Thermoplastic Polyurethane (TPU) multi-groups casting composite film production lines are advanced systems designed to produce high-performance composite films. These films combine multiple layers of TPU and other materials to achieve specific properties such as enhanced strength, flexibility, and functionality. Here is an introduction to the components and features of Jwell TPU multi-groups casting composite film production line:
| Model | Products Width(mm) | Products Thickness(mm) | Max. Capacity(kg/h) |
| JWS120/JWS120 | 1000-3000 | 0.02-2.0 | 400-600 |
| JWS90/JWS90/JWS90 | 1000-3000 | 0.02-2.0 | 250-350 |
| JWS90/JWS120/JWS90 | 1000-3000 | 0.02-2.0 | 350-450 |
| The specifications are subject to change without prior notice. | |||
This production line adopts multiple extruders and multiple sets of unwinding devices, step by step flow casting forming, and realizes one-step composite forming, which can be equipped with on-line multi-group thickness measurement control. The production line designs various composite methods and one production line can realize various production processes of product forms. For some special fabrics, it can be connected with the fabric pretreatment and gluing production line synchronously to meet the production needs of customers for different products.
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.
- Versatility: Capable of producing multi-layer composite films with various combinations of materials and properties.
- Precision Control: Advanced control systems for temperature, pressure, and film thickness ensure consistent quality.
- Customization: Ability to produce films with different properties such as UV resistance, waterproofing, breathability, and high strength.
- Efficiency: High-speed production with minimal downtime for maintenance and material changeovers.
- Safety: Equipped with safety features to protect operators and maintain a safe working environment.
TPU multi-groups casting composite films produced on these lines are used in various sectors, including:
- Automotive: Protective films, interior trims, and seat covers.
- Textiles: Waterproof and breathable membranes, laminates for outdoor gear, and performance fabrics.
- Medical: Protective coverings, wound care products, and inflatable medical devices.
- Electronics: Protective films, flexible circuits, and display technologies.
- Industrial: Conveyor belts, seals, gaskets, and high-performance packaging.
TPU multi-groups casting composite film production lines are advanced systems designed to produce high-quality composite films tailored for various applications. These lines emphasize precision, efficiency, and versatility, meeting the specific needs of different industries to deliver films with enhanced performance and functionality.
