Automatic Film Coating & Drying Machine Plus XN-VCH-800

Name: Automatic Film Coating & Drying Machine Plus XN-VCH-800

Equipment Type: Large-Stroke Flow-Cast Film Coating Machine with Hot-Air Circulation Drying & Oil-Free Vacuum Pump

Product Code: XN-VCH-800

Product Introduction:

The Automatic Film Coating & Drying Machine Plus XN-VCH-800 is an 800 mm long flow-cast coating machine that integrates vacuum substrate fixation, hot-air circulation drying, and an oil-free vacuum pump in a single platform. The system is equipped with a unique automatic substrate-pushing mechanism that enables the production of smooth, uniform coatings up to 150 mm wide × 800 mm long on a wide range of substrate materials. The XN-VCH-800 is paired with an adjustable doctor blade for thick-film fabrication, making it suitable for laboratory and pilot-scale coating research applications requiring controlled in-line drying conditions.

Main Features:

• Hot-air circulation drying with digital temperature control — maximum operating temperature 130 °C
• Digital timer display — drying time freely configurable
• Adjustable coating speed over 0–120 mm/s range
• Vacuum aluminum substrate plate — supports rapid substrate placement and removal
• Adjustable coating stroke over 0–800 mm range — large stroke for long electrode sheets and large substrates
• Adjustable doctor blade — 0–5 mm blade gap for coating thickness control
• Automatic substrate-pushing system — enables smooth, uniform long-format coating
• Included oil-free vacuum pump — no oil contamination of substrates, no external vacuum source required
• Compact footprint — space-efficient design for laboratory benchtop or pilot-scale workstation installation
• Refined industrial design — sheet metal with three-dimensional geometric styling

Main Specifications:

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

Application Areas:

• Laboratory and pilot-scale flow-cast film coating research — single-pass coating-and-drying for thick-film fabrication
• Long-format thin-film fabrication — up to 150 mm × 800 mm coating area in a single pass
• Battery electrode coating with in-line drying — lithium-ion battery cathode/anode coating with integrated hot-air circulation drying for laboratory cell development
• Functional thin-film research — applications where in-line drying control is required, including optical films, sensor films, and electrochromic films
• Coating-and-drying process development at laboratory and pilot scale, including transition from benchtop coating-only platforms to inline coating-and-drying production
• Ceramic, crystalline, and specialty nano-film research with controlled in-line drying conditions

Recommended Operating Procedure:

1. Place the XN-VCH-800 on a stable laboratory benchtop or workstation with adequate working space and good lighting; connect the power supply per local electrical standards (2 kW). 2. Power on the XN-VCH-800 and verify that the vacuum aluminum plate, oil-free vacuum pump, hot-air circulation drying system, digital temperature controller, digital timer, doctor-blade adjustment, and automatic substrate-pushing system are all operating normally. 3. Place the substrate (foil or sheet-type material) on the vacuum aluminum plate (L900 × W200 × H32 mm) and engage the vacuum to fix the substrate firmly. 4. Set the target blade gap (within 0–5 mm) using the doctor-blade adjustment, according to the desired wet film thickness. 5. Set the target coating speed (within 0–120 mm/s) and coating stroke (within 0–800 mm). 6. Set the target drying temperature on the digital temperature controller (within ambient–130 °C). 7. Set the target drying time on the digital timer. 8. Load the coating slurry, then initiate the coating run; the automatic substrate-pushing system advances the coating along the configured stroke, and the hot-air circulation drying system performs in-line drying for the configured time. 9. After the configured drying time elapses, allow the substrate and platform to cool before removing the sample. 10. 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. 11. Inspect the doctor blade, vacuum plate, oil-free vacuum pump, heating system, and substrate-pushing 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 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, avoiding equipment-quality issues and personal-safety incidents
• Periodically inspect the oil-free vacuum pump’s seals and gaskets to ensure consistent vacuum performance
• Periodically inspect the doctor blade, hot-air circulation drying system, and automatic substrate-pushing mechanism for wear or contamination affecting coating quality or drying performance

Packaging & Storage:

The XN-VCH-800 ships fully assembled with the vacuum aluminum plate (L900 × W200 × H32 mm), oil-free vacuum pump, hot-air circulation drying system with digital temperature controller (ambient–130 °C), digital timer, doctor-blade adjustment mechanism with 0–5 mm gap range, automatic substrate-pushing system, and integrated control panel. 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, allow the heating system to cool to room temperature, then clean all wetted-surface components (vacuum plate, doctor blade, drying chamber), dry thoroughly, and store in a clean, dry environment. Inspect the oil-free vacuum pump, heating system, doctor-blade mechanism, substrate-pushing system, and digital controllers 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 doctor blade, automatic substrate-pushing 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 follow standard laboratory safety protocols when operating coating equipment with heated surfaces. Do not touch the heated platform, drying chamber, or coated substrate during operation — surface temperatures up to 130 °C can cause severe burns. 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 — NMP and similar aprotic solvents have specific exposure limits under OSHA, EU REACH, and other regional safety frameworks. Disconnect the power supply before any cleaning, maintenance, or component replacement. Allow the heating system to cool to room temperature before any cleaning or sample-handling operations. Refer to the included user manual for complete safety and operating instructions.

Actual performance depends on the specific slurry chemistry, coating thickness, drying temperature setpoint, drying time, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific coating-and-drying protocols.
