1. Raw Material Handling and Feeding:
- Raw Material Storage: High-quality TPU pellets or granules, along with other composite materials, are stored in silos or hoppers.
- Feeding System: Automated feeding systems deliver the raw materials consistently into the extrusion system, ensuring precise control over the mixture of materials.
2. Extrusion Systems (Multiple):
- Extruders: Multiple extruders are used to melt and homogenize the TPU and other materials. Each extruder is designed to handle specific types of materials and layer compositions.
- Temperature Control: Precise temperature control for each extruder is essential to maintain optimal processing conditions for different materials.
3. Co-extrusion Die Head:
- Co-extrusion Die: Combines the melts from multiple extruders into a composite film structure. The die design ensures uniform distribution of each layer, resulting in consistent film properties.
- T-Die: Shapes the composite film into the desired width and thickness with high precision.
4. Casting Unit:
- Casting Rollers: Cool and solidify the composite film. The rollers are temperature-controlled to ensure even cooling and smooth surface finish.
- Release Paper or Film: Supports the composite film as it cools and solidifies, preventing sticking and ensuring a smooth finish.
5. Lamination Unit:
- Lamination Rollers: Laminate additional layers or reinforcement materials onto the composite film. This unit can add strength, barrier properties, or other functionalities to the final product.
- Adhesive Application (if needed): Applies adhesive layers to bond different materials securely.
6. Orientation Unit (if applicable):
- Machine Direction Orientation (MDO): Stretches the composite film in the machine direction to enhance mechanical properties.
7. Annealing and Cooling System:
- Annealing: Relieves internal stresses within the composite film, stabilizing its dimensions.
- Cooling: Additional cooling systems may be used to bring the film to ambient temperature.
8. Edge Trimming and Slitting:
- Edge Trimmers: Cut off the edges of the composite film to ensure uniform width.
- Slitting Unit: Cuts the composite film into desired widths according to specific application requirements.
9. Surface Treatment:
- Corona Treatment: Improves the surface energy of the composite film, enhancing printability and adhesion properties.
- Embossing (Optional): Adds textures or patterns to the film for decorative or functional purposes.
10. Winding and Stacking:
- Winding Unit: Rolls the finished composite film into coils for easy handling and transportation.
- Stacking System: Alternatively, the films can be cut to length and stacked.
