Special screw structure, efficient plasticization with different formulations;

Flexible use of cone double or flat double extruders for pipelines with different pressure levels and calcium carbonate conditions;

The spiral mold reduces the number of weld seams on the pipeline, and the high compression ratio ensures high density and good mechanical properties of the pipeline

Use efficient single or double chamber vacuum boxes and cooling water tanks;

Adopting servo/variable frequency speed regulation and independent multi track structure traction to ensure uniform pipeline traction without deformation;

The planetary knife adopts both mechanical and hydraulic feeding methods for synchronous cutting
