HDS300D Hybrid Film Applicator with 300mm Doctor Blade and 200mm Slot Die Heads for Precise Tape and Thin Film Coating
The HDS300D is engineered to meet the demanding needs of laboratory-scale film coating applications, particularly for battery electrode fabrication, perovskite solar cell films, and fuel cell membrane production. This hybrid applicator integrates two coating methods—tape coating for thicker films and slot die coating for ultra-thin films—into a single versatile device, enabling flexible experimentation and process development.
Constructed primarily from stainless steel for durability and chemical resistance, the HDS300D features a 300 mm wide doctor blade with dual micrometers allowing precise film thickness adjustment between 0.01 mm and 5 mm. The slot die head, measuring 200 mm in width, attaches securely to the doctor blade frame and supports coating thicknesses from 0.005 mm to 0.02 mm. This design facilitates seamless switching between coating modes depending on the film thickness requirements.
Key Features
- Hybrid design combining doctor blade tape coating and slot die thin film coating.
- 300 mm doctor blade width with dual micrometers for thickness control from 0.01 mm to 5 mm.
- 200 mm slot die head with six included shims (two each of 0.2 mm, 0.3 mm, and 0.4 mm) for fine thickness adjustment between 0.005 mm and 0.02 mm.
- Digital micrometer heads integrated into the doctor blade frame with ±0.001 mm accuracy for precise gap setting.
- PTFE buffering pad under the doctor blade to reduce friction during coating.
- Stainless steel construction for chemical resistance and durability.
- Slot die head is removable to allow exclusive use of the doctor blade for tape coating.

Typical Applications
The HDS300D is ideal for laboratory research and development involving slurry-based film coating processes. It is widely used for fabricating battery electrodes, coating perovskite solar cell layers, and producing thin membranes for fuel cells. Its hybrid capability allows users to switch between thicker tape coatings and ultra-thin slot die coatings without changing equipment.
Configuration & Operating Notes
The slot die head is removable, enabling exclusive use of the doctor blade for tape coating applications. For slot die coating, a compatible syringe pump can be ordered separately to supply slurry to the slot die. The digital micrometer heads integrated into the doctor blade frame allow precise adjustment of the gap between the slot die and substrate, ensuring consistent film thickness. The PTFE buffering pad reduces friction during coating operations, enhancing smooth film deposition.
