blasting glass bead

High strength glass beads ( blasting and peening ) It takes compressed air as the momentum and uses glass bead as the medium, through high-speed and high-pressure jetting on the surface of workspace.Products after shot blasting can eliminate the tensile stress, lengthen the fatigue life, and improve its capacity for anti-stress corrosion. These products have wide scope of application:◆ Clear diverse moulds of impact forging, forging, glass, rubber and plastic, metal casting and extrusion.◆ Eliminate tensile stress, increase fatigue life and enhance stress corrosion resistance. For example, aircraft engine turbo, vane, shaft, undercarriage, diversified springs and gears, etc.◆ Clean and remove slitter edge and burr on the circuit plate and plastic-sealed geminate transistors before stannum soldering◆ Remove stems in the piston and cylinder and provide bright and half-lackluster surface for medical mechanical instruments and automobile parts◆ Clear electromotor and such parts as loop, electric brush and rotor of during heavy repair◆ Clean up and remove burr of metal tube and precisely-melten non-ferrous metal tube. Be used for peening aggrandizement and polishing of textile machinery parts. )Advantages 　①The glass beads made of the soda-lime silica glass has the good chemical stability, certain mechanical intensity and hardness, so as polishing grind material compared to other grind materials has the very big superiority. 　②Cannot pollute the processing metal. 　③May accelerate the cleaning up, make the processing material to restore originally clean, smooth.
