PET sheet extrusion line

The PET sheet twin-screw exhaust line (free from dry and crystallization) : Gwell launched PET sheet twin-screw exhaust line without drying and crystallization which has the advantages of low energy consumption, high efficiency.This machine is Gwell\'s 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.

4. PET sheet planetary multi-screw exhaust production line (free from crystallization and drying) : the planetary screw extruder is adopted as the main machine to increase the space for materials and air, and with the vacuum pumping system newly developed by Gwell can meet the needs of customers with large output and high quality sheets.
