GENERAL INFORMATION

The SBO 4/6 has 4 molds and 6 heating modules. It can produce up to 4800 bottles per hour
in a wide range of bottle sizes and styles from 0.25 to 5 liters.

Sidel 2-step ^PET stretch-blow molders require previously manufactured preforms be 
supplied to the machine. Separating the bottle manufacturing and preform manufacturing 
processes allow production to be optimized, provide greater flexibility of operation and 
use, and provide higher production output rates and yield.

DESCRIPTION AND OPERATION OF SIDEL SBO 4/6 STRETCH BLOW MOLDERS

PREFORM FEEDER
The preforms are held under the support ring by two rails before being lowered by gravity 
to the feeder plate.

PREFORM HEAT CONDITIONING
The preforms are transferred neck up to the heat conditioning device. This unit 
continuously insures the preforms are inverted before passing, neck down, in front of the 
heating units and then inverts them again. During the heating phase, the preforms are 
rotated and their necks protected from the heat in order to optimize the distribution of 
heat without deforming the neck. Heating is insured by 6 heat units. Each unit can
accommodate up to 8 infrared lamps stacked horizontally whose ends are air cooled. The
heating power of 8 zones, corresponding to the 8 rows of lamps, can be controlled in
order to optimize the heat profile. These zones are regulated on all SBO Models. After
heating, a control by infra-red camera of preform temperature enables regulation of the
zones under control, thus insuring maintenance of the required temperature.

PREFORM TRANSFER
At the outfeed of the heat conditioning unit the preforms are transferred to the blow 
wheel by means of a transfer wheel.

BOTTLE STRETCH-BLOW
The blow wheel comprises of 4 molds of the pin type locking system whose opening and
closing are cam actuated. Each mold, cooled by inner circulation of chilled water, is
fitted in a mold-holding unit with integral mechanical locking. This system allows quick 
change of the molds. The blow nozzle is then inserted into the neck of the preform, thus 
guiding the stretching rod, which insures the preform's axial orientation. The blow,
which insures side orientation, takes place in two stages: medium pressure pre blowing
and high pressure blowing thus enabling optimum distribution of bottle wall thickness.
The blow nozzle insures perfect seal whatever the blowing pressure. The blow pressure 
control is integrated into the machine.

BOTTLE DISCHARGE
The bottles are discharged from the blow wheel by an outfeed wheel which transfers the 
bottles on a star wheel which pushes the bottles onto the machine outfeed.


TECHNICAL ADVANTAGES OF SIDEL SBO STRETCH BLOW MOLDERS

MACHINE RELIABILITY
Robustness and long lasting service components.
Transfer and mold open/close motions are controlled by rotary kinematics and fixed cam 
paths.

PROCESS RELIABILITY
Constant quality of bottle production based on the precision and repetition of stretch 
motions, and automatic adjustment of camera controlled heating zones.

PRODUCTIVITY
High productivity based on synchronization of all cam actuated motions and reduced dead 
times.

INTERCHANGEABLE MOLD SETS
Molds can be designed to fit the complete line of Sidel SBO stretch blow molders.

SIMPLICITY
A single motor with simple motions actuated by timing belts and gears.

VERSATILITY
Cabinet design enables easy access and fast interchange of molds and customization parts. 
Settings for heating, output rate, stretching, pre-blowing, and blowing can be quickly 
and independently changed. The process can be adapted to all types of preforms.

AUTOMATIC OPERATION
The main functions of startup and operation are combined on the machine integrated 
control panel. The role of the operator mainly consists of checking preform loading and
 output bottle quality.

BOTTLE WEIGHT REDUCTION
Optimization of material distribution based on precision of heat conditioning and stretch
 motions.

STAFF SAFETY
Machine startup can only proceed with the doors closed - opening them during machine
operation triggers an immediate shutdown of the machine. Noise levels are less than 85dB.

MACHINE SAFETY
Various safety systems avoid mechanical damage to the machine. Preventative safety 
systems, such as the ejection of sub-standard preforms before heat conditioning, ejection 
of unblown preforms and substandard blown preforms, etc. High speed shutdown of machine 
due to prevent abnormal stress levels etc.
