1. High energy savings
Under normal operating conditions, compared with conventional
hydraulic injection molding machines, energy savings of 20-80%
can be achieved.
2. Molding stability
Compared with conventional injection molding machines repeatability
is greatly improved due to servo motor closed-loop control.
3. Quick response
Featuring a dynamic servo motor with a response time of only
0.05sec
4. Quiet operation
The machine runs at much lower noise levels, particularly in low
speed applications.
5. Reliable holding pressure
Compared with traditional hydraulic machine the holding pressure is
more stable and does not have limitation.
16 Better oil temperature stabitily
The servo system only delivers hydraulic oil as it is needed for
the various functions. This prevents unnecessary generation of heat
and substantially reduces oil cooling requirements.
Servo energy-saving system
Using the servo motor oil esectriciyt composite sturcture, high
response, low noile and excellent
electricity -saving performance.
The Hydraulic Units
High efficiency, Energy-saving and high precise proportional
pressure and flow variable displacement pump system make the out of
the hydraulic system matching the required power for entire machine
operation without loss of high pressure throttle and overflow
energy. As comparedwith constant displacement pump, t saves power
by 30%~60%.A motor with same power may be fitted with an oil pump
of bigger displacement and thus accelerates the speed of
machine.Besides, the low oil temperature will prolong the service
life of sealing elements.
Buffer device is used in every mold opening and clamping oil way to
ensure steady mold opening and clamping operation without any
impact.Besides, differential mold clamping operation is fitted to
ensure high production efficiency.
