What are the difference btw sandblasting and beadblasting?
The difference between the two are basically the media & as a result
the type of finish produced.
Sand blasting is a system of using clean, sharp sand or other media
like garnet, silicon carbide, aluminum oxide etc. propelled by a
high pressure air stream. The stream of air & media is directed at a
surface to abrade it for cleaning or to texture it. Typically, if
the finish is important, the media used is graded by grit size to
give the desired finish.
Bead blasting typically uses glass beads instead of the other media.
It is also graded by size.
The big difference between the two types of media is one of hardness
& grain shape. The glass media is lighter, softer, rounder & has
fewer sharp edges. For a given air pressure, it leaves less of an
impression on the surface being blasted.
Both types of media can use the same basic machinery for
