Abstract
A hybrid casting process for structural components uses a re-usable metallic mold rather than a sand mold to produce more consistent cast components. The hybrid casting process uses a metallic mold coupled to a core mold to produce the near net shape of the cast component. Machining operations are performed on the near net shape cast component to produce a final component that meets tolerances and other specifications of the structural component.
