Process steps: main features & benefits

  • Continuous preform feeding system
  • Composite techno-polymers chain: very light, no wear, no elongations, low maintenance cost
  • Self-lubricate bushing and sealed bearing
  • Standard quick changeover of spindle (tool-less)
  • Different chain pitch to optimize production based on specific neck finish diameters
  • Ejection system for oval or not well inserted preforms
  • Quick-change system (option) in less than 5 minutes for different neck diameters: change of loading wheel and loading guides
  • Preforms ventilation system with laminar flow (sipa patent). No turbulence
  • Low thermal inertia: higher heating process consistency and fast start-up
  • Oven dimensions based on preform and max bottle size (from 8 to 16 lamps)
  • Modular oven
  • Adjustable position for neck change
  • Servo-driven pitch-change system to optimize heating efficiency (oven pitch) and maximum bottle diameter (bottle pitch)
  • Simple, solid and reliable system
  • Servo-driven unit for same-time preform and bottle transfer
  • Precise and gentle preform holding
  • Very high transfer speed
  • Quick change of personalized parts (tool-less)
  • Electrically driven blowing clamp, no oil.
  • Servo-driven motion with levers and oscillator.
  • High clamp speed
  • Double-sided pneumatic compensation.
  • Servo driven stretch rods.
  • Fine setting of stretch profile thanks to servo control.
  • Blow seals, fast and independent for every cavity.
  • Self-learning of stretch stroke based on preform-bottle size.
  • High tech blowing valves: fast and independent for every cavity, with individual pre-blow flow regulation 
  • Very quick exhaust
  • Single cavity pressure monitoring (option)
  • Standard Air tanks for peak blowing ramp, providing higher output 
  • By-pass valve to avoid chilled water when not in production
  • Less power consumption once machine is in idel mode or is waiting for downstream
  • No condensation on blow molds once the machine is not blowing bottles
  • Servo-driven unit for bottle discharge
  • Discharge on air conveyor or belt conveyor or vacuum conveyor
  • Bottle base cooling (option)
