Advanced Co-rotating Twin Screw Extruder

Advanced Co-rotating Twin Screw Extrusion: Omega 1.71 Do/Di

The OMEGA SERIES sets a new standard in the

compounding industry. The revolutionary 1.71
Do/Di allows manufacturers to increase their
production capacity by up to 25%* with its
increased volume and torque ability. The
patented ‘fraction-lobe’ special elements
enhance process efficiency and quality of
output, while delivering far greater returns on
investment.

Absence of Pressure Peaks in Fractional Lobed Mixing Elements

FEATURES
A REVOLUTIONARY 1.71 DO/DI – A GIANT LEAP IN
PROCESSING WITH THE CAPABILITY TO PRODUCE UP TO
25% MORE
We’ve created a new standard in the compounding industry
with the 1.71 Do/Di Omega platform. The greater Do/Di
allows for greater volume to obtain greater effects of
kneading and stirring, without a reduction in torque capacity.

PATENTED ‘FRACTIONAL-LOBE’ DESIGN SCREW GEOMETRY

The OMEGA PLATFORM is built using the revolutionary ‘Fractional-
Lobe’ geometry, replacing the conventional integer-lobe design. This
design eliminates shear peaks and ensures a uniform transfer of
energy to the materials being processed, giving the capability and the
control to work with sensitive materials. Besides, it reduces the energy
consumed considerably, while improving overall quality.
Inside Omega
Shear Uniformity

Ÿ Barrel to Screw Gap and Screw to Screw Gap are maintained at less than 0.25mm to have fully wiping
effect rather than shearing effect
Ÿ Greater than 0.25mm, material can pass through at a low pressure values .
FEATURES

STEER BARRELS – CRAFTED TO PERFECTION

STEER barrels have cooling circuits that cool uniformly,
increasing the overall efficiency of the entire process.
Made with the right metallurgy, they have supreme
resistance to various types of wear and come with
supports designed with cross roller guides or ‘v’ guides
that allow for a sliding movement of about 15mm. The ‘u’
bracket on which the barrel rests has minimum contact
surface to reduce the heat transfer from the barrel to the
slider and support column, further increasing efficiency.

STEER SIDE FEEDERS

STEER side feeders allow you to add new materials
such as fillers, reinforcements, sensitive impact
modifiers, pigments etc into the melt. They become
important when split feed is essential due to the
volumes of feed materials. The STEER side feeder can
also be used for devolatizing applications through
side-venting. The side feeder is height adjustable
within a range and portable as castor wheels are fitted
to it.
FEATURES

STEER CONTINUA SPLINE

continua-spline ost commonly used shaft splines are
involute, circular or straight increasing the stress
concentration and causing severe damage to the
expensive screw shaft, the screw elements and the
gearbox during a surge in torque. The STEER
Continua Spline design, made of high alloy steel,
reduces stress concentration. It has a shaft adaptor
with circular rupture grooves. During a surge, only
the shaft adaptor breaks at the groove preventing
damage to the shaft, the elements and the gearbox .

STEER HITORQ GEARBOX

The STEER Gearbox is of a watch case design with a
housing of multiple chambers, made of high grade
casting, and uses hardened and ground gears of
DIN5/DIN6. While most gearboxes without
hardening, develop play and have to be used at
reduced speed and torque, STEER Gearboxes are
built for the fast lane with their ability to transmit
higher torque, minimal axial play, minimum backlash
and equal angular deflection, allowing for improved
process capability applications.
FEATURES
STEER SPECIAL TOOL STEEL – THE RIGHT
METALLURGY FOR LONGER LIFE
STEER uses only special grades of tool steel, with
high wear and corrosion resistance, developed in
our state-of-the-art foundry. Our ACROLLOY series,
a vanadium rich tool steel with alloying and micro-
alloying elements, and characteristics of Wootz
steel, works against the forces of abrasion, wear and
corrosion. With ACROLLOY, our platforms and
elements are capable of withstanding the most
difficult applications.

THE STEER HUMAN MACHINE INTERFACE

The STEER Human Machine Interface helps users
control and monitor the extruder and peripherals
through advanced communication links and
protocols. The drive is controlled from a touch
screen which operates through Programmable Logic
Controllers (PLCs). STEER allows for customisation of
the HMI screens, integration of peripherals, other
plant utilities and material system to achieve
complete plant automation. The software used by
STEER is highly reputed and used by some of the
largest companies around the globe.
