Technical Description
Layer Complexity From 3 to 9 layers for pipes, films, sheets with versatile barrier/composite designs Materials & Barriers Incorporates EVOH, PA, PE‑RT, aluminum foil, UV barrier and more Automation & Precision Real-time thickness control, melt pumps, dosing systems, predictive maintenance Energy Efficiency Reduced power consumption, optimized cooling and calor control Application Diversity Food/medical packaging, underfloor heating pipes, automotive, technical sheets Cutting-Edge Advances in Co‑Extrusion for Reinforced Multi‑Layer Structures 1. High-Performance 5‑Layer PE‑RT Pipe Extrusion Outstanding speed & quality: The new line achieves up to 70 m/min, producing 5-layer PE‑RT pipes with oxygen barrier layers and exceptional surface quality and layer uniformity. Helical mandrel die design: Circular distributors reduce melt residence time, enable fast color/material changes, and maintain layer consistency. The system is modular, customizable (e.g., color striping, coatings, centering) and achieves outputs near 500 kg/h 2. Recycled-Material Co‑Extrusion Profiles Eco-efficient profiles: Their LAYER.COEX plus technology supports 55–65% mixed regrind in profile extrusion, delivering up to 18% cost savings, while preserving reliability and performance 3. Sustainable Multi‑Layer Pipe Heads Full recyclate compatibility: New PVC multilayer pipe heads can process up to 100% recycled PVC, irrespective of material quality, with flexible layer structures and optimized flow to eliminate visual defects. Smart controls: Employs the ppC (pioneer processControl) system for intuitive operator experience, seamless integration with MES/DCS, and lays groundwork for near–lights-out manufacturing 4. Ultra‑Fast Composite Pipe Lines Speed milestone: Achieved a new record extrusion speed of 80 m/min for composite pipes—significantly higher than previous benchmarks. Integrated controls: Line features unified user interface, quick-change tooling, compact layout, and full Industry 4.0 readiness 5. High-Efficiency HDPE Multi‑Layer Pipe Lines Energy & output boost: Offers 35% energy savings and more than double production efficiency. Supports 2- to multi-layer HDPE/PP pipes with adjustable layer thickness. Technical highlights: Synchronized extruder control, spiral multi‑layer die for uniform distribution, and centralized PLC ensuring precision 6. WPC Co‑Extrusion for Decorative Decking Aesthetic layering: Enables wood‑plastic composites with multi‑layered wood-grain textures. Achieved via specialized molds, masterbatch-enhanced layers, and precision parameter control to mimic natural wood textures. Texture control: Mold design and process tuning—like reducing speed or embossing—produce vivid, realistic surface finishes
