Jwell
Jwell TPU (Thermoplastic Polyurethane) casting composite film extrusion line is designed to produce high-quality TPU films, often combined with other materials to create composite structures. These films are widely used in various industries due to their excellent properties such as flexibility, abrasion resistance, and durability.
1. Raw Material Feeding System:
- Hopper and Feeder: TPU pellets are loaded into a hopper. A precise feeder ensures consistent material flow into the extrusion line.
2. Extruder:
- Screw and Barrel: The extruder melts the TPU pellets, pushing them through a screw and barrel system. The design of the screw is crucial for achieving a homogeneous melt.
- Temperature Control: Precise temperature settings are critical for processing TPU, which has a narrow processing window.
3. T-Die or Slot Die:
- The die shapes the melted TPU into a thin film. This component ensures uniform thickness and width of the extruded film.
4. Casting and Cooling System:
- Casting Roller: The extruded TPU film is cast onto a chilled roller, which cools and solidifies the film quickly. The casting roller often has a mirror finish to produce a smooth film surface.
- Cooling Rollers: Additional cooling rollers may be used to further solidify the film and control its final thickness and properties.
5. Composite Layer Application (if applicable):
- Laminate Station: For composite films, additional layers (such as fabric, non-woven materials, or other films) can be laminated onto the TPU film. This process typically involves adhesive application and a series of pressure rollers to bond the layers together.
6. Haul-Off Unit:
- This unit pulls the film through the line at a controlled speed, ensuring proper tension and alignment.
7. Corona Treatment:
- Corona treatment may be applied to the film surface to enhance its adhesion properties for subsequent printing or lamination processes.
8. Winding and Cutting:
- Winding Unit: The finished film is wound onto rolls for storage and transportation. Precision winding ensures consistent tension and alignment.
- Cutting Unit: If required, the film can be slit to specific widths or cut into sheets.
9. Control System:
- A centralized control system monitors and controls the entire process, ensuring consistent quality and synchronization between different components.
- Flexibility: TPU films are highly flexible, making them suitable for various applications requiring elasticity.
- Abrasion Resistance: TPU offers excellent resistance to wear and tear.
- Chemical Resistance: Resistant to many oils, solvents, and chemicals.
- Durability: TPU films are long-lasting and maintain their properties over a wide range of temperatures.
- Transparency: TPU can be made into clear films, which is beneficial for applications needing visibility.
- Textile and Apparel: Used in waterproof and breathable clothing, footwear, and accessories.
- Medical: Applied in medical devices, wound care products, and protective covers.
- Automotive: Utilized in interior components, protective films, and seals.
- Packaging: High-performance packaging solutions for food and industrial products.
- Consumer Goods: Applied in sports equipment, inflatable products, and various consumer items.
Jwell TPU casting composite film extrusion line is a specialized production system designed to create high-performance TPU films, often combined with other materials to form composites. The process involves precise control over various parameters to ensure the production of consistent, high-quality films suitable for a wide range of demanding applications.
| Model | Produts Width(mm) | Products Thickness(mm) | Max. Capacity(kg/h) |
| JWS120/36 | 1000-3000 | 0.02-2.0 | 200-300 |
| JWS120+JWS75 | 1000-3000 | 0.02-2.0 | 250-350 |
| JWS130/36 | 1000-3000 | 0.02-2.0 | 300-400 |
| JWS150/36 | 1000-3000 | 0.02-2.0 | 400-500 |
| The specifications are subject to change without prior notice. | |||
The production line adopts one-step casting and laminating mode. The production line has high-speed automation function, and realizes single-sided or double-sided online composite forming mode, replacing the traditional offline two-step and three-step composite forming mode, reducing product production process, greatly reducing production cost and improving production efficiency, and at the same time improving composite strength and product quality.
