Rotary beverage plastic bottle blow moulder machine

Preforms loading Star-wheel preform feeding system

• Pneumatic gate releases preforms into the star-wheel.
• Preform is loaded onto the spindle (and not viceversa) by means of cam track-driven grippers.
• No chain axial movement.
• Quick star-wheel changeover.

        Preforms handling and transport chain:

• Simple chain in special plastic material. No maintenance cost and time.
• No rotation of chain around its axis and no movement up and down to collect the preform.
• Dry operation (no grease).
• Quick tool-free spindle changeover when handling different preform neck.
• Possibility to change chain pitch to blow neck up to 43 mm.
• Very low maintenance cost

Thermal conditioning Modular heating oven

• Innovative ventilation through the lamps to maximize heat transfer by radiation (convection minimization).
• Neck ventilation inside heating oven for light-weight effective neck cooling
• 8 lamps (first 3 kW, the others 2 kW). Possibility to install all lamps of 3 kW, and an additional lamp for longer preforms.
• Low thermal inertia: heat process consistency and quick cold start-up.
• Low oven temperature: low consumption.

Preforms & bottles transfer

• Simple transfer movement.
• Only one cam needed.
• Smaller diameter.
• Preforms & bottles centrifugal forces are very low.
• Soft and smooth manipulation of preform and bottle necks.
• Very easy adjustment.
• Removal of speed limiting factor.

Stretch-blowing

• Reduced pitch between two molds: relevant space saving for the blowing wheel compared to equivalent machines.
• Smaller diameter.
• Lower inertial load and peripheral speed.
• Simplified transfer wheel, small diameter, lower peripheral speeds.
• Easier to maintain - accessibility of key elements.
• Shell mold, reversible modification to mount major competitors molds.
• Quick molds change-over

Bottles ejection

• Servo driven unit for bottle discharge.
• Discharge on belt conveyor or air conveyor directly feeding the filling lines.
• Bottle base cooling option
