There are provided a plasticizing-kneading step of plasticizing a reinforcement fiber and a resin in a cylinder having a screw, and a metering-injecting step of supplying a physical foaming agent to the resin and injecting them into a cavity of a mold, after metering the necessary amount of resin for molding, a foaming-agent supplying step of supplying the physical foaming agent to the resin passed through a nozzle after being plasticized, and a mixing-dispersion promoting step of promoting mixing and dispersion of the physical foaming agent in the resin in a resin flow path from a supply portion of the physical foaming agent to the cavity of the mold. Accordingly, any breakage of reinforcement fiber is prevented and the mixing and dispersion of the physical foaming agent is improved.
A molding method of a fiber filler reinforced resin molded article, which includes a plasticizing-kneading step of plasticizing and kneading a reinforcement fiber and a resin in a material supply cylinder having a screw, and a metering-injecting step of supplying a physical foaming agent to the resin plasticized in the plasticizing-kneading step and injecting the resin into a cavity of a mold, after metering a necessary amount of the resin for molding, the molding method comprising:
A molding apparatus of a fiber filler reinforced resin molded article, which includes a mold having a cavity that a resin is injected therein, a plasticizing-kneading portion operative to plasticize and knead a reinforcement fiber and the resin in a material supply cylinder having a screw, and a metering-injecting portion operative to supply a physical foaming agent to the resin plasticized in the plasticizing-kneading portion and inject the resin into the cavity of the mold, after metering an necessary amount of the resin for molding, the molding apparatus comprising:
