FLUID BED

FLUID BED

Fluid bed application is used to apply thick film builds ranging from a minimum of 6 mil up to as much as 40 mil or more. Fluidized powder beds (tanks) consist of two-chambers separated by a porous plastic membrane. The lower chamber is the supply air plenum, the upper chamber holds the powder. When low pressure air is applied to the plenum, the powder fluidizes, i.e., it is lifted and acts like a fluid that parts can be dipped in. The parts are pre-heated prior to dipping so the powder immediately melts and flows. Excess powder is shaken or blown off and returned to the bed. A lip vent or cartridge style powder collector is typically used to capture blown off powder or powder drifting off the bed surface from the fluidizing air.
