EXTRUSION-MOLDING DEVICE AND METHOD FOR PRODUCING MOLDED ARTICLE USING SAME

摘要

This extrusion-molding device is provided with: a channel for conveying a starting-material composition in the form of a paste; a screw for mixing the starting-material composition and conveying the same downstream, and positioned on the upstream-side of the channel; a die from which a molded article comprising the starting-material composition is extruded, and positioned on the downstream-side of the channel; a rectifier having a plurality of openings penetrating in the thickness direction thereof, and positioned between the screw and the die; a resistance tube for connecting the downstream-side of the rectifier and the die; a plurality of resistance pins which each have individually adjustable lengths projecting into the inside of the resistance tube, and positioned so as to penetrate the tube wall of the resistance tube; and a means for adjusting the temperature of the plurality of resistance pins.
