PE/PET Filler Masterbatch Twin Screw Extruder Machine 350kg/h Output

The HPL51 twin screw extruder pelletizing line is specifically engineered for high-efficiency filler masterbatch production. Its high-torque design delivers superior output capacity while maintaining lower processing temperatures compared to conventional low-torque extruders of equivalent size.

• Color Masterbatch: PE, PET
• Filler Masterbatch: PE, PET + CaCO₃
• Compatible Polymers: LDPE, LLDPE, HDPE, EVA, PVC, PP, PET, ABS, PC, PA

1. High Output Capacity

   Delivers 100-200% higher output than low-torque twin screw extruders of the same screw diameter. Our largest extruder model achieves a maximum output of 12 metric tons per hour.

2. Energy Efficiency

   Our compact high-torque design allows smaller machines to replace larger conventional extruders. For example, the HPL51 outperforms standard 65mm extruders in output, resulting in reduced energy consumption, lower material waste, and smaller factory footprint requirements.

   Additionally, our ceramic heating rod technology reduces energy consumption by 15-20% compared to traditional cast copper heaters.

3. Advanced Engineering Design
   • High torque density: Gearbox load capacity factor up to 15Nm/cm³
   • High speed capability: Maximum screw speed up to 600rpm (standard configuration)
4. Extended Service Life

   Unique bearing arrangement eliminates radial loads on the output shaft bearings, significantly extending the service life of critical bearing components. The gearbox has a designed service life of 72,000 operating hours.

5. Customization Capabilities
   • Wide OD/ID ratio range: 1.33 to 2.0
   • Customizable screw-barrel clearances: Minimum clearance down to 0.15mm
   • Tailored screw profiles for specific material formulations

We are dedicated to the development, design, and manufacturing of co-rotating and counter-rotating parallel twin screw extruder production lines. Our equipment is characterized by high torque, high efficiency, low energy consumption, excellent cost-performance ratio, and long service life.
