Abstract (en)
[origin: EP0034232A2] A method of manufacturing a slip ring including the steps forming a body (2) of plastics material, forming a plurality of grooves (6) in a surface of the body, treating the grooved surface to allow a metal skin (7) e.g. copper. to be deposited thereon by an electro-less plating process, electro-less plating a layer of base metal (7) on the treated surface of the plastics material, including the grooves (6) formed in the plastics body, removing the plated material (8) from between adjacent grooves to define individual tracks of the slip ring and electroplating the plated material to overlay the grooves only with a layer (9) of a noble metal e.g. gold.
