a method for electroforming and electrodischarge machining uses , an electrically conductive thermoplastic wax composition which can act as an electrode on which a metal article may be electroformed and as an electrode mount for the metal article to be electrodischarge machined . the electrically conductive thermoplastic wax composition comprises a thermoplastic wax material and very small spherical particles the surface of which have been treated to make them electrically conductive . the electrically conductive thermoplastic wax composition is easily separated from the metal articles formed by electroforming or electrodischarge machining by heating to melting temperature and / or by use of a suitable solvent for the thermoplastic wax . in this way , the composition may readily be recovered for repeated reuse in another electroforming or edm process , and accurately formed finished articles having intricate shapes and close tolerances can be produced . in a preferred embodiment , the spherical particles are silver coated solid glass microspheres comprising 60 to 75 percent , by weight , of the overall thermoplastic wax composition .
