LFT-G Long-Fiber Reinforce Thermoplastic Granules production line for fiber coating with polymer

Product Description

LFT-G production line is refer to continuous glass fiber or carbon fiber is fully dipped by the hot molten

thermoplastic resin,then be pulled out into rod or strip from shaping mould head,and be cut into different length (usually

10mm~25mm) pellets. Different from the traditional production method of short fiber reinforced material, it

produces long glass fiber reinforced material, for the glass fiber does not pass the mixing process, the fiber will not be

cut short, so the length of the fiber can be as same as the length of the cut particles, which can be reached the maximum

length. By the appropriate injection molding process of glass fiber ,length can be maintained 3~5mm length (and common

short fiber reinforced plastic injection products in the glass fiber length is generally only 0.2mm~0.7mm). Long glass fiber

reinforced plastic has a higher impact strength than short fiber reinforced material, which is more rigid, and the shrinkage

rate is smaller, and the deformation is small.

Application

Fiber, reinforced PP,PAPE,PBT,PC,ABS,PPS,POM,etc.

Technical data

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.
