ABSTRACT:
A method of drying a sand mold mixture containing moisture includes restraining the sand mold mixture and exposing the sand mold mixture to a vacuum. The vacuum flashes off the moisture within the sand mold mixture thereby drying the sand mold mixture to create a solidified sand mold. The restraining member prevents voids from forming in the sand mold during exposure to the vacuum.
