GLASS BEADS for sandblasting are spherical glass abrasive materials by melting and shaping recycled glass. 

The product itself is colorless and transparent but generally has a white appearance. 

   








Applicable industries:
Aviation industry; automobile industry; sandblasting/painting business; consumer goods manufacturing; foundry industry; subcontractor, semiconductor industry.

Applicable process range
Cleaning of integrated circuit block support; strengthening of aircraft engine turbine blades and other parts; decorative parts; surface treatment before electroplating or electrolytic spraying; cleaning or deburring of non-ferrous components, and cleaning of molten residues in high-temperature molds.


 Sandblasted glass beads:
•Sandblasted glass beads can be used to clean various molds such as punching, segment pressing, glass, rubber plastic, metal casting, and extrusion.
•Sandblasted glass beads can eliminate tensile stress, increase fatigue life and improve stress corrosion resistance. Such as: aircraft engine turbines, blades, shafts, landing gear, various springs, gear hydraulic parts, etc.
•Sandblasted glass beads can be used to clean up the circuit board and plastic seal before tinning on the tube and remove the waste edge burr.
•Sandblasting glass beads can remove blockages in pistons and cylinders. Provide a bright semi-matte surface for medical machine tools and auto parts.
•Sandblasting glass beads can clean motors, coils, brush rotors and other parts during overhaul.
•Sandblasted glass beads can be used to clean and deburr various metal pipes and non-ferrous metal precision castings. Shot peening and finishing of textile machinery parts.

The main application of shot peening glass beads:
  • Clean and matte treatment of metal surfaces

  • Surface cleaning of various molds and metal surface cleaning

  • Removal of edge thorns before tin on semiconductor devices and plastic encapsulation tubes

  • Remove burrs and residues on the surface of various hardware products

The glass beads supplied by our company have stable chemical composition, good color, high rounding rate, strong hardness and strength, regular and smooth particles, and few impurities. It can achieve a good effect of sandblasting and blasting, and can be used repeatedly.
