  • Method and apparatus for manufacturing chips for a thixomolding-process injection molding machine
    Patent number: 6186424
    Abstract: In a method and an apparatus for manufacturing chips for a thixomolding-process injection molding machine, primary crushed pieces obtained by fragmenting and crushing metal alloy wastes are cut and fragmented by a chip manufacturing apparatus having fixed blades, rotating blades, and a screen so as to obtain chips, with the result that the surfaces are polished, and a powder is eliminated by forced exhaust air, thereby making it possible to manufacture the chips while preventing ignition and explosion.
