Twin-Screw Calendering & Pelletizing Line

The line adopts a split barrel and modular screw elements, allowing flexible combination of conveying, shearing, mixing and venting sections. It supports compound modification, filling reinforcement, reactive extrusion, devolatilization and other complex processes, satisfying multi-material and multi-process R&D with one machine.

Multi-stage independent precise temperature control (accuracy ±1℃), together with the strong shearing and high dispersion performance of co-rotating parallel twin screws, ensures uniform distribution of nano-fillers, glass fibers and additives, with no dead zones and stable material properties.

Equipped with a precision calendering unit (3-roll / 5-roll, with adjustable roll temperature and gap), it can simultaneously perform film calendering, sheet molding and pelletizing. The pellets are uniform, full, pore-free and dimensionally stable, suitable for subsequent injection molding, blow molding and extrusion.

Adopts Siemens PLC and industrial touch screen for full-parameter visualization, one-key operation and real-time data recording/export. Servo motor drive enables closed-loop control of screw speed, feeding, traction and pelletizing, ensuring stable running, low failure rate and easy maintenance.

The quick-open split barrel design allows material change and cleaning without removing the screw, improving cleaning efficiency by 60%. The compact structure and easy movement make it ideal for laboratories with frequent formula changes and small-batch production.
