HDS250D200 Hybrid Film Applicator with 250mm Doctor Blade and 200mm Slot Die Head for Precise Tape and Slot Die Coating
The HDS250D200 hybrid film applicator is engineered to address the diverse coating needs in laboratory research, particularly for producing uniform films of battery electrodes, perovskite solar cells, and fuel cell membranes. This versatile device integrates two coating methods: tape coating using a doctor blade and slot die coating, enabling precise control over film thickness across a broad range.
The applicator’s design allows it to be compatible with all brands of film coating machines, making it a flexible addition to existing lab setups. Its hybrid structure consists of a 250 mm wide stainless steel doctor blade and a 200 mm wide slot die head that can be mounted or removed depending on the coating method required.
Wichtigste Merkmale
- Dual-function hybrid applicator combining tape coating and slot die coating in one unit.
- Doctor blade width of 250 mm with dual micrometers for film thickness adjustment from 0.01 mm to 5 mm.
- Slot die head width of 200 mm capable of coating films as thin as 0.005 mm up to 5 mm thickness.
- Includes sets of stainless steel shims (0.2 mm, 0.3 mm, 0.4 mm) for precise gap control in slot die coating.
- Digital micrometer heads integrated into the doctor blade frame with ±0.001 mm accuracy for fine gap adjustments.
- PTFE tube and join connectors provided for fluid delivery to the slot die head.
- PTFE buffering pad installed beneath the doctor blade to reduce friction during coating.

Typische Anwendungsbereiche
Ideal for laboratory-scale coating of battery electrode slurries, perovskite solar cell films, and fuel cell membrane layers where precise control of film thickness and uniformity is critical.
Supports both thicker tape coatings and ultra-thin slot die coatings, enabling versatile experimentation and process development.
Hinweise zur Konfiguration und zum Betrieb
The slot die head is removable, allowing the applicator to switch between tape coating and slot die coating modes easily.
Recommended to use with a flat coating machine such as the MSK-AFA-II coater, which provides a lapped glass surface with flatness within ±2 microns for optimal coating quality.
Optional accessories include syringe pumps for controlled fluid delivery to the slot die head.
