Slot-Die Roll to Roll Coating System ( Max. 250mm Wide) with Precision Slurry Feeding Pump - MSK-AFA-SD300

Please email for lead time
Item Number: MSKAFASD300
Transported by LTL Freight (Truck)


MSK-AFA-SD300-UL is a CE Certified  and UL inspection ready automatic slot-die coating system with a compact footprint that is less than 6'x3'. It is perfect for making uniform coatings from 1~300 micron thick.

For Roll to Roll Coater Service, please fill out and submit the Roll to Roll Coating Service Request Form.


Working Voltage

208 - 240 VAC, 50/60 Hz, Single Phase 

Max. Power Consumption

5 KW ( 50A Air breaker required )

Slot Die Coating

The slot die is perfect for uniform film coating of 1 micron and up to 300-micron thickness. By changing the shim size with various patterns, you would be able to produce continuous, intermittent, or even grid coatings that match the shim patterns. Please refer to the pictures in below for more details:


Slurry Feeding Pump

  • MSK-156 slurry feeding screw pump with 4 liters tank is included
  • 24DC Input, 500W
  • 0.5~0.8MPa compress gas is required.
  • Slurry feed rate: 0.1 - 150 rpm (or 0.023 - 34.5 mL/min)
  • Stirring speed: 27 rpm

Shim (Spacer)

0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm & 0.8mm thick shims are included for producing films with various thickness.

Tip: The thickness of the shim determines the slot opening of the die and thus has major impact on the final coating thickness. The rule of thumb is that thinner shim will produce thiner film, vice versa. 

Max. Coating Width

250 mm

Max. Coating Length

Depends on the coating and substrate thickness. Typically, 10um thick foil with 100um coating can get 600 meters of electrode length coated per run.


Coating Speed

0-800 mm / minute 

Minimum Thickness & Precision

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 1-micron level film is achivable for all kinds of slurries. For further discussion, please let us know your slurry specs and coating thickness requirement.

Max. Drying Temperature



Forced convection hot air  (IR + UV heating is available upon request)

Temperature Accuracy


Heating Zone Length

710mm (28")

Reeling/Unreeling Shaft

75mm (ID)

Max. Reeling/Unreeling Diameter

250mm (OD)

Compressed Air

0.5-0.8 MPa (Air compressor not included. Please click here to order)
Attention: If a gas cylinder is used instead of air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator.

Optional: NMP and Slurry Filtration System

  • You may order  Dual-Filtration System for NMP Vapor (Pic.1) and connect it to the coating system for keeping environmental healthy.
  • You may order the Magnetic De-ironing Filtration system (Pic.2) for optimizing the battery electrode slurry condition before the coating process.
