Helinco focuses on servo energy efficiency in industrial automation. For periodic running machinery such as: injection molding machine, die-casting machine, etc., can provide advanced technology for valve-free electro-hydraulic servo control systems. Valve-free servo system is an advanced servo control hydraulic power system with the advantages of energy conservation, high closed-loop accuracy, fast response speed, low noise, and simple oil routes. The energy consumption is the traditional hydraulic system. 30 % ~ 60 %. The high-voltage screw pump with patented technology has low pressure fluctuation, high volume efficiency, low noise, and high linear control accuracy.
