  • Patent number: 5648030
    Abstract: A method for achieving high definition graphics in the surface of a body molded from plastic powders. The method is specifically described for use in achieving high definition graphics in the surfaces of kayaks formed by rotational molding using plastic powders, with the kayak mold being heated to above the transition temperature of the plastic powders. The high definition graphics are achieved by preplacing a stencil containing cut-outs for the desired design against the surface of the kayak body mold. The openings of the stencil are filled with a plastic powder corresponding to the color(s) of the design. After removal of the stencil, an overlayer of plastic powder corresponding to the main kayak hull is applied. Local heating is achieved to form a skin on the combination of these pre-placed powders. Subsequent heating of the entire mold in a heated oven, with appropriate rotation of the mold, distributes the bulk powder for the hull, melts the powders, and forms the entire hull.
