How This Slot Die Coating Machine Works
Step 1: Substrate Loading
First, you load the substrate (aluminum foil for cathodes or copper foil for anodes) onto the unwinding station. The machine accepts widths from 100mm to 320mm.
Step 2: Coating Method Selection
You select the desired coating method:
- Doctor blade coating for simple continuous coating
- Slot die extrusion with die head and screw pump feed for precision patterned coating
Step 3: Parameter Setup
You set the coating parameters via the control system:
- Coating thickness: 8 – 400μm
- Coating speed: 0.1 – 1.0 m/min
- Coating pattern: Continuous, gap, stripe, or grid
Step 4: Precision Coating
The substrate passes through the coating head. The slot die coating system applies slurry with ±2.5μm accuracy, ensuring uniform thickness across the entire 300mm coating width.
Step 5: Drying
The coated electrode enters the 1.0m drying oven with hot air circulation at up to 150°C (±5°C uniformity) . Solvent is removed efficiently, preparing the electrode for the next stage.
Step 6: Rewinding
After drying, the finished electrode is rewound onto a roll, ready for calendaring and assembly.
Applications
