- The low cost machine is ideal for the production of returnable containers - with a speed of 250-300 bottles per hour with neck finishes of up to 93mm.
- One way/stackable containers has a speed of up to 700 bottle 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 with pneumatic compensation and the axial stretching is carried out via a servo driven streching rod that provides a high level of repeatability and consistency. After the bottle has been blown, the mould opens and the bottle is evacuated by a linear transfer system electronically synchronized to the blowing press movement.
The SLF machine has a Air Recovery System (ARS) which recovers the air exhausted from each blowing cavity into a machine embedded air vessel, re-distributing it for other plant areas where applicable.
