  • Patent number: 8919422
    Abstract: A die casting system includes a die, a shot tube, a melting system and a vacuum system. The die includes a plurality of die components that define a die cavity. The shot tube is in fluid communication with the die cavity and is operable to deliver a charge of material to the die cavity. The melting system is positioned adjacent to the die and includes an alloy loader, a melting unit and a crucible. The vacuum system defines a first chamber and a second chamber separated from the first chamber by an isolation valve. The melting system is disposed within the first chamber, and the die is disposed within the second chamber.
