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

摘要

An extrusion-molding device is provided with: a channel for conveying a pasty starting material composition; screws for mixing the starting material composition and conveying the same downstream, the screws being provided upstream from the channel; a die from which a molded body formed from the starting material composition is extruded, the die being provided downstream from the channel; a resistance tube for connecting the channel and the die; and a rectifying plate provided between the screws and the die. The rectifying plate has a plurality of through-holes that pass therethrough from the upstream surface to the downstream surface, and the area of the opening of the through-holes on the upstream surface are greater than that of the through-holes on the downstream surface.
