Abstract: A number of variations may include at least one mold portion that may define a first cavity, a circular gating system, and at least one sprue. The circular gating system may surround the first cavity and define a continuous in-gate from the circular gating to the first cavity. The at least one sprue and at least one vent may be in fluid communication with the circular gating system and the first cavity.

Abstract: A casting system includes a first mold, a second mold, the first mold and the second mold being configured to receive molten metal, the first mold and the second mold exerting pressure on the molten metal to form a mechanical component as the molten metal cools, and a sensor that measures the pressure exerted on the molten metal to provide feedback information to regulate the pressure exerted on the molten metal.

Abstract: A casting system includes a pour cup, a plurality of runners that receive molten metal from the pouring cup, a top mold and a bottom mold that receive the molten metal from the plurality of runners, and a plurality of slides positioned within the top mold and the bottom mold. The positioning of the plurality of slides applies direct pressure on the molten metal in the top mold and the bottom mold to form a cast structural component.
