Sandblast
Sandblasting (Matte Texture)
High-pressure abrasive media impacts surface to create uniform matte texture. Removes scale, rust, and prepares for coating.
Key Parameters
Thickness
Salt Spray
Base metal rating
Wear Resistance
Medium
Recommended Base Materials
Pre-treatment for powder coating, decorative matte finish on aluminum
Factory Work Sequence
1
Media selection: glass bead for peening, aluminum oxide for etching
2
Pressure regulation at 2-4 bar for consistent coverage
3
Post-blast cleaning with compressed air and degreasing
Advantages
- Creates uniform matte texture that improves coating adhesion
- Effectively removes mill scale, rust, and welding discoloration
- Versatile media options (glass bead, aluminum oxide, steel grit) for different textures
Limitations
- Dust generation requires enclosed booths and extraction systems
- Surface roughness variation depends on operator skill and media consistency
