<P>PROBLEM TO BE SOLVED: To provide an extrusion-molding apparatus capable of achieving more stabilization of a shape of an extrusion-molded body by making a velocity of a ceramic material in a resistance pipe uniform, and coping with molding the molded bodies of various shapes without a change of the shape of the resistance pipe. <P>SOLUTION: The extrusion-molding apparatus 1 includes a molding die 3 attached to a tip end of an approximately annular pipe-like barrel 13 via the resistance pipe 14, and a screw 12 kneading the ceramic material 4 supplied from the base end of the barrel 13 in the barrel 13 and force-feeding it to the molding die 3, and extrudes the ceramic material 4 from the molding die 3 and shapes the ceramic molded body 42 wherein the inner diameter of the resistance pipe 14 is constant. <P>COPYRIGHT: (C)2008,JPO&INPIT |
