Parameter Adaptability
- Model: HPJX-CPE-01 (modular design, compatible with single/double-wall corrugated pipe production)
- Applicable Materials: Rigid polymers (PVC, HDPE, PP) and flexible compounds (TPU, TPE, EVA), covering scenarios like building drainage and automotive wire harness protection
- Pipe Diameter Range:
- Single-wall: 10–50 mm (micro cable conduits)
- Double-wall: 16–63 mm (municipal drainage pipes)
Performance Advantages
- Tiered Output: 150/300/500 kg/h (screw diameters: 60/75/90 mm), adaptable to varied capacity needs
- High-Speed Production: Up to 30 m/min for HDPE double-wall pipes with corrugation forming modules.
II. Core Components & Technological Innovations
Extrusion System
- Screw Design:
- 60mm Screw (L/D ratio 25:1): Optimized for high-viscosity materials (e.g., TPU) at low-speed, high-torque extrusion (15–40 rpm).
- 90mm Screw (L/D ratio 30:1): Suited for HDPE high-speed extrusion (50–90 rpm), featuring double-threaded flights in compression zone for enhanced mixing.
- Temperature Control: 4–6 independent zones (±1°C precision), e.g., gradient cooling for PVC (185°C feeding → 165°C die).
Corrugation Forming Unit
- Modular Molds: Quick-change corrugation modules (tooth/sine wave profiles), precision ±0.2 mm.
- Vacuum Adsorption:
- Single-wall: Negative pressure forming (-0.08 MPa vacuum).
- Double-wall: Combined with internal pressure blow molding (0.3–0.5 MPa).
Cooling & Calibration System
- Three-Stage Cooling:
- Spray pre-cooling (15–20°C water)
- Vacuum calibration (8m SUS304 water tank)
- Air-knife drying (compressed air dewatering).
III. Material & Process Optimization
Material-Specific Adaptation
- HDPE Double-Wall Pipes: Single-screw + melt gear pump (pressure fluctuation <5%), paired with 22kW drive motor.
- TPU Flexible Pipes: Bimetallic barrel (250°C resistance) + forced feeder to prevent material slippage.
Production Process
- Preprocessing: Dehumidification drying (dew point -40°C, HDPE moisture ≤0.02%).
- Co-Extrusion: Supports dual-color/dual-material (e.g., UV-resistant PP outer layer + conductive TPE inner layer).
- Online QC: Laser micrometer (0.02 mm precision) + IR thermal imager for real-time corrugation pitch monitoring.
IV. Typical Applications & Configuration Advice
Application | Recommended Configuration | Key Technical Indicators |
---|---|---|
Building Drainage | 75mm screw + 300kg/h mode | Ring stiffness ≥8 kN/m² |
Automotive Vent Ducts | 60mm screw + TPU-dedicated die | Temp. resistance: -40°C~120°C |
Farm Irrigation Pipes | 90mm screw + double-wall co-extrusion | Burst pressure ≥0.6 MPa |
V. Smart & Energy-Saving Design
Intelligent Control
- HMI Interface: Stores 50+ process recipes, enables PLC-synchronized control between corrugator and haul-off (speed sync error ≤0.1%).
- Remote Monitoring: IoT-enabled data upload to MES for real-time production analytics.
Energy Efficiency
- Electromagnetic Heating: 40% lower energy vs. resistive heating.
- Waste Heat Recovery: Recycles cooling water for raw material pre-drying.
Conclusion
The HPJX-CPE-01 achieves full-spectrum production from micro flexible conduits to large drainage pipes through multi-tier screw configurations, modular corrugation forming, and precision temperature control. Its 500 kg/h max. output meets municipal project demands, while the 30:1 L/D screw ensures uniform plasticization for high-MFI polymers like TPU. For optimal configuration, prioritize servo-driven systems based on material properties (e.g., melt flow index) and corrugation complexity.
