Co-Extrusion Extruder

High-Precision, 360° Adjustable Multi-Layer Solution

Overview

Engineered for modern plastics processing, our co-extrusion extruder delivers high-precision multilayer profiles, films, and sheets with a unique 360° adjustable die/adapter system. It ensures uniform layer distribution, fast product changeovers, and superior material compatibility—driving innovation, quality, and market competitiveness.

Product Features

360° Adjustable Die System

• Full-angle adjustment of the co-extrusion head for perfect layer concentricity and edge alignment.
• Rapid fine-tuning reduces scrap, optimizes thickness uniformity, and stabilizes melt flow.
• Ideal for complex profiles, multi-channel ducts, and high-clarity multilayer films.

Multilayer Flexibility and Material Compatibility

• Supports 2–7 layers with independent melt channels for PP, PE, ABS, PC, PMMA, PETG, TPU, TPE, PA, EVOH, recycled blends, and functional tie layers.
• Smart flow balancing and rheology-matched spirals improve adhesion between dissimilar polymers.

Advanced Process Control

• Closed-loop control for pressure, temperature, and screw torque with high-speed I/O.
• Automatic thickness control (ATC) and gravimetric dosing ensure stable layer ratios (±1–2%).
• Real-time SPC dashboard with alarm diagnostics and recipe management.

High-Throughput, Energy-Efficient Design

• Barrier or mixing screw options for high output and low melt temperature.
• Servo-driven haul-off and high-efficiency barrel heaters cut energy consumption by 10–20%.
• Optimized thermal profile reduces gels and improves optical clarity in transparent structures.

Rapid Changeover and Low Maintenance

• Tool-less die lips and quick-clean adapters shorten downtime.
• Wear-resistant bimetallic barrels and nitrided screws extend service life.
• Modular co-ex lines scale from lab/R&D to high-volume production.

Application Fields

Building & Construction

• Multilayer window profiles, siding, decking, weatherable caps, sound-dampening pipes, cable conduits, waterproof membranes, and roofing films.

Furniture & Interior

• Co-extruded decorative profiles, ASA/PMMA capping for UV resistance, edge bands, skirting boards, and surface protection films.

Automotive & Transportation

• Lightweight trim profiles, multilayer ducts and tubes, interior panels, acoustic barriers, and protective laminates.

Packaging & Consumer Goods

• Barrier films (EVOH layers), multilayer sheets for thermoforming, peelable lidding, and scratch-resistant protective layers.

Electrical & Industrial

• Wire/cable jacketing with co-ex insulation layers, chemical-resistant linings, and reinforced structural profiles.
