1. High Production Throughput

   Our extruders deliver 1–2 times higher throughput than conventional low-torque twin screw extruders of the same size. The largest model achieves a maximum throughput of 12 t/h per unit.

2. Superior Energy Efficiency

   Under the same production capacity, our compact extruders can replace larger models from competitors. For example, our HPL51 delivers higher throughput than standard 65-type extruders, reducing energy consumption, raw material waste and factory floor space. Additionally, we use heating rods instead of traditional cast copper heaters, saving 15%–20% of energy consumption.

3. Advanced Structural Design

• High torque: Gearbox specific load capacity up to 15 N·m/cm³
• High speed: Maximum screw speed up to 1800 rpm

4. Extended Service Life

   The output shaft adopts an unloaded bearing design, which significantly extends the service life of bearings on the vulnerable shaft. Our gearboxes have a designed service life of 72,000 hours (equivalent to 10 years of normal operation).

5. Flexible Customization

• Wide D/d ratio range: 1.33～2.0
• Customizable screw clearance: Minimum clearance down to 0.15 mm

1. Supply a full range of extruder spare parts, including barrels, screw elements, screw shafts and related components.
   • Screw element diameter: 16–400 mm
   • Barrel inner diameter: 15.6–500 mm
2. Professional repair and replacement services for imported gearboxes, applicable to extruders with screw diameter ranging from 16 mm to 450 mm.
3. Provide maintenance and replacement for imported twin screw extruders, as well as overall production line optimization and upgrading solutions.
