Power & Voltage

• Voltage: 208 - 240 VAC, 50/60 Hz, Single Phase
• Power: 4 kW
• Circuit Breaker >= 20 A
• Option: 110VAC is available via a transformer
• The power cable is included, but not plug for 208 - 240 VAC. 

Slot Die Heads

• The slot die head is made of stainless steel (SUS630)
• Max. coating width: 180 mm
• Continuous coating head or multiple strips coating head selectable
• Slot Die Coating Head Adjustable: Vertical, 45 degrees inclination, and Horizontal;

   

Shim (Spacer)

• 0.1mm, 0.2mm, 0.3mm, 0.4 mm, and 0.5mm thick shims are included for producing films with various thicknesses.
  
• 
• Tip: The thickness of the shim determines the slot opening of the die and thus has a major impact on the final coating thickness. The rule of thumb is that thinner shim will produce the thinner film, vice versa. 
  

Unwinding Roller & Substate

• Unwinding Roller: Diameter: 200 mm; Width: 230 mm
  
• Substrate for the roll to roll coating
• Inner diameter: 75 mm
• Outer diameter: Maximum 150 mm
• Width <= 200 mm
• Thickness: 6-30 um

Coating Length

• The coating length depends on the coating width and thickness.
• For example, If 30 mm width and 0.2 mm thickness, the coating length can reach 15 meters by a 100 ml pump.

Coating Speed

• 0 - 0.5 m/min adjustable via the touch screen control panel

Coating Thickness & Precision

• Single-layer coating thickness: 5 - 300 micron, which is decided by slurry viscosity, feeding speed, and the gap between slot die and substrate.
• The end-user has to practice to find the best parameters.
• 1 µm ±1% ( dried film )

Attention: The final coating thickness is dependent on a wide range of parameters such as slurry viscosity, solid particle size, solid content, shim thickness, foil rolling speed, and slurry feeding rate. Therefore, we are not able to guarantee that a 1-micron level film is achievable for all kinds of slurries. For further discussion, please let us know your slurry specs and coating thickness requirement.

Slurry Feeding

• Syringe pump automatic feeding
  Volume: 10 mL / 20 mL / 30 mL
• Feeding speed: 0.01 - 10 mm/s
• Large syringe pump with 500 mL or 1L or screw pump with 4L are also available upon request (optional)

Heating & Drying

Reeling/Unreeling

• Reeling/Unreeling shaft: 75mm (ID), which is a mechanical expanding shaft
• Reeling/Unreeling Roller: 150mm OD
• Reeling/Unreeling Roller is precisely tension controlled, 20 N Maximum

Control Panel

• Touch screen control panel, which controls the slurry feeding rate, coating speed, and heating temperature.
• The control unit can be separated from the coating machine for remote control.
• The coating unit could be placed in the glove box with Argon atmosphere

Corona Treatment (Optional)

The corona treatment for substrate is available upon request

 

Glovebox Integration (Optional)

If the slurry for coating is air/humidity sensitive, the glovebox can be integrated with the roll-to-roll coater

Compressed Air requirement

• 0.5-0.8 MPa (Air compressor not included. Please click here to order)

             

      pic1                                          pic2

Optional:

• You may order Dual-Filtration System for NMP Vapor (Pic. 1) and connect it to the coating system for keeping environmentally healthy.
• You may order the Magnetic De-ironing Filtration system (Pic. 2) for optimizing the battery electrode slurry condition before the coating process.
•  Atmosphere plasma treatment is available upon request. The plasma treatment could activate and increase the energy of the substrate.
• Power: 2 kW; Maximum 200 mm width plasma treatment
