Twin screw extruder line for 30% glass fiber reinforced with flame
retardant PA66/PA6
Product Description
The extruder line is special for producing 30% glass fiber reinforced with flame retardant PA66/PA6/PBT .For the high torque, it has
higher output and lower temperature than other low torque
extruders.And uniform screw clearance enables uniform despersion,
with retaining fibre length.

Our advantages
1. 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.
2. 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.
3. Advanced design
High torque: carrying capacity factor of gearbox up to 15Nm/cm3;
High speed: max. 1800rpm/m；
4. 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)；
5. Custom made design
Wide D/d choice:1.33～2.0;
Custom made clearance: minimum clearance can be 0.15mm；
Parts and advantages
| 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. |
