Name: Segmented Transfer Coating Machine XN-RTCA-300-3

Equipment Type: Pilot-Scale Continuous Slot-Die Transfer Coating Machine with Multiple Independent Drying Zones

Product Code: XN-RTCA-300-3

Product Introduction:

The Segmented Transfer Coating Machine XN-RTCA-300-3 is a pilot-scale continuous coating system designed for precision surface coating of various functional materials. The XN-RTCA-300-3 is especially suitable for lithium-ion battery electrode fabrication, enabling uniform slurry coating and controlled drying in a segmented, modular configuration. The system integrates coating, drying, and material transport into a single continuous process, offering high coating efficiency and excellent film quality. As a result, the XN-RTCA-300-3 is widely used in battery R&D, process development, and small-batch pilot production environments.

Product Features:

• Segmented modular drying zones allow independent temperature control for each section, enabling optimized drying profiles

• Supports a wide range of coating materials and substrate types, suitable for different battery electrode formulations
• High coating precision with excellent thickness uniformity and surface consistency
• Hot-air circulation drying system ensures efficient solvent evaporation and stable drying performance
• Flexible configuration allows customization of coating width, drying length, and process parameters
• PLC-based control system with touchscreen interface provides intuitive operation and real-time monitoring
• Robust mechanical structure ensures long-term stable operation in pilot-scale production

Main Specifications:

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

Application Areas:

• Lithium-ion battery electrode fabrication — pilot-scale slot-die continuous coating with segmented drying control
• Battery R&D — process development for new electrode formulations
• Small-batch pilot production environments
• Process development and optimization for various functional materials
• Continuous roll-to-roll coating applications requiring multi-zone drying profile control
• Research institutions, universities, and industrial R&D centers requiring pilot-scale slot-die coating capability

Recommended Operating Procedure:

1. Power on the XN-RTCA-300-3 and verify that the PLC + touchscreen interface, slot-die coating head, segmented drying zones, hot-air circulation system, edge alignment system, and unwind/rewind drives 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 unwinding shaft (max. Φ250 mm) and thread the substrate through the slot-die coating head, segmented drying zones, edge alignment system, and onto the rewinding shaft (max. Φ250 mm). 4. Configure the edge alignment system on the touchscreen to achieve the target ±0.5 mm alignment accuracy. 5. Set the target line speed (within max. 60 m/min) on the touchscreen. 6. Set the target wet film thickness on the touchscreen (typical minimum 5 μm; dry film thickness range 0–300 μm). 7. Set the target temperature for each independent drying zone on the touchscreen (within ambient–150 °C, ±0.3 °C per-zone accuracy) to define the optimized drying profile for the slurry chemistry being coated. 8. Allow the segmented drying zones to reach setpoints and stabilize. 9. Load the coating slurry, then initiate the run; the substrate advances continuously through the slot-die coating head and the multi-zone drying section, with finished material rewound on the rewinding shaft. 10. Monitor coating thickness, surface quality, edge alignment, drying residual moisture (target ≤1 μm), and tension during the run; adjust parameters as needed via the touchscreen. 11. After the run, allow the heating zones 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.

Packaging & Storage:

The XN-RTCA-300-3 ships fully assembled with the slot-die coating head, segmented modular drying zones (multiple independently controlled heating zones), forced hot-air circulation system, edge alignment system, unwind and rewind drives (max. Φ250 mm), PLC + touchscreen control panel, and pilot-scale modular frame (~L6440 × W1200 × H1960 mm). Install on a stable laboratory or pilot-scale production floor 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 (30 kW total power). 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 slot-die head, drying zones, edge alignment system, unwind/rewind drives, and PLC system periodically for wear or contamination.

Safety:

For research and industrial use only. Always follow standard safety protocols when operating pilot-scale coating equipment with heated surfaces and high power consumption (30 kW). Do not touch the heated drying zones, coated substrate, or hot-air ducts during operation — surface temperatures up to 150 °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, ensure adequate ventilation and exhaust extraction; consider pairing the XN-RTCA-300-3 with an NMP solvent recovery system, 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 all heating zones to cool to room temperature before any cleaning or sample-handling operations. Keep hands clear of the moving slot-die head, tension rollers, and unwind/rewind drives 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 setpoints in each zone, drying length, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific segmented transfer coating-and-drying protocols.
