1. Raw Material Handling and Feeding System:
- Hopper: Feeds raw PET pellets into the extrusion system.
- Dosing Units: Precisely measure and mix raw materials, including any additives or colorants.
2. Extruder:
- Single-Screw or Twin-Screw Extruder: Melts and homogenizes the PET material.
- Barrel and Screw: Designed for optimal mixing and melting of the material.
- Heating Elements: Maintain precise temperature control to ensure consistent material flow.
3. Screen Changer and Melt Pump:
- Screen Changer: Filters out impurities from the molten PET.
- Melt Pump: Ensures a consistent and controlled flow of the molten plastic to the die.
4. Sheet Mould:
- T-Die: Shapes the molten PET into a flat sheet with the desired width and thickness.
- Adjustable Lip: Allows fine-tuning of the sheet thickness.
5. 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.
6. 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.
7. Embossing Unit (optional):
- Embossing Rollers: Impart decorative patterns or textures onto the PET film.
8. Corona Treatment Unit:
- Corona Treater: Increases the surface energy of the film, enhancing its adhesion properties for printing or coating.
9. Edge Trimming and Slitting Unit:
- Edge Trimmers: Remove the edges of the sheet to ensure uniform width.
- Slitting Blades: Cut the sheet into desired widths if multiple smaller sheets are needed.
10. Haul-Off Unit:
- Pull Rollers: Draw the sheet through the extrusion line at a controlled speed, ensuring uniform thickness and preventing stretching.
11. Winding Unit:
- Roll Winder: Collects the finished film onto rolls for easy handling, storage, and transport.
- Tension Control: Ensures even and tight winding of the film.
12. Control System:
- PLC (Programmable Logic Controllers) and HMI (Human-Machine Interface): Monitor and control various parameters of the extrusion process, such as temperature, pressure, speed, and thickness, ensuring consistent product quality.
13. Quality Control and Inspection Station:
- Sensors and Imaging Systems: Inspect the film for uniformity, defects, and other quality parameters.
This production line is designed for high efficiency and precision, producing PET/GAG decorative films with excellent clarity, mechanical properties, and surface quality.
These films are widely used in applications requiring attractive, durable, and versatile decorative materials.
