WPC Flooring Production Line
Jwell WPC Flooring Production Line produces lightweight, durable wood-plastic composite flooring with a foamed core, precision calendering, embossing, UV coating and automated profiling.
JWELL TPU PPF Production Line is specially designed for manufacturing high-quality thermoplastic polyurethane (TPU) paint protection films for automotive applications.
The production line integrates a specialized TPU extrusion system, precision T-die, four-roll casting and lamination unit, automatic upper and lower PET release film unwinding, online thickness measurement and automatic winding. These integrated technologies support stable film formation, uniform thickness and consistent optical appearance.
The specially engineered extrusion screw and hardened die lip help maintain stable material processing and precise film forming. High-precision servo-driven rollers and constant-tension release film lamination further improve film flatness and production stability.
Beyond TPU base film extrusion, JWELL also provides optical film coating equipment for downstream functional coating processes. By combining high-quality TPU base films with suitable protective topcoats and adhesive layers, manufacturers can develop finished PPF products with application-specific properties such as scratch resistance, self-healing performance, gloss enhancement and water repellency.

🏭Fully Automated Production
Automatic metering, winding and integrated process control for continuous operation.
The automatic material feeding and metering system provides a continuous and stable supply of TPU raw materials to the extrusion unit. Precise material feeding helps maintain consistent processing conditions, reduce production fluctuations and support reliable operation of the TPU paint protection film extrusion line. Appropriate TPU drying and moisture control can be integrated according to material processing requirements.
The extrusion system features a specially engineered screw and barrel designed for processing aliphatic TPU materials. Its optimized screw structure ensures stable material conveying, uniform plasticization and consistent melt quality. This specialized TPU extrusion technology supports the production of transparent PPF base films with reliable mechanical properties and uniform film formation.
The precision T-die is designed to distribute molten TPU evenly across the working width. Its specially hardened die lip improves wear resistance and supports long-term forming accuracy. When integrated with online thickness measurement and automatic die adjustment, the system helps minimize thickness variation and improve material utilization during TPU PPF film production.
JWELL’s four-roll casting and lamination system combines controlled film forming with stable upper and lower release film lamination. High-precision independent servo drives provide accurate roller synchronization and consistent composite processing. The system helps improve TPU film flatness, surface quality and lamination stability while reducing wrinkles and air entrapment.
The upper and lower PET release film unwinding units feature constant-tension control, automatic splicing and film spreading functions. These systems maintain consistent web feeding and proper film alignment during continuous TPU film casting and lamination, supporting stable production and reducing interruptions during release film roll changes.
The online thickness measurement system continuously monitors TPU film thickness and provides real-time production data. Through coordinated feedback to the automatic T-die adjustment system, it helps improve cross-web thickness uniformity and maintain consistent film quality. This closed-loop control is especially important for high-transparency TPU PPF base film manufacturing.
The automatic winding system maintains controlled tension and stable roll formation for finished TPU base films laminated with protective release films. Integrated control coordinates key production processes, including extrusion, casting, thickness adjustment and winding. The system can support remote monitoring and technical assistance according to the selected control configuration.
JWELL TPU PPF Production Line supports different production capacities and film specifications to meet the requirements of
professional automotive paint protection
film manufacturers.
For specific PPF constructions, the production line can be configured with coextrusion, casting-composite or release-film lamination technology according to the required film structure.
The extrusion stage produces the TPU base film, while functional layers such as clearcoat, self-healing coating, adhesive and hydrophobic coating can be added through subsequent precision coating and converting processes.

*Typical reference values. Final equipment specifications depend on TPU grade, film thickness, working width, target output, film structure and customer requirements.
Jwell’s current published TPU film information provides reference configurations covering approximately 0.02–2.0 mm film thickness, 600–1,800 mm film width and 50–300 kg/h output. These values should be treated as configuration references rather than universal production guarantees.
The primary application is the production of TPU base film for automotive paint protection film.
Finished PPF can be converted into transparent protective patterns for different areas.
PPF can be produced in different surface finishes and product structures according to the target automotive market.
For premium automotive applications, PPF can be engineered around a combination.
The actual performance depends on the complete PPF material and coating system.
TPU PPF can be used to protect high-impact and high-exposure exterior vehicle surfaces that are more vulnerable to stone chips, road debris, scratches and environmental contamination.
This application category also works well for partial PPF kits, where only high-risk areas of a vehicle are covered instead of the entire body.
TPU base films combined with specially formulated self-healing topcoats help reduce the appearance of minor surface scratches and enhance long-term paint protection.
A TPU PPF extrusion line is a production system used to manufacture TPU film that serves as the base material for automotive paint protection film. The line typically includes TPU drying, extrusion, die forming, casting, cooling, thickness control, slitting and winding.

TPU PPF is primarily used to protect painted automotive surfaces from stone chips, scratches, road debris, insects, stains and environmental exposure. Typical protected areas include hoods, bumpers, fenders, mirrors, door edges and rocker panels.
A reference Jwell TPU film configuration covers approximately 0.02–2.0 mm. The actual PPF film thickness depends on the target product and TPU formulation.
Yes. TPU film can be produced with high optical clarity when the appropriate TPU grade, drying conditions, extrusion process, die and cooling configuration are selected.
The line can be configured for multilayer or composite TPU film structures depending on the required product construction and downstream process.
Both polyester-based and polyether-based TPU can be considered depending on the required mechanical, hydrolysis, weathering, chemical and low-temperature performance. Final material selection should be confirmed with the TPU supplier and validated through production trials.
Yes. The line can be configured according to film thickness, working width, output, TPU grade, film structure, surface requirements, slitting format and winding requirements.

JWELL TPU Casting & Laminating Film Extrusion Line integrates precision casting, online lamination and automatic winding to produce TPU composite films and laminated fabrics for footwear, textiles and outdoor applications.
TPU requires controlled drying, temperature management, extrusion and cooling. Jwell has published TPU film extrusion solutions covering dedicated drying systems, TPU-specific screws, precision T-dies and controlled three-roll cooling.
PPF manufacturers need more than extrusion output. Film thickness consistency, surface quality, optical appearance, winding quality and web stability all affect downstream coating and converting.
The production line is therefore configured around the final film specification rather than only the extruder capacity.
Different PPF products can require different combinations.
The equipment configuration can be adjusted according to these requirements.
