Abstract
An electric injection molding machine capable of maintaining a quality of molded articles and capable of minimizing weight variation of molded articles. An electric injection mechanism injects molding material into a mold using an electric motor. An injection control unit and a servo driver control the motor so as to follow an injection speed reference. A compensation unit compensates the injection speed reference based on characteristics of a hydraulic drive system so that fluctuation of injection speed with respect to the injection pressure approximate the fluctuation characteristics of a hydraulic injection mechanism.
