System and method for high-volume production of artillery shell casings using giga-casting

A method for producing artillery shell casings, comprising:

• moving a movable platen of a giga-casting press toward a fixed platen to close first and second die components and define a die cavity shaped to form a plurality of artillery shell casings;
• applying, with the giga-casting press, a clamping force that maintains the first and second die components in the closed condition;
• delivering molten metal to an injection channel fluidly connected to the die cavity;
• while maintaining the clamping force, advancing a piston in the injection channel to inject the molten metal into the die cavity under high pressure to form the plurality of artillery shell casings;
• cooling the molten metal in the die cavity to solidify the plurality of artillery shell casings;
• reducing the clamping force and moving the movable platen away from the fixed platen to open the first and second die components;
• and
• ejecting the plurality of artillery shell casings from at least one of the first and second die components.
