PROBLEM TO BE SOLVED: To provide an injection molding machine for molding a product by providing an injection unit for plasticizing a resin at a fixed side and a movable side of the injection molding machine and by injecting the resin plasticized by improving the timing for injecting a plasticized resin into a cavity of a mold of these injection units. SOLUTION: In the injection molding machine provided with the injection unit 3 for plasticizing the resin arranged at the fixed side 1a of the injection molding machine and for molding a product by injecting the plasticized resin into a cavity of the mold, an injection unit 13 opposing to the injection unit 3 described above is arranged and also at the movable side 1b of the injection molding machine, by controlling a timing for injecting the resin material into a cavity 7a of the mold from the injection unit 3 arranged at the fixed side 1a of the injection molding machine described above and a timing for injecting the resin material into a cavity 7a of the mold from the injection unit 13 arranged at the movable side 1b of the injection molding machine described above are controlled by an electric circuit 14 and the resin is injected from the both sides to one cavity 7a of the mold to fabricate the product.
