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

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 option

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

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.

PETForm (1750 - 3200 kN)

Flexible and efficient modular platform for the production of preforms

PETForm (1750 - 3200 kN) Hybrid injection units
Schliessen/Close

Hybrid injection units

The hybrid injection units with special HPX screw geometries ensure rapid melting. Color pigments, blockers or other blends can be added homogeneously at high throughputs without subjecting the melt to unnecessary shear forces

  • Compact and reliable design
  • Injection axis with hydraulic storage support
  • Electric metering drive with water-cooled servo motor and spur gear
  • High performance HPX screws
  • Simple and quick material and color pigment change
Compact vertical clamping unit

Compact vertical clamping unit

Compact vertical clamping unit

The vertical clamping design ensures extremely high plate parallelism and reliably minimizes the wear of the forming components for molds with up to 12 cavities. With its lock-to-lock time of only 2.0 s, the PETForm clamping system is a leading high-performance PET unit.

  • Vertical two-platen design
  • Moving mold plate guided with columns
  • Smoothly controlled and hydraulically actuated opening and closing movements
  • Good accessibility for quick mold changes
  • Robust and reliable design
Removal gripper

Removal gripper

Removal gripper

Thanks to the lightweight gripper unit, maximum process speeds can be achieved with minimal clamping movement. This in turn minimizes energy requirements and production costs.

  • Horizontal removal axis with high acceleration and fast speed
  • Compact and lightweight gripper unit
  • Quick gripper change
  • Optimized removal process
Post-cooling unit
Schliessen/Close
Post-cooling unit

Post-cooling unit

85% of the required cooling process takes place in the separate 4-stage post-cooling station. This results in significantly lowered cycle times and high output performance.

  • Turnable cooling unit with a total of 4 stations
  • Intensive cooling with a water temperature of 7°C
  • Ejection onto a horizontal conveyor
  • Simple and quick insert change
  • Good accessibility and simple maintenance
