Engineered for unparalleled precision, our Biaxial Stretching GeoGrid Production Line fabricates PP/PE geogrids with superior tensile strength for roadways, soil stabilization, and infrastructure reinforcement. Featuring fully automatic, computerized control and deep-channel twin-screw extrusion, these grids deliver optimized load transfer, enhanced erosion resistance, and rot- and ageing-resistant durability.
Certified to CE, ISO 9001, and SGS standards, its twin-screw deep-channel extruder with 1 450–2 200 mm die-head widths delivers up to 300 double-direction geogrid sets per month, with high-strength, rot- and aging-resistant PP/PE output.
Our production line integrates three precision stages—sheet extrusion, mesh punching, and biaxial stretching—into a single, continuous flow:
1. Sheet Extrusion
Twin-screw, deep-channel screws melt and homogenize PP/PE into a uniform film.
2. Mesh Punching
Precision die-heads system produces 5 × 5 mm to 50 × 50 mm mesh patterns with quick-change tooling.
3. Biaxial Stretching
Single- and double-direction stretching optimizes tensile strength and dimensional stability.
By integrating these stages in a single, fully automatic computerized line, you get consistent grid geometry, repeatable mechanical properties, and maximum uptime—exactly as Tongjia specifies.
