MSK-AFA-300 Roll to Roll Coating System with Up to 3 Optional Coating Heads, 250mm Max Width, and Integrated Drying Oven
The MSK-AFA-300 is engineered for continuous roll-to-roll coating processes, primarily targeting electrode sheet fabrication in materials research environments. It automates the coating of flexible substrates up to 250mm in width and lengths reaching 500 meters, enabling efficient production of uniform coatings for battery and related applications.
This system integrates multiple functions including reeling and unreeling shafts with precise tension and alignment control, a slurry feeding mechanism, a coating blade assembly, and a baking oven for drying the coated material. The design supports various coating methods through three optional heads, allowing customization based on material properties and desired coating thickness.
Key Features
- Supports coating widths up to 250mm and lengths up to 500 meters automatically.
- Three optional coating heads: reverse comma blade (transforming), micro-gravure, and slot die for thicknesses from 5μm to 300μm.
- Integrated baking oven with maximum drying temperature of 150°C and ±1°C temperature accuracy.
- Precise tension control adjustable between 20 to 80N and alignment control within ±0.5mm using optical sensors.
- Touch screen control panel for managing slurry feed rate, coating speed (up to 750 mm/min), and oven temperature.
- Slurry stirring with SS316 moving rod to maintain homogeneity during coating.
- Optional upgrades include dual heating chambers, bilayer slot die heads, plasma surface treatment, and filtration systems for vapor control.

Typical Applications
The MSK-AFA-300 is suited for coating battery electrode sheets, thin films, and other functional layers requiring precise thickness control and uniformity. It is widely used in research and development labs focused on energy storage materials and flexible electronics.
Configuration & Operating Notes
Optional upgrades include dual heating chambers for enhanced drying control, bilayer slot die heads for multilayer coatings, and plasma surface treatment modules to improve substrate adhesion. The system requires an external air compressor or regulated gas supply for safe operation. Slurry viscosity recommendations vary by coating method, typically 2000–6000 cps for blade methods and 50–2000 cps for micro-gravure.
Safety certifications such as CE are standard; UL or CSA certification can be provided at additional cost. Proper installation of pressure regulators is critical when using gas cylinders instead of compressors.
