Jwell
Jwell Thermoplastic Polyurethane (TPU) high and low temperature film production lines are designed to manufacture TPU films that exhibit different thermal properties, suitable for a variety of applications ranging from industrial to consumer products. Here is an introduction to such production lines:
1. Raw Material Handling and Feeding:
- Raw Material Storage: High-quality TPU pellets or granules are stored in silos or hoppers.
- Feeding System:An automatic feeding system conveys the raw materials into the extrusion system, ensuring a consistent and controlled supply.
2. Extrusion System:
- Extruder: The core component where TPU granules are melted and homogenized. It consists of a screw and barrel designed to handle the specific viscosity and thermal properties of TPU.
- Temperature Control: Precise temperature control systems are essential to maintain the optimal processing temperature for high and low temperature TPUs.
3. Die Head and T-Die:
- Die Head: Shapes the molten TPU into a flat film. The design of the die head can significantly affect the film quality.
- T-Die: Ensures the even distribution of the melt, forming a uniform film width and thickness.
4. Casting Unit:
- Casting Roller: Cools and solidifies the extruded film. Temperature control of the roller is crucial for achieving desired film properties.
5. Orientation Unit (if applicable):
- Machine Direction Orientation (MDO): Stretches the film in the machine direction, enhancing its mechanical properties.
6. Annealing and Cooling System:
- Annealing: Relieves internal stresses within the film and stabilizes its dimensions.
- Cooling: Additional cooling systems may be employed to bring the film to ambient temperature.
7. Winding and Slitting:
- Winding: The finished film is wound into rolls. The tension control system ensures even winding without wrinkles or distortions.
- Slitting (optional): Cuts the film into desired widths for different applications.
- Versatility: Capable of producing both high-temperature and low-temperature TPU films by adjusting process parameters.
- Precision Control: Advanced control systems for temperature, pressure, and film thickness to ensure consistent quality.
- Customization: Ability to produce films with various properties, such as different levels of hardness, elasticity, and transparency.
- Efficiency: Designed for 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 films produced on such lines are used in various industries, including:
- Automotive: Protective films, interior trims, and airbags.
- Textiles: Waterproof and breathable membranes, laminates, and performance fabrics.
- Medical: Protective coverings, inflatable products, and wound care.
- Electronics: Protective films, flexible circuits, and display technologies.
- Industrial: Conveyor belts, seals, and gaskets.
TPU film production lines are advanced systems that require precise control and high-quality components to produce films that meet the demanding specifications of various applications. The ability to produce both high and low temperature films enhances their versatility and application range.
| Model | Products Width(mm) | Products Thickness(mm) | Max. Capacity(kg/h) |
| JWS75/JWS120 | 1000-3000 | 0.02-2.0 | 300-350 |
| JWS90/JWS90/JWS90 | 1000-3000 | 0.02-2.0 | 200-300 |

TPU high and low temperature film is single-sided viscous, mainly used for the surface of the product, play a decorative waterproof and certain protective role. The melting point of TPU high and low temperature film is about 180℃-200℃.
TPU high and low temperature film, due to its soft, skin-friendly, high elasticity, three-dimensional sense, easy to use and othercharacteristics, is widely used in footwear, clothing, luggage, waterproof zipper and other textile fabrics, such as: sports footwear industry vamp, shoe tongue label, trademark and decorative accessories, luggage strap, reflective safety label, LOGO and so on.
Due to its excellent elasticity and bonding strength, TPU high elastic film is widely used in top-grade seamless underwear, seamless sportswear and other non-sutured fabrics.
The production line adopts two or three extruders with inner co-extrusion design technology die head. Due to a specially designed thermal insulation die head, each layer temperature can be free and independent controllled. In order to reach the one step co-extrusion of different materials or different process temperature materials, meet the production of diversified combination products of various materials and solve the limitation that normal co-extrusion technology can not make such kind film at the same time due to the large difference of material properties and temperature, the temperature of each layer can be controlled independently with this special design of thermal insulation die.
