Nanjing Kerke has unveiled its new high-performance twin-screw extruder, adding another benchmark product to its lineup of high-performance mixing equipment

This high-performance twin-screw extruder incorporates an industry-leading modular design concept, with all key components technically optimized to balance performance and durability:
High-Torque Gearbox: Equipped with an 11.5 torque-class gearbox (specific torque of 11.5 Nm/cm³), it is suitable for high-power, high-output, and highly-filled material production lines. It offers high transmission efficiency, low operating noise, and significantly extended equipment lifespan, meeting the demands of long-term continuous production.
Customizable Barrel System: The barrel features a segmented modular design with built-in spiral water cooling channels and electric heating elements. Each segment is independently temperature-controlled, achieving a temperature accuracy of ±1°C. Barrel materials can be selected based on material properties, including 38CrMoAl, 45# high-chromium alloy, or WC-Co powder alloy liners, making it suitable for processing highly filled and highly abrasive materials.
High-wear-resistant screw elements: The core twin-screw elements feature a modular combination structure that can be freely configured to meet various process requirements, enabling material conveying, melting, shearing, mixing, degassing, and pressure-building extrusion. Elements are available in wear- and corrosion-resistant materials such as CPM-10V and SKD11, effectively extending equipment service life and reducing maintenance costs.
High-efficiency drive system: Equipped with high-efficiency, low-noise AC variable-frequency or permanent magnet synchronous motors, the system offers smooth operation and strong overload capacity. Customized configurations can be provided based on the customer’s on-site environmental requirements to achieve an optimal balance between performance and cost.
Wide range of applications, suitable for production needs across multiple industries
With its powerful mixing and processing capabilities, the high-performance twin-screw extruder covers a wide range of production scenarios across multiple industries:
Plastic blending and modification, as well as filled and reinforced pelletization;
Preparation of color masterbatches, functional masterbatches, and high-concentration masterbatches;
Modification and alloying of engineering plastics (PA, PC, PBT, etc.);
Processing of high-viscosity materials, such as reaction extrusion, devolatilization and drying, and recycled pelletization;
Compounding and extrusion of special powder materials, such as lithium-ion battery materials and electromagnetic materials.
