Media Blasting

Media Blasting is offered at ProtoSpace as a standard finish within our fast 2–3-day leadtime.

Your part is deburred and cleaned, then sprayed with a steady stream of tiny glass beads via compressed air. The end result is a smooth, bright finish that’s flat and non directional.

Media Blasting is excellent for machined parts, and can be done on sheet metal parts. Large, thin sheet metal should be avoided in order to avoid warpage.
