Abstract
A method and apparatus for manufacturing an injection-molded article having an outer film on an exposed surface. The method includes securing the film about its periphery within a mold cavity prior to injection of molten material into the cavity. One way of securing the film is by applying vacuum pressure through peripheral holes in a frame surrounding the mold cavity. Molten material is injected into the cavity, behind the film and the film slips from its initial position to be forced against a wall of the cavity by molten material being injected into the cavity. The apparatus includes a frame for a molding apparatus, adapted to initially secure the film in place prior to movement of the core block into place and to permit the film to slip from its initial position to be forced against the cavity wall as molten material fills the cavity.
