Why Composite Pipe Production Matters
Composite pipes produced by this machine combine the advantages of both plastic and metal:
Strong aluminum core for rigidity and dimensional stability
Plastic (PEX/PPR) layers for corrosion resistance, flexibility, and hygiene
Excellent bonding integrity between layers due to one‑step co‑extrusion
High pressure tolerance, heat resistance and long service life
This construction significantly improves performance over traditional single‑material pipes, making it ideal for residential, commercial and industrial applications.
Key Features & Benefits
✔ Efficient One‑Step Co‑Extrusion
This production line forms all five layers in a single extrusion process, improving adhesion strength and reducing production time, footprint and labor costs.
✔ High‑Quality Aluminum Welding
The aluminum layer is formed and welded using ultrasonic overlap welding, providing a tight, even seam and enhanced structural reliability in the finished pipe.
✔ PLC & Automated Control System
The extrusion line integrates centralized PLC control with human‑machine interface for easy operation, stable processing and reliable production quality.
✔ Flexible Production Capabilities
Supports different pipe diameters and materials (PEX, PE, PPR, PERT), and can be adjusted for varied production speed and output.
✔ High Production Yield
Advanced design and optimized extruder components enable high efficiency and reduced waste, with typical production yields reaching up to ~98%.
Production Line Workflow
The extrusion line is engineered as a cohesive system, with each section optimized for precision and stability:
Raw Material Feeding & Extrusion: Single‑screw or co‑extruder melts and plasticizes materials for consistent output.
Aluminum Forming & Welding: Aluminum strip is formed into a tube and welded with ultrasonic or overlap technology.
Co‑Extrusion of Layers: Inner plastic layer, adhesive and outer plastic layer are co‑extruded around the welded aluminum tube.
Cooling & Calibration: Pipes are cooled through controlled water tanks and sized for dimensional accuracy.
Haul‑Off & Cutting/Winding: Finished pipe is pulled off, cut to length or wound into coils for packaging.
