Abstract
There are provided an injection molding machine having a screw that can be moved in a cylinder , a pressure commanding device for generating a pressure command value applied to the screw , a pressure sensor for sensing a pressure applied to the screw , a pressure subtracter for calculating a deviation value between the pressure command value of the pressure commanding device and a sensed value of the pressure sensor , a pressure amplifier for amplifying the deviation value of the pressure subtracter at a predetermined amplification factor and changing an amplification factor value based on a pressure value of the pressure sensor , and a servo motor driven based on an output value of the pressure amplifier to move the screw
