We are now engaged in the study on a resin flow control molding method in which molecules and fillers are positively oriented by displacing resin flows in the mold. We intend to confirm that the resin flow control molding method can properly control the orientation of fibers in glass fiber reinforced polypropylene moldings. We have also attempted to improve physical properties of poly-lactic acid molded by the resin flow control molding method. We have directly observed the process of filling resins into a glass-inserted mold to prove effectiveness of the resin flow control molding method.
