Small Roll to Roll Slot-Die Coating System (Max. 160 mm W ) with Slurry Feeder - MSK-AFA-SD200-LD

Small Roll to Roll Slot-Die Coating System (Max. 160 mm W ) with Slurry Feeder - MSK-AFA-SD200-LD

0.0/5 rating (0 votes)


MSK-AFA-SD200-UL is a small slot-die coating system with selectable coating width from 30mm to 160 mm.  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.


Power Requirement

  • Voltage: 208 - 240 VAC, 50/60 Hz, Single Phase 
  • Power: 2.1 KW ( 15 A Air breaker required )
  • Option: 110VAC is available via 3 KW transformer  ( 20A breaker is required)
  • The power cable is included, but not plug for 208 - 240 VAC.  

Slot Die Head & Coating Width

  • The slot die is made of stainless steel (SUS630) for coating thickness from 5μ to 300μ.
  • The slot die head is selectable at 30, 50, 100, and 160 mm.  Please inform us before purchasing
  • Note: 
    • 30 - 100 mm coating width is achieved by changing the shim size on 100 mm wide slot die head

Shim (Spacer)

  • 0.1mm, 0.2mm, 0.3mm, 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. 

Syringe Pump

  • One 100 ml syringe pump, made of stainless steel, in a built-in coating machine for feeding slurry
  •  Slurry feed speed: 0.05 - 5 mm/s adjustable via the control panel
  • 250 ml syringe pump is available upon request at the extra cost.

Coating Length

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

Coating Speed

  • 0- 800 mm / minute  adjustable via the control panel

Coating Thickness & Precision

  • Coating thickness:   5  - 300 micron, which is decided by slurry viscosity, feeding speed, and the gap between slot die and substrate.   You have to practice by yourselves to find the best parameters.
  • 1 µm ±1%  ( dried film )
  • Optional:  Automatic alignment control with +/-0.01 accuracy at the extra cost

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.


  • Heating method:                    Forced convection hot air  (IR + UV heating is available upon request)
  • Max. Drying Temperature:     150°C
  • Temperature Accuracy:           ±1°C
  • Temperature uniformity:          ±5°C


  • Reeling/Unreeling shaft:         75mm (ID), which is a mechanical expanding shaft
  • Reeling/Unreeling Roller:        200mm (OD)
  • Reeling/Unreeling Roller is precisely tension controlled, 10-400N

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.

Compressed Air requirement

  pic1                pic2

Substrate Requirement

  • Substrate thickness: 8 - 30 µm
  • Substrate width: 150 mm max
  • Substrate roll: 200 mm max.


  • 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.
  •  Pic.1       Pic.2
