What the heck is a fluidized bed?

This is a common question and one that we happily answer all the time.

Basically, a fluidized bed is a container of powder that has air blown into if from the bottom.

This air makes the solid powder "fluidize" or act like a liquid. Piper typically fluidizes both PVC and Nylon powders in a multitude of colors, and we have some experience with other materials as well.

Using this technique, we are able to put beautiful plastic coatings onto sheet metal and wireforms.

This process can work on any substrate that can handle temperatures around 400°F.

Because of the nature of the fluidized bed, it is much more difficult to achieve a well defined "dip line" on parts processed this way, than it is with other techniques such as dip coating. Therefore, most of our fluid bed work is done on products that need to be fully coated.

Something to consider when employing this process is that the part being coated needs to he held in some fashion while it is beich submerged in the fluidized bed.

Typically, there is a small blemish, which can be "repaired" or sealed in post processing, when this process is performed.
