Barrels and Relining

STEER Barrels are technologically advanced masterpieces, designed to deliver outstanding value. Made with the right metallurgy at our very own state-of-the-art foundry, they have supreme resistance to various types of wear encountered during the extrusion process. They are crafted for high performance, longer life and perfectly match with your existing co-rotating twin-screw extruder platform. We also make Liners for different barrels, depending upon applications and requirements.

THE STEER ADVANTAGE

STEER Barrels are available for a wide range of co-rotating twin-screw extruders. We manufacture barrels from 10mm dia to 300 mm dia (with a maximum length of 600mm). Each and every barrel is purpose-built with great attention to detail, offering you a host of advantages.

BUILT TOUGH. BUILT FLEXIBLE

Barrels have a toughened casing made of En8 and a liner of hard material. Liners are available with a choice of metallurgy — wear & corrosion resistant. These liners can be removed quickly as and when wear and tear occurs. Lined barrels come with 8-12mm replaceable liners.

CUSTOMISED METALLURGY WITH REQUIRED ACCURACY foundry

STEER Barrels come with a choice of metallurgy from our very own state-of-the-art foundry that makes some of the best tool steel in the world. Depending on your requirement, you can choose from our wear-resistance (WR) series and our corrosion resistant series.

COOLING CIRCUITS FOR INCREASED EFFICIENCY

STEER barrels have cooling circuits located close to the liner in the barrel. These circuits cool intensely and uniformly, optimising the efficiency of the process.

CUSTOMISED VENT INSERTS FOR BETTER PERFORMANCE

Vent barrels can be provided with three different types of vent inserts depending on the application and customer requirements. Plugs are provided for all vent barrels. STEER can also design new types of inserts based on customer request.

EXTREMELY QUICK TURNAROUND AND DELIVERY TIMES —

At STEER we understand the importance of keeping your business going. Our integrated manufacturing unit coupled with our state-of-the-art foundry help us ensure that you have minimum downtime, whether it is refurbishing your existing barrel or designing a new one based on your requirements. (*Type, size & quantity will determine the delivery schedule).

BEST-IN-CLASS QUALITY MANAGEMENT SYSTEMS At STEER we strive for perfection and you can rest assured that you are getting the best quality and a superior return on your investments.

  • Coordinate measuring machine inspection to check for accuracy in dimensions
  • Barrel leakage testing, done under 10 BAR pressure – twice the cooling line pressure in a TSE
  • Advanced Welding technique for sealing the cooling lines
  • Magnetic particle inspection to check for micro cracks
  • Hardness of liner measured using portable hardness tester
  • Dye penetrant test to check for cracks and blow holes
  • Nitrided barrels are checked for depth and surface hardness

REFURBISHING BARRELS AND LINERS

STEER undertakes the work of receiving and refurbising Barrels and Liners to give the product an extended life. Customized metallurgy and highly finished surfaces with high accuracy are the focus areas

Â

SPECIAL BARRELS

At STEER, we are constantly innovating and have developed a ‘Novel Technology with a Jiffy Clamp’ for special Extruders. The objective is to reduce time during assembling/changing and to take care of the forces of expansion during the heating process.
