Polyester Fiber Bundled Geogrid Strip Extruder

The polyester fiber bundled geogrid strip extruder is a high-performance machine specifically designed for the continuous production of geogrid strips. It heats, melts, and extrudes raw materials—such as polyethylene and polypropylene—into formed strips, and combines precise temperature control, traction, and winding technology to continuously produce high-strength, uniformly consistent geogrid strips. This equipment is ideal for the industrial production of reinforcement materials used in roads, slopes, foundations, and other civil engineering applications.

Core Product Features:

  • Precision Extrusion System: Equipped with an SJ-75-30 single-screw extruder featuring a 38CrMoAlA alloy steel screw and a 30:1 length-to-diameter ratio, ensuring stable melting and high-quality extrusion.
  • Efficient Heating and Cooling System: Combines ceramic heating rings, air cooling, and internal water circulation for precise temperature control, enabling long-term continuous production.
  • Modular Die Head Design: Made of high-strength mold steel with a compact structure and easy replacement, ensuring consistent product dimensions.
  • Fully Automatic Traction Unit: Upper and lower pressure roller traction system with patterned rollers ensures smooth, slip-free strip movement.
  • Touchscreen HMI: Features a 7-inch Samkoon touchscreen for visualized operation and intelligent parameter control.
  • Dual-Station Winder: Supports high-speed winding up to 200 m/min with automatic reel switching for improved efficiency.
  • Smart Control System: Utilizes Schneider electrical components and Top-Drive frequency converters for stable, reliable performance with support for remote maintenance and upgrades.
