| (1) Sand blasting for workpiece coating and pre-bonding of workpieces can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called matte surface). By changing the abrasives with different particle sizes, such as the abrasives of Feizhan abrasive tools, the roughness of different degrees is achieved, which greatly improves the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality. |
(2) Cleaning and polishing of the rough surface of the casting and the workpiece after heat treatment The blasting can clean all the dirt (such as oxide scale, oil stains and other residues) on the surface of the casting and forging, and the workpiece after heat treatment, and polish the workpiece surface to improve the finish , Can make the workpiece exposed to the uniform metal nature, make the appearance of the workpiece more beautiful and good-looking.
(3) Deburring and surface beautification of machined parts. Sand blasting can clean the tiny burrs on the surface of the workpiece, make the surface of the workpiece more flat, eliminate the harm of burrs, and improve the grade of the workpiece. And sandblasting can make small rounded corners at the interface of the workpiece surface, making the workpiece more beautiful and more precise.
