PE PP Single Layer Sheet Extruder Machine Production Process
PE, scientifically known as polyethylene, is a type of plastic granules. The production process of PE PP Single Layer Sheet Extruder Machine includes a single-screw extruder, sheet die, three-roll calender, cooling support, traction machine, and winding machine. First, PE PP Single Layer Sheet Extruder Machine the plastic granules are fed into the drying hopper via a screw feeder. From there, they enter the screw barrel, which is equipped with a heating device. As the temperature rises, the granules melt. Under the induction of the screw, the material enters the sheet die. Under pressure, the sheet preform is produced from the die. The plastic preform enters the three-roll calender, where the temperature and gravity of the rollers shape the final product's thickness and gloss. The sheet is further cured by the cooling support, while a trimming device removes excess material. The finished product then passes through the traction machine. The speed of the traction machine is precisely matched to the speed of the extruder and the three rolls, making the entire production process more stable. After passing through the traction machine, the sheet enters the winding machine, where it is cut and wound to the appropriate length according to the customer's product requirements.
