High-Performance Double Wall Corrugated Pipe Extrusion Lines for PE, PP & PVC

High-Speed Single-Screw Extrusion Line (For PE/PP Pipes)

Optimized Cooling & Molding: 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.

Stable High-Output Extrusion: Paired with a professionally designed corrugated pipe die, it enables large-scale, stable extrusion for demanding continuous production.

Durable & Customizable Modules: 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.

Precision Cutting: 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)

Energy-Efficient Production: 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.

Direct Powder Processing & Cost Savings: 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.

Superior Pipe Quality: 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.

Parallel Twin-Screw Extrusion Line (For HDPE/PP Pipes)

Excellent Mixing & Raw Material Flexibility: 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.

Online Formula Adjustment: Includes a side-feeding system allowing for real-time online adjustment of filler ratios (e.g., calcium powder), facilitating quick and convenient formula changes.

Modular & Easy Maintenance: The building-block style screw and barrel assembly simplifies maintenance and part replacement, minimizing downtime.

Horizontal DWC Pipe Line (For Small-Diameter Pipes)

Compact Solution for Small Pipes: Specifically designed for producing small-diameter DWC pipes (Ø50-250mm), ideal for drainage, venting, and conduit applications.

High Plasticization & Output: Incorporates a new high-efficiency single-screw extruder that delivers greatly enhanced plasticizing capacity and high output of flexible pipe products.

User-Friendly Operation: The horizontal structure of the molding machine provides a compact footprint and facilitates easier operation and maintenance.
