Adopt screw design with large 40 L/D ratio to achieve high output and energy saving. The extruder can be integrated with online gravimetric doser for masterbatch, also can produce single layer and multi-layer PPR pipes. The position of co-extruder adopts back-type structure to save space.

Single or multiple spiral die head structure can be selected for single layer or multi-layer structure, with uniform wall thickness, sleeve structure is adopted for setting die, forced water-cooling at inlet, high-speed and stable.

Double-station independent control, vacuum adopts negative pressure closed-loop automatic adjustment of vacuum degree, improves pipe production quality, reduces noise by more than 30dB, and saves energy by 40-90%.

Each station is controlled independently. The haul-off unit adopts permanent magnet synchronous motor and high-speed hauling belt to ensure a stable speed regulation range of more than 50 times and realized high speed production.

Rotary swarfless cutter or flying knife swarfless cutter for option, precised cutting length control.

The whole series of online auto packing device realized on line auto bundling and bagging, on line weighing system before bundling ensured the quality of pipe before packing, greatly improve efficiency and reduce labor investment.
