High-Speed Industrial Curtain Coater with Customizable Coating Width (Up to 2200mm) and Non-Contact Coating Technology

This customizable curtain coater uses a free-falling liquid curtain to apply uniform coating layers onto flat or slightly profiled substrates in a non-contact, high-speed continuous process. Available in industrial high-speed, laboratory R&D, and multi-layer premium finish configurations.

Unlike roller or spray coating, curtain coating is a pre-metered, non-impact process that delivers excellent coverage at lower coat weights without scratching or film-splitting defects. It achieves speeds up to 60-100 m/min and coat thickness variations within ±0.5% of target value.

Working principle: Coating material is pumped to the curtain head and forms a continuous falling curtain between adjustable knives. The substrate passes beneath at controlled speed, transferring liquid film uniformly. With recovery system, excess coating is recirculated, achieving ≥95% material efficiency.
