convex surfaces (basic diagram) on the surface of the parts, allowing lubricating oil to be stored, thereby improving lubrication conditions and reducing noise, improving the service life of the machinery.
5. For certain special purpose workpieces, sandblasting can achieve different reflective or matte effects at will. For example, the surface of stainless steel workpieces and wooden furniture is matted, the patterns on the surface of frosted glass are patterned, and the surface of fabric is textured.
