Name: Laboratory Transfer Coating Machine XN-RTCA-300

Equipment Type: Three-Roll Continuous Transfer Coating System with Integrated Hot-Air Drying & Rewinding

Product Code: XN-RTCA-300

Product Introduction:

The Laboratory Transfer Coating Machine XN-RTCA-300 is a three-roll transfer coating system designed for precision coating of functional materials in laboratory and small-scale R&D environments. The XN-RTCA-300 is widely used for coating processes involving battery electrodes, supercapacitors, solid-state batteries, and other advanced energy materials. The system enables controlled transfer coating with excellent thickness uniformity and surface quality, making it especially suitable for process development, material screening, and pilot-scale validation. The XN-RTCA-300 supports continuous coating operation and integrates coating, drying, and rewinding functions into a compact platform, making it ideal for research institutions, universities, and industrial R&D centers requiring high repeatability and process flexibility.

Main Features:

• Three-roll continuous transfer coating — stable and uniform film formation
• Adjustable coating speed and coating gap — precise thickness control across different formulations
• Integrated drying oven with adjustable temperature — efficient solvent evaporation, ambient–120 °C range
• Upper and lower hot-air circulation drying — improves drying efficiency and coating quality
• High-precision tension control — smooth substrate transport and coating stability, max 60 N adjustable
• Modular structure — easy parameter adjustment and process optimization
• PLC control with touchscreen HMI — intuitive operation and reliable automation
• High coating accuracy — ±0.5 μm thickness, ±1 μm uniformity
• Optional solvent recovery and treatment module — for environmentally friendly operation with NMP or other regulated solvents

Recommended Operating Procedure:

1. Install the XN-RTCA-300 on a stable laboratory or pilot-scale production floor in a clean, dry environment; connect the equipment to a compressed air supply (0.5–0.7 MPa) and to a power supply matching local electrical standards (5 kW max). 2. Power on the unit and verify that the PLC + touchscreen HMI, three-roll coating station, hot-air drying oven, tension control system, and rewind drive are all operating normally. 3. Mount the substrate roll on the unwind side and thread the substrate through the three-roll coating station, the hot-air drying oven, and onto the rewind shaft (max. Φ250 mm). 4. Configure the tension control setpoint on the touchscreen HMI (within the max. 60 N adjustable range) for stable substrate transport. 5. Set the target coating gap on the touchscreen HMI to achieve the desired wet film thickness (typical range 40–300 μm) with thickness accuracy ±0.5 μm. 6. Set the target coating speed (within 200–900 mm/min). 7. Set the target drying temperature on the touchscreen HMI (within ambient–120 °C) and allow the upper and lower hot-air circulation system to stabilize. 8. Load the coating slurry, then initiate the run; the substrate advances continuously through the three-roll transfer coating station and the hot-air drying oven, with finished material rewound on the rewind shaft. 9. Monitor coating thickness, uniformity, and tension during the run; adjust parameters as needed via the touchscreen HMI. 10. After the run, allow the heating system to cool, then remove the rewound roll. Clean all wetted surfaces with appropriate solvent (water or NMP, depending on the slurry system used) and dry thoroughly before the next run.

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
• Periodically clean the drying oven nozzles and inspect the chamber for residue buildup that could affect drying uniformity
• Periodically inspect the three-roll coating station for wear or contamination affecting coating thickness
• Periodically inspect the tension control system, rewind drive, and air-expanding shaft

Optional Solvent Recovery System:

The XN-RTCA-300 supports an optional solvent recovery and treatment module for environmentally friendly operation. The module captures and processes evaporated solvent (such as NMP) from the drying oven exhaust, reducing solvent emissions and supporting compliance with local environmental regulations on VOC discharge. Contact our team for solvent recovery configuration options matched to your specific slurry chemistry and recovery throughput requirements.

Packaging & Storage:

The XN-RTCA-300 ships fully assembled with the three-roll transfer coating station, integrated upper and lower hot-air circulation drying oven, tension control system, rewind shaft (max. Φ250 mm), PLC + touchscreen HMI control panel, and modular frame (~L1800 × W1030 × H1340 mm, ~800 kg net). Optional solvent recovery and treatment module ships separately if ordered. Install on a stable laboratory or pilot-scale floor in a clean, dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. Disconnect the power supply and isolate the compressed air supply when the equipment is not in active use. After each use, clean all wetted-surface components, dry thoroughly, and store the equipment in a clean, dry environment.

Safety:

For research and industrial use only. During operation, do not insert hands or any other body parts into the three-roll coating station, rotating tension rollers, rewind drive, hot-air drying oven, 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 drying oven, coated substrate, or hot-air ducts during operation — surface temperatures up to 120 °C can cause severe burns. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat, safety shoes) when handling slurries, solvents, and coated electrodes. When working with NMP-based slurries or other regulated solvents, operate in a well-ventilated environment, install the optional solvent recovery and treatment module if available, and follow local regulations on solvent use, recovery, and emission — NMP and similar aprotic solvents have specific exposure limits under OSHA, EU REACH, and other regional safety frameworks. Disconnect the power supply and isolate the compressed air 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.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the specific slurry chemistry, viscosity, coating thickness, drying temperature setpoint, drying length, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific transfer coating-and-drying protocols.
