What is the advantage of a fully electric injection molding machine than a fully hydraulic injection molding machine?

The all-electric injection molding machine is a processing injection molding machine whose all power is supplied by electricity. It is becoming more and more popular in the market. The main reason for its popularity is that it has performance that cannot be achieved by a fully hydraulic injection molding machine, mainly in:

1."Energy saving" Energy saving is the biggest advantage of an electric injection molding machine. Since the servo motor is directly driven according to the requirements of the force required by each actuator, it not only improves the efficiency, but also improves the energy utilization rate. The energy utilization rate can reach more than 95%. , So it can save 25%-60% energy compared with full hydraulic injection molding machine.

 

2.The injection performance is stable. The dynamic technical parameters of the full-hydraulic injection molding machine are affected by the change of the hydraulic oil temperature and are prone to fluctuations. In contrast, the dynamic technical parameters of the full-electric injection molding machine are basically free from external factors. Mold molding parameters always conform to actual molding conditions, so stable injection performance and rapid response to precise injection molding parameters can only be truly reflected in the servo motor system.

 

3.High efficiency, the application of servo motor improves the responsiveness of the system. Take a series of all-electric injection molding machines as an example. Its molding time is only 1/3 of that of a full-hydraulic injection molding machine. Since each actuator of the electric injection molding machine is driven by an independent servo motor, it is not affected by the system. It can perform compound actions, for example, it can be ejected at the same time during the mold opening process, and the mold can be closed at the same time during the plasticization process, thereby greatly improving the productivity.

 

4.Water saving. Since the all-electric injection molding machine does not use hydraulic oil, only cooling water is needed at the feeding port. Therefore, compared with the hydraulic injection molding machine with load-sensitive pumps, the cooling water consumption can be reduced by 70%, which is comparable to that of ordinary quantitative pumps. Compared with hydraulic injection molding machine, cooling water can be reduced by 90%.

 

5.Optimize the working environment. Because it does not use hydraulic oil, the working environment can be kept clean. The noise of the machine can be more than 10dB lower than that of a full hydraulic injection molding machine. While optimizing the working environment, the area of the injection molding machine is saved by 15% due to the cancellation of the hydraulic system.

 

6.What is the advantage of a fully electric injection molding machine than a fully hydraulic injection molding machine? In short, the all-electric injection molding machine is more suitable for processing electronic, electrical, electrical, and other high value-added products with its advantages of high speed, high efficiency and high precision. Especially for injection molding of small parts, it shows its high performance, Advantages of high-precision injection molding.

 

Compared with the fully hydraulic injection molding machine, the fully electric injection molding machine has many advantages:

 

1. Save energy and reduce production costs

 

Since each action of the electric injection molding machine is controlled by the corresponding servo motor, when a certain production action is performed, the other control motors do not need to run, thus greatly saving power consumption.

 

Generally speaking, the power consumption of an all-electric injection molding machine is only 1/3-1/4 of that of a full-hydraulic injection molding machine. In addition, the previous all-electric injection molding machine does not use hydraulic oil, eliminating the need to cool the working oil. The use of cooling water is greatly reduced, which can greatly reduce production costs for manufacturers.

 

2. High responsiveness and stability of production action control

 

Since all the movements in the production process of the all-electric injection molding machine are driven by the servo motor, its movement speed is high, the accuracy is high, and the hydraulic oil is not used, so that the various process parameters will not be affected by the change of oil temperature. High stability during the production process.

 

3. The low noise characteristics of the all-electric injection molding machine not only benefit the workers, but also reduce the investment and construction costs in the soundproof production workshop.

 

4. Ensure the cleanliness and safety of the working environment

 

Since the all-electric injection molding machine does not use working oil, there will be no environmental pollution caused by mechanical oil leakage, and the possibility of fire can be greatly reduced.
