15.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.
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.
■ Computer Controller PLC
Professional injection moulding machine controller with software
and hardware of industrial standard is convenient to expansion and
revision of performance.
Adopting double CPU control makes high speed.
Mainly adopting PID control, the control accuracy reaches±1°.
Has the function of network management, improving efficency.
■ The Mould Adjusting Units
The automatic mold adjusting device driven by hydraulic motor
adopts gear coupling drive, features steadiness, high-efficiency
and saving mold loading time.
Characteristic
The machine use the high-performance servo dynamic control system,
the oil pump as the power source, having the characteristics as
follow: high response,saving energy, low noise, high-control
precision, and have the breakthrough in the prefect connection of
the electrical servo and hydraulic drive system.
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.
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 70dB, will be much
quieter for your working area.

12.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, it 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.
