In face of the urgent environmental issues, motor energy-saving technology is considered as one of the solutions to resolve global energy consumption and loss. There were 80,000 to 100,000 injection molding machines produced around the world. In the light of power systems, the machines can be divided into three types such as hydraulic, hybrid, and all-electric. More than 70% of electricity is consumed by the power system for injection molding machine. In order to use energy efficiently, most suppliers primarily manufacture and sell either hybrid or all-electric types in recent years. An injection molding machine can operate for more than 10 years; therefore, a lot of traditional hydraulic injection molding machines still exist in the plastic-manufacturing industry. Traditional hydraulic machines use mains electricity and fixed-displacement pumps. During the working procedures, energy of the power system goes through multiple transformations, and this results in low efficiency. This research analyzes the power systems of injection molding machines in detail and investigates different types of energy-saving power systems under the same productivity and quality conditions. The energy-saving power system designed in this thesis is integrated including servo-motor driver, AC synchronous motor, oil circuits, control circuits and system protection. The system can accurately control hydraulic parameters in different process stages. Therefore, the system can avoid the situations of energy loss and oil temperature rise caused by high pressure oil drain. From experimental analysis, the energy-saving power system can save about 59% of energy compared to the power system of the traditional hydraulic machine.
