The Multi-Functional Coater is a continuous roll-to-roll coating and laminating system designed for laboratory R&D and small-scale pilot production on flexible web materials such as paper and film. It features an effective coating width of 280 mm, a roller face width of 300 mm, and an adjustable mechanical speed range of 0.5-5 m/min. The coating unit supports modular switching among metering rod, blade, gravure roll, and film-transfer methods. Unwind and rewind diameters are up to φ350 mm with 3" air shafts and automatic tension control, achieving edge alignment within ±2.0 mm. The drying system consists of two external stainless-steel electric-heated ovens with centrifugal fan hot-air circulation and precise temperature control from 30 to 120°C ±2°C. The entire line is centrally managed via a touchscreen HMI, with servo motors driving the coating and winding sections in active synchronization. Total installed power is approximately 6 kW. It is ideal for continuous coating process development and sample preparation of water-based and solvent-based coatings, battery slurries, optical films, and adhesives.
