Twin Screw Compounding Extruder for PPA PPS PEEK with GF | CF | Precious Plastic Recycling Extruder

Our HPL series twin screw extruders are specially developed for pelletizing production of high-temperature special engineering plastics. Equipped with high-torque transmission system, this machine features larger throughput and more stable temperature control compared with conventional low-torque extruders. It is the ideal processing equipment for compounding PPA, PPS, PEEK and other engineering plastics reinforced with glass fiber (GF) and carbon fiber (CF).

Suitable for processing various high-performance special engineering plastics:

PEEK, PEI, PPS, PPSU, PA6T, PA9T, LCP and related modified materials

The throughput is 1 to 2 times higher than ordinary low-torque extruders of the same specification. The largest model can reach a maximum output of 12 tons per hour, greatly improving production efficiency.

Under the same output requirement, our small-size extruder can replace larger models from other brands. For example, HPL51 delivers higher output than traditional 65-type extruders, which effectively reduces equipment footprint, raw material consumption and overall operating cost.

We adopt heating rods instead of traditional cast copper heaters, achieving an energy saving rate of 15% to 20%.

• High torque performance: The load capacity factor of the gearbox reaches up to 15 Nm/cm³;
• High running speed: The maximum rotational speed can reach 1800 rpm.

The output shaft bearings are designed with no-load structure, which effectively protects the vulnerable bearing components and extends their service life. The overall designed service life of the gearbox is over 72,000 working hours (equivalent to 10 years of stable operation).

• Wide adjustable D/d ratio: Customizable range from 1.33 to 2.0;
• Adjustable screw barrel clearance: The minimum clearance can be customized to 0.15 mm to meet different material processing requirements.

Transmission gearbox		The most advanced structure: bilateral symmetry gear drive system; it’s the same with the gearbox of German Flanders, Austria EssenBas.Now, the first-line extruder manufacturers in the world, such as Corperion,Berstorff, Leistritz, Toshiba, JSW are using the transmission structure; servcie life of the gearbox≥72000hrs.
Screw element		Various kinds of function elements, mixing and dispersing elements developed by ourselves can provie flexible production for kinds of materials and production process. Optional material: W6Cr5Mo4V2, Ni-based alloy, HIP alloy,Co-based alloy.
Barrel		Barrels are equipped with integrated wear-resistant alloy steel liner, which has the same composition and wearing feacture with W&P .Our mirror polishing seamless barrels, surface finish Ra0.2, verticality between barrels inner hole≤0.015mm；linearity of ten assembled barrels≤0.05mm； Optional material: W6Cr5Mo4V2, Nitriding steel, Tool steel, Ni-based alloy, HIP alloy,Co-based alloy.
Torque limiter		Steel ball type safety clutch + torque limiter Made in Germany have the characteristics of accurate torque protection, high repeatability and quick reset.
Side feeder		Our CWJ series side feeder can be used to feed powders and short fibres, which can improve the output and reduce abrasion of scew and barrels. And segmented screws available. Barell with cooling function is available.

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.
