Reason why all-electric injection molding machines are popular in the market is that they have performance that cannot be achieved by all-hydraulic injection molding machines, which are mainly reflected in:
"Energy saving". Energy saving is the biggest advantage of electric injection molding machines. Since servo motor is directly driven according to force requirements of each actuator, it not only improves efficiency, but also improves energy utilization. Its energy utilization rate can reach more than 95%. , so it can save 25%-60% energy compared to a fully hydraulic injection molding machine.
Injection performance is stable. Dynamic technical parameters of fully hydraulic injection molding machine are affected by changes in hydraulic oil temperature and are prone to fluctuations. In contrast, dynamic technical parameters of all-electric injection molding machine are basically free of interference from external factors. Mold molding parameters stored in the computer always conform to actual molding conditions, so injection performance is stable, and rapid response to accurate injection molding parameters can only be truly reflected in servo motor system.
High efficiency, application of servo motor improves reactivity of system. Taking a certain series of all-electric injection molding machines as an example, molding time is only 1/3 of that of a fully hydraulic injection molding machine. Since each actuator of electric injection molding machine has an independent servo motor drive and is not affected by system, it can perform compound actions. For example, mold can be ejected at the same time during mold opening process, and mold can be closed at the same time during plasticizing process, thus greatly improving productivity.
Water saving. Since all-electric injection molding machine does not use hydraulic oil and only needs cooling water at feeding port, compared with hydraulic injection molding machine with a load-sensitive pump, usage of cooling water can be reduced by 70%, compared with hydraulic injection molding machine with an ordinary fixed-displacement pump, cooling water usage can be reduced by 90%.
Optimize working environment. Since no hydraulic oil is used, working environment can be kept clean. Noise of machine can be more than 10dB lower than that of a fully hydraulic injection molding machine. While optimizing working environment, due to elimination of hydraulic system, area occupied by injection molding machine has been saved by 15%.
In short, with advantages of high speed, high efficiency and high precision, all-electric injection molding machine is more suitable for processing high value-added products such as electronics, electrical appliances, etc., especially for injection molding of small parts, which shows its advantages of high performance and high precision injection molding.

 

Compared with fully hydraulic injection molding machines, fully electric injection molding machines have many advantages:
Save energy and reduce production costs. Since each action of electric injection molding machine is controlled by a corresponding servo motor, when a certain production action is performed, other control motors do not need to run, thus greatly saving power consumption.
Generally speaking, power consumption of an all-electric injection molding machine is only 1/3-1/4 of a fully hydraulic injection molding machine. In addition, previous all-electric injection molding machine did not use hydraulic oil, which eliminated cooling step of working oil, thereby greatly reducing use of cooling water, which can greatly reduce production costs for manufacturers.
High responsiveness and stability of production action control. Since all actions in production process of all-electric injection molding machine are driven by servo motors, which have fast movement speed and high precision, and do not use hydraulic oil, various process parameters will not be affected by changes in oil temperature, so it has high stability during production process.
Low noise characteristics of all-electric injection molding machine not only benefit workers, but also reduce investment and construction costs in soundproof production workshops.
Ensure cleanliness and safety of working environment. Since all-electric injection molding machine does not use working oil, there will be no environmental pollution caused by mechanical oil leakage, and possibility of fire can be greatly reduced.
