HDPE Silicon Core Tube Production Line - Product Brief
Product Overview
The HDPE Silicon Core Tube Production Line is an advanced, automated system engineered to manufacture high-density polyethylene (HDPE) tubes with integrated silicon inner layers. These tubes are critical for protecting fiber optic cables in telecommunications, ensuring smooth installation and long-term performance. The line combines precision co-extrusion technology, intelligent controls, and energy-efficient design to deliver consistent quality and compliance with global standards (ITU-T, ISO).
Key Features & Technical Highlights
Co-Extrusion System
Dual-Layer Extrusion: Simultaneously extrudes HDPE outer layer and silicone inner core for seamless bonding.
Screw Configuration: 30:1 L/D ratio screws with anti-clogging design, suitable for HDPE and silicone materials.
Output Capacity: 150–600 kg/h (adjustable for tube diameters: 20 mm – 63 mm).
Cooling & Calibration
Vacuum Calibration: Ensures precise dimensional accuracy (OD tolerance: ±0.1 mm).
Spray Cooling: 3–5-stage closed-loop water cooling for rapid, uniform solidification.
Automation & Control
PLC + Touchscreen HMI: Real-time monitoring of extrusion speed, temperature, and tension.
Servo-Driven Haul-Off: Speed range 1–10 m/min, synchronized with extrusion for minimal material waste.
Cutting & Winding
Laser Length Control: Automatic cutting (1–6 meters) with ±1 mm precision.
Motorized Coiling: Optional coiling system for compact storage and transport.
