High Torque Polymer Extruder Machine Twin Screw Design for Pilot Lines and Batch Production Applications

Technical datas

Application

• Fiber reinforcement: glass fiber, carbon fiber reinforced PP,PA,PBT,ABS,AS,PC,POM,PPS,PET,PPO,LCP,etc.
• Ploymer blending :PC+ABS, PA+ABS,CPE+ABS,PP+EPDM,PA+SBS,etc.
• Filled modification :PE,PP,EVA+CaCO3, talcum powder, titanium dioxide, carbon black and other inorganic filler.
• Special Engineering Plastics: PEEK,PEI,PPS,PPSU,PA6T,PA9T,LCP,etc.
• High Concentration Color Masterbatches: PE,ABS,PS,EVA,PET,PP etc. With high concentration of pigments and other additives.
• Masterbatches with Flame Retardants:PP,PA,ABS,EVA,PBT etc.with flame retardants and other additives.
• Special Functional Masterbatches :Masterbatches with anti-static,anti-abcteria ,or other special functional fillers.
• Masterbatches for Degradable Polymers:PP,PE,PS etc. Blended with high concentration of starch and other processing aids.

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.
