Bottom-Heated Film Coating Machine XN-VCHB

Name: Bottom-Heated Film Coating Machine XN-VCHB

Equipment Type: PLC-Controlled Film Coating Machine with Bottom Heating Plate & Integrated Vacuum Chuck

Product Code: XN-VCHB

Product Introduction:

The Bottom-Heated Film Coating Machine XN-VCHB is designed for high-temperature coating research applications, including ceramic coatings, crystalline coatings, battery electrode coatings, and specialty functional films. The system provides uniform bottom heating up to 150 °C and precise coating control, making it suitable for laboratory studies and process development requiring controlled thermal conditions during coating. Unlike Xnergy’s VCH coating-and-drying machines (where hot-air circulation drying takes place after the coating pass), the XN-VCHB heats the substrate from below during the coating pass itself, enabling temperature-controlled film formation as the slurry is being applied.

Main Features:

• PLC-based control system with touch screen — intuitive parameter setting and operation
• Bottom heating plate — uniform temperature distribution across the coating area, ambient–150 °C with ±2 °C accuracy
• High-precision coating thickness control — minimum resolution of 0.01 mm
• Adjustable coating speed — 0–120 mm/s, meets different material and process requirements
• Adjustable coating stroke — 0–300 mm
• Integrated vacuum adsorption platform — L415 × W200 × H32 mm, stable substrate fixation during coating
• Integrated vacuum unit — no external vacuum source required
• Compact structure — clean and modern industrial design
• Suitable for R&D of advanced functional films

Main Specifications:

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

Application Areas:

• Ceramic coatings — high-temperature ceramic film deposition under controlled bottom heating
• Crystalline coatings — temperature-controlled crystalline thin-film preparation
• Battery electrode coatings — electrode slurry coating with in-process bottom heating for solvent evaporation control
• Specialty functional films — optical films, sensor films, electrochromic films, and other functional thin films requiring temperature control during coating
• Polymer film research — temperature-sensitive polymer coatings where ambient coating produces poor film quality
• Laboratory studies and process development requiring controlled thermal conditions during the coating pass

Recommended Operating Procedure:

1. Place the XN-VCHB on a stable laboratory benchtop or workstation with adequate working space and good lighting; connect the power supply per local electrical standards (1 kW). 2. Power on the XN-VCHB and verify that the bottom heating plate, integrated vacuum unit, PLC, touch screen, blade-gap mechanism, and motor drive are operating normally. 3. Place the substrate (foil or sheet-type material) on the integrated vacuum adsorption platform (L415 × W200 × H32 mm) and engage the vacuum chuck to fix the substrate. 4. Set the target heating temperature on the PLC touch screen (within ambient–150 °C range, ±2 °C accuracy). Allow the bottom heating plate to reach the setpoint and stabilize before starting the coating run. 5. Set the target blade gap (within 0–5 mm) using the blade-gap adjustment, with 0.01 mm thickness control resolution. 6. Set the target coating speed (within 0–120 mm/s) and coating stroke (within 0–300 mm). 7. Load the coating slurry. 8. Initiate the coating run; the system advances the coating across the heated platform under bottom-heating conditions, enabling temperature-controlled film formation. 9. After completion, allow the substrate and heating plate 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 heating plate, vacuum chuck, blade-gap mechanism, and PLC 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 integrated vacuum unit’s seals and gaskets to ensure consistent vacuum performance
• Periodically inspect the bottom heating plate and its temperature sensor for accurate temperature control

Packaging & Storage:

The XN-VCHB ships fully assembled with the integrated vacuum adsorption platform (L415 × W200 × H32 mm), bottom heating plate with digital temperature controller (ambient–150 °C, ±2 °C), blade-gap adjustment mechanism with 0.01 mm resolution, integrated vacuum unit, PLC control system with touch screen, and motor drive. 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 plate to cool to room temperature, then clean all wetted-surface components (vacuum chuck, doctor blade, heating plate surface), dry thoroughly, and store in a clean, dry environment. Inspect the heating plate, vacuum unit, blade-gap mechanism, and PLC system 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, motor drive, 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. Do not touch the heated bottom plate, vacuum chuck surface, or coated substrate during operation — surface temperatures up to 150 °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. Be aware that bottom heating during coating accelerates solvent evaporation, increasing VOC release rates compared to ambient-temperature coating; ensure ventilation capacity matches the elevated solvent emission rate. Disconnect the power supply before any cleaning, maintenance, or component replacement. Allow the heating plate to cool to room temperature before any cleaning or sample-handling operations. 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, heating temperature setpoint, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific bottom-heated coating protocols.
