SFL 1XL for large sizes

The best manufacturing solution for large size containers

The SFL 1 XL linear blowers are the response for small- and medium-scale production of containers anywhere from 5 to 30 liters in size, dedicated to sectors as water, oil, beer, wine, household chemicals, mineral oils.
The SFL 1 XL is ideal for production of returnable or one-way containers for water dispensers, stackable/one-way containers, kegs for beer and a wide range of large size containers, with neck finishes up to 93 mm. A special feature is the automatic insertion of the handle inside the blowing mold.

Process steps: main features & benefits

Preform feeding
  • The preforms are discharged in bulk from octabins into the preform hopper
  • A soft drop preform octabin tilter is available as an option
  • From the hopper an elevator belt provides a continuous supply of preforms to a linear unscrambler
  • In the preform unscrambler, two counter rotating cylinders are aligning the preforms by gravity with the neck finish upward
Thermal conditioning
  • During the heating phase, the preforms are constantly rotated for a perfectly symmetrical distribution of heat
  •  Ventilated ovens to maintain preforms internal temperature at a sufficiently low level, avoiding excessively high temperature on the external wall of the preforms
  • Two ovens in standard configuration, a third oven can be installed to increase heating time
  • Preforms are carried in front of 16 (sixteen) IR lamps on one side and mirrors having vertical slots on the other side
  • As option, 45° or 90° lamps are available in order to fit special preforms
  • The stretch and blowing phase is made within a toggle blowing press with pneumatic compensation
  • The axial stretching of the preforms is carried out by a servo-driven stretching rod that provides a high level of repeatability and consistency
  • Once the bottle is completely formed and the blowing air is exhausted, the mould opens and the blown bottle is evacuated by a linear transfer system electronically synchronized to the blowing press movement
Software control
  • The automation and control of the blowing machine is carried out by a SOFT PLC
  •  A touch screen graphical interface allows to access to all the parameters for machine control, heating-blow moulding process, alarms and relative diagnostics and production statistics
  • A modem connection to the SIPA ON LINE is also provided for a remote customer support
