Abstract
An injection molding method uses motors to effect measuring and kneading of a material to be molded and injection driving. The amount of movement of a rotary shaft or rectilinearly moving means connected to a screw is detected by a sensor, and the driving of the volume measuring motor and the injection motor is effected by the output of the sensor.
