Shot Blasting Glass Beads

Star's are high quality glass micro spheres resulting from the specialised processing of selected glass cullet.

Application

· Cold working of metal surfaces, i.e. shotpeening and honing. 

· General cleaning, removing of light foreign matter. 

· Decorative finishing, polishing or matting.

Advantages

· Used for the cold working of metal surfaces as well as for general cleaning, deburring and decorative finishing whilst retaining the dimensional integrity of items being blasted (e.g. pistons).

· For delicate thin-walled parts and thin welds, peening with glass bead abrasive material provides the right balance of stress relief without over-stressing and causing damage.

· A silica-free option for shot blasting, peening, honing, cleaning and light deburring

· Chemically inert and environmentally friendly

· Available in a wide range of sizes

· Can be recycled up to 30 times
