Abstract
Methods for making extrusion dies using a LIGA process, a German acronym for lithography (Lithographie), electroplating (Galvanoformung), and molding (Abformung), are described. The resulting extrusion dies can be used, for example, for extrusion of cellular ceramic substrates, precision extrusion of optical fiber or optical fiber precursors, or other applications where profile extrusion requires high dimensional precision and/or has otherwise intricate patterns.
