PURPOSE: A balance injection molding machine by mixing iron powder with plastic compound is provided to improve the quality of the product, and to cut down manufacturing cost by putting, extruding, mixing, transferring and injection-molding raw material and iron powder successively. CONSTITUTION: A nozzle(1-2) is formed in the end of an injection molding plunger body(1), and a mold(3) is installed in front of the nozzle. A hydraulic cylinder or injection sub motor(2) is installed in the rear part and connected to a plunger piston rod. A heater(4-4) is attached to the vertical wall of an inlet, and a screw of a mixing and transferring cylinder is turned by a low speed motor(5). An input port(6-3) of the mixing and transferring cylinder is connected to transfer pipes connected to a plastic extrusion cylinder(6) and an iron powder hopper(9) with a heater(9-3). The plastic extrusion cylinder is horizontally mounted, a hydraulic cylinder(7) is mounted in the screw rod of the plastic extrusion cylinder. A supply amount regulating unit is formed in a plastic raw material hopper(8).
