Twin Screw Extruder for PET / ABS

Extrusion granulation process generally uses a screw extruder to melt and extrude PET to form a strand, which is then cooled by water, sent to a pelletizer, and cut into cylindrical particles. When a twin-screw extruder is used, the PET material stays in the extruder for a relatively short time (less dead angle), and it is convenient to evacuate the residual water and reduce the hydrolysis of the PET material, which is advantageous for improving the quality of the pellets. Moreover, the output of the twin-screw extruder is high, so it is desirable to use a twin-screw extruder. At the same time, we provide non-stop screen changer to effectively filter impurities, to ensure the quality of recycled materials and machine efficiency.
