Abstract
A method of slip casting wherein reduced pressure is applied to the mold during casting by virtue of a network of piping extending through the mold. The mold has an impermeable outer coating. Heat may also be applied to the mold during casting, by for example a heated fluid passing through piping located in the walls of the mold.
Claims17
A mold usable in reduced pressure slip casting, wherein the mold is made of plastics material and comprises a plurality of parts sealingly connectable together to provide a closed permeable mold with an impermeable coating provided on the outside of the mold, said mold comprising a heating pipe extending substantially throughout the walls of the mold, wherein the heating pipe is connected to a source of heated fluid, said mold also comprising means for supplying reduced pressure within the walls of said mold, said reduced pressure supply means comprising a network of tubing separate from the heating pipe extending within the walls and connectable to a source of reduced pressure.
