Jwell delivered a complete PP geogrid board extrusion line to a major geosynthetics manufacturer in the United States. The dual-extruder JWS200+JWS200 configuration produces wide-format PP boards that serve as the base material for punched-and-drawn geogrid manufacturing — a critical reinforcement component in road base stabilization, slope protection, retaining wall reinforcement, and soft soil foundation treatment across U.S. infrastructure projects.
Technical Specifications
Key Features
✓ Dual Single-Screw Extruder JWS200+JWS200
Two JWS200 extruders operating in parallel deliver a combined 1,500 kg/h output with superior melt homogeneity. Purpose-built screw geometry for PP processing ensures low shear heat buildup and consistent polymer orientation — critical for downstream geogrid punching and stretching performance.
✓ Precision T-Die & 3-Roll Calender
Wide-width adjustable-lip T-die paired with a three-roll vertical calender maintains board thickness tolerance of ±0.15 mm across the full 2,000 mm width. Uniform thickness distribution is essential for consistent geogrid node strength after the punching-and-drawing process.
✓ Multi-Zone Temperature Control
Independent PID-controlled barrel and die zone heating maintains the optimal PP processing window. Prevents thermal degradation and ensures consistent crystallinity — a key factor in geogrid tensile modulus and long-term creep resistance under soil loading conditions.
✓ Fully Integrated Siemens PLC Control
Synchronized line speed control from extrusion through calendering, cooling, edge trimming, and stacking. Real-time monitoring dashboard with recipe storage enables rapid product changeover between different geogrid board thickness specifications.
✓ Automatic Flying Saw & Stacker
High-speed cross-cut saw synchronized with line speed for precise board length cutting. Automatic stacking system with edge protection ensures efficient downstream handling — boards are ready for direct transfer to the geogrid punching line without re-handling.
✓ USA-Ready Service & Compliance
Electrical configuration adapted to U.S. 460V/60Hz/3-phase standard. Jwell’s North America service infrastructure provides on-site installation, commissioning, and comprehensive operator training. Spare parts available from regional stock with 24-hour dispatch capability. Documentation packages support AASHTO M 288 geogrid compliance testing workflows.
Customer Feedback
“The dual-extruder configuration gives us exactly the throughput we needed — 1,500 kg/h with board flatness that translates directly to uniform geogrid tensile strength after our punching process. Jwell’s commissioning team understood U.S. infrastructure standards from day one, and their PLC recipe system lets us switch between 3 mm and 8 mm base boards in under 15 minutes. This line is now the backbone of our geogrid production.”
