1. A control method of an injection machine to control an injection pressure by a movement of a screw, comprising:

  • detecting the injection pressure generated when said screw moves forward in an injection process;

    predicting a rising injection pressure Δ

    P when decelerating the screw at a previously set deceleration of the screw from a time of detection of the injection pressure;

    comparing the predicted rising injection pressure Δ

    P and a previously set pressure P with each other; and

    decelerating said screw at a previously set deceleration based on a result of the comparison.
