High-Performance SJ120 Single-Screw Extrusion Line for PP, PE & ABS Profiles
1. Superior Performance & Precision Engineering
- Advanced Screw Design: Optimized SJ120 single-screw (120mm diameter) with a 36:1 length-to-diameter (L/D) ratio 4, ensuring exceptional plasticizing efficiency and uniform melt consistency for PP, PE, and ABS.
- Thermal Stability: Equipped with ceramic heating zones for precise temperature control (±1°C), critical for processing temperature-sensitive ABS and high-viscosity PE 4.
- Vacuum Calibration & Cooling: Integrated stainless-steel vacuum calibration system and multi-stage spray cooling ensure dimensional accuracy (±0.1mm) and minimal residual stress in profiles 12.
2. High Production Capacity & Efficiency
- Output Range: Capable of 450-600 kg/h production throughput for profiles up to 2,000mm width and 3-30mm thickness 34, adaptable to diverse industrial demands.
- Speed Flexibility: Variable-frequency drives enable extrusion speeds of 5-200 meters/minute, synchronized with downstream haul-off and cutting units 12.
- Rapid Material Changeover: Quick-cleaning barrel design reduces downtime between PP/PE/ABS transitions by 30% 4.
3. Key Competitive Advantages
- Multi-Material Versatility: Processes PP, PE, ABS, PS, and PVC profiles (e.g., architectural trim, automotive seals, industrial components) with minimal retrofitting 34.
- Energy Efficiency: Direct-drive motor system reduces power consumption by 25% versus conventional extruders, with actual operational load at ~70% of 310kW total capacity 34.
- Precision Cutting & Automation: Laser-guided rotary cutters achieve ±0.1mm length tolerance, paired with servo-driven haul-off for seamless integration into automated lines 1.
- Low-Maintenance Design: Hard-coated screws and nitride-treated barrels extend service life by 2-3×, backed by 1-year warranty and lifetime technical support 13.
4. Application-Specific Innovations
- Co-Extrusion Capability: Optional 2-3 layer co-extrusion heads for laminated profiles (e.g., UV-resistant ABS/PE composites) 1.
- Real-Time Quality Monitoring: IoT-enabled sensors track melt pressure, torque, and profile density, ensuring consistent output for critical applications like automotive or construction 4.
Why Choose the SJ120 Line?
Engineered for high-mix, high-volume profile manufacturing, this system merges German-grade precision with robust Chinese engineering. Its 550-600 kg/h output for PP/PE/ABS profiles-validated by industrial clients in automotive and building sectors-delivers 30% faster ROI through energy savings, minimal scrap, and 24/7 operational reliability. Ideal for Tier-1 suppliers transitioning to sustainable, high-tolerance polymers.
