  • Method of manufacturing metal- or ceramic microparts
    Publication number: 20050140070
    Abstract: In a method of manufacturing metallic or ceramic microparts using a three-dimensional body formed by first and second polymer fractions in a two-component injection molding process, wherein one of the polymer fractions comprises an electrically non-conductive polymer and the second an electrically conductive polymer, the polymer fraction used for the first injection molding step has a higher melting point than the polymer fraction used in the second injection molding step and the metal micropart is formed by galvanic deposition of a metal from an electrolyte and the ceramic micropart is formed by electrophoretic deposition of ceramic material from a ceramic suspension or colloid on the electrically conductive polymer fraction surface of a substrate surface of the interim body.
