Starbead® Industrial Beads

Description

Starbead® 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
