An electronic device includes a housing, a printed circuit board (PCB) disposed in the housing, and electronic components that are supported on the PCB. The housing is an assembly of a cover and a base. At least one of the cover and the base include a region in which at least a portion of an outer surface of the housing within the region, and a portion of housing material adjoining the portion of the outer surface, have material properties that are different than those in other regions. A method of manufacturing that provides the desired material properties is also described.
