Complete high speed, wide width coating and lamination production capacity 20 Million running meters per year + for SOLAR & BATTERY Industry Applications

(DPR) presents a comprehensive, brand‑neutral, and model‑neutral assessment for setting up a high‑speed, wide‑width coating and lamination production line. The facility is designed for lamination of PET with PVF/PVDF substrates, primarily suitable for advanced technical films such as solar industry applications, lithium‑battery related films, electrical insulation films, and other functional laminated films.

The DPR is structured to meet the requirements of banks, financial institutions, investors, EPC contractors, and government authorities, and is suitable for subsidies, project finance, or internal approvals.

D. Manufacturing Process Description

D.1 Process Flow

1. Primary substrate unwinding
2. Optional corona treatment
3. Optional dust removal
4. Infeed and closed‑loop tension control
5. Precision micro‑gravure coating
6. Multi‑zone hot air drying oven
7. Web guiding and stabilization
8. Thermal lamination with secondary substrate
9. Cooling and dimensional stabilization
10. Web accumulation
11. Final rewinding

D.2 Working Principle

The primary substrate is coated using precision gravure technology. The coated web passes through a multi‑zone drying system to remove solvents and cure the coating. A secondary substrate is laminated under controlled heat and pressure. The laminate is cooled, accumulated, and rewound into finished rolls.
