Powder paint fluid bed problems. Air blowing large holes through powder surface. 1 poor charging inadequate powder build or wrap on part. Fluidized bed powder coating is a process where a pre heated part is dipped into a tank of fluidized thermoplastic powder which is typically pvc or nylon. With a fluidizing bed powder that is too fine can cause irregular coverage.

Check high voltage source is on. Four chamber fluid bed for powder painting. Systematically check electrical continuity from voltage source to electrode grid including cable resistors and fuses1. With electrostatic spray processes one needs to monitor kva humidity grounding issues powder delivery issues gun maintenance and replacement of wear parts.

Keeping a close eye on the powder levels and the actual amount of powder on the bed is a smart idea. It is very difficult to achieve a thin coating consistently. Film build generally occurs rapidly over the first five mils. If the powder due to reclaiming or efforts on the manufacturer s part is too fine it can cause all manner of trouble.
