An extrusion process for manufacturing powder coating compositions is disclosed. The process generally includes a shear mixing step done at ambient temperature and a focused heating step in which the shear mix is heated to a higher temperature for a shorter time than in conventional methods. The focused heating provides for a shorter heat history, resulting in enhanced coating properties. The mixture may be cooled before it leaves the extruder.
