  • Patent number: 6663822
    Abstract: A process for manufacturing an article (10) 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.
