Slot-Die Coating System XN-SDC – Integrated Extrusion Feeding Pump, Dual Vacuum Chambers, 130 °C Heating, ±3 μm Accuracy | Xnergy

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, enabling uniform and controllable film formation on flat substrates. The XN-SDC is suitable for laboratory research, material development, and pilot-scale process validation.

Product Features:

• Supports slot-die coating processes with high coating uniformity and excellent thickness consistency
• Integrated extrusion feeding pump ensures stable material delivery without pulsation or material breakage
• Dual vacuum structure (upper and lower vacuum) improves substrate fixation and coating stability
• Independent heating control system ensures uniform temperature distribution during coating
• Precise adjustment of coating gap and coating speed to meet different material requirements
• Compact structure with refined industrial design, suitable for laboratory environments
• PLC and touch-screen HMI control allow convenient parameter setting, storage, and operation

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
• Solar cell materials — uniform thin-film deposition for solar cell research
• OLED functional layers — precision functional layer coating for organic electronics research
• Other thin-film materials requiring slot-die coating with controlled drying
• Laboratory research and material development
• Pilot-scale process validation

Recommended Operating Procedure:

1. 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. 2. 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. 3. 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. 4. Connect the syringe outlet to the slot-die coating head inlet. 5. Set the target doctor-blade gap (within 0–5 mm) on the touch screen, with thickness accuracy ±3 μm in 1 μm increments. 6. 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. 7. 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. 8. 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. 9. After the run, allow the heating system to cool before removing the coated sample. 10. 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.

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, 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, clean the slot-die head, syringe, feeding line, and all wetted-surface components, dry thoroughly, and store in a clean, dry environment. Inspect the slot-die head, vacuum chambers, motor drive, feeding pump, and heating 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 platform or coated substrate during operation — surface temperatures up to 130 °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 fume hood and follow local regulations on solvent use and recovery. 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. Keep hands clear of the moving syringe plunger, slot-die head, and motor-driven substrate transport 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, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific slot-die coating-and-drying protocols.
