The reason why the all-electric injection molding machine is warmly welcomed by the sales market is that it is not energy-saving and environmentally friendly with a full-hydraulic injection molding machine. The specific manifestations are:
Environmental protection and energy saving is a major advantage of electric injection molding machines, because the AC servo motor is driven immediately according to the requirements of the actuator, which not only improves the efficiency, but also improves the energy utilization rate. Its kinetic energy utilization rate can reach more than 95%, so it is compared with the full hydraulic Compared with injection molding machines, environmental protection and energy saving are 25%-60%.
The injection performance is stable, and the various dynamic performance parameters of the full hydraulic injection molding machine are affected by the change of the hydraulic oil temperature, which is very easy to fluctuate. In contrast, most of the dynamic performance parameters of the all-electric injection molding machine are not affected by external factors. The main parameters of the mold on the machine are in line with the actual molding standards from beginning to end. Therefore, the accommodation performance is stable, and the rapid response of the main injection parameters is accurate, which can only be reflected in the AC servo motor system software.
High efficiency, the application of AC servo motor improves the responsiveness of the system software. Take a series of all-electric injection molding machines as an example. The molding time is only one third of that of a fully hydraulic injection molding machine. Because each actuator of the electric injection molding machine has an independent AC servo current driver, it will not be affected by the system software. , So you can perform compound poses. For example, the entire ejection process can be injected separately, and the entire melting process can be individually locked, thereby further improving production efficiency.
Save water, because the all-electric injection molding machine does not use a hydraulic shaft, and only needs to cool the circulating water at the feed port. Therefore, compared with hydraulic injection molding machines with load-sensitive pumps, the consumption of cooling circulating water can be reduced by 70%. Compared with the hydraulic injection molding machine with ordinary variable pump, the cooling circulating water can be reduced by 80%.
Optimize the working environment, do not use hydraulic oil, can keep the office environment clean, the equipment noise is more than 10dB lower than the full hydraulic injection molding machine, in addition to optimizing the working environment, due to the waste of the hydraulic transmission system, the injection molding machine occupies 15% of the total area.
In summary, all-electric injection molding has the advantages of fast speed, high efficiency, and high processing accuracy. It is more suitable for the production and processing of high-efficiency products such as electronic equipment, electrical equipment, and home appliances, especially the injection molding of small products, showing its high performance , The advantages of high-precision injection molding.
