In the heart of every Twin Screw Extruder, the Extruder Barrel plays a critical role in transforming raw material into high-quality final products. As part of the continuously variable-volume processing chamber, the barrel works hand-in-hand with screw elements to facilitate conveying, melting, mixing, degassing, and pressurizing—functions essential to any high-efficiency Plastic Extrusion or Compounding Technology line. At Lesun Screw, we specialize in the design and manufacturing of premium Extruder Barrel components that ensure maximum performance, precise alignment, and long-term durability—even under high torque and abrasive processing conditions. What Makes a High-Quality Extruder Barrel?
Consistent Material Flow – Smooth inner surfaces and precision machining ensure stable throughput.
Effective Heat Transfer – Optimized barrel design allows efficient heating and cooling across the processing zone.
Accurate Screw Alignment – High concentricity ensures proper screw engagement and minimal wear.
High Strength & Rigidity – Engineered to withstand high torque, pressure, and mechanical stress.
Superior Wear and Corrosion Resistance – Optional integrated liners and advanced materials extend service life.
Precision Inner Bores – Machined to strict tolerances to maintain alignment and process consistency.
