Abstract:
A manufacturing process for a grille element of a media playback system is provided. In one embodiment a sheet of plastic is thermoformed into a desired shape. Holes may have been drilled into the sheet of plastic prior to being thermoformed. Once thermoformed into the desired shape, a coating is applied and cured via a subsequent heat treatment process that anneals the material to remove additional stresses in the material from thermoforming. Once formed and heat treated, the formed component can be bonded to profile substrates to help maintain the formed desired shape.
