The principle of wireless aluminum filled alloy support sandblasting is to strike hard and small diamond sand particles on the surface of aluminum shell through sandblasting machine to form uniform small pits on the surface, making it look fine and even to the naked eye. The advantages of sand blasting process are not only this, but also:
1. Remove the oxide film on the surface of the wireless aluminum filled alloy shell. The naturally formed oxide film can be completely removed after sand blasting. This is also the reason why the sand blasting process is prior to the anodic oxidation process.
2. Prepare for other surface treatment processes. When the wireless aluminum filled alloy bracket after sand blasting is oxidized, the bonding force of the oxide film is stronger.
3. Improve the mechanical properties of aluminum parts. The aluminum parts after sand blasting can increase the smoothness by 0.5-1. There are also small depressions on the surface of the parts that can store lubricating oil. This makes the lubrication effect better, so as to extend the service life of aluminum parts and reduce the noise of mechanical operation.
4. After spraying, the tiny burrs on the surface of the aluminum alloy shell can be removed to obtain a smooth and clean surface.
