HPET series high speed PET preform injection molding system is special optimized with stronger driven system, use new technology of synchronization action, nitrogen injection, cooling system take out robot and other new designs(designs is different for different model).

Fast and efficient
Fast Computer: Euro branded controling system, which is easy for operation with strong expandability and can realize real-time synchronization control of machine and robot running.

Fast Injection: Accumulator with servo valve is adopted to control the injection, which makes the accurate shot;
The synchronous plasticizing and injection ensures the application of big injection volume and shorten the the circle time.

Fast mold open: Unique accumulator with servo valve for ejector and opening-closing mod hydraulic control system ensures the ejection and opening-closing mold movement stable, fast and accurate. This can protect the mold efficiently and match the requirement of take-out robot.

Fast Robot: Special designed high performance robot for preform taking-out is equipped with German SEW servo systerm, ensures the movement fast and stable, can provide 3 time cycle cooling outside the mold.

The equipped ice water cooling system ensures the preform to be cooling down without stress.

Efficiency Hydrauli Circuit System: Accumulator with servo valve is adopted to control the injection accurately; Two-circuit hydraulic designs makes high speed and high efficiency, synchroniztion on plasticizing and opening-closing the mold to shorten the production cycle. Synchronization pressure holding and plasticizing: Optional unit with pressure holding and plasticizing at the same time, which can increase the output by 15%~25%

Reliable：

Euro branded controling system is adopted for injection, recovery, plasticization, mould clamping and ejection.

Closed-loop servo valves enables the machine to react fast and precisely to the PLC signals.

Branded servo driving systems ensure fast and accurate moving of the robot plate.

Energy Saving

Multiple differential circuits mechanism is used for hydraulic control of the machine, which reduces lost energy

Servo motro or variable pump is optional. Energy saved by 30%~50% with servo motor while 25%~45% with variable pump.
