the hr
process
The HR (heat resistant) process makes packages than can withstand either hot
filling or pasteurization using a process known as heat setting. In this process,
preform heating temperatures are higher, and the bottle remains in contact
with the hot mold for a longer period.
This combination guarantees:
- The rearrangement of molecular chains at low stress levels, which limits the
effects of any subsequent uncontrolled shrinkage.
- An average increase in the degree of crystallinity of 32 percent. Reducing
the heat sensitive amorphous phase and extending the crystalline phase
increases the thermal strength of semi-crystalline material.

For optimum performance, the heat setting process must be combined with a
specially designed preform and bottle.
The HR preform profile guarantees specific biorientation ratios that limit internal
residual stresses while optimizing package weight.

The neck is especially heat sensitive, but there are ways to improve neck
strength in HR heat setting. It can be crystallized, or an amorphous neck can
be designed with added thickness.
Currently, new designs for amorphous 28 and 38 mm necks, which are lighter,
are in development for both inline and pre-manufactured applications.

1 - HR kinematics’ quick mold opening/closing and more stable transfer arms guarantee higher output rates.
2 – The built-in nozzle actuator, electrovalve and flow limiter assembly considerably reduces blow molding air consumption.
3 – The bell nozzle helps protect necks during blow molding (brevet Sidel).
4 – The open spindles keep necks from overheating in the oven.

Kinematics
made
for speed
Sidel offers a range of HR blow
molding machines with 6-30 cavities
to manufacture 10,800 - 51,000
bottles/hour. A number of features
including HR kinematics with quick
mold opening/closing and reinforced
transfer arms for greater stability;
reduced dead space; and advanced
preform and bottle design all guarantee
higher outputs.
Bottle
quality
assurance
The carefully managed heating profile
ensures superior material distribution
and contributes to package lightweighting. That profile is generated
by precision thermal conditioning
using the proven radiation oven
method combined with available
heating power.
Necks remain fully protected. Preforms
are reheated on spindles with an
open, ventilated design that keeps
necks from overheating in the oven.
The bell nozzle (Sidel patent) also
helps protect necks during blow
molding.
The pre-blow phase is started
independently and parameterized at
the control console. This provides
better control of material distribution
at every station to guarantee production consistency and package quality.
The cooling time (40 bar air injection
to cool the internal wall of the bottle)
is individually adjusted at each station
to reduce volume variation. It can
also be automatically modified in the
early production phases to reduce
the effect of the thermal transition
phase of the molds.
Parts
costs trimmed
Because HR kinematics reduce
inertia and mechanical stress, parts
do not wear out as quickly. That
reduces the cost of parts needed
to keep up with faster production
rates.
Air
consumption
under control
The built-in nozzle actuator, electrovalve and flow limiter assembly
considerably reduces dead space in
the air circuits. This cuts down on
blow molding air consumption. The
blow molding air recovery option
reduces air consumption by 15-25
percent.
The advanced cooling cycle can
save 6-10 percent in air consumption.
A
versatile machine
The Universal HR machine can be
reversed for standard production
applications. A recipe change at the
control console resets parameters of
thermal conditioning to implement
cooling, and the 40 bar air injection
is deactivated.
The three-passage rotary union
increases the HR blow molding
machine’s versatility for standard
applications. It can also improve
the mold housing unit’s thermal
insulation. The Quick Change system
facilitates format changeovers (neck,
preform and body).
Innovative technology for production
rates up to 1,800 bottles/hour/mold
Special HR
Total
flexibility
kinematics
A special HR cam makes faster mold
opening/closing possible, so that the
bottle disengages more easily to limit
shrinkage (bottle deformation). Special
kinematics also makes a broad range
of output rates (750-1,800 bottles/
hour/mold) possible. Advanced HR
kinematics (650 bottles/hour/mold) are
also available for the most sensitive
HR processes like 2-liter rectangular
bottles.
Man/machine
inter-
face performance
The oven’s special configuration is
based on a highly flexible heating
profile and total control of production parameters. The oven’s cooling
ramps are mechanically adjusted on
an individual basis to protect necks.
A regulated or total heating distribution system in the oven features
a modular design. Both of these
elements serve to increase the HR
system’s flexibility.
The sophisticated man/machine
interface closely monitors the quality
of production and processes in a
centralized system that controls
process parameterization (regulating
the heating profile and controlling HR
blow molding parameters), temperature control (temperature probes in
the mold), yield tracking, and maintenance.

Bottles made With aluminum molds
Sidel has a technology that combines
the benefits of F300 aluminum with
HR process temperature requirements.
This enables Sidel to reduce costs
and delivery times compared to production using stainless steel molds.
Lightweight F300 aluminum makes
faster output rates and format changeover times possible.
sBo universal hr
With aluminum, mold temperatures
can be raised and lowered more
quickly resulting in faster machine
restarts following format changeovers.
And since aluminum is lighter than
steel, output rates can be increased
while limiting mechanical wear and
tear on the machine for increased
overall productivity.
a vital component of the complete
The SBO Universal HR can be part
of a complete Sidel line for hot filling
sensitive drinks. The Veloce H filler
was designed to package products
like tea and energy drinks. It is also
ideally suited to filling juices with or
without pulp.
6 _ SBO Universal HR
Aluminum molds are easier to work
with. They are lighter, so they are easier
and faster to handle and install, and
they improve operator safety. Aluminum molds are easier to clean thanks
to an innovative surface treatment
developed by Sidel. This keeps cavities
in better condition in spite of repeated
maintenance needed to eliminate
oligomer deposits.
Thanks to the equipment’s unique
product recycling system, the filling
temperature remains constant regardless of production conditions even
during a machine shutdown. Product
quality and taste are completely protected.
hr
The wide variety of HR mold configurations (inserts, shoulders, etc.),
using either F300 aluminum or steel,
make it possible to produce many
different shapes in a single mold. For
each bottle capacity, there are specific
HR mold formats (Universal molds for
standard formats, Jumbo molds for
large containers).

The Veloce H filler guarantees excellent hygiene. The interior of the
machine is clean and sanitized. The
sloped frame is specially designed
to easily eliminate product or bottle
residues.
A dummy bottle system performs
closed circuit cleaning to guarantee
superior hygiene in filling zones. An
air filtration system can be added for
increased hygiene.
