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.

传统的注塑机是采用定量泵供油的，注塑过程的各个动作对速度、压力的要求也不一样，它是通过注塑机的比例阀采用溢流调节的方式将多余的油旁路流回油箱，在整个过程中，电机的转速是不变的，故供油量也是固定的，而由于执行动作是间隙性的，也并不可能是满负载的，因此定量供油就有很大的浪费空间。
