18.5 kW Laboratory Twin-Screw Extruder (30 kg/h Output) for Compounding and Modification

The HPL27 laboratory twin-screw extruder is specifically engineered for laboratory process simulation, polymer compounding and material formulation development. It is equipped with two independently controlled side feeders, allowing simultaneous addition of multiple fillers, additives and masterbatches, which significantly enhances formulation flexibility and expands experimental scope.

This equipment features excellent process adaptability and outstanding energy efficiency. It supports seamless adjustment of all critical processing parameters including temperature profile, screw speed and feeding rate, ensuring precise control over material processing conditions. It is suitable for both research and development experiments in academic and industrial laboratories, as well as small-batch pilot production. The extruder can handle processing requirements for most common polymer materials and their composites.

• High output

  The output is 1-2 times larger than the same size extruder from other lower torque twin screw extruders.

  The biggest extruder can output up to 12T/h per set.

• Energy-saving

  For the same output , our small size extruder can replace the big size of other extruder, such as our HPL51 has more output than other 65 extruder , smaller extruder, less energy consumption,less material consumption, smaller production areas.

  And we use heat rod instead of cast copper heater, which can save 15%-20% energy.

• Advanced design

  High torque: carrying capacity factor of gearbox up to 15Nm/cm3;

  High speed: max. 1800rpm/m；

• Long service life

  bearings on output shaft 2 without load, which greatly extended the service life of the bearings on the weak axis , gearbox life can reach 72000 hours (10 years)；

• Custom made design

  Wide D/d choice:1.33～2.0;

  Custom made clearance: minimum clearance can be 0.15mm；

We are dedicate to develop, design, and manufacture co-rotation, counter-rotation parallel twin-screw extruder production line.Our extruders have the advantages of “high torque, high efficiency, low energy-consumption, high price/performance ratio, long service life " (designed service life of gearbox as long as 72000 hrs). We keep the same step with the most advanced extruder manufaturers in the world.

We can supply :Twin screw extruder production line;

High torque gearbox;Automatic long fiber reinforced thermoplastic composites (LFT - D) production line;Counter-rotation parallel twin screw extruder;Differential concentration mixer;
