The SBO 6/10 has 6 molds and 10 heating modules.
Willwork with a wide range of bottle sizes and styles from 0.25 to 3 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 6/10 STRETCH BLOW MOLDERS
The preforms are held under the support ring by two rails before being lowered by gravity
to the feeder plate.
PREFORM HEAT CONDITONING
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 10 heat modules. 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.
At the outfeed of the heat conditioning unit the preforms are transferred to the blow
wheel by means of a transfer wheel.
The blow wheel comprises of 6 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.
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
Robustness and long lasting service components.
Transfer and mold open/close motions are controlled by rotary kinematics and fixed cam
Constant quality of bottle production based on the precision and repetition of stretch
motions, and automatic adjustment of camera controlled heating zones.
High productivity based on synchronization of all cam actuated motions and reduced dead
INTERCHANGEABLE MOLD SETS
Molds can be designed to fit the complete line of Sidel SBO stretch blow molders.
A single motor with simple motions actuated by timing belts and gears.
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.
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
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.
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.
