Automatic Film Coater XN-VC-300

Name: Automatic Film Coater XN-VC-300

Equipment Type: Laboratory Automatic Film Coater with Doctor Blade and Four-Sided Coating Modes

Product Code: XN-VC-300

Product Introduction:

The Automatic Film Coater XN-VC-300 is designed for precision surface coating of sheet-type substrates in laboratory and pilot-scale research environments. The system supports multiple coating modes, including doctor blade coating and four-sided coating, making it suitable for a wide range of functional material studies such as electrode slurries, ceramic films, polymer coatings, and advanced battery materials. The XN-VC-300 provides stable coating speed control and high mechanical precision, enabling reproducible film thickness and uniformity. As a result, it is widely used in lithium-ion battery research, solid-state battery development, and functional thin-film preparation.

Main Features:

• Multiple coating modes — supports both doctor blade coating and four-sided coating in a single platform
• Continuously adjustable coating speed — 0–100 mm/s range accommodates different slurry rheologies
• Precision linear guide and drive system — smooth and stable substrate movement
• Micrometer-adjustable blade gap — 0.01–3.5 mm range for accurate wet film thickness control
• Vacuum aluminum coating plate — reliable substrate fixation during coating (415 × 200 × 30 mm)
• Compact and rigid mechanical structure — improves coating repeatability and long-term stability
• Simple operation and straightforward maintenance — suitable for routine laboratory use
• Optional vacuum chuck width 50–150 mm — configurable for different substrate sizes

Main Specifications:

Values measured by Xnergy. Typical values for reference; not guaranteed unless otherwise specified.

Application Areas:

• Lithium-ion battery research — electrode slurry coating for laboratory cell development (NCM, LFP, LCO, LMO, graphite, Si-C)
• Solid-state battery development — composite electrode and solid electrolyte film preparation
• Functional thin-film preparation — optical films, sensor films, electrochromic films
• Ceramic film coating — slurry-based ceramic film deposition
• Polymer coating studies — polymer film research
• Advanced battery material research where precision film thickness and uniformity are required

Recommended Operating Procedure:

1. Place the XN-VC-300 on a stable laboratory benchtop or workstation with adequate working space and good lighting; connect the power supply per local electrical standards (300 W). 2. Power on the XN-VC-300 and verify that the vacuum aluminum coating plate, linear guide, drive system, and blade-gap mechanism are operating normally. 3. Select the appropriate coating mode (doctor blade or four-sided coating) and corresponding tooling. 4. Place the substrate (foil or membrane) on the vacuum aluminum plate (415 × 200 × 30 mm) and engage the vacuum to fix the substrate firmly. 5. Set the target blade gap (within 0.01–3.5 mm) using the micrometer adjustment, according to the desired wet film thickness. 6. Set the target coating speed (within 0–100 mm/s). 7. Load the coating slurry, then initiate the coating run; the linear guide and drive system advance the coating along the 300 mm stroke. 8. After completion, release the vacuum and remove the coated sample for downstream drying. 9. After each run, clean all wetted surfaces with appropriate solvent (water or NMP, depending on the slurry system used) and dry thoroughly before the next run. 10. Inspect the linear guide, vacuum line, blade-gap mechanism, and drive system periodically for wear, contamination, or signs of degradation.

Maintenance:

• Frequently wipe the machine with a soft cloth dampened with alcohol to keep it clean
• Lubricate moving parts (especially the linear guide) with oil to keep movement smooth
• If the machine will not be used for an extended period, wipe down the surface of moving components and apply a protective rust-prevention oil
• Periodically inspect screws, nuts, pins, and other fasteners across all parts of the machine to prevent loosening
• Periodically inspect the vacuum line and chuck seals to ensure consistent substrate fixation
• Periodically inspect the blade edge and micrometer adjustment for wear or contamination affecting coating thickness

Packaging & Storage:

The XN-VC-300 ships fully assembled with the vacuum aluminum coating plate (415 × 200 × 30 mm), micrometer-adjustable blade-gap mechanism, vacuum chuck, precision linear guide, drive system, motor, and optional accessories (vacuum chuck widths 50–150 mm) as ordered. Store on a stable laboratory bench or workstation in a clean, dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. Disconnect the power supply when the equipment is not in active use. After each use, clean all wetted-surface components (vacuum plate, blade, chuck), dry thoroughly, and store in a clean, dry environment. Inspect the linear guide, drive system, vacuum line, and blade-gap mechanism periodically for wear or signs of degradation.

Safety:

For research and industrial laboratory use only. During operation, do not insert hands or any other body parts into the moving blade, linear guide, drive system, or any other moving or hazardous working areas to prevent personal injury. Operation by two or more persons simultaneously is not allowed to avoid accidental injury. External (third-party) technical personnel and unauthorized persons must not disassemble the equipment under any circumstances. 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. Keep loose clothing, hair, and jewelry away from the moving blade and drive components. Disconnect the power supply before any cleaning, maintenance, or component replacement. 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, coating thickness, substrate type, ambient operating conditions (temperature, humidity), and operator technique — consult published literature and our technical team for guidance on specific coating protocols.
