Oct 01, 2004· Rector: With fluid bed coating, the part has to be preheated, immersed in the coating and then flowed out. Long: Electrostatically assisted fluidized bed coating does not dip the part into the powder, it generates a cloud of charged particles (much like a conventional electrostatic gun) through which a heated or an unheated part passes. It generally applies a thin coat vs. the thicker coat
Piper uses PVC Powders in its Fluidized Bed Coating process. PVC POWDER (Vinyl, PVC, or polyvinyl chloride) is a coating material that can be applied to any substrate that can withstand the process temperature of about 400F. Piper applies it using the fluid bed method. At the process temperature, the powder fuses into solid Vinyl.
FLUIDIZED BED POWDER COATING Fluidized Bed Powders are applied by dipping heated metal parts in an aerated powder bed .

Fluid bed coating is generally thicker than an electrostatic powder coat and is, in many ways, a simpler more consistent process. Because the surface of the bed is simmering, if a precise dip line is required, then the parts will need to be masked. STRENGTHS: Fluid bed powder coat can give a thicker coating than electrostatic spray.
Fluidized Bed Parts are dipped into epoxy powder that is suspended in an air contained, aerated hopper. This is accomplished by releasing compressed air through a porous plate located in the bottom of the hopper. As result, the epoxy powder floats in the hopper in a fluidized state. This creates a smooth, continuous epoxy powder
