Advance in fluidized bed coating: An experimental investigation on a performance polymer coating alloy

Abstract

An experimental analysis of the behaviour of a performance polymer coating alloy in a fluidized bed coating process was led. Major variables affecting coating thickness were analyzed and other variables as part-powder relative motion, part attitude, part location in the bed and bed density closer to the part were found out to deeply influence the performance of the coating process. Consistent trend in coating thickness and in roughness and waviness parameters were achieved varying process variables and a model, based on experimental findings, was stated as first support to coaters to best deal with the most part of operative variables of the coating process. © 2006 Elsevier B.V.
