The reason why all-electric injection molding machine is popular in the market is that it has the performance that cannot be achieved by all-hydraulic injection molding machine, mainly in the following aspects.
"Energy saving" is the biggest advantage of electric injection molding machine, because the servo motor is driven directly according to the force requirement of each actuator, which not only improves the efficiency, but also improves the energy utilization rate, and the energy utilization rate can reach more than 95%, so it can save 25%-60% of energy compared with the full hydraulic injection molding machine.
The dynamic technical parameters of full hydraulic injection molding machine are affected by the change of hydraulic oil temperature, which is easy to fluctuate, compared with the dynamic technical parameters of full electric injection molding machine, which are basically free from the interference of external factors. can be truly reflected.
High efficiency, the application of servo motor improves the responsiveness of the system. Take a series of all-electric injection molding machine as an example, its molding time is only 1/3 of that of all-hydraulic injection molding machine. Since each actuator of electric injection molding machine is driven by independent servo motor without the influence of the system, it is able to perform compound action, for example, it can be ejected at the same time during mold opening and can be closed at the same time during the plasticizing process, thus greatly improving productivity.
Water saving, since the all-electric injection molding machine
does not use hydraulic oil and only needs cooling water out of the filling port, the amount of cooling water used can be reduced by 70% compared to the hydraulic injection molding machine with load-sensitive pump, and 90% compared to the hydraulic injection molding machine with ordinary dosing pump.
Optimize the working environment, because no hydraulic oil is used, the working environment can be kept clean, and the noise of the machine can be more than 10dB lower than that of a fully hydraulic injection molding machine, and while optimizing the working environment, the area occupied by the injection molding machine can be saved by 15% due to the elimination of the hydraulic system.
In short, with the advantages of high speed, high efficiency and high precision, all-electric injection molding machine is more suitable for processing electronic, electrical, electrical appliances, and other high value-added products, 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 machine, fully electric injection molding machine has many advantages.
Energy saving and lower production cost. Since each action of the electric injection molding machine is controlled by the corresponding servo motor, the other control motors are not required to run when a certain production action is performed, thus greatly saving power consumption.
Generally speaking, the power consumption of all-electric injection molding machine is only 1/3-1/4 of that of all-hydraulic injection molding machine. In addition, the former all-electric injection molding machine does not use hydraulic oil, which eliminates the cooling step of working oil, thus significantly reducing the use of cooling water, which can greatly reduce the production cost for manufacturers.
The high responsiveness and stability of the production action control, because the all-electric injection molding machine production process is driven by the servo motor, its action is fast, high precision, coupled with the non-use of hydraulic oil, so that the process parameters will not be affected by oil temperature changes, so the production process has high stability.
The low noise characteristics of all-electric injection molding machines not only benefit workers, but also reduce construction costs in soundproof production plants.
The cleanliness and safety of the working environment are guaranteed. Since all-electric injection molding machines do not use working oil, there is no environmental pollution caused by oil leakage from machinery, and the possibility of fire is greatly reduced.
