Polytek co-rotating twin-screw extruders are designed for maximum reliability, ease-of-use and flexibility. We offer turn-key solution for all types of material compounding applications.
we are proud to introduce our PTH series extruder which equiped with high torque and high speed gear box, desinged with specific torque of
12Nm/cm3 to achieve high screw filling rate, which results in a decrease of melt temperature, thus improving compound quality.
what is twin screw extruder
Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a "∞" shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .
Polytek also have two stage extruder for PVC compound and high filler masterbatch extrusion.

construction: Polytek Machine PET recycling, complete solution from washing till pelletizing for high quality product.
PET waste bottles recycling and washing system is a complete solution designed for bottles, such as water bottles, cola bottles, etc. label-removing, crushing, washing, drying and packing. It is the perfect system to process the waste bottles into PET flflakes, which can present high quality performance of recycled PET flflakes. Because of the venting and vacuum design of twin screw extruder, the IV drop of PET will be controlled well.
To avoid the strand breaks, underwater strand pelletizing system will convey the strands to pelletizer automatically (optional).
