MSK-AFA-HRP-150 Benchtop Roll-to-Roll Tape Casting System with Heated Drying Bed and Hot Rolling Press
The MSK-AFA-HRP-150 is engineered for precise and continuous coating of electrode slurries and thin films, particularly suited for lithium-ion battery electrodes, solid-state electrolytes, and ceramic films. This benchtop roll-to-roll system automates substrate feeding and collection, enabling seamless processing from tape casting through drying and calendaring to final reeling.
The system integrates a bottom heated drying bed capable of uniform heating up to 90°C within a 1000 mm drying chamber, facilitating solvent evaporation and film stabilization. A hot rolling press with chromium-plated steel rollers applies up to 2 tons of force at temperatures reaching 200°C, allowing densification and thickness control of coated films immediately after drying.
Key Features
- Roll-to-roll operation with automatic substrate feeding and receiving for continuous processing.
- Doctor blade tape casting on a flat marble platform with coating thickness precision of 0.01 mm.
- Bottom heated bed providing uniform drying up to 90°C inside a 1000 mm long drying chamber.
- Hot rolling press with chromium-plated steel rollers, hardness HRC > 52, max temperature 200°C, and pressing force up to 2 tons.
- Electrostatic dust removal via destabilizing bar and air curtain to maintain a particle-free coating environment.
- Adjustable coating speed from 2 to 100 mm/s and substrate width up to 188 mm with roll diameter up to 80 mm.
- Two digital temperature controllers with programmable segments for precise roller heating control.

Typical Applications
The MSK-AFA-HRP-150 is ideal for research and development of lithium-ion battery electrodes, solid-state electrolyte films, and ceramic coatings. It supports continuous coating and densification of slurry-based films with precise thickness control and uniform drying, facilitating advanced material studies and prototype fabrication.
Configuration & Operating Notes
The system includes a 150 mm doctor blade; blades up to 180 mm width are supported optionally. Optional accessories include a 100 mm slot die head with syringe pump for ultra-thin film coating and precision peristaltic slurry pumps for continuous slurry delivery. Air-plasma surface cleaning is available upon request to enhance substrate preparation.
Users should note the roller hardness limitation: materials with hardness above HRC 45 are not suitable for calendaring on this system. The actual pressing force depends on material properties and roller gap settings. Temperature controllers allow programmable heating profiles with up to 30 segments for precise thermal management.
