Variable Coating Machine

The adjustable coating machine forms a uniform coating on the substrate by adjusting the blade gap and speed. It is used in laboratories to simulate coating processes of different thicknesses and is suitable for surface treatment tests of materials such as paper and films.
Selection
When selecting, consider matching the substrate width with the machine specifications, ensuring the coating thickness adjustment range meets experimental needs, pay attention to the corrosion resistance of the blade material, note that the motor type affects speed stability, and ensure the cleaning design facilitates switching between different samples.
