Four Technologies. One Mission.

Each solves a different node connection challenge. Together they cover the entire geosynthetics spectrum.

🧪
Proven 路 In Production

Ultrasonic Geogrid Welding

High-speed ultrasonic node welding for PP and steel-plastic geogrids. 24-48 heads, 15/20kHz dual frequency, 6m working width. The industry standard for high-volume production.

15-20kHz 路 24-48 heads 路 6m width 路 10,000-25,000 m²/day

🌀
Advanced 路 Fiber-Safe

Vibration Friction Welding

Motor-driven linear vibration friction welding for fiberglass, PET, and FRP geogrids. Preserves fiber integrity where vertical ultrasonic damages it. 6m weld width, 100-210 m²/h.

100-200Hz 路 6m width 路 JT/T 1432.1-2022 路 Fiber-safe nodes

🔩
Proven 路 In Production

Geocell Ultrasonic Welding

Complete geocell production line: HDPE extrusion + ultrasonic welding. 16 heads weld 8m wide. From pellets to finished panels in one automated process. Cell height and thickness customizable.

16 heads 路 8m weld width 路 Ø210 extruder 路 200-300 kg/h

🏭
R&D 路 Coming Next

Injection-Molded Locking Nodes

📜 Download White Paper

The next generation: mechanical locking + plastic injection replaces welding entirely. Node strength independent of material weldability. Opens PET, aramid, basalt, and hybrid geogrids to mass production.

In development 路 Multi-material compatible 路 Mechanical + fusion bond
