Global packaging and PET plastics machinery specialist SIPA of Veneto, Italy has introduced a new range of blow moulding machines to their SFL range.

Designed for the production of returnable PET bottles in a capacity range of 15-30 litres, the new low cost SFL 1XL blow moulding machine can produce 250-300 bottles per hour in neck finishes up to 93mm. It can also produce up to 700 stackable/one-way containers per hour.

Preforms are discharged in bulk from the hopper to the elevator belt, where they are unscrambled to align them with the neck finish upwards. They are then picked up by the loading cup that inserts them into the spindle and transfers them to the oven, with 16 infrared heating lamps on one side and vertical slots on the other.

The stretch and blowing phase is completed with a toggle blowing press featuring pneumatic compensation while the axial stretching is carried out via a servo driven stretching rod that provides a high level of repeatability and consistency. Once the bottle is blown, the mould opens to evacuate the bottle using a linear transfer system electronically synchronised to the blowing press movement.

The SFL blow moulders feature an Air Recovery System (ARS) that recovers the air exhausted from each blowing cavity into a machine embedded air vessel for redistribution to other plant areas where applicable.

SIPA is represented in Oceania by HBM Packaging & Plastics Technologies .
