Our Precision Sandblasting Services
Deliver uniformly textured surfaces (Ra 3.2–6.3μm) through controlled abrasive propulsion, ideal for pre-coating preparation or standalone matte finishes.
What’ is Sandblasting?
A compressed air system accelerates abrasive particles (e.g., aluminum oxide, glass beads) at 60–120 psi to mechanically alter surface topography. Key variables include:
Media selection: Angular steel grit (40–65 HRC) for aggressive descaling vs. spherical ceramic beads for delicate polishing
Mesh grading: Standard #120–220 grit range balances efficiency and finish quality
Impact angle: 45°–90°adjustments for tailored surface profiles

Sand blasting Advantages
- Superior adhesion – Creates 50–100% improved coating bond strength vs. untreated surfaces
- Multi-material capability –Processes ferrous/non-ferrous metals, composites, and architectural materials
- Environmental compliance – Recyclable media and dust containment systems meet ISO 14001 standards
Notes
- Default #120 grit achieves 2.5–3.5μm roughness; finer grades (#220) produce sub-2μm finishes
- Media lifespan: Steel grit withstands 8–12 cycles before replacement
Sand blasting Applications
- Automotive: Brake caliper cleaning
- Medical: Implant texture modification
- Construction: Historical facade restoration
