From the perspective of technological research and development level, leading vertical injection molding machine manufacturers have achieved remarkable results in reducing equipment energy consumption with their strong R&D capabilities. For instance, some internationally renowned manufacturers have invested a significant amount of resources in the research and development of servo motor drive systems. Compared with traditional asynchronous motor drives, servo motors can accurately adjust the motor speed and torque according to the actual working requirements of injection molding machines, thus avoiding energy waste. When the injection molding machine is in low-load conditions such as pressure holding and cooling, the servo motor can automatically reduce its speed to decrease energy consumption. According to industry data statistics, vertical injection molding machines with servo drive systems can reduce energy consumption by 30% to 50% compared with traditional models. However, some small and medium-sized manufacturers, constrained by their research and development funds and technical capabilities, are still using relatively traditional drive technologies, resulting in relatively high energy consumption of their equipment.

　　The type and configuration of equipment also have a direct impact on energy consumption. Compared with hydraulic injection molding machines, all-electric vertical injection molding machines have obvious advantages in terms of energy consumption. The all-electric injection molding machine directly drives each actuator through a motor, featuring high transmission efficiency, low energy loss, and no problems such as oil leakage or pressure loss in the hydraulic system. Take the production of small injection molded parts as an example. When a fully electric vertical injection molding machine completes the same production task, its energy consumption can be 20% to 40% lower than that of a hydraulic injection molding machine. In addition, details such as the screw design of the equipment and the configuration of the heating system will also affect energy consumption. Some manufacturers adopt new types of screws to optimize the plasticizing process of materials, reducing heating time and energy consumption. In the heating system, new heating methods such as electromagnetic induction heating and infrared heating are adopted. Compared with the traditional resistance heating, they have higher thermal efficiency and lower energy consumption.

　　The application degree of energy-saving technologies is a key factor in distinguishing the energy consumption of equipment from different manufacturers. Forward-looking manufacturers actively apply intelligent control technology, install sensors to monitor the working status of injection molding machines in real time, and automatically adjust the equipment operation mode in combination with preset production process parameters. For instance, when the equipment detects that the mold temperature has reached the set value, it will automatically reduce the heating power to prevent energy waste caused by excessive heating. Some manufacturers have introduced artificial intelligence algorithms into the equipment control system. By learning and analyzing historical production data, they optimize the injection molding process parameters and further reduce energy consumption. However, some manufacturers, due to lagging technological updates, failed to apply these energy-saving technologies in a timely manner, resulting in persistently high energy consumption of the equipment.

　　In addition, the maintenance and usage of the equipment will also indirectly affect energy consumption. If manufacturers can provide comprehensive equipment maintenance plans and training services to help users operate and maintain the equipment correctly, it can ensure that the equipment is always in an effective operating state and reduce energy consumption. For instance, regular cleaning and maintenance of the hydraulic system to prevent hydraulic oil contamination and leakage can effectively enhance the working efficiency of the hydraulic system and reduce energy loss. Conversely, if the equipment lacks maintenance for a long time, problems such as component wear and system leakage will lead to a decline in the equipment's operational efficiency and an increase in energy consumption.
