MSK-AFA-W500H Large Automatic Film Coater with 500 mm Wide Marble Bed and Adjustable Film Thickness up to 5 mm
The MSK-AFA-W500H is engineered for laboratory and research applications requiring uniform thin film coatings on substrates up to 500 mm in width and 1000 mm in length. It is particularly suited for tape casting processes where precise control of film thickness and coating uniformity is critical. The system’s large marble platform provides a stable, flat surface with surface flatness maintained within ±2 microns, ensuring consistent coating quality.
This automatic coater incorporates a unique driving mechanism that facilitates smooth and even slurry application across various material types. Film thickness can be finely adjusted up to 5 mm using a pair of included digital micrometers. The coating length is continuously adjustable from 10 to 999 mm with a recommended maximum of 920 mm to maintain accuracy. Traverse speeds range from 500 to 5000 mm per minute, while coating speeds vary between 2 and 30 mm per second, both with tight tolerances for precision.
Key Features
- Precision marble platform (550 mm width x 1100 mm length) with flatness < ±2 microns.
- Digital micrometers for film thickness adjustment up to 5 mm.
- Doctor-blade film applicator with four precision rolling wheels for smooth coating.
- Coating length adjustable from 10 to 999 mm with ±1 mm deviation.
- Traverse speed adjustable from 500 to 5000 mm/min with 10 mm/sec accuracy.
- Coating speed adjustable from 2 to 30 mm/s with ≤1 mm/s deviation.
- Magnetic clamps and substrate fixture for secure sample positioning.

Configuration & Operating Notes
The system includes one tray for residual slurry collection and is mounted on a mobile cart with adjustable wheel height for positioning flexibility. Magnetic clamps on two sides and a tightened fixture on the right side secure substrates during coating. An optional slot-die coating head (500 mm width) and a heating cover capable of up to 100°C drying temperature are available as upgrades. CE certification is standard; NRTL or CSA certification can be provided upon request at additional cost.
