Process steps: main features & benefits

Injection system
  • Servo-driven
  • Continuous low-speed screw rotation:
    • No power peaks for screw restart, lower energy consumption
    • @ 700 kg/h (0.80 IV): 34 RPM
    • Lower stress on the material
    • Lower IV drop (< 0.015 dl/g)
    • Lower AA generated by the extruder
  • Possibility to use color up to 4% with NO throughput drop
  • 4 shooting pot designs:
    • P105: 4.200 g
    • P125: 6.000 g
    • P140: 7.500 g
    • P145: 8.200 g
  • 2 screw designs:
    •  120mm: up to 1.000 kg/h (low IV)
    •  140mm: up to 1.400 kg/h (low IV)
  • Best-in-class injection system for PCR (flakes) applications: the lowest throughput drop @ 50% PCR
Durable clamp design
  • Very smooth closing profile
    • less stress to the tooling components in the clamp closing phase
    • less vibrations, affecting overall system reliability in the long term
  • Perfect cleanliness
    • durable clamp concept with encapsulated toggle levers & linear guidance of the moving platen
  • Low machine and mold service costs
    • no high-pressure hydraulic cylinder to rebuild periodically
    • durable clamp design allows for very low maintenance costs
    • best-in-class platen parallelism for long mold life
  • High platen thickness for virtually no deflection & extended mold life
  • Even tonnage distribution in all toggle links
  • Active mold protection system, monitoring clamp closing profile at every cycle
Injection Mold
  • We design preform molds featuring:
    • Largest operating window
    • Maximized part quality
    • Reduced maintenance cost
    • Wear-resistant coating to grant a longer mold live
    • Optimized cooling layout to support fast cycle times and save energy costs
    • Lowest mold platen deformation, precision and reliability
  • Our hot runner systems deliver:
    • Xflow™ technology with low pressure drop: best in class balancing
    • Increased injection speed, shorter cycle time
    • Optimal preform weight distribution 
    • Thanks to the smoothed channels extremely low PET degradation and avoided dead spots (low AA)
    • Easy maintenance
  • Our cold half delivers:
    • Proprietary LongLife™ technology: range of solutions capable to extend component life for preform mold cold halves.  8 million life cycles guaranteed (flash < 0.2mm) without need of components refurbishing
    • Significant reduction of refurbishment costs
    • Proprietary XMould™ technology: Sipa innovation which allows reducing the friction between the molten PET and the molding surface of the injection stacks during the injection phase. Two major advantages: shorter cycle times and ultra thin preform molding capability
    • SmartLock™ stack design for unprecedented cooling for short-neck preforms

Post-mold cooling
  • Cooling air flows from the neck to the gate:
    • cooler air inside the preform = better body and neck cooling
    • pin follows the preform geometry = higher air speed, better cooling effect
    • pin very close to the dome = better base cooling
    • no need to cool air with separate dehumidifier = less energy
  • Air cooler at the outlet of the transfer box to decrease air temperature for better preform internal cooling
  • Air intake: 20°C 
  • Preform transfer system is independent from the clamp movement:
    • better accessibility during mold changeover 
    • higher flexibility in adjusting the transfer box speed for guaranteed part removal
  • Preform transfer system supported by 2 points:
    • less stress on the whole structure
    • no risk of misalignment with EOAT
  • Excellent accessibility to non-operator side for mold changeover: up to 1m access


  • PET
  • OPP
  • PLA
  • Recycled PET
  • R-PET flakes


  • Thin-wall preforms (for lightweight bottles for mineral water, edible oil)
  • Thick-wall preforms (for carbonated beverages)
  • Preforms for heat set bottles
  • Wide mouth preforms for jars
  • Long preforms for large size containers


Preform production systems series XFORM 250, 350 and 500 GEN4 can produce a wide range of preforms with excellent performance.
