    摘要: The present invention is a thermoplastic panel or piece having a resilient injection molded portion. The panel or piece of the present invention may be used in a variety of applications such as to provide sealing ends on thermoplastic panels or to create resiliently closable passages in thermoplastic panels through which wires and other objects may be passed while maintaining an even surface appearance of the baseboard panel. Other uses include attaching one or more thermoplastic pieces together. The invention also includes a method for making the subject thermoplastic panel or piece.

    摘要: The present invention relates to a system and a method for cooling extruded and molded materials. The present invention is especially useful to thoroughly cool an extrudate by directing a cooling fluid toward a surface of the extrudate (e.g., an interior surface that defines a hollow portion of an extrudate). Hollows may be created in order to reduce material, weight, and/or processing time. A cooling fluid is diverted toward the surface of the extrudate so as to cool the material and assist in solidification. A baffle may serve to divert the cooling fluid in the desired direction. In another example, the extrudate may be partially or totally immersed in a liquid cryogenic fluid. Increases in production line throughput may result by rapidly cooling the molded material. In addition, the more efficient cooling may be achieved with a lesser amount of the cooling fluid, and the velocity and temperature of the cooling fluid may be reduced. Other uses for the present invention include injection molding, compression molding, gas assist molding, and co-extrusion.
