    Abstract: The present invention relates to light weight molded plastic articles and methods of making same. More specifically, the present invention relates to a method of manufacturing a hollow-core, foamed-plastic, film-laminate article utilizing convention gas assisted molding apparatus with corresponding high production rate capabilities. The resulting film-laminate, hollow-core, foamed-plastic part comprises a class A show-face surface. The method comprises formation of a porous mass of molten plastic in the mold cavity containing the laminate. The molten plastic is cored out or hollowed by injection of gas into the mold cavity.

    Abstract: An improved molding apparatus and method of use thereof that inhibits unsightly blemishes that may be formed in molded plastic parts in caused by confined crevices of the molding apparatus. A mold cavity is formed by at least two mold portions and one of said mold portions has a molten plastic flow diverter positioned adjacent the confined crevice. The charge of molten plastic is injected into said cavity such that a portion of the charge of plastic flows over the diverter and into the confined crevice of the mold cavity. The diverter creates a narrow restriction adjacent the crevice such that the mold cavity has a larger cross-sectional area on either side of the diverter.

    Abstract: A method and apparatus for laser trimming a shaped plastic workpiece use a laser beam positioned and directed by a robotic arm traveling along a pre-programmed path to trim the edges of a workpiece held against a positioning block. Preferably, the positioning block includes a laser beam capturing channel comprising suction holes for removing smoke generated by the ablation and burning of the plastic so as to minimize the risk of smoke damage to the workpiece and to remove soot and vapors from the work area. At the same time, laser beams are inhibited form reflecting back off the block onto the workpiece by positioning the channel under the workpiece and along the predetermined cutting path.
