Classification of PET sheet extrusion production line:
1. Single screw production line for PET sheet: single screw extrusion production line for APET, PETG and CPET sheet is the most mature project with the most stable production at present. Generally, single extruder production line or twin-extruder production line is adopted and the latest technology to increase the general efficiency by 30%.
2. PET sheet single screw exhaust production line: this machine only needs to crystallize PET, and does not need to dry. Its advantages: low energy consumption, simple process, convenient equipment maintenance, and can ensure the blister 18CM deep cup.
3. The PET sheet twin-screw exhaust line (free from dry and crystallization) : It is launched PET sheet twin-screw exhaust line without drying and crystallization which has the advantages of low energy consumption, high efficiency.This machine is our continuous improvement upgraded products , and its central vacuum system has been upgraded. The original roots - water ring pump group upgrades to roots - rotary vane pump, which can make the vacuum degree reach 10 pa, or less. Meanwhile by using PET special alloy steel thin-wall roller unit can increase the cooling efficiency, so as to increase output, improve product toughness and transparency. Gwell's independently programmed operating system ensures that the device is user-friendly and easy to operate.
