Abstract: An apparatus for slip casting includes a pouring pipe for supplying slip, to which each mold is connected by way of a pouring hose having a pouring valve. A slip discharge pipe is provided in the vicinity of the pouring pipe. The pouring pipe and the slip discharge pipe are connected by a by-pass pipe which includes a rising pipe, a traverse pipe, a connecting pipe and an atmosphere pipe. Slip is fed from the pouring pipe to each mold. After a body is formed with a predetermined thickness in each mold 1, pressurized air is fed to the slip discharge spaces to discharge surplus slip to the slip discharge pipe. The height of the rising pipe is set so that the pressure of discharging the surplus slip and the head pressure of the slip within the rising pipe balance each other when the surplus slip is discharged to the slip discharge pipe. This allows the pressure within the slip discharge spaces to be stabilized.

Abstract: A shaped article such as a sanitary pottery product is formed through a pressure slip casting process. A mold having a molding cavity defined therein and a slip inlet/outlet hole communicating with the molding cavity is positioned on the support surface of a mold table while the mold table is being maintained horizontally. Then, the mold table is tilted through a first angle with respect to a horizontal plane so that an inner end of the slip inlet/outlet hole is positioned near a lowermost end of the molding cavity in the mold. Thereafter, a slip is introduced under pressure into the molding cavity through the slip inlet/outlet hole. After the clay of the introduced slip is deposited to a desired thickness, the excess slip is discharged from the molding cavity through the slip inlet/outlet hole.
