    摘要: A foaming molten resin containing reinforcement fibers and super critical fluid is injected into a cavity with a short shot (a), the foaming molten resin is made self-foam and flow in the cavity (b), and a volume of the cavity is increased by expanding molds so as to expand the foaming molten resin in the cavity (c). During the expansion step (c), the expansion of the foaming molten resin is assisted by gas vent, vacuum suction, partial pressure adding with gas or resin, or a spring back force of the reinforcement fiber in the foaming molten resin. Accordingly, there can be provided a resin foam molded article that has no improperly large air voids therein, a sufficient volume expansion thereof, and a superior transferability function.

    摘要: 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.
