ABSTRACT:
An electroforming apparatus, in particular for the manufacture of CD/LD data media molding tools, comprises an anode assembly and a rotatable cathode assembly spaced therefrom, and a stationary nozzle means for ejecting an electrolytic fluid into the space between the anode and cathode assemblies. An annular part of the cathode assembly surrounding a molding tool blank is penetrated by a plurality of circumferentially distributed flow passages, the inlet ends thereof are disposed to successively come into alignment with the nozzle means upon rotation of the cathode assembly so that the electrolytic fluid ejected from the nozzle means is received by the flow passages and guided thereby into the space between the anode and cathode assemblies. The width of the spac can thereby substantially be minimized.
