Why the injection geogrid line is the industry choice
24 heads for high-speed production. Each head independently controlled.
Mitsubishi PLC ensures accurate positioning and repeatable weld quality.
Supports steel-plastic composite strips and PP strips.
10,000+ m2/24h with node strength at 90% of parent material.
Ultrasonic heating consumes less energy than thermal welding.
Ideal for PET geogrids where ultrasonic welding causes fiber damage. Zero fiber degradation at node points.
Where the injection geogrid line is used
Biaxial geogrids for road base reinforcement, extending pavement life and improving load distribution.
High-strength geogrids for retaining walls, steep slopes, and embankment stabilization.
Geogrid reinforcement for ports, railways, airports, and industrial yard construction.
Common technical and commercial questions from geogrid producers
An injection molded geogrid machine produces biaxial geogrid by injection molding locking nodes onto stretched PP or PET strips. The nodes mechanically lock the strips instead of welding them.
Injection molded nodes keep node strength close to the parent strip and avoid fibre damage in PET geogrid. Ultrasonic welding is faster and lower cost for PP geogrid. Many producers run both lines.
6 m working width, adjustable node pitch from 50 mm to 200 mm, and output of more than 10,000 m2 per 24 hours.
PP and PET strip, including recycled material when filtration is adequate.
Node strength typically reaches about 90 percent of the parent strip strength, which is the main advantage over welded nodes on PET geogrid.
Quotation depends on working width, injection head count and automation level. Send your specification and CDXLT will reply within 24 hours.
