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.
Claims15
A method for producing a structural component, the method comprising:
- aligning a core within a metallic mold by coupling the core to metallic locators attached to the metallic mold;
- filling the metallic mold with a molten metallic material;
- solidifying the metallic material within the metallic mold to produce a cast component;
- removing the cast component from the metallic mold;
- identifying a datum location, wherein the datum location is a central axis of an aperture extending through the cast component to the core;
- removing material from one or more of an internal surface and external surface of the cast component based off the datum location;
- heating a first portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- heating a second portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- cooling a third portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- and
- cooling a fourth portion of the metallic mold during the solidifying of the metallic material within the metallic mold.
