1. An orbiting scroll of a scroll compressor comprising:
a longitudinal axis; and
a platter wall having a first face including a spiral structure projecting therefrom disposed along the axis, the platter wall having a second face disposed along the axis including a coupling structure configured to couple the orbiting scroll to a drive mechanism of the scroll compressor and a circumferential surface connecting the first face to the second face in the axial direction of the platter wall about a periphery of each of the first face and the second face, the orbiting scroll including a first mass reduction feature provided as an inwardly indented channel formed in the circumferential surface, the channel being disposed along the circumferential surface respectively spaced apart from both the first face and the second face, wherein the channel forms a retaining feature configured to retain a rim of a mask therein, the mask configured to mask at least a portion of the circumferential surface of the platter wall when the rim thereof is retained within the channel.
