  • Methods of selecting thermoplastic materials for use with plastic article forming apparatuses that control melt flow
    Patent number: 11010816
    Abstract: A method of selecting thermoplastic materials for use with an injection molding apparatus that adjusts viscosity of a thermoplastic material based on an interpreted viscosity is provided. The method includes determining a target MFI for an identified plastic article based on performance properties. A thermoplastic material supply chain is analyzed and a first thermoplastic material having a first starting MFI and a first MFI range is identified and a second thermoplastic material having a second starting MFI and a second MFI range that is greater than the first MFI range is identified and is priced less than the first thermoplastic material. The second thermoplastic material is purchased. The second thermoplastic material is tested by providing the second thermoplastic material to the injection molding apparatus for multiple shot molding cycles with the second thermoplastic material in a molten state.
    Type: Grant

  • Injection mold with fail safe pressure mechanism
    Patent number: 9604398
    Abstract: A low pressure injection mold includes a failsafe pressure mechanism that prevents the low pressure injection mold from being subjected to excessive injection pressures or excessive clamping tonnage that could damage the low pressure injection mold.
