2. PET sheet single screw exhaust production line: This model only needs to crystallize PET, no need to dry. Its advantages: low energy consumption, simple process, easy maintenance of equipment, and can guarantee the absorption of 18CM deep cup.
3. PET sheet twin-screw exhaust production line (free of crystal drying): Gwell crystal-free, dry-free exhaust PET sheet unit has the advantages of low energy consumption and high efficiency. This model is Gwell Company. Continuous improvement of upgraded products, has made major technical upgrades to the core vacuum system, upgraded from the original Roots-water ring pump set to the Roots-rotary-spindle pump set, which can achieve a vacuum degree of ≤10Pa, while using PET The special alloy steel thin-walled roller group greatly improves the cooling efficiency, thereby increasing the yield and improving the toughness and transparency of the product. Jinwell's independently programmed operating system ensures that the device is user-friendly and easy to operate.
4. PET sheet planetary multi-screw exhaust production line (free crystal drying): the use of planetary screw extruder as the main machine, increasing the area of ??material and air, with the latest vacuum pumping system developed by Alloy Weir, Meet the needs of customers with large-volume, high-quality sheets.
