  • Patent number: 11007687
    Abstract: A system and method to dispense, mix, and inject liquids and force them into a vented investment pattern mold cavity comprises a source of raw materials in fluid communication with an injection unit for metering and delivering the raw materials. A mixing and injection head receives and mixes the metered raw materials. A movable molding cart upon which an investment pattern mold is mounted is disposed adjacent the injection unit and proximate the mixing and injection head. The movable molding cart includes a fill cup that may be engaged by the mixing and injection head. A displaceable gating tray provides fluid communication with the fill cup and a sprue aligned with an investment port on a lower portion of the investment pattern mold. The system also includes a digital computer control by which the injection process may be controlled.
