Advantages of aluminum shell bead blasting process

Advantages of aluminum shell bead blasting process:

Removing surface oxide film: bead blasting treatment can remove the oxide film on the surface of aluminum shells, whether naturally formed or anodized, which can be removed by bead blasting treatment. This is usually done before the anodizing process
Enhanced coating adhesion: The surface of the aluminum shell after bead blasting treatment can enhance the adhesion of the coating. Whether it is electroplating or spraying treatment, it can significantly improve the adhesion of the coating
Improving mechanical performance: The surface of the aluminum shell after bead blasting treatment can increase the smoothness by 0.5-1, and there are small depressions on the surface that can store lubricating oil, thereby extending the service life and reducing mechanical operation noise
Removing small burrs: bead blasting treatment can effectively remove small burrs on the surface of aluminum shells, especially suitable for precision parts such as 3C communication components, textile machinery parts, aerospace precision parts, and medical device spare parts
Addressing the issue of metal reflection: For aluminum products that strictly prohibit reflection, such as surgical instruments, bead blasting treatment can effectively solve this problem
Disadvantages of aluminum shell bead blasting process:
High cost: bead blasting treatment requires a large amount of abrasives, such as copper ore sand, quartz sand, etc., which increases production costs
Environmental impact: Dust and noise pollution will be generated during bead blasting, and appropriate protective measures need to be taken
Surface roughness control: The surface roughness after bead blasting is difficult to accurately control, which may affect subsequent assembly and functionality
