HDS-250 Hybrid Film Applicator with 250mm Doctor Blade and 150mm Slot Die Head
The HDS-250 is engineered to meet the demands of laboratory-scale film coating applications requiring both thick and thin film deposition. It supports tape coating for thicker films and slot die coating for ultra-thin films, making it ideal for producing battery electrodes, perovskite solar cell layers, and fuel cell membranes with precise control over film thickness.
This hybrid applicator integrates two stainless steel components: a 250 mm wide doctor blade and a 150 mm wide slot die head. The doctor blade is equipped with dual micrometers allowing film thickness adjustment from 0.01 mm up to 5 mm. The slot die head, which can be mounted onto the doctor blade, enables coating of films as thin as 0.005 mm to 0.02 mm. This versatility allows users to switch between coating methods depending on the material and film requirements.
Wichtigste Merkmale
- Dual-function design combining doctor blade and slot die coating heads.
- Doctor blade width: 250 mm with dual micrometers for precise thickness control from 0.01 mm to 5 mm.
- Slot die width: 150 mm with included shims (0.2 mm, 0.3 mm, 0.4 mm) for fine thickness adjustment between 0.005 mm and 0.02 mm.
- Digital micrometer heads with ±0.001 mm accuracy integrated into the doctor blade frame.
- PTFE buffering pad under the doctor blade to reduce friction during coating.
- Constructed entirely from stainless steel for durability and chemical resistance.
- Compatible with all brands of flat film coaters; slot die head is removable for tape coating use.

Typische Anwendungsbereiche
Ideal for coating battery electrode slurries, perovskite solar cell films, and fuel cell membrane layers in research and development settings. Suitable for use with various slurry materials requiring precise film thickness control.
Hinweise zur Konfiguration und zum Betrieb
The slot die head is removable to allow switching between tape coating and slot die coating modes. The applicator is compatible with all brands of flat coating machines. For optimal performance, pairing with a flat coater such as the MSK-AFA-II is recommended due to its glass surface flatness of ±2 microns. Optional syringe pumps can be used to supply slurry to the slot die for controlled flow during coating.
