  • Low pressure injection molding of knife blades from metal feedstocks
    Patent number: 6315935
    Abstract: A process for molding metal knife blades from powders and molding compositions therefor are disclosed. Parts produced by this process are formed near net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing metal powders, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in an injection molding machine under conditions of temperature and pressure to produce a self-supporting knife blade having a sharp edge.
    Type: Grant

  • Low pressure injection molding of metal and ceramic powders using soft tooling
    Patent number: 6203734
    Abstract: A method for rapidly manufacturing soft tooling from organic polymer-based resins and reinforcement filler materials for use in an injection molding machine to make complex metal and ceramic parts from powders. The cost to produce the tooling is relatively low and the manufacturing time is relatively short compared to conventional processes for making metal tooling. The finished parts are near-net shape, requiring little or no machining, and have excellent sintered properties.
