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. As a result, the system is ideal for research institutions, universities, and industrial R&D centers requiring high repeatability and process flexibility.

Product Features:

• Supports continuous three-roll transfer coating for stable and uniform film formation
• Adjustable coating speed and coating gap enable precise thickness control
• Integrated drying oven with adjustable temperature for efficient solvent evaporation
• Upper and lower hot-air circulation drying improves drying efficiency and coating quality
• High-precision tension control ensures smooth substrate transport and coating stability
• Modular structure allows easy parameter adjustment and process optimization
• PLC control with touchscreen HMI provides intuitive operation and reliable automation
• Optional solvent recovery system available for environmentally friendly operation

Main Specifications:

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

Application Areas:

• Battery electrode coating — continuous transfer coating for laboratory and pilot-scale lithium-ion battery cell development
• Supercapacitor electrode coating — uniform thin-film deposition for supercapacitor research
• Solid-state battery materials — controlled coating of solid-state battery components
• Advanced energy materials — functional material coating for next-generation energy storage research
• Process development, material screening, and pilot-scale validation
• Laboratory and industrial R&D centers requiring high repeatability and process flexibility

Recommended Operating Procedure:

1. Power on the XN-RTCA-300 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. 2. Connect the compressed air supply (0.5–0.7 MPa) to the equipment air inlet. 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.

Optional Solvent Recovery System:

The XN-RTCA-300 supports an optional solvent recovery and treatment module for environmentally friendly operation. The solvent recovery 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. Optional solvent recovery and treatment module ships separately if ordered. Install on a stable laboratory floor or workstation in a clean, dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. Connect the equipment to a compressed air supply (0.5–0.7 MPa) and to a power supply matching local electrical standards. Disconnect the power 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. Inspect the three-roll coating station, drying oven, tension control mechanism, rewind drive, and PLC system periodically for wear or contamination.

Safety:

For research and industrial laboratory use only. Always follow standard laboratory safety protocols when operating coating equipment with heated surfaces. Do not touch the heated drying oven, coated substrate, or hot-air ducts during operation — surface temperatures up to 120 °C can cause 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 environment, install the optional solvent recovery and treatment module if available, and follow local regulations on solvent use, recovery, and emission. 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. Keep hands clear of the moving three-roll coating station, tension rollers, and rewind drive during operation. 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.
