JWELL High-Efficiency Three-Layer PVC Solid Wall Pipe Co-Extrusion Machine is designed for the precision manufacturing of multi-functional solid-wall PVC pipes used across urban infrastructure, industrial conduit systems, and agricultural irrigation applications. With cutting-edge engineering and advanced polymer processing capabilities, this machine delivers robust performance, superior pipe quality, and versatile production to meet the increasing demands of modern piping systems.
This machine adopts two or more SJZ series conical twin-screw extruders to enable the co-extrusion of three distinct PVC layers into a solid-wall pipe. The inner and outer layers are composed of standard rigid PVC, while the middle (sandwich) layer incorporates either high-calcium PVC or a lightweight PVC foam material. This multilayer structure optimizes cost-performance, improves rigidity, and reduces the pipe's overall weight while maintaining mechanical strength and longevity.
JWELL's PVC solid-wall pipe extrusion machine is ideal for manufacturing pipes used in:
Urban drainage systems
Underground cable protection
Residential and industrial plumbing
Agricultural irrigation
Building infrastructure and ducting
Ventilation systems
Chemical pipelines
Construction projects requiring corrosion-resistant piping
Sewage and wastewater lines
Municipal engineering projects
1. Superior Extrusion System
Uses two or more SJZ series conical twin-screw extruders, ensuring efficient and stable co-extrusion of triple-layered pipes.
Screws and barrels are made of super wear-resistant alloy, offering durability and a long service life even under high-load operation.
Equipped with high-precision twin-screw volumetric feeders, ensuring uniform powder feeding without bridging.
2. Advanced Mold and Die Design
Optimized PVC triple-layer die head with chrome-plated, mirror-polished internal flow channels ensures excellent melt flow and layer bonding.
The die system offers excellent corrosion and abrasion resistance, critical for long-term stability and product consistency.
Specially designed sizing sleeves enable fast pipe cooling and diameter stabilization, allowing high-speed production with excellent pipe wall thickness control.
3. Intelligent Cutting System
Features a rotary clamping cutting machine that adapts automatically to different pipe diameters, eliminating the need for manual fixture changes.
Includes a new adjustable floating chamfering unit, allowing users to control chamfer size based on pipe diameter and wall thickness.
Cutting and chamfering are completed in one continuous step, boosting efficiency and ensuring clean pipe ends.
Integrated sealed dust extraction system improves chip collection and keeps the workspace clean and safe.
4. Enhanced Efficiency & Cost Savings
The sandwich layer design allows the use of recycled or foamed materials, significantly reducing raw material costs.
Co-extrusion ensures excellent bonding between layers and eliminates delamination or splitting, even under pressure or long-term usage.
High-speed production capability boosts throughput and lowers production cost per meter.
5. Automation & Control
Available with PLC centralized control system with touch screen interface for simplified operation and real-time parameter monitoring.
Modular control structure allows easy upgrades and integration with factory MES or ERP systems.
Temperature, pressure, extrusion speed, and layer thickness are automatically monitored and adjusted for consistent quality.
