Process and apparatus for forming plastics by heating an open mold and contacting the open mold with plastic particulate material to form a melted skin on the mold, and resulting articles made therefrom. Single skin molded articles may be multi-layered with or without paint on the surface. Multiple skin molded articles may be made by complementary male and female molds, brought together after the skins are made on the individual male and female molds, and may include sandwiched layers of plastic filler or expandable foam filled centers, with or without various inserts or reinforcements. Multi-layer composite articles are made with inserts and/or reinforcements that may be embedded in and surrounded by expandable foam plastic, if used as a middle layer. Resulting articles include a pick-up truck bed box, an industrial tabletop, a series of modular housing panels, an airplane cockpit door, and material handling pallets, among others.

Process for forming plastic, apparatuses for forming plastic, and articles made therefrom

A process for manufacturing an article ( ) by forming different portions of the article from different materials including using filler materials that are incorporated into a molten resin prior to forming the article. The selection of the resin and the filler materials impart differing properties to the article in the location where the materials were directed. The filler materials may include ceramic powders, clays, polymeric resins selected for their material properties, recycled materials, whisker materials and the like. The article may be subjected to an adhesion fluid, such as a gas or liquid, after formation in order to adhere all filler particles to the surrounding resin. If the adhesion treatment is acidic in nature, an optional step of neutralizing the article with hydroxides, carbonates or the like may be useful. An article ( ) made by the process includes multiple materials located in various positions ( ) around the article especially useful to have portions that may be electrically, thermally, magnetically conductive or insulative, or the properties may need to include surface texture, catalytic surface inclusions, or adhesion properties.
