PIN HOLES USING A NYLON POWDER PAINT IN A FLUIDIZED BED
+++++++
Trying to help our customer with a low volume job, we are a powder and teflon facility and have never messed with a Fluidized bed set up before. The parts are small and are clean and Iron Phosphated we have heated them up to 250 degrees before dipping them and cured them for 15 min@ 350 any ideas would be greatly appreiciated.

Nylon would cover a fairly large range of powders, so I am not sure if my answer will work for you but you can give it a shot. We have done polyamide coating brand name Rilsan from Arkema very successfully. We pre heat the product to a temperature where there is no requirement to reheat the coating at all. It cures by its own heat content. Each product requires its own settings but once that has been done the results are repeatable. The coating in our case is 250 to 300 microns DFT. Best of luck.
