Hydraulic closed loop and motor speed closed loop is realized by
control system with the features of high repetition, high
linearity, high linearity, high efficiency, high precision, fast
response, low rejection rate,low noise, low vibration and long
service life, High-rigidity template design with T shot andordinary
threaded hole facilitates the mold installtion. Oil filter
equipment of high performance and high precision can keep the
grease within NAS8. Color control system is adopted.
2. Injection Unit Features
2.1 Injection unit adopts duble-cylinder design, more higher
injection pressure, more simpler structure and lower malfunction
rate.
2.2 Enlarged-cylinder, adopting two -cylinder design,effectively
prevent the adhesive-material leaking phenomenon because of the
machine vibration or other reasons when the nozzle is under
high-speed operation.
2.3 Adopting graphite bush, improving the wear-resistance, reducing
the frequency of using lubrication oil effectively improve the
cleanness of the injection part.
2.4 Injection cylinder adopts low-frictional seals, improving the
response rate and improve the stability under the complicated
processes of injection.
2.5 Bridge-style design, for different L/D plastic parts.

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.
13.The Machine Introduction
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.
14.Some of the important features:
Clamping system: Faster response, steable and high rigidity.
Injection system: Accurate and flexible, lower rejection rate.
Control system: omputer and simple operation,molding data memory
system.
Power system: Energy saving, high efficient and precise.
Metal parts: The thickness of our frame, metal plate and wallboard
are thicker than other company.
Ceramic heating loop: Uniform heating, better thermal insulation
properties so good for production.
Visiable lubrication system: on time clean, avoid cast steel parts
abrasion and broken.
Oil treasure: Filter of hydraulic oil, good for pump and valves.
Long working life: Imported spare parts and updated version.
Aftersales service: Professional & timely.
