  • METHOD FOR MANUFACTURING FOAMABLE INJECTION MOLDING AND INJECTION DEVICE THEREFOR
    Publication number: 20190077059
    Abstract: An injection apparatus including a plasticizing unit (2) that plasticizes a raw material resin and an injection unit (3) that injects a plasticized molten resin. The plasticizing unit includes a heating cylinder (20) having a foaming gas injection valve and a screw (21) provided inside the heating cylinder. The rotation and advance and retreat movements of the screw are controlled such that a raw material resin is plasticized by the screw and a foaming gas injected from a foaming gas injection valve is dissolved in the plasticized molten resin. After the screw retreats to a prescribed position according as the molten resin accumulates in the front end side of the heating cylinder by the screw that is rotating, the screw advances with rotating to cause the molten resin which has been accumulated in the front end side of the heating cylinder to be transferred to the injection unit.
