MSK-AFA-L1000 350 mm Width Tape Casting Sheet Coater with 120°C Heated Vacuum Bed and Micrometer Adjustable Doctor Blade
The MSK-AFA-L1000 is engineered to meet the demands of producing uniform thick films on substrates up to 350 mm wide and 1100 mm long. It is particularly suited for coating electrode materials used in cylindrical lithium-ion battery cells, such as the 21700 format. This coater integrates a heatable vacuum platform to ensure substrate stability and controlled drying during the coating process.
The system employs a micrometer-adjustable doctor blade applicator combined with a unique driving mechanism that delivers smooth, consistent coatings across various material types. The vacuum chuck, made from aluminum alloy, provides a flat surface with ±10 micron flatness and can be heated up to 120°C with precise temperature control within ±1°C, facilitating efficient drying of coated films.
Key Features
- Heatable aluminum vacuum chuck (1000 mm × 350 mm) with effective vacuum area of 930 mm × 300 mm and flatness ±10 microns.
- Micrometer-adjustable doctor blade applicator with 350 mm coating width and thickness accuracy of ±0.01 mm.
- Adjustable traverse speed from 0 to 100 mm/sec with stroke length up to 1000 mm.
- Precision temperature controller maintaining vacuum bed temperature up to 120°C with ±1°C accuracy.
- Designed specifically for coating electrodes of cylindrical cells, including 21700 battery formats.
- Optional IR light heating cover available for enhanced drying performance.
- Requires external vacuum pump (not included), recommended CE-compliant 120 L/min oilless vacuum pump.

Typical Applications
This coater is ideal for producing thick film electrodes for lithium-ion batteries, particularly cylindrical cell formats such as 21700. It supports coating of cathode and anode materials with precise thickness control and uniformity. The heated vacuum bed facilitates drying and adhesion of slurry coatings, improving electrode quality.
Configuration & Operating Notes
The MSK-AFA-L1000 includes a built-in pushing bar for the micrometer-adjustable applicator. An optional IR light heating cover can be added to enhance drying efficiency. A vacuum pump is required but not included; a CE-compliant 120 L/min oilless vacuum pump is recommended. Operation under a fume hood is advised for safety and environmental control. Additional accessories such as slurry mixers, viscosity testers, and dry ovens may be used to optimize coating consistency and drying.
