Beschreibung
Zusammenfassung:	The invention provides an endoscopic video camera having a polymeric knob assembly, wherein the polymeric material used for manufacturing the knob assembly includes polyphenylsulfone resin, titanium dioxide, tin oxide, and colored metallic additives, is capable of withstanding sterilization, and has a metallic cosmetic appearance. The invention also provides methods of manufacturing the knob assembly by plastic injection molding processes, wherein undesirable molding characteristics are concentrated on portions of the knob assembly that are removed by secondary machining or post machining.
