Sandblasted glass beads are a unique abrasive widely used in cleaning or metal surface strengthening processes, mainly in sandblasting equipment.
Glass beads are crushed and sorted from high-quality cullet. During manufacture, cullet is melted into spherical shape and then annealed to relieve internal stress and prevent breakage. This transparent, clear spherical structure product will not have particles embedded in the workpiece during use, contaminating the workpiece or causing other damage. Using different sizes of abrasive and different operating parameters will result in different gloss levels on the workpiece surface. The use of shot peening glass beads on the workpiece surface for selective local coverage and controlled sandblasting can produce special decorative effects.

The excellent properties of glass beads make it very suitable for selection without damaging the workpiece surface when cleaning or deburring workpieces with strict requirements on deviation. Furthermore, the inherent strength makes it suitable for use in equipment that can recycle abrasives.
Glass beads are also widely used to treat the surface of workpieces with residual tension or periodic pressure to generate a compressive stress layer to achieve the purpose of surface strengthening. Strengthening the workpiece surface with glass beads reduces potential hazards such as surface erosion or surface fatigue.
