NANJING LESUN SCREW CO.,LTD

Precision Engineering in Twin Screw Extruder Parts

At Lesun, we specialize in providing high-performance twin screw extruder parts to meet the evolving demands of various industries. As a leading twin screw barrel manufacturer, we offer innovative and customizable solutions, from the twin screw and barrel to precision extruder shafts and other components.

Twin Screw and Barrel Customization

We provide tailored twin screw extruder barrels, ensuring durability and efficiency across different applications. Our product line includes both co-rotating and counter-rotating twin screw extruders, with custom options available to match unique requirements. Each extruder barrel is manufactured using high-quality materials to ensure longevity, precision, and excellent performance under varying operational conditions.

Advanced Twin Screw Technology

Lesun's twin screw barrel solutions are designed with high output and precision in mind. Our extruder shafts are crafted from specialized materials, enabling them to function efficiently at speeds of 900 RPM or more. We provide a choice of transmission box configurations, including the traditional 3-axis drive and the double-sided gear symmetrical drive. These innovations ensure reliability and extend the lifespan of the equipment. To further enhance durability, we utilize high-quality bearings from SKF (Sweden) and INA (Germany) in all gearboxes.

High-Quality Materials for Extruder Barrels

Our twin screw extruder barrels are fitted with industry-standard high-chromium iron Ω101A oval liners. For operations requiring high resistance to wear and tear, we offer high-vanadium cast iron Ω102A liners, which deliver extended service life compared to conventional models. Furthermore, for applications involving corrosive materials, we provide nickel-based high-chromium alloy Ω301A liners, enhancing the corrosion resistance of our twin screw extruder spare parts.

Precision Engineering for Optimal Performance

The thread design and meshing surface of the kneading disk on our twin screw barrels ensure consistent, precise clearance during operation. This precision allows for superior material mixing, higher granulation product density, and enhanced physical properties in the final output. For instance, our SHJ-H-27/48 model features a 0.15mm unilateral clearance, showcasing better material mixing effects compared to other leading twin screw extruder parts in the market.

Innovative Control Systems for Twin Screw Extruders

Lesun's twin screw extruder barrels are integrated with advanced control systems, featuring the HPCS-2000 control software, which allows for seamless monitoring of all extrusion processes—from formulation to feeding and forming. Our DC motors are regulated by Eurotherm and Siemens speed controllers, while AC motors use Mitsubishi or Fuji AC frequency converters, controlled by Siemens PLC systems. This setup guarantees stable and reliable operation across all extruder systems.

Company Profile

Comprehensive Safety and Precision

Our twin screw extruder spare parts come equipped with high-precision RKC temperature control instruments from Japan. These systems offer features such as artificial intelligence adjustment, two-way PID settings, and overload protection, ensuring long-term operational safety and accuracy. Additionally, our equipment includes advanced safety features like current overload protection, motor interlocks, head pressure alarms, and torque limit interlocks.

Conclusion

Lesun is committed to being a global leader in the production of twin screw extruder parts. Our focus on high-quality materials, precision engineering, and advanced control systems ensures that our twin screw and barrel components meet the highest standards of efficiency and durability. As a trusted twin screw barrel manufacturer, we continue to push the boundaries of innovation in the extrusion industry, providing solutions that enhance productivity and deliver lasting value to our customers.
