What are the advantages of a hybrid injection molding machine over a full hydraulic injection molding machine?

Dec 06, 2019

For a long time, hybrid injection molding machines have dominated the injection molding machine market. However, with the development of all-electric injection molding machines, all-hydraulic injection molding machines are increasingly challenged. What are the advantages of the two injection molding machines? How will the full hydraulic injection molding machine respond to the challenges brought by the hybrid injection molding machine ... With many questions about these two injection molding machines, we interviewed relevant experts in this area.


    The main technical difference between the hybrid injection molding machine and the all-electric injection molding machine is that their power sources are different. Due to the different development levels of power drive sources, there are obvious differences between the two's implementing agencies and structures. Because the development of the actuator of the hybrid injection molding machine is restricted by the research and development level of the drive servo motor, the form of the actuator is less, and the form of the actuator of the full hydraulic injection molding machine is more available.


    In order to make the servo motor of the oil-electric hybrid injection molding machine produce a larger clamping force, its clamping mechanism is generally in the form of a toggle lever mechanism with a relatively small force expansion / large stroke. The full hydraulic injection molding machine can use a variety of mold clamping mechanisms. Since the form of the mold clamping mechanism determines the injection molding method of the injection molding machine to a certain extent, a hydraulic machine with a variety of mold clamping mechanisms can adapt to the processing requirements of more products.


    In addition, because the all-electric injection molding machine uses a ball screw to transmit power, the wear of the ball screw will necessarily affect the performance of the machine. Therefore, how to improve the service life of the ball screw, that is, to solve the problems of wear and lubrication, is a subject that needs further research. In contrast, the hydraulic transmission system of a full hydraulic injection molding machine does not have this problem.


In short, the products that can be processed by the hybrid injection molding machine can be processed by the hydraulic injection molding machine. That is, the injection molding range of the hydraulic injection molding machine is larger than that of the electric injection molding machine.
