pet plastic bottle blow injection molding machine for sale jars preform manufacturers in china ningbo production line

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.
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.

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.

Servo energy-saving system

Using the servo motor oil esectriciyt composite sturcture, high response, low noile and excellent

electricity -saving performance.
