  • System and process for molding polymeric articles while reducing gate blush
    Patent number: 11230042
    Abstract: A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a runner that extends from an injection point to a gate. The gate is positioned adjacent to an opening leading into a mold cavity. In accordance with the present disclosure, the system includes one or more overflow passages that divert flow of the polymer composition so as to temporarily reduce the flow rate and pressure of the polymer composition entering the mold.
    Type: Grant

  • Apparatus and method for in-mold coating an article by injecting an in-mold coating through the article
    Publication number: 20050156351
    Abstract: A molding apparatus and method is provided that allows an in-mold coating to be injected from one side of a molded article onto another show side of the molded article. A first composition injector injects a thermoplastic composition into a molding cavity of a mold to form the molded article. A second composition injector injects an in-mold coating composition into the one side of the molded article, through the molded article and onto the show side of the molded article.
