Pet Stretch Blow Molding

PET linear blowers from preforms. More technology, smaller size, less consumption.

PET / 2-Stage,
Stretch Blow Molding

Urola’s series of liner shuttle blowers produce containers from a variety of provided preforms.  Robust, proven technology, compact footprint and energy efficient.

The URBI series of linear shuttle, all electric blowers are robust, compact and ergonomically designed.  For container sizes up to 2.5 gal (10L), at rates ranging from 2,500 to 13,600 bph.  In view of: technologies offered, low cost of ownership and the output / cost ratio, the URBI could be your best solution.

1.

Unique (“L” layout) architecture, modular design; integrated preform feeding, linear oven, direct transfer system and blowing block press.

2.

The oven has several modules, with 8 or 9 lamps each. Air flow within the oven homogenizes the entire preform wall. Neck cooling via chilled air.

3.

Direct transfer system - Simultaneous transfer of the heated preforms from the oven to the mold and, the blown containers from the mold to the exit. No need to adjust spacing of the preforms for their transfer to the press.

4.

Stretch and blow systems driven by servomotors. Stretch movement in two phases; the approximation of the needle with a subtle preblow to stretch the bottle and the blowing to final geometry. Isobaric blowing outside the neck area to prevent any possible deformations.

5.

Shell inserts are fitted into a water-cooled shell holder. This system allows for quick format changes. The bases are mounted to a common base support (molds above 2qt (2L) are not shell type).

6.

Pneumatic compensation of mold closing ensures proper clamping and alignment to avoid ‘parting lines’.

7.

Easy-to-use control station: touch screen integrated to the frame to control blower settings and operations.

8.

Convenient access to the primary machine components for maintenance, adjustments and mold changes.

9.

The URBI-8 and URBI-4L models consist of two presses. A common hopper / singulation feeds both presses. A single outlet provides for the exit of containers.

Preferential heating

The preferential heating process is suitable for the manufacturing of complex PET bottles including asymmetrical or oval-shaped bottles and other flat containers. Urola has developed a simple and practical system with this objective, which can be applied to original equipment or retrofitted.

Air recovery

The Urola stretch blow molding machines combine the recovery systems of blowing air for the pneumatic drives of the blow molding operation.

As a result, offer considerable energy savings, eliminating the need for an additional low pressure air compressor.

Multi-layer

For complex multi-layer PET containers, Urola’s URBI line of stretch blow molding machines offers a great processing capacity and precision.
