MSK-AFA-MC300 Roll-to-Roll Multi-Functional Coating Machine with Multiple Coating Heads and Up to 300mm Substrate Width
The MSK-AFA-MC300 is engineered to address the challenges of applying uniform coatings on flexible substrates in a continuous roll-to-roll process. It accommodates substrates up to 300mm wide and offers an effective coating width from 50mm to 260mm, making it suitable for research and development or small-scale production of coated films. This system supports a variety of coating heads, enabling users to select or combine different coating techniques tailored to their slurry and substrate requirements.
The machine operates with both continuous and intermittent coating modes depending on the installed head. It integrates a convection heating oven with dual-direction hot air for controlled drying, and ultrasonic edge position control mechanisms ensure precise substrate alignment during winding and unwinding. Independent tension control on reeling shafts allows for stable substrate handling across various materials.
Key Features
- Supports seven coating head configurations: slot die, reverse comma blade, doctor blade, micro-gravure, and their combinations.
- Coating thickness ranges vary by head: slot die and reverse comma blade from 30 to 150 µm; micro-gravure from 1 to 10 µm dried film thickness.
- Coating gap controlled by servo motor with 1 µm resolution for precise thickness adjustment.
- Convection heating oven with max temperature 150°C and ±5°C uniformity for effective drying.
- Ultrasonic edge position control for automatic substrate alignment with ±0.5mm accuracy.
- Independent tension control on reeling and unreeling shafts adjustable from 0 to 60N.
- Compatible with a wide range of slurry viscosities and substrate materials.

Typical Applications
Ideal for coating thin films in battery electrode fabrication, flexible electronics, solar cells, and other advanced materials research requiring precise control over coating thickness and uniformity.
Configuration & Operating Notes
The system can be customized with multiple convection heating ovens to meet specific drying needs. The micro-gravure coating head mounts independently and can be combined with other heads upon consultation. Compressed air supply must be regulated within the specified pressure range for safe operation. The final coating thickness depends on multiple factors including slurry properties and process parameters; users are encouraged to provide slurry specifications for optimal setup advice.
