A die casting machine is provided that includes a controller, a casting mold, and a material injection system. A method for operating the die casting machine is provided that includes detecting a downtime event using a controller, determining a length of time between a beginning of the downtime event and an end of the downtime event, determining a number of preheat castings to produce in a preheat cycle, and transmitting a signal instructing the casting mold and the material injection system to produce the number of preheat castings.

The present application relates to a low-pressure casting multi-sprue process and device for an aluminum alloy wheel. A multi-sprue casting method is adopted, and a plurality of sprues are arranged at the end of the inner flange of a wheel, so that molten aluminum enters at the inner flange first, then enters from a center sprue after a mold cavity at the rim is full of the molten aluminum. The mold assembly is pressurized and cooled after the mold cavity is full of the molten aluminum. During cooling, starting from the outer flange of the wheel filled with the molten aluminum last, side mold ring water coolers are started.
