Method And Device For The Electrophoretic Production Of Sheet-Like Blanks From A Metal Slurry Or Ceramic Slip

摘要

The invention makes it possible to produce very thin ceramic blanks as a precursor for ceramic discs, for example for use as faces in wrist watches. On the other hand, the production of metal blanks for use in CAD/CAM machines is possible with the invention. Both methods are based on depositing the material from a slurry or slip by electrophoresis. The essence of the invention is the isolation of the peripheral region of the precipitation electrodes that is produced by a non-conducting frame. This allows the precipitated mass to be easily lifted off from the precipitation electrode. The subsequent sintering with a possibly proceeding machining operation allows precision articles to be produced.
