High Energy saving
Under the ideal working state, Power consumption is 40% less than
that of variable displacement pump and 70% less than that of fixed
displacement pump, save the cost effectively.
High precision
Precise control of low pressure & low flow, repeating precision
is less than 0.5%. Weight error of the products is 0.4%~0.7%, with
semi-close loop system nearly.
Fast response
With steady capability, servo gearshift dynamical control system
has equipped with pressure feedback device with high precision and
sensitivity, which forms close-loop precision control, cycle time
effectively shortened and improving production efficiency.
Oil temperature rise slowly
The system can restrain arising of oil temperature, so smaller oil
cooling system can be used in the machine.
PQ control
Control pressure and flow simply by inputting simulated voltage of
pressure & flow into the computer.
Low noise
Different from ordinary fixed pump injection molding machine, servo
power-saving injection molding machine is working only when
necessary. And working noise is less than LOG-A8 series, will be
much quieter for your working area.

Servo Machines Features
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.
6. 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.
