Slot-Die Coating System XN-SDC

Name: Slot-Die Coating System XN-SDC

Equipment Type: Integrated Slot-Die Coating System with Extrusion Feeding Pump, Dual Vacuum Chambers & Heating Platform

Product Code: XN-SDC

Product Introduction:

The Slot-Die Coating System XN-SDC is designed for precision coating of battery electrodes, solar cell materials, OLED functional layers, and other thin-film materials. The system integrates a slot-die coating head with an extrusion feeding pump, dual vacuum chambers, and a heating platform in a single PLC-controlled platform, enabling uniform and controllable film formation on flat substrates. The XN-SDC is suitable for laboratory research, material development, and pilot-scale process validation, particularly for applications requiring tight thickness control (±3 μm in 1 μm increments) and elevated-temperature coating conditions.

Main Features:

• Slot-die flat coating — high coating uniformity and excellent thickness consistency across the substrate
• Integrated extrusion feeding pump — stable material delivery without pulsation or material breakage; syringe capacity up to 50 mL, feeding speed 0.05–5 mm/s
• Dual vacuum chambers (upper and lower) — improves substrate fixation and coating stability; chamber size ~L415 × W200 × H30 mm
• Independent heating platform — ambient–130 °C with ±1 °C control accuracy for uniform temperature distribution during coating
• Precise doctor-blade gap adjustment — 0–5 mm range with ±3 μm thickness accuracy in 1 μm increments
• Motor-driven substrate transport — adjustable coating speed 0.5–20 mm/s
• Compact structure with refined industrial design — suitable for laboratory environments (~L580 × W420 × H370 mm, ~65 kg)
• PLC and touch-screen HMI control — convenient parameter setting, storage, and operation
• Customizable coating width — standard 300 mm, other widths available upon request

Main Specifications:

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

Application Areas:

• Battery electrode precision coating — slot-die coating with stable extrusion feeding for laboratory and pilot-scale cell development (lithium-ion, solid-state, sodium-ion)
• Solar cell materials — uniform thin-film deposition for solar cell research, including perovskite and organic photovoltaic absorber layers
• OLED functional layers — precision functional layer coating for organic electronics research
• Other thin-film materials requiring slot-die coating with controlled temperature conditions
• Laboratory research and material development — formulation screening and process optimization
• Pilot-scale process validation — transition from benchtop coating to production-scale slot-die deposition

Recommended Operating Procedure:

1. Place the XN-SDC on a stable laboratory benchtop or workstation with adequate working space and good lighting; connect the power supply per local electrical standards (1.5 kW). 2. Power on the XN-SDC and verify that the PLC + touch-screen HMI, slot-die coating head, extrusion feeding pump, dual vacuum chambers, motor-driven substrate transport, and heating system are all operating normally. 3. Place the substrate (foil or sheet-type material) on the lower vacuum chamber platform and engage the upper and lower vacuum to fix the substrate firmly. 4. Mount the syringe (max. 50 mL capacity) loaded with the coating slurry into the integrated extrusion feeding pump; ensure no air bubbles are trapped in the syringe or feeding line. 5. Connect the syringe outlet to the slot-die coating head inlet. 6. Set the target doctor-blade gap (within 0–5 mm) on the touch screen, with thickness accuracy ±3 μm in 1 μm increments. 7. Set the target substrate transport speed (within the 0.5–20 mm/s coating speed range) and target feeding speed (within 0.05–5 mm/s plunger speed) on the touch screen. 8. Set the target heating temperature on the digital temperature controller (within room temperature to 130 °C, ±1 °C accuracy) and allow the heating system to stabilize. 9. Initiate the coating run; the extrusion feeding pump delivers slurry to the slot-die head while the substrate transport advances the substrate at the configured speed. 10. After the run, allow the heating system to cool before removing the coated sample. 11. After each run, clean the slot-die head, syringe, feeding line, and all wetted surfaces with appropriate solvent (water or NMP, depending on the slurry system used) and dry thoroughly before the next run. 12. Inspect the slot-die head, vacuum chambers, motor drive, feeding pump, and heating 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 (especially the motor-driven substrate transport) 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 slot-die head and inspect the slit opening for wear or contamination affecting film thickness uniformity
• Periodically inspect the vacuum chamber seals to ensure consistent substrate fixation
• Periodically inspect the heating platform and temperature sensor for accurate temperature control

Packaging & Storage:

The XN-SDC ships fully assembled with the integrated slot-die coating head, extrusion feeding pump, upper and lower independent vacuum chambers (chamber size ~L415 × W200 × H30 mm), motor-driven substrate transport, doctor-blade gap adjustment mechanism, heating platform with digital temperature controller (ambient–130 °C, ±1 °C), PLC + touch-screen HMI control panel, and standard syringe (up to 50 mL capacity). 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 the slot-die head, syringe, feeding line, and all wetted-surface components, dry thoroughly, and store in a clean, dry environment.

Safety:

For research and industrial laboratory use only. During operation, do not insert hands or any other body parts into the moving syringe plunger, slot-die head, motor-driven substrate transport, 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 platform, vacuum chambers, 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. When handling pressurized slurry in the slot-die feeding line, ensure all connections are properly secured before initiating the coating run; line rupture under pressure can cause splashing of slurry or solvent. 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.

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