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 discoloration
• 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.

Our Glassbeads can be certified to meet most of today’s standard specifications including Military, Aerospace and Automotive specifications.
