Product Details

Blasting Glass Beads

Glass bead blasting produces a clean, bright, without dimensional change of the parts. Available in a wide range of sizes。

glass beads are primarily used in blasting cabinets for polishing, peening, blending, finishing, removing light burrs and cleaning most light foreign matter.

For delicate thinwalled parts and thin welds, peening with glass bead abrasive material provides the right balance of stress relief without overstressing and causing damage.

Consider the size of perforations or holes through which the glass beads must pass when screen separating parts from media after use. Glass beads are manufactured from lead-free, soda lime type glass, containing no free silica that is made into preformed ball shapes.

Finishing:

Glass Beads are used on metal, glass, rubber, and plastic to create a uniform, smooth or shiny finish.

Cleaning:

Glass Bead Blasting removes substances from surfaces without changing the surface dimension.

Deburring:

Glass Beads effectively remove burrs, including in precision operations.

Peening:

Glass Beads are effective in Peening operations to combat stress cracks and fatigue, even with thin welds and parts.

Grinding Glass Beads

Glass beads with the quality of clean,transparent,no bubbles and impurity. Its hardness and spherical form is suitable to remove impurity and metal oxides with no damaging of the treated surface. It also does not react chemically with other materials so that it widely used in blasting, polishing, grinding, Kaolin delaminating, etc
