Versatile Roll to Roll coating Machine

The AS-MSK-AFA-MC400 R2R Coating System revolutionizes precision thin-film manufacturing with modular flexibility for battery electrodes, flexible electronics, and functional coatings. Engineered for R&D and pilot production, this system supports slot die coating, doctor blade, and micro gravure methods, delivering ±1μm coating uniformity. Featuring a multi-zone convection drying oven with gradient temperature control (up to 200°C) and optional NMP/emission monitoring, it ensures solvent-free, crack-resistant film curing. Customize coating modes (continuous/stripe/grid) and integrate slurry feeding or solvent recovery systems for sustainable, high-throughput processing. Ideal for lithium-ion battery anode/cathode R&D and perovskite solar cell prototyping.

Core Capabilities:

1. Modular Coating Heads:

   • Slot Die Extrusion: Closed-loop positional control (±5μm) for slurry isolation

   • Transfer Coating: Adjustable comma blade (electric height control) with 0.1mm accuracy

   • Micro Gravure/Tape Casting: 10-200μm wet thickness range

2. Advanced Drying Solutions:

   • Convection Oven: 1-3 zones, 1-2m length options, double-sided airflow

   • Gradient Baking: Independent PID-controlled zones (RT-200°C) to prevent film cracking

   • Curved Drying: Optional IR-assisted curing for heat-sensitive substrates

3. Process Automation:

   • PLC/HMI Interface: Recipe storage, tension control (0-300N), and web alignment (±0.2mm)

   • Intermittent Coating: Programmable start/stop cycles via pneumatic valves

4. Emission & Safety:

   • NMP Concentration Monitoring: Real-time VOC detection (0-500ppm)

   • Solvent Recovery: Condensation + activated carbon adsorption (95% efficiency)

Technical Specifications:

• Coating Width: 50-400mm (adjustable)

• Line Speed: 0.1-3m/min (servo-driven)

• Slurry Viscosity: 100-50,000cP

• Substrate Thickness: 5-500μm

Applications:

• Lithium Battery Electrodes (NMC, LFP, Silicon Anodes)

• Flexible Displays & Printed Electronics

• Photovoltaic Backsheets & Barrier Films

Optional Modules:

• MSK-156 Slurry Feeding System (10L capacity)

• In-line Thickness Gauges (β-ray/Laser)

• AI Defect Detection Camera
