Applications:
Used as a surface pre-treatment for subsequent coatings (paint, powder, anodizing), or as a final surface aesthetic for a matte/frosted finish on metal surfaces. Also used for removing scale, oxides, burrs, old coatings.
Advantages:
Efficient removal of surface contaminants, burrs, oxides, providing a clean, uniform surface and improving adhesion of subsequent coatings.
Can impart a controlled texture to the surface (matte, frosted) for aesthetic or functional effect.
Appearance:
Uniform matte or frosted texture; directional or non-directional depending on blasting media and process.
Applicable Materials:
Aluminium, steel, stainless steel, brass, copper, titanium and many other alloys.
Important Notes:
Process must be controlled: media type, pressure, angle, distance will determine surface roughness and potential damage (over-blasting can fatigue or distort thin sections).
After blasting, proper cleaning is required (blasting media, dust removed) before further finishing.
Surface roughness must be matched to the intended subsequent coating—too rough may impede fine finishing; too fine may impair adhesion of coatings.
Some substrates (e.g., thin-walled parts) may require special fixturing to avoid distortion under blasting pressures.
