glass beads for shot blast

Function: * The glass beads are used to spray into the workpiece surface to shot peening and polishing processing in High-speed and high pressure* Cleaning various moulds of forge,rubber, plastic, metal casting, extrusion etc.* Can eliminate tensile stress, increase fatigue life and improve the anti-stress and corrosion resistance. * For medical machine tools and automobile parts provide bright half matte surface.* Remove the piston, the cylinder's blocking.* Cleaning and removed waste burrs before tinning pipes.* Cleaning the motor’s rotor winding ,brush and other parts.* Cleaning and deburring. metal, non-ferrous metal and all kinds of precision casting * Textile machinery parts’ polishing processing and shot peeningDetails:Physical reference1. material: Composition Sio2>72%2. round percentage>80% 3. dia.
