Abstract:
Methods and systems are provided for continuously producing cast metal components. An exemplary method includes feeding molten metal into a first mold at a fill station; maintaining a pressurized chamber at an elevated pressure; moving the first mold into the pressurized chamber, wherein the molten metal solidifies in the first mold under the elevated pressure; and removing the first mold from the pressurized chamber.
