THE NEW STANDARD IN COMPOUNDING

STEER’S REVOLUTIONARY OMEGA SERIES WITH 1.71 DO/DI

Overview

Features

Performance

Series Technical Specifications

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.

 

THE OMEGA SERIES OFFERS MANUFACTURERS 6 DISTINCT ADVANTAGES WHEN COMPARED TO CONVENTIONAL PLATFORMS

 

  • UP TO 25% INCREASE IN PRODUCTIVITY

    Up to 25%* more production capacity due to increased volume and torque ability. The High free volume leads to higher throughput.

  • ENHANCED PROCESS EFFICIENCY

    Improved process efficiency and quality* due to patented special elements with ‘fractional-lobe’ geometry, that allow for higher conveying capacity, uniform shear, and extensional flow.

  • MINIMAL ENERGY DISSIPATION

    Reduced energy dissipation* due to a narrower, sharper residence time distribution.

  • ABILITY TO WORK WITH SENSITIVE MATERIALS2

    Better control* over kneading, stirring and shear to give manufacturers the capability to work with sensitive materials.

  • IMPROVED CONVEYING EFFICIENCY

    Improved conveying efficiency, greater ROI and minimised downtime* due to self-wiping elements that prevent degradation.

  • SHARPER RESIDENCE TIME DISTRIBUTION

    Controlled processing with higher required mean shear, reduction in total shear as well as controlled residence time.

#1. 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.

 

#2. 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.

#3. PATENTED SPECIAL ELEMENTS – ENHANCED PROCESS EFFICIENCY

 

Purpose-built with a thorough understanding of mixing, special elements help overcome difficulties arising in advanced applications. Whether it is higher intake or side-feed capacity, greater forward conveying ability, extensional flow or better wetting action and improved flow distribution, our special elements are built to enhance efficiency.

#4. 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 .

#5. 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.

#6. STEER BARRELS – CRAFTED TO PERFECTION

 

barrelsSTEER 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.

#7. 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. STEER side feeders assure high consistency and precise dosing into the extruder, besides being completely noiseless.

#8. 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.

 

#9. 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.
