High-Performance Double Wall Corrugated Pipe Extrusion Lines – China Suppliers & Factory for PE, PP, PVC
Machine Parameters
High-Speed Single-Screw Extrusion Line (For PE/PP Pipes)
A newly designed, closed molding machine with a special high-efficiency cooling system for forming aluminum modules dramatically improves cooling rates, shortening cycle times for higher throughput.
Paired with a professionally designed corrugated pipe die, it enables large-scale, stable extrusion for demanding continuous production.
Forming modules are made from precision-cast LY12 high-grade aviation aluminum (copper content ≥5%), ensuring high density, no porosity, and resistance to long-term deformation. Modules offer excellent interchangeability and customizable waveform designs.
Features an automatic DWC cutter with computer control for accurate cut length, stable operation, and easy use.

Conical Twin-Screw Extrusion Line (For FRPP/PVC Pipes)
The line's overall energy consumption is low. The conical twin-screw extruder offers higher conveying efficiency than single-screw models with lower installed power, enabling truly economical operation.
Capable of processing powder formulas directly (e.g., raw material + calcium carbonate), eliminating the need for pelletizing to significantly reduce raw material costs while enhancing pipe ring stiffness.
Equipped with a vacuum venting device to effectively remove moisture and air, preventing bubbles in the pipe wall for a dense, smooth interior and exterior surface.

| JWSBL-1200 | 800-1200 | 1400 | 1400 | 1.5 |
Parallel Twin-Screw Extrusion Line (For HDPE/PP Pipes)
Utilizes two parallel co-rotating twin-screw extruders for superior dispersion. Can process both powder and granular raw materials simultaneously without pre-compounding, offering maximum formula flexibility.
Includes a side-feeding system allowing for real-time online adjustment of filler ratios (e.g., calcium powder), facilitating quick and convenient formula changes.
The building-block style screw and barrel assembly simplifies maintenance and part replacement, minimizing downtime.

Horizontal DWC Pipe Line (For Small-Diameter Pipes)
Specifically designed for producing small-diameter DWC pipes (Ø50-250mm), ideal for drainage, venting, and conduit applications.
Incorporates a new high-efficiency single-screw extruder that delivers greatly enhanced plasticizing capacity and high output of flexible pipe products.
The horizontal structure of the molding machine provides a compact footprint and facilitates easier operation and maintenance.
