POWERJET is an early and better dedicated equipment service provider for PET preform industry. We provide a comprehensive and mature solution for PET performmaking which leads the PET packaging industry for many years. Three models of high speed PET perform machines, with higher cost performance and clamping forces ranging from 3300kN to 5000kN, are specially developed for large production and have four advantages of high speed, precision, stability,and energy-saving.
Characteristic:
HPET preform injection molding system is developed & specialized for large quantities production, with four advantages: high speed, precise positioning, fast response, energy saving. The equipped mold adopting hot runner with pin valves and scientific cooling system design, which is the most competitive production line offering the integrated perfect solution of low cost and high performance.

|
|
|
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 shortens the cycle time.
|
Specialized PET screw increases the melting speed and quality, reduces the plasticizing temperature and AA value, which makes a great improvement for the preform shrinking and increases the transparency.
|
|
Control system adopts the famous brand of Euro computer, which is easy for operation with strong expandability, and can realize the real-time synchronization control of machine and robot running. The integration control of machine and robot is stable and reliable.
|
|
|
Accumulator with servo valve is adopted to control the injection accurately; two-circuit hydraulic design makes high speed and high efficiency, synchronization on plasticizing and opening-closing the mold to shorten the production cycle.
|
|
|
|
|
|
Unique accumulator with servo valve for ejector and opening-closing mold hydraulic control system ensures the ejection and opening-closing mold movement stable, fast and accurate, which can protect the mold efficiently, and match the requirement of take-out robot.
|
|
|
|
Specially designed high performance robot for preform taking-out is equipped with German SEW servo system, ensures the movement fast and stable, can provide 3 times cycle cooling outside the mold. The equipped ice water cooling system ensures the preform to be cooling down without stress. |
