Automatic Film Coater – Doctor Blade & Four-Sided Coating XN-VC-300 , 0–100 mm/s, 300 mm Stroke | Xnergy

Name: XN-VC-300 Automatic Film Coater

Equipment Type: Laboratory & Pilot-Scale Automatic Film Coater (Doctor Blade and Four-Sided Coating Modes)

Product Code: XN-VC-300

Product Introduction:

The XN-VC-300 Automatic Film Coater 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.

Product Features:

• Coating speed is continuously adjustable over a wide range to accommodate different slurry rheologies
• Precision linear guide and drive system ensure smooth and stable substrate movement
• Micrometer-adjustable blade gap enables accurate control of wet film thickness
• Vacuum aluminum coating plate provides reliable substrate fixation during coating
• Compact and rigid mechanical structure improves coating repeatability and long-term stability
• Simple operation and straightforward maintenance make it suitable for routine laboratory use

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
• Solid-state battery development — composite electrode and solid electrolyte film preparation
• Functional thin-film preparation
• Ceramic film coating
• Polymer coating studies
• Advanced battery material research where precision film thickness and uniformity are required

Recommended Operating Procedure:

1. Power on the XN-VC-300 and verify that the vacuum aluminum coating plate, linear guide, and drive system are operating normally. 2. Select the appropriate coating mode (doctor blade or four-sided coating) and corresponding tooling. 3. Place the substrate (foil or membrane) on the vacuum aluminum plate and engage the vacuum to fix the substrate. 4. Set the target blade gap (within 0.01–3.5 mm) using the micrometer adjustment, according to the desired wet film thickness. 5. Set the target coating speed (within 0–100 mm/s). 6. Load the coating slurry, then initiate the coating run; the linear guide and drive system advance the coating along the 300 mm stroke. 7. After completion, release the vacuum and remove the coated sample for downstream drying. 8. 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.

Packaging & Storage:

The XN-VC-300 ships fully assembled with the vacuum aluminum coating plate, blade-gap adjustment mechanism, vacuum chuck, and optional accessories 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. Inspect the linear guide, vacuum line, and blade-gap mechanism periodically for wear or contamination.

Safety:

For research and industrial laboratory use only. Always follow standard laboratory safety protocols when operating coating equipment. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling slurries, solvents, and coated electrodes. 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. 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, and ambient operating conditions — consult published literature and our technical team for guidance on specific coating protocols. The XN-VC-300 is a coating-only platform without an integrated heating module; for integrated coating-and-drying workflows, see the XN-VCH-300 Automatic Film Coater with Integrated Drying System.
