An injection unit of injection machine operates to drive a time-belt pulley associated with a thrust bearing, a bevel ball-bearing, and a bearing nut to make a ball-bearing guiding screw move swiftly to in turn drive a movable plate to perform an injection stroke. The injection pressure transmitted backwards by a plasticized auger is sensed by a load bearer equipped with a pressure sensor something like a strain gauge. After an injection stroke, by means of another time-belt pulley and a shaft coupling, the plasticized auger is restored to its original position and ready for a next cyclic motion. During the cyclic injection process, the load bearer is in charge of sensing the pressure change and reckoning the back pressure in order to obtain the best injection quality.
