Twin-Screw PET/PLA Sheet Extruder

The PET Twin-Screw Co-Extruded Sheet Production Line features an innovative parallel twin-screw mixing extruder system that ensures superior performance for PET processing. This advanced system includes hunger feeding, high-efficiency mixing, de-swinging exhaust, and self-cleaning capabilities for stable extrusion. The optimized vacuum exhaust system eliminates the need for a raw material crystallization drying system, though adding a crystallization drying device can further enhance the competitiveness of the sheet product. This versatile production line is perfect for manufacturing APET sheets, PETG sheets, CPET sheets, and PLA sheets, making it an ideal choice for various PET sheet extruder applications.
