PURPOSE: A compounding machine with a dual mixing structure is provided to promote the quality of a mold by uniformly distributing resins and additives even though a ratio of the additive is high. CONSTITUTION: A compounding machine includes a hopper for injecting resins, a heating unit for melting resins and a mixing unit. A screw(10) of the compounding machine comprised of a driving motor and a screw for extruding resins has a dual structure with an upper screw and a lower screw. An orifice notch(13) of a resin discharge unit of the upper screw is formed to control the discharge amount of the resin. A penetration hole is formed on an axis of the screw to form a cooling unit.
