Transported by LTL Freight (Truck)

Product Options

Coating Head:


MSK-AFA-300 is a Roll-to-Roll continuous coat with 3 optional coating heads for materials research labs.   
This system integrates the functions/ features of reeling in & out, slurry feeder, coating blade, baking oven, and final electrode winding (reeling in).
It can coat electrode sheets up to 250mm in width and 500 meters in length automatically. 
For Roll to Roll Coater Service, please fill out and submit the Roll to Roll Coating Service Request Form

Note 1: MSK-AFA-E300-UL is updated from MSK-AFA-E300 with all UL certified electric parts from June 1, 2014, which are ready to pass UL or TUV test at extra cost. 
Note 2: Starting July 10th, 2015, the "Intermediate Coating" mode will be offered on all units as standard features.
Note3:  upgrade to three coating heads optional

              For bilayer slot die coating, please consider the customized slot die head with dual channels:

Max. Coating Width


Thickness adjustable range

0 - 5mm

Coating thickness (after drying)

5 - 200um (for most kinds of battery electrode coating material)
Note: The dried coating thickness results vary depending on the physical property of the coating material.

Thickness Precision

± 3µm (± 5µm at edges)

Coating Speed

0-750 mm / minute 

Max. Drying Temperature

150°C, temperature accuracy: ±1°C

Customized design of dual heating chambers is also available:

Heating Zone Length

710mm (28")

Reeling/Unreeling Shaft

  • 75mm (ID)
  • The alignment control is built-in with +/- 0.5 mm via an optical sensor.
  • The tension control:  20 - 80N adjustable

Max. Reeling/Unreeling Roll Diameter

250mm (OD)

Max. Coating Length

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

Slurry Stirring

SS316 Moving Rod

Exhaust Port Size

127mm O.D

Control Panel

  • Touch screen control panel, which controls the slurry feeding rate, coating speed, and heating temperature.

Compressed Air

0.5-0.8 MPa Air compressor is required,  but 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.

Slurry Feeding Pumps 

  • Normally slurry viscosity for doctor blade, reverse comma blade, and slot die is suggested in the range of 2000-6000 cps. For microgravure coating, the slurry viscosity could be 50-2000 cps. 
  • As for doctor blade, reverse comma blade, and microgravure, peristalic pump of MSK-155 with 2L volume or MSK-156-E can be considered:
  • As for slot die, syringe pump of MSK-151-L500 with either 500 mL or 1L and screw pump of MSK-156 can be considered for continuous and intermittent coating, respectively:



  • You may order  Dual-Filtration System for NMP Vapor and connect it to the coating system for keeping environmentally healthy. Please click Pic.1 for details.
  • Atmosphere plasma cleaning add-on for the substrate is available upon request. Such a surface treatment will activate and increase the energy of the substrate surface and thus enables a better adhesion & bonding to the coating materials. Please click Pic.2~4 and Video.1 for more details.
