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

2-stage injection units

The injection unit of the PET-LINE is a unique in-house-development. The extremely high throughputs of a preform system are only made possible in the first place thanks to the unique design.

  • High-performance plasticizing unit with electric metering drive
  • Intrusion technology for maximum metering performance
  • Injection piston with hydraulic actuation (ShotPot principle)
  • Innovative and powerful valve technology
  • Highly precise and quick digital control of metering and injection processes
Adaptive drive unit with optimal energy efficiency

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

CPP option

CPP (Controlled Production shutdown after a Power outage) permanently monitors the power supply and provides sufficient energy in an emergency.

  • 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.

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

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.
