Glass Beads

Glass Bead is a versatile air-blasting media used in a variety of applications:

  • Finishing:
    Glass Bead blasting can be used on a wide range of materials, including metal, glass, plastic and rubber. The smaller the glass spheres, the smoother the surface; larger spheres produce a more textured finish
  • Cleaning:
    Glass Bead blasting removes/cleans foreign substances from the surface without a dimensional change to the surface. A wide range of bead sizes is available
  • Deburring:
    Glass Bead blasting removes burrs and feathered edges from parts in a precision operation. Corners and edges must be deburred with precision in order to assemble and operate properly. Glass Bead blasting guarantees that no base metal from the surface is removed
  • Peening:
    Peening with Glass Bead is a low-cost form of creating a uniform surface layer of compressed stress in alloy substances. Peening acts to combat stress cracks and corrosion, resulting in increasing the life of metal parts. The high degree of roundness of our Glass Bead media enhances the performance of stress-resistance processes

Advantages of Glass Beads

  • Wide range of grades available for different jobs and profiles
  • Non-reactant; will not interfere with coatings
  • No dimensional change to the surface, and no embedded contaminants or residue left on material
  • Smoothly blends away surface defects and improves corrosion resistance
  • No detectable crystalline silica
