Media blasting 101
(Click Question for Answer)



What is media blasting?
Media Blasting is the process of smoothing and stripping rust, paint and other applications from a hard surface by forcing solid particles across the surface at high speeds, using compressed air.

What kind of surfaces can be media blasted?
Metal, plastic, wood, glass, stainless steel, brick and concrete can all be media blasted.

Why is it sometimes called sandblasting?
The process used to involve sand, but it no longer does due to the health risks of inhaling silica articles.

What do you use now, instead of sand?
Media blasting today uses many materials including:
  • Garnet: A hard, durable, low-dusting natural mineral abrasive which is capable of achieving high coverage rates. Coarser grades may be recycled a number of times. Typical applications include blasting of stainless steel and special alloys. Using garnet is very popular with our clients and we excel in its use.

  • Glass beads: Modern metalworking demands efficiency, quality, and reproducible results. Impact technology using Potters' glass bead media that delivers cost effective, precise control for peening, cleaning, finishing, and deburring processes. Glass beads can be used in a variety of industries, including aerospace, automotive, food service, and electronics.

  • Plastic: Plastic abrasives deliver a high stripping rate and consistent performance which is ideal for paint stripping, mold cleaning, deflashing and deburring. Since the plastic abrasive is harder than the coatings to be removed, yet softer than the substrate, coatings can actually be stripped three or four times without damage to the surface.

  • Aluminum oxide: Harder than other commonly used blasting materials, aluminum oxide grit powder penetrates and cuts even the hardest metals and sintered carbide. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower cutting media. Aluminum oxide grit media has a wide variety of applications, from cleaning engine heads, valves, pistons and turbine blades in the aircraft industry to lettering in monument and marker inscriptions. Media is a good choice for an abrasive sand blasting and polishing grain, as well as for preparing a surface for painting.
