not actually sand or a silica. Silicon dioxide dust found in
silica sand has been linked to a respiratory disease known as
silicosis and is considered an environmental toxin.
Instead, we use an exclusive combinations of glass beads
and aluminum oxide to deliver a fast and efficient cutting
action while maintaining close tolerances resulting in a fine
satin finish.
We also use some exotic medias, everything from walnut
shells to corn cobs and plastics.
Plastics are relativity new and are a dust free media use for
de flashing plastic parts and cleaning molds, dies, electronic
connections and circuit boards. It can effectively de burr
machined-iron castings and non-ferrous machine parts.
Plastic will not warp thin metals because it does not bite into
the substrate causing the metal to stretch and distort.
and mounting. The Bigelow Sandblasting and Painting Co. has
"state of the art" blast cabinets for smaller items as well as
blast rooms for larger projects such as automobiles. The
blasting machines prepare the surfaces by directing a stream of
abrasive particles against a part or a surface. Blasting is used
for:
- Cleaning precision parts such as small gears;
stampings, forgings and extruding dies; molds for glass,
plastic, rubber, and metal castings; pistons, valves,
cylinder heads; windings, armatures, brushes and rotors
in the overhaul of electric motors and generators;
machine parts, etc. - Removing heat treat scale; carbon deposits; slag,
oxides and discolorations; scale from high speed drills
and other cutting tools; light machining burrs; paint,
varnish and lacquer, etc. - Preparing surfaces for painting, plating, anodizing,
welding and bonding of coatings - Reclaiming rusted tools; used files; saw blades;
hardware parts. - Finishing to provide decorative quality finish for the
- automotive, appliance, photographic and to improve
appearance of castings by removal of scale and thin
edges, and blending of minor defects; dimpling surfaces
to improve adhesion for plastic, rubber and paint.
- Auto and truck restoration has become a booming
- industry. Whether you are a D.I.Y. enthusiast, paint and
body technician or body shop owner, having access to
"quality" blasting companies is a necessity.
- The following list will illustrate the advantages of abrasive
blasting instead of hand sanding:
- Time and labor savings
- Removal of pits and rust spots
- Cleaning of engine parts
- Accessing hard to reach areas
- Removal of road grime and gunk from the
undercarriage
- Boats:
- Regardless of how much fun a boat is, keeping it in great
shape requires many hours of maintenance and care.
Abrasive blasting a boat is an effective way to strip the
paint off of the hull in order to prepare the body for
refinishing. More traditional and time-consuming methods
for boat stripping include chemicals, acids and a lot of
scraping which can result in environmental damage.
equipment that are enclosures in which
items are placed to be abraded. Blast
cabinets are useful in containing the
blasting operation and preventing
exposure of the blasting media to
surrounding workers. The media

which large items may be blasted. Like
blast cabinets, blast rooms keep the
blasting operation contained, thereby
limiting exposure of abrasives to
workers and the enviroment. The
media re-claimers are also use in the
blast rooms.
