Quality control and final test

Coatings in the Bead Coating Mode are often used in in- dustry to apply film thicknesses in the range 5–300 µm, where speeds from 0 to 300 m/s are common. If there are fluids with high viscosities, the coating of thin films at high substrate velocities causes specific problems. By using low-pressure chambers in the back part of slot dies, in- stabilities can be controlled by changing the pressure level (Po-Pu) between the front and the back of the die lips.
