Production Line Overview
The line utilizes either parallel or conical twin-screw extruders (selected based on material and profile requirements), combined with high-precision vacuum calibration, haul-off, cutting, and stacking systems. This ensures dimensional stability, smooth surfaces, and high strength in finished products to meet diverse application needs.
Core Equipment Components and Technical Advantages
Extruder (Main Unit)
Screw Type Options:
• Conical Twin-Screw: Ideal for PVC WPC profiles, offering high torque and superior mixing performance, suitable for high wood-flour filling (40%-70%).
• Parallel Twin-screw: Designed for PE/PP WPC profiles with controllable shear force, perfect for micro-foaming and high surface-quality products.
Drive System:
• Variable frequency/servo motor with wide speed range (1:10) to accommodate different materials and output requirements.
• High-precision gearbox ensures smooth operation and low noise.
Temperature Control System:
• PID multi-zone temperature control (±1°C) guarantees melt uniformity.
• Optional air/water cooling systems for diverse plastic processing needs.
Wear-Resistant Design:
• Bimetallic/nitrided screws and barrels extend service life for high wood-flour formulations.
Vacuum Calibration Table
• Multi-stage Vacuum Adsorption: High-efficiency vacuum pumps ensure dimensional stability and bubble-free surfaces.
• Water Circulation Cooling: High-flow cooling system enables rapid shaping and boosts productivity.
• Modular Design: Customizable length (6-12m) to fit various profile cross-sections (e.g., door/window frames, decorative moldings).
Haul-off Machine
• Track/Clamp-Type Haul-off:
- Variable frequency drive + precision gear motor delivers strong traction without slippage.
- Adaptive pressure adjustment prevents profile deformation.
• Synchronized Control: Interlocked with extruder speed to minimize dimensional deviations.
Cutting Machine
• Servo-Driven Cutting:
- Cutting accuracy ≤±0.5mm with smooth, burr-free edges.
- Supports preset-length or manual cutting modes.
• Automatic Stacking: Optional flip-type or push-type stacking systems to reduce manual handling.
Turning Platform / Stacking System
• Auto-Turning: Designed for irregular profiles (e.g., window/door frames) to avoid manual damage.
• Cushion Protection: Wear-resistant rubber/silicone contact surfaces prevent scratches.
Control System
Intelligent Control:
• Premium control system with integrated touchscreen HMI (Human-Machine Interface).
• Real-time monitoring of key parameters: temperature, speed, vacuum level, cutting length, etc.
Data Logging & Alarms:
• Production data recording with process parameter storage/recall function.
• Overload protection, emergency stop, and fault alarm systems to minimize scrap rate.
