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

摘要

The extrusion-molding device of the invention includes a flow passage for transporting a paste raw material composition; a screw provided at an upstream side of the flow passage to knead the raw material composition and transport it to a downstream side; a die provided at a downstream side of the flow passage to extrude a molded body composed of the raw material composition therefrom; a resistive tube for connecting the flow passage and the die; and a current plate provided between the screw and the die. The current plate comprises a plurality of through-holes that penetrate from a upstream end side to a downstream end side, and an opening of the through-hole on the upstream end side has a larger open area than an opening on the downstream end side.
