METHOD FOR MANUFACTURING CERAMIC INLET

WIPO Patent Application WO/2012/138027

A1

The present invention relates to a method for manufacturing a ceramic inlet and is characterized by comprising: a step for preparing a plaster frame, by preparing a plaster frame having an internal space corresponding to the external shape of the ceramic inlet which is in an up / down flipped-over state, and having a jaw portion protruding and extending from the upper portion of the floor of the internal space, and spaced apart by a length corresponding to the transverse thickness of the ceramic inlet from the side walls; a step for injecting plasticized clay, by injecting plasticized clay having sufficient viscosity to form a shape within the internal space of the plaster frame; a step for making an intermediate cast inlet, by making an intermediate cast inlet using a molding machine equipped with a head which simultaneously rotates and moves up-ward the injected plasticized clay within the plaster frame; a step for making drop, by dropping away the sides of the inlet from the floor portion of the plaster frame from the top of the jaw portion according to shrinkage in volume of the intermediate cast inlet as moisture contained therein is absorbed into the plaster frame; and a step for drying by drying the intermediate cast inlet which was dropped from the floor portion of the plaster frame in the step for making drop and separated from the plaster frame.
