    Detail

    The hydraulic standard solution "GS  energy saving Series" focuses on the mass market and is the most popular injection molding machine series in China and other countries throughout the world. The robust machine concept is fitted with high quality components and offers reliability and overall production consistency

    Cost-effective: Best price/-performance ratio

    Reliable: European components for electronics, hydraulics, electrics and drive

    Userfriendly: Latest control technology

    Modular: Up to three injection units for each clamping force and different screw sizes available


    Clamping unit

    • Proven 5-point double toggle
    • Free programmable core pullers with 1 to 6 circuits
    • Euromap (Spain) standard layout
    • New developed integrated safety bar
    • Automatic mold height adjustment
    • Optimized machine guarding design for fast and easy mold changing

    Injection unit

    • Up to three injection units per clamping force
    • Free selection of variable screws depending on application
    • Accumulator for increased injection performance (optional)

    Hydraulic

    • Sound-reduced and energy saving hydraulic pump
    • High-quality components for electronics, hydraulics, electrics and drive

    The injection machine with variable pump or servo motor controlling system is one of the energy saving series in our company. This series adopt high-speed response proportional variable system or servo motor energy saving system, which can make the power output of hydraulic system match with the actual consumption of the load and avoid the loss of energy. Compared to the machine with fixed pump control system, 30%-80% electricity energy can be saved, it shows obvious economic benefits. 
          
    In addition, the heat from the machine running is very low, it can reduce at least 30% cooling water consumption, which extends the service life of airproof seals and reduce the use and maintenance cost of machine greatly. This series with variable pump controlling system brings obvious economic benefits to wide customers relying on its excellent performance    .

        
    The following shows its main excellent performance:
    ◆ The variable pump series can save electrical energy from 30% to 50% comparing with fixed pump series.  While servo motor control system series can save energy by 40% up to 80%.
    ◆ Quick response of system, shorten the cycling time
    ◆ Very low oil temperature of this system prolongs the service life of machine 
    ◆ Equipped with high-pressure mold protection function and it can reduce the mold opening/closing impact, thus extends the service life of machine and mold

    ◆ Lower maintenance cost


    AC servo motor+ international brand pump  

    Energy saving: compared to traditional hydraulic system, saving energy of 20%-80%  

    Stable performance: closed loop control of servo motor brings higher repeatability.

    Reliable pressure holding: closed-loop of pressurecontrol, pressure holding can be longer and more stable  

    Fast response: agile servo motor only  

    Low noise and environment friendly: low noise during operation, more quiet during low speed; precise output of hydraulic oil avoid heat from extra oil output, have lower temperature rise and save a lot of cooling water
