Traditional plastic injection molding machine relies on constant rate pump in oil supply, and each action in the process of plastic injection may have different requirements on speed and pressure. The surplus oil flows back to the oil tank through the proportioning valve in the way of flooding adjustment. In the whole process, the rotation speed of motor remains unchanged, so the oil volume is fixed as well. Furthermore, the action is intermittent, and not of full load, so a great amount of oil is wasted.
