Abstract

PURPOSE:To enable the production of a molded article with a clear pattern by feeding colored pellets of various colors intermittently or continuously from holes for a small hopper arranged in a decompression portion of the screw of a waste-plastic reuse extruder. CONSTITUTION:A proper amount of a filler is admixed to pulverized waste plastics to even physical properties and strength, and the mixture is plasticized by an extruder and molded. In this case, a screw 4 fitted in a heating cylinder 3 of an extruder 1 is formed with a small-diametered screw bottom portion 4', the portions around which is used as a decompression portion. The side wall of the cylinder 3 at the decompression portion is formed with an upward hole 5, to which is connected a small hopper 7 for feeding colored pellets of various colors from a rocket 11 through staggered holes 8, and colored pellets of arbitray shape and color are fed to the decompression portion intermittently or continuously. Thus fed pellets are heated to be softened, kneaded, plasticized, and injection molded from a nozzle to obtain a waste-plastic molded article with a sharp colored pattern.
