A method of curing a polymeric binder onto a powdered metal after such polymer has been coated on the powdered metal but before a part is therefrom molded, thereby forming a polymer matrix-powdered metal composite material. The polymer-coated powdered metal may be cured by retaining the polymer-coated powdered metal in a fluidized bed contained within a fluidized bath (e.g. a fluid bed coater/drier apparatus) even after the coating process has terminated. The temperature of the fluidized bath may then be raised, in turn raising the temperature of the fluidized bed, thereby curing the polymer onto the coated powdered metal in situ. By keeping the polymer-coated power metal in constant motion during the curing process, the polymer-coated powdered metal particles do not agglomerate nor otherwise adhere to other coated powdered metal particles.
