Utilizes slot die extrusion coating

Extremely high coating uniformity: By precisely controlling the die gap and feed pressure, the areal density fluctuation can be kept within ±1%, achieving the highest precision among all coating processes.

High coating speed suitable for mass production: The coating speed can reach 80-100 m/min, making it highly suitable for large-scale continuous production. Over 90% of lithium battery mass production lines currently adopt this process.

Closed system, anti-contamination: The slurry is transported inside the sealed die without exposure to air, effectively avoiding foreign contamination and slurry property changes to ensure slurry stability.

Good edge flatness: The die lip constrains the slurry, effectively suppressing the "thick edge effect" and achieving high consistency between the coating edge and center thickness.

High slurry utilization: As a pre-metered coating method, there is almost no excess slurry waste, and the material utilization is much higher than blade coating.

Supports multi-layer coating: Multi-layer die design allows simultaneous coating of multiple slurry layers in one pass, greatly improving production efficiency.

Flexible coating methods: Supports continuous full-width coating, intermittent stripe coating and zebra-pattern coating, among other pattern modes.

High-precision slot die coating: This bio-based cellulose hydrophobic transparent film coating & laminating machine adopts advanced slot die extrusion coating technology, with coating precision up to 0.005 mm, ensuring extremely uniform film thickness.

Efficient UV curing system: The machine is equipped with a dedicated UV curing unit that instantly cures the hydrophobic coating, greatly improving production efficiency while ensuring coating performance.

Multi-function integrated design: This machine integrates the entire flow of unwinding, coating, lamination, curing and peeling-winding, completing complex process verification on a single machine.

Top choice for medium-size sampling: Designed for research, this machine offers a 500 mm effective coating width and a Max 15 m/min speed, perfectly balancing experimental flexibility and data reliability.

Precision modular structure: This machine adopts high-precision modular assembly, weighing up to 6800 kg with a robust frame and minimal vibration, ensuring stable high-speed production.

Broad process adaptability: This machine supports 0-500 mm width adjustment, combined with precise pneumatic control (0.5-0.8 MPa), easily meeting the coating R&D needs of various bio-based materials.
