In the application of plastic machinery, mainly for extrusion and hydraulic station, hydraulic station in the application of energy-saving effect is very significant, saving up to 20% 6 5%, based on pressure transducer or c team’s signal automatically Pump speed to energy-saving machinery and to extend the life of purpose。

　　20% of the power-saving results in a 6S%。

　　 First, the main characteristics of：

　　●Power-saving results in 20% -65%

　　● Soft-start motor. Reduce the impact of machinery。

　　● Dynamic adjustment of the oil output。　

　　● No high-cut energy loss。

　　● Closed-loop control system, power output and pressure and flow control sync automatically follow. Significantly reduce the combined mode, the mode of vibration, stability, production technology, improve product quality, reduce mechanical failure, to extend the service life of the machine.

　　● The existing hydraulic system and control system without any changes. The system can co-exist with the original system, the same operation. Each other and can switch control。

　　● The protection of the system functions, with under-voltage, over-voltage, overload, short circuit protection, etc.。
Second, the scope of application of the proportional valve to control the pressure and plastic archery flow of a variety of injection molding machine.
