The entire line consists of core components such as raw material dehumidification and drying, extruder, screen changer, metering pump, filter, automatic mold, composite molding machine, upper and lower PET unwinding devices, thickness gauge, cooling and trimming, traction machine, storage rack, and dual-station automatic winding machine. The main process flow includes:
Raw material drying
TPU extrusion plasticizing
die casting
cooling and shaping
lamination of upper and lower release films
online thickness detection
automatic winding of finished product
The entire production line has a compact layout and a modular design that facilitates maintenance and upgrades.
TPU car paint protection film line Core Technology Characteristics
1. Dedicated screw design ensures excellent plasticizing effect and high output.
2. The double-sided PET release film uses constant tension control, automatic sheet splicing, and automatic flattening.
3. Utilizes a four-roll lamination machine, ensuring wrinkle-free and bubble-free lamination of PET and TPU film with excellent flatness.
4. High degree of automation: including an automatic material conveying and metering system, automatic PE sheet splicing, automatic mold making, automatic thickness measurement feedback, automatic winding, etc.
5. The electrical automation control system uses digital communication and fully integrated control, resulting in higher operating precision and more sensitive response speed for the entire equipment.
1. Casting composite molding machine
1. Unique four-roll casting design: The laminating machine has up/down and forward/backward movement capabilities, bringing the mold closer to the roller surface for easier operation and better lamination;
2. Each roller is independently driven, employing high-precision servo control and featuring a quick roller change device;
3. The rollers adopt a thin-walled structure, with multiple spiral water inlet channels and multiple spiral water outlet channels arranged alternately. Features include: rapid cooling and small temperature difference on the roller surface (less than 1°C).
2. Top and Bottom PET Lamination Unwinding
The top and bottom double-sided PET release film uses constant tension control + flattening rollers, resulting in excellent lamination flatness.
2. The unique design of the four-roll lamination machine ensures that the PET film is smoothly bonded to the TPU after entering the rollers: no wrinkles, no bubbles.
3. Automatic Sheet Splicing: The PET film can be automatically spliced before changing rolls, ensuring product quality and improving production efficiency.
4. Automatic Deviation Correction Function
During continuous production, it effectively reduces problems such as flow marks, bubbles, and unstable edges.
3. Material Storage + Fully Automatic Rewinding Machine
1. Constant tension control during rewinding, no stretching, smooth rewinding
2. Intermittent rewinding, no wrinkles, no air bubbles
3. Fully automatic rewinding process with automatic cutting, automatic loading, and automatic roll changing
4. Electrical control: Microcomputer integrated control, high-precision synchronization between rewinding speed and laminating machine speed, stable rewinding
5. Remote intelligent control available
4. Online Thickness Detection and Automatic Adjustment System
The equipment supports an online thickness monitoring device for real-time scanning and detection of the film.
The system achieves the following through data feedback:
* Automatic lateral thickness compensation
* Fine-tuning of extrusion amount
* Production fluctuation early warning
This is particularly important for PPF products with thickness control within the range of 0.1–0.2 mm, helping to improve finished product consistency and yield.
5. Automatic Tension Control and Lamination System
Invisible car wrap film typically needs to be laminated synchronously with upper and lower release films. Tension control accuracy directly affects the flatness of the finished product.
The entire line is equipped with an automatic tension control system, covering:
* Independent control of upper and lower release film unwinding tension
* Synchronized traction in the forming section

Frequently Asked Questions (FAQ)
1. What is TPU PPF(paint protection film) and what are its functions?
- Paint Protection Film (PPF) is a high-performance transparent functional film used for protecting automotive paint. These products typically use aliphatic TPU as the core material and are formed through a casting and lamination process, exhibiting good flexibility, weather resistance, and anti-yellowing properties.
- In practical use, TPU paint protection film effectively isolates the paint from the corrosive effects of air, moisture, and external pollutants, while maintaining the original gloss of the paint surface. Some high-end products also have heat-repair properties, which can repair minor scratches under certain temperature conditions.
2. What types of TPU materials is this TPU invisible car clothing production line suitable for?
- TPU car paint protection film is mainly designed for structural optimization of aliphatic TPU materials, making it suitable for the production of invisible car clothing films with high transparency and yellowing resistance requirements.
- When processing aliphatic TPU, the equipment uses a dedicated screw design and a zoned temperature control system to control melt stability, thereby reducing the risk of material degradation and improving film quality.
- If the customer uses other modified TPU materials, the process parameters can be adjusted according to the formulation.
3. Is this equipment suitable for startups or large manufacturers?
- Applicable to:
- New brand trial production stage
- OEM processing and production
- Medium and large-scale manufacturing
- Enterprises can choose the corresponding production capacity configuration according to their development stage.
4. Does the equipment installation and commissioning support provide support?
- Installation guidance and commissioning support services can be provided according to project requirements.
