Why the PP strip extrusion 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.
5,000-15,000 m2/day with node strength at 90% of parent material.
Ultrasonic heating consumes less energy than thermal welding.
38CrMoAlA nitrided screw with HV≥740 hardness ensures long service life. ZLYJ280-16 gearbox for reliable power transmission.
Where the PP strip extrusion line is used
Reinforcing weak soils for road and railway embankments.
Preventing landslides and erosion on steep slopes.
Base reinforcement for highways, railways, and ports.
Common technical and commercial questions from geogrid producers
A PP strap extrusion line produces polypropylene strap, the raw material used for geogrid production, woven bags and packing strap.
Our standard PP strap extrusion line uses a 140 mm screw and delivers 5-8 tons per day, with 4 to 6 die heads depending on strap width.
Yes, with a PET crystallizer and dryer plus a modified screw and die design.
The extrusion process is the same, but geogrid strip requires tighter width and thickness tolerance plus higher tensile strength.
Price depends on output, number of die heads and whether downstream stretching and winding are included. Send your requirement for a quotation.
