Nanjing Lesun Boosts Extrusion Efficiency with Composite Barrels

In the high-stakes world of industrial extrusion, barrel wear and corrosion have long been persistent challenges, leading to inconsistent product quality and operational inefficiencies. At the heart of these precision machines lies a critical component that determines success: the extruder barrel.

Nanjing Lesun Screw Co., Ltd. has pioneered a groundbreaking solution with its Combibarrels technology, designed to redefine extrusion performance. These innovative barrels feature strategically placed openings - a top vent for efficient degassing to eliminate bubbles and material defects, and side ports for simplified maintenance access, significantly reducing downtime.

Material Innovation: The Engineering Behind Superior Barrel Performance

Lesun's research-driven approach has yielded three distinct material configurations, each addressing specific operational challenges:

1. Bimetallic Liner with 45# Steel Housing: This dual-material construction combines a wear-resistant alloy inner layer with structural steel support. The design allows for cost-effective liner replacement when worn, significantly reducing maintenance expenses while maintaining performance.

2. N00 Nitriding Steel: Through specialized nitriding treatment, these barrels develop a hardened surface layer that resists both mechanical wear and chemical corrosion - particularly valuable when processing abrasive or corrosive materials.

3. H6/D11 Premium Alloys: Representing the pinnacle of barrel technology, these high-performance alloys deliver unmatched durability in extreme conditions while maintaining practical repairability, minimizing production interruptions.

These technological advancements in extrusion barrel design represent a significant leap forward for industries ranging from plastics and rubber manufacturing to food processing and pharmaceutical production, where consistent quality and operational efficiency are paramount.
