PEK PA66 Nylon with glass fiber twin screw extrusion granulation machine

PEK PA66 Nylon with glass fiber twin screw extrusion granulation machine

Device overview

Twin screw/double screw compounding extruder is specially designed for compounding PE (LLDPE, LDPE, HDPE), PP, PA6, PA66,PC, PEK,TPE and Copolymers such as SBS,Color batches,Filler modified resin and additives ( UV protection Materials, Modified, EVA, black carbon granule, flame-retardant granule.

The machine has excellent mixing performance, good self-cleaning performance and flexible modular configuration characteristivs which make them suitable for processing different types of material.

Different kinds of side doser is used to feeder different kinds or types of material. There is also doser to weight the additives material to make up a prescription.

Extruder with Several Feeders

With special design of combination for screw and element, the plastic and additives will be well melted, plasticized and compounded. With the vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency. Then the final granules can be widely used in various fields. Each kinds of feeders can feed different material or additives,like granules and powders.

Side feeder

Different designed of doser or side feeders can feed all types of material, such as granules, powder and liquid or short glass fibers and long glass fibers. and doser with Mechanotronicas design, high accurately measure, stabillization feeding. Widely measure range.All process for material treatment is conducted in airproof environmenet, without rising dust.

gearbox for co-rating twin screw.jpg


Gearbox with Parallel tri-axial structure is combination of reduction and matrix. The gear is made of high quality alloy. It had been treated by cementation heat process, the precision grade can reach6th. It guarantees the tooth surface is high speed, overloading, low noise and high torque.

co-rating screw element.jpg


Screw & elements: W6Mo5Cr4V2 (6542#) high speed tool steel that had been treated by the vacuum hardening process with the hardness of the surface is HRC58-62.Molding through dedicated grinding machine. The cleanliness is much better than products out of traditional process.
