Abstract

PURPOSE:To mold composite resin of superior mechanism strength by providing a deaeration opening just in front of a melting and plasticizing zone when the composite resin is directly mixed injection molded without melting and mixing beforehand. CONSTITUTION:A deaeration opening E is provided in a position where a material fed from a feeder B into a hopper C is preheated in a cylinder feed section D. The water content adhered to the material and a filling material is evaporated and removed, and deterioration generated by hydrolysis of resin is prevented without having powerful shearing action in the following melting and plasticizing zone F. The material is only heated and not melted during the process up to the deaeration opening E, and in order to prevent the material from overflowing out of the deaeration opening, the material fed to a molding machine is so adjusted that a feed section D is in a starving state by a feeder B operated with a screw A of the molding machine. Also, the deaeration opening releases backflowing air properly to stabilize material feeding and not to fly and disperse a fine powder material.
