Installed above the extruder feed port, the system uses PID closed-loop control to hold the weight per meter and to adjust screw speed, haul-off speed and feed rate in real time. It is equipped with a Siemens S7-1200 PLC and touch screen for intuitive operation and easy service.
Full inspection instead of sampling Real-time monitoring of weight per meter, outer diameter and output, with full traceability.
1%–5% material saving Precise extrusion control and less scrap from weight deviation.
Fits new and existing lines Compatible with all extruders, haul-off and take-up units, with no major modification.
