Why do metals need to be sandblasted?

 The sandblaster machine uses compressed air as the power to form a high-speed jet beam to spray the spray material on the surface of the workpiece to be processed at a high speed so that the mechanical properties of the outer surface of the workpiece surface are changed. Due to the impact and cutting action of the abrasive on the surface of the workpiece, The surface of the workpiece has a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, and extending the coating film Durability is also conducive to the leveling and decoration of the coating, removes impurities, mottled colors and oxide layers on the surface, and at the same time roughens the surface of the medium, makes the surface residual stress of the substrate and improves the surface hardness of the substrate.

1. Sandblasting equipment can remove all the dirt on the surface of the workpiece before coating and bonding the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface), and can pass Changing the abrasives of different particle sizes, such as flying-spread abrasives, can achieve different degrees of roughness, which greatly improves the bonding force between the workpiece and the coating and plating. Or to make the bonding part stronger and better quality.

2. Mobile sandblasting equipment Cleaning and polishing of the rough surface of castings and workpieces after heat treatment. Sandblasting can clean all dirt (such as oxide scale, oil stains, etc.) on the surface of castings and forgings and workpieces after heat treatment, and polish the surface of the workpiece to improve the workpiece The smoothness of the workpiece can make the workpiece show a uniform and consistent metal color, and make the appearance of the workpiece more beautiful and beautiful.

3. The sand blaster machine machining parts burr cleaning and surface beautification sandblasting can clean up the tiny burrs on the surface of the workpiece, and make the surface of the workpiece smoother, eliminating the hazard of the burr, and improving the quality of the workpiece. And sandblasting can make small round corners at the junction of the surface of the workpiece, making the workpiece more beautiful and more precise.

4. Small sand blasting machine improves the mechanical performance of the parts. After the mechanical parts are sandblasted, they can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing noise, and increasing the service life of the machine.

5. Automatic sandblasting machine light decoration function For some special-purpose workpieces, sandblasting can achieve different reflective or matt at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade, the matting of the surface of wooden furniture, the pattern on the surface of frosted glass, and the texturing of the surface of the cloth.
