  • Optimized tooling design for vertical die casting machines
    Patent number: 7516773
    Abstract: An apparatus and method are provided that increase yield and reduce cycle time. In particular, a gate plate for a die casting machine is configured to lessen the waste produced during die casting, resulting in greater yield. Further, the gate plate is configured with tapered sides to produce a draft, leading to less friction during the gate break/pull back sequence. This draft reduces the amount of unpressurized dwell time and subsequently the cycle time for producing the cast part.
