ABSTRACT:
A pressurized slurry casting machine is provided which includes a feed tank with an agitator, a vertical conduit extending from the feed tank to a mold. The machine operates by creating pressure in the feed tank with the agitator propeller whereby the ceramic slurry will be forced to move up the straight conduit into the mold so as to be formed into the desired article. The respective connections of the conduit to the mold and the feed tank are each air-tight connections such that no air bubble-like contamination will result in the finished ceramic product. There is also provided a vacuum system capable of producing a negative pressure in the feed tank.
