Knife Coater

The knife coater is used for thick film coating. The coating method here involves, with a backup roll, a knife roll, a liquid dam, and a pump, controlling the coating thickness by adjusting the gap between the backup roll and the knife roll.

Features

  1. Thick film coating with a wet thickness of 30 to 450 µm (This machine is dedicated for thick coating and is not suitable for thin coating).
  2. The film thickness distribution can be ±2% or less.
  3. The coating thickness is easily controllable by adjusting the gap between the backup roll and the knife roll.
  4. The method is exclusively for high-viscosity coating liquids (Coating is not available for low-viscosity liquids).
  5. The roll has a rotational runout accuracy of 3 μm or less.
  6. A small amount of liquid is used, allowing easy cleaning.
