Slot-Die Extrusion Film Applicator XN-FAS-100

Name: Slot-Die Extrusion Film Applicator XN-FAS-100

Equipment Type: Laboratory Slot-Die Extrusion Film Applicator with Integrated Doctor-Blade Coating

Product Code: XN-FAS-100

Product Introduction:

The Slot-Die Extrusion Film Applicator XN-FAS-100 is primarily used for surface film coating of sheet substrates. It integrates slot-die extrusion coating and doctor-blade coating functions into a single device. The system is suitable for a wide range of coating research applications, including battery electrode coatings, OLED functional layers, photovoltaic materials, and other advanced thin-film processes. As a result, the XN-FAS-100 enables uniform and controllable film formation with high coating precision.

Main Features:

• Integrated design — supports both slot-die extrusion coating and doctor-blade coating processes in a single device
• Slot-die extrusion coating — provides excellent film uniformity and smooth surface quality
• Compact structure with small footprint — suitable for laboratory benchtop use (~L180 × W110 × H110 mm, ~2 kg)
• SUS630 stainless steel die and blade — high-quality corrosion-resistant material for long service life
• Precision mechanical adjustment — twin micrometer adjustment screws enable accurate and repeatable coating control
• 1 μm micrometer resolution — fine-grained thickness control for thin-film applications
• 2.6 mL die cavity — efficient slurry use for small-batch coating experiments
• Refined industrial design with simple operation and easy maintenance

Two Coating Modes in One Device:

Application Areas:

• Battery electrode coatings — slot-die extrusion or blade coating for laboratory cell development (lithium-ion cathode/anode, solid-state batteries, sodium-ion batteries)
• OLED functional layers — uniform thin-film deposition for organic electronics research
• Photovoltaic materials — functional layer preparation for solar cell research (perovskites, organic photovoltaics)
• Advanced thin-film processes — laboratory-scale deposition of functional thin films
• Coating research where uniform film formation and high coating precision are required
• Polymer film research, sensor films, and other specialty thin-film applications

About SUS630 Stainless Steel:

SUS630 is a precipitation-hardening martensitic stainless steel (also known as 17-4 PH) widely used in precision tooling and laboratory equipment that require both corrosion resistance and high mechanical strength. The XN-FAS-100 uses SUS630 for both the extrusion die and the blade, providing tight dimensional tolerance over long service life and compatibility with a wide range of coating formulations including NMP-based and aqueous slurries.

Recommended Operating Procedure (Slot-Die Extrusion Mode):

1. Clean the extrusion die cavity, slit opening, and feed inlet with appropriate solvent (water or NMP, depending on the slurry system used) before each use; dry thoroughly. 2. Use the twin micrometer adjustment screws to set the target slit gap; ensure both micrometers are set to the same height for uniform film thickness across the coating width (≤4 μm straightness deviation). 3. Place the substrate on a flat coating plate or on the vacuum coating plate of an automatic film coater. 4. Position the slot-die applicator on the substrate at the starting edge. 5. Load the coating slurry into the die cavity (cavity volume 2.6 mL); for larger volumes, use the inlet feed port for continuous supply from an extrusion feeding pump (such as the XN-EFP). 6. Draw the applicator across the substrate at a steady, controlled speed to extrude the slurry through the slit and form the wet film. 7. Allow the coated film to flow out and self-level if required by the slurry rheology, then transfer the substrate for downstream drying.

Recommended Operating Procedure (Doctor-Blade Mode):

1. Clean the blade and adjustment surfaces with appropriate solvent before each use; dry thoroughly. 2. Use the micrometer adjustment to set the target wet film thickness; the maximum adjustment height is 5.5 mm with 1 μm resolution. 3. Place the substrate on a flat coating plate or on the vacuum coating plate of an automatic film coater. 4. Position the applicator on the substrate at the starting edge. 5. Load the coating slurry in front of the blade. 6. Draw the applicator across the substrate at a steady, controlled speed to produce the wet film (≤4 μm blade flatness across the 150 mm coating width). 7. Transfer the substrate for downstream drying.

Maintenance:

• Frequently wipe the applicator with a soft cloth dampened with alcohol to keep it clean
• After each run, clean the die cavity, slit opening, and blade edge thoroughly with appropriate solvent and dry before storage to prevent slurry buildup that could affect future film thickness uniformity
• If the applicator will not be used for an extended period, wipe down the SUS630 surfaces and store in a clean, dry environment
• Periodically inspect the micrometer adjustment screws for smooth operation and accurate calibration
• Periodically inspect the blade edge and slit opening for nicks, wear, or contamination affecting film thickness uniformity; replace if compromised

Packaging & Storage:

The XN-FAS-100 ships fully assembled with the SUS630 stainless steel extrusion die, SUS630 blade, twin micrometer adjustment screws, slurry inlet port, and integrated mounting frame (~L180 × W110 × H110 mm, ~2 kg). Store on a clean laboratory bench or in a protective case in a dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. After each use, clean the die cavity, slit opening, and blade thoroughly with appropriate solvent and dry before storage. Inspect the micrometer adjustment screws and blade edge periodically for wear or contamination.

Safety:

For research and industrial laboratory use only. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling slurries, solvents, and coated substrates. When working with NMP-based slurries or other regulated solvents, operate in a well-ventilated fume hood and follow local regulations on solvent use and recovery — NMP and similar aprotic solvents have specific exposure limits under OSHA, EU REACH, and other regional safety frameworks. Handle the applicator carefully — the precision blade edge and slit opening can be damaged by impact or improper cleaning, affecting future film thickness uniformity. The SUS630 blade edge is sharp; avoid finger contact with the edge during handling and cleaning to prevent cuts. Refer to the included user manual for complete safety and operating instructions.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the specific slurry chemistry, substrate type, applicator drawing speed, and ambient operating conditions — consult published literature and our technical team for guidance on specific coating protocols. The XN-FAS-100 is a manual film applicator without an integrated drive system; for automated coating workflows, see the Automatic Film Coater XN-VC-300 (300 mm stroke) or Automatic Film Coater XN-VC-800 (800 mm stroke). For integrated slot-die coating with PLC control, heating platform, and dual vacuum chambers, see the Slot-Die Coating System XN-SDC. For continuous slurry supply during slot-die coating, pair the XN-FAS-100 with the Extrusion Feeding Pump XN-EFP (0.05–5 mm/s, 20/30/50 mL PP syringes).
