Line Process Flows:
Extruder —— Screen changer —— Melt pump —— T-Die —— Calender —— Thickness Scanner —— Cooling Bracket —— Cutting Knife —— Haul-off —— Winder
Extruder:
– Single-Screw or Twin-Screw Extruder: Melts and homogenizes the PETG material.
– Barrel and Screw: Designed for optimal mixing and melting of the material.
– Heating Elements: Maintain precise temperature control to ensure consistent material flow.
Screen Changer: Filters out impurities from the molten PETG.
Melt Pump:
-Ensures a consistent and controlled flow of the molten plastic to the die.
Calendering Unit:
– Three-Roll Calender: Comprises a series of heated and polished rollers that smooth and shape the sheet, controlling its thickness and surface finish.
– Gap Adjustment Mechanism: Ensures precise control of sheet thickness.
Cooling System:
– Cooling Rollers: Gradually cool the sheet to solidify it while maintaining its dimensional stability.
– Water Baths or Air Cooling Units: Further reduce the sheet’s temperature as needed.
Haul-Off Unit:
-Draw the sheet through the extrusion line at a controlled speed, ensuring uniform thickness and preventing stretching.
Winder:
-Collects the finished film onto rolls for easy handling, storage, and transport.
Main Process Overview:
(1). Feeding and Melting: Raw PETG pellets are fed into the extruder, where they are melted and homogenized by the rotating screw and heating elements.
(2). Filtering and Pumping: The molten PETG is filtered to remove impurities and then pumped to the die at a consistent flow rate. A double-gear metering pump is used to achieve the proper melt extrusion amount, ensuring uniform melt flow and pressure stability.
(3). Calendering: The hot sheet passes through a series of calender rollers, which smooth and shape it to the desired thickness and surface finish.
(4). Cooling: The sheet is gradually cooled using cooling rollers and possibly additional cooling units to solidify and stabilize its dimensions.
(5). Corona Treatment: The sheet undergoes corona treatment to increase its surface energy, improving adhesion for printing or coating.
(6). Rewinding: After trimming, the corona-treated film is rolled into a large, wide, and high-diameter master roll.
(7). Slitting: Using an unwinding machine, the wide master roll is cut into smaller rolls of the width and length specified in the order, making it convenient for transportation and further printing processes.
(8). Haul-Off: The sheet is drawn through the production line by pull rollers, ensuring consistent speed and tension.
(9). Winding: The finished film is wound onto rolls for storage and transportation, with tension control to ensure even winding.
