I looked up the equipment to achieve this and it was very expensive.
Fluid bed powder coating. Typical thickness for this method ranges from 007 025 with no drip activity. To get the best results with powder paint the paint needs to be fluid meaning that it should be fluffed up with air to give a thinner more consistent coat of paint. The object is then submerged in or in the cloud just above the fluidized bed of powder. A fluid bed allows powder paint to be suspended in air to approximately twice its normal volume inside the units interchangable cup.
In fluidized bed powder coating heated parts are either dipped directly into a container of fluidized powder or passed through an electrically charged cloud of powder which is created above a container of fluidized powder. This is not an ironclad rule and you can certainly achieve both of these results with either coating technique. Fluidized bed powder coating consists of immersing a hot part into a bed of powder allowing the powder to melt on the part and build a film and subsequently providing enough time and heat for this film to flow into a continuous coating. Here is a link to the fluid beds in use https.
Electrostatic spray coating is extremely good for applying relatively thin and consistent film thicknesses. Quick tutorial on how to build inexpensive and easy fluid beds for powder painting jig heads and other lures. Depending on requirements the product properties can be influenced and enhanced. By fluidizing the powder quality and control of the paint application are greatly improved over trying to dip into stagnant powder.
The powder melts and forms a coating onto the hot surface. I found a few videos that explained how they have created their own fluid beds. However fluidized beds are an older way of applying powder coatings and though they are probably not as widely used as they once were they are still in use today. In the fluidized bed application method the object is pre heated to a temperature above the melting point of the powder.
