  • Method of supplying a moldable mixture of materials to an article forming mold of an injection molding machine
    Patent number: 4728476
    Abstract: A method of supplying material to an article forming mold of an injection molding machine. The method comprises initially mixing a granular thermoplastic resin with a granular filler in a dry state and then heating the dry mixture in the chamber in which the feed screw of an injection molding machine rotates. The heating is controlled to initially convert the dry resin to a molten mass while simultaneously heating the filler with the filler remaining as a heated solid. After such initial heating the molten resin/heated filler is retained at a lower temperature prior to molding and then is further heated for ejection from the chamber.
