The all-new PET-LINE with removal to the side

The most modern and efficient preform system in the world

Powerful injection unit

Powerful injection unit

The highly energy-efficient, two-stage injection unit enables shorter cycle times thanks to an optimized and adapted plasticizing and injection process. Intrusion and automatic metering ensure homogeneous and constant melt quality, low AA values and gentle material feed.

Your advantage:
Thanks to the optimized design of the new PETX screw, users benefit from the large process window and a robust plasticizing process also for rPET and additives.

CYCLE GUARD
Schliessen/Close

CYCLE GUARD

The optional available Cycle Guard monitors permanently the power supply and provides sufficient energy in an emergency. Cycle Guard does not require batteries or accus and is therefore particularly low-maintenance and cost-effective in operation.

  • Brief power failures or fluctuations in the grid lasting milliseconds are reliably bridged.
  • If the outage lasts somewhat longer, then sufficient power is provided to reliably and controllably shut down the cycle. Preforms are fully injected and demolded. Meterage for the next shot is stopped and the entire system is controllably brought to a halt. After a short system check, production can be quickly restarted.

Your advantage:
Cycle Guard increases machine availability in harsh industrial environments and reliably secures your productivity at lowest unit costs.

Latest generation aXos control system

Would you like to operate your PET system as safely and intuitively as possible?

The completely new aXos control unit provides an innovative combination of touch operation and haptic keys. Navigation always takes place on the central touch screen. Movements, on the other hand, are triggered via haptic keys with explicit feedback. "NETSTAL SMART OPERATION" comes as standard and enables simple, fast and safe start-up and production at all times.

Smartly engineered detail solutions

Don't the details often make the difference?

With the new PET-LINE we have created the most powerful PET system that enables our customers to produce the best preforms at the lowest unit costs. For this, every manufacturer needs a system that is intuitive to operate and easy to maintain. In order to achieve this, we paid attention to every detail when developing the system, no matter how small.

Electric clamping unit

Electric clamping unit

The electrically driven clamping unit with five-point twin toggle lever impresses with low energy consumption, maximum speed and perfect precision.

Your advantage:
The harmonious and smooth-running kinematics ensure minimum wear and tear of your valuable preform mold. Maximum availability thanks to simplified mold installation and change. The extremely robust design assures several million cycles per year and many years of reliable continuous operation.

Fast post-mold cooling unit

Fast post-mold cooling unit

The new sideways positioned post-mold cooling unit enables shorter cycle times due to its high dynamics. Up to 4 post-cooling stations are available.

Your advantage:
The integrated conveyor belt and the low-rebound ejection ensure that preforms are removed with absolute reliability. The efficient internal and external cooling assures a very high preform quality.

Two-component version

Two-component version

The PET-LINE 2C is a high-performance injection molding system for barrier applications and two-component preforms with decorative effects. The lateral injection unit can simply be deactivated. This provides complete flexibility and, if necessary, it can also produce monolayer and standard preforms for water and carbonated soft drinks (CSD) with up to 72 cavities.

Calitec® – the smart way to reduce cycle times

In order to improve the preform post-cooling, the demolded preforms are actuated with internal pressure via the transfer gripper.
That ensures a more intensive and, most importantly, uninterrupted post-cooling of the preforms. A calibration of the external preform diameter is carried out at the same time

Your benefits:
Faster cycle times and optimal preform quality

Toggle lever clamping unit

Toggle lever clamping unit

Toggle lever clamping unit

The clamping unit of the PET-LINE is based on the proven mechanical system of the SynErgy and was optimized in the course of different evolutionary steps with state-of-the-art digital control technology.
It is tailored to the specific requirements of PET preform molds and thereby offers optimal framework conditions.

  • 5-point dual toggle lever with hydraulic actuating cylinder for quick and harmonious movement sequences
  • Robust and stable design
  • Stable support of moving mold plate on sliding guides and columns
  • Perfectly designed for large and high-cavity molds
