Abstract
Methods of manufacturing castings are described. The method can include heating a ceramic mold comprising a gate inlet, and melting a metallic composition. The method can also include presenting the ceramic mold to a casting station such that the gate inlet is in fluid communication with the molten metallic composition, and casting against gravity the molten metallic composition into the heated mold through the gate inlet. Furthermore, the method can include rotating the mold to position with the gate inlet in an upward direction while the metallic composition is at least partially molten within the mold, and quenching the molten metallic composition in a liquid quench medium to solidify the molten metallic composition within the mold.
