  • Structural article of relatively large dimensions
    Patent number: 6245415
    Abstract: Molding of relatively large articles such as automobile body parts by gas-assisted injection molding with sequential gating of injected thermoplastic resin into the mold cavity. Elongated ribs in the parts form gas channels and strengthening ribs for the parts. Structural parts are made by adhesively joining two such parts made by gas-assisted injection molding through a combination of hollow ribs and joining flanges at sides of the parts.
    Type: Grant
    Filed: September 10, 1999
    Date of Patent: June 12, 2001
