Applications

Applications: Applicable to shipbuilding heavy industry, automobile manufacturing, machinery manufacturing, bearing, aerospace, precision instruments, mold polishing and other fields.
Factors affecting the sandblasting effect:
1. Abrasive force: the higher abrasive force, the better effect of sandblasting.
2. Bulk density: the higher bulk density, the better effect of sandblasting.
3. Dust: the lower of dust, the better effect of sandblasting.
