An investment casting process is provided in which a molten aluminum metal is cast into a refractory mold and thereafter cooled to solidify the metal in the mold. The improvement includes the step of cooling the mold and solidifying the metal therein which is carried out by placing the mold in a chamber adapted to retain a liquid. The mold is mounted in a stationary condition in the chamber. A coolant liquid is introduced into the chamber to immerse the mold in the liquid while maintaining the mold in a stationary condition.
