Glass beads used in sandblasting are a kind of abrasive with unique characteristics widely used in processes such as cleaning or metal surface strengthening treatment. During manufacturing, cullet glass must be melted into a spherical shape and then annealed to eliminate internal stress and prevent damage. This transparent, clear spherical structure will not allow particles to embed, contaminate or otherwise damage the workpiece during use. Using different sizes of abrasives and different operating parameters, the glass beads will achieve different ...
