ntroduction:

1. Using high-efficiency extruder designed for special PE, PP, PPR, PRET pipes. The screw adopts a structure with a barrier and a mixing head. The barrel adopts a new type of slotting machine barrel. The plasticizing and mixing effects are good, and the extrusion volume is large and very stable.
2. The line adopts spiral die head that designed for PE, PP, PPR, PRET large-diameter thick-walled pipe. The die has the characteristics of low melt temperature, good mixing performance, low cavity pressure, and stable production.
3. The line uses a proprietary technology of sizing and cooling system, using water film lubrication and water ring cooling to meet the requirements of PE, PP, PPR, PRETmaterials, to ensure high-speed production of thick-walled pipes with stable diameter and roundness.
4. The line adopts specially designed vacuum calibration tank with multi-stage control vacuum degree to ensure the dimensional stability and roundness of PE, PP, PPR, PRET pipes. Extruder and Hauling-off machine adopt imported brand-name governor to control with good stability, high precision and high reliability.
5. The operation and time of the line is controlled by the PLC programmatically with good man-machine interface. All process parameters can be set and displayed through the touch screen. Special extruder for marking line can be assembled to produce national standards pipes with color marking.
