Abstract
The electric injection molding machine comprises a sensorservo motora motorand a controllerand, in a plasticizing process in which the motoris rotated, the controllerperforms control by repeating a first process in which the rotation of the servo motoris controlled by a first retreating speed command valueto make the screwretreat at a low speed when a screw backpressure signal is smaller than a backpressure set valueand a second process in which the rotation of the servo motoris controlled by a second retreating speed command valueto make the screwretreat at a high speed when the screw backpressure signal is larger than the backpressure set value
