Precision dip coating does not like the vibration of a liquid surface because it is often pulled up at a low speed. If vibrations occur around the liquid tank while pulling up from the tank, it can cause uneven film thickness on a coated material surface.
[Case studies of vibration control measures]
Vibration sources that affect a coating liquid in the tank, such as pumps and exhaust blowers, are identified and vibration control measures are applied.
