Glass Bead

Glass bead blasting media is formulated from chemically inert soda-lime glass and is spherical in shape.

Common applications include:

  • Removal of carbon deposits
  • Removing heat treatment scale and weld discolorationblasting media
  • Mold cleaning
  • Finishing of food preparation and medical equipment
  • Deburring cast, machined and stamped parts
  • Peening aerospace and automotive parts.

 

In many cleaning & finishing applications, glass bead blasting can replace a multi-step process with a single, efficient, and economical one-step process.

 

Glass bead performance benefits

  • Rapid results: Clean, finish, peen and deburr in one step.
  • Controlled results: Clean finish w/o significant metal removal or changing tolerances.
  • Versatile: Create a wide range of reproducible surface finishes.
  • Economical: Can be recycled/reused many times.
  • Chemically inert: No ferrous or other residues.
