Hydraulic driving technology is the most widely used driving control technology in injection molding machine at present. Developing from fixed displacement pump system, to proportional variable displacement pump system and closed-loop variable displacement pump system, today, servo-motor-driven hydraulic pump system has again promoted the hydraulic driving technology:
From variable tilting plate control to rotational speed control
From general AC asynchronous motor to AC servo motor drive
From analog control to digital control
The power output of the driving system highly accords with the load requirements of the machine and power loss is reduced greatly. Compared with the general injection machine, SM series can save 20%-80% power.

Perfect combination of electrical and hydraulic driving technology
Famous servo motor system + YUKEN dual-displacement piston pump
Low cost: Compared with the full electric injection molding machines, the production cost and maintenance cost of the servo injection molding machines have been greatly reduced.
Fast response: High efficiency piston pump realizes fast response injection molding which can be used in super-precision molding.
Easy for wiring: Integrate the controller with driver, simple wiring.
High performance: Special and high torque servo motor and variable displacement piston pump greatly improve the low speed molding and continuous pressure-holding performance with excellent repeatability.
Long service life: The servo injection molding machine adopts special servo coupling to avoid problems existing in coupling connection part.
