Sandblasting propels abrasives at the part via a high-pressure air stream. It can abrade into the minutest details and produce a very even finish. Sandblasting removes small burrs but not heavy burrs (burrs which are too thick to bend or break off using a fingernail or pencil). Use sandblasting for light deburring or scale removal and to provide an even finish for painting or plating. Glass bead is a round abrasive media that is reusable and will product a satin finish. It is designed for cleaning, peening, and cosmetic finishing where stock removal must be minimized. A wide range of sizes allows smooth to more textured finishes and are excellent for ferrous and non ferrous surfaces
