Title:
EXTRUSION-MOLDING DEVICE AND METHOD FOR PRODUCING MOLDED BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/158915
Kind Code:
A1
Abstract:
An extrusion-molding device is provided with: a channel for conveying a pasty starting material composition, the cross section of the channel being substantially circular; 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 flow volume adjustment plate provided with a plurality of openings that pass therethrough in the thickness direction, the plate being provided between the screws and the die. The ratio (L/D) of the length (L) of the distance between the flow volume adjustment plate and the die to the diameter (D) of the channel is 0.5-5 inclusive, and the flow volume adjustment plate makes the flow velocity distribution of the starting material composition uniform before the starting material composition enters the die.
