METHOD FOR MANUFACTURING ULTRA-FINE PIPE UNIFORMLY CUT IN LENGTH DIRECTION THROUGH PHOTOSENSITIZING AND ETCHING PROCESSES AND ULTRA-FINE PIPE UNIFORMLY CUT IN LENGTH DIRECTION MANUFACTURED BY THE SAME

摘要

PURPOSE: To provide a method for obtaining an artifact precisely cut to a constant length without mechanical processing by passing a long electroformed artifact obtained through electroforming through photosensitizing, exposing and etching processes, and a ultra-fine pipe uniformly cut in length direction manufactured by the method. CONSTITUTION: The method for manufacturing ultra-fine pipe uniformly cut in length direction comprises an electroforming process of growing a long rod shaped electroformed artifact by performing electroforming on a core material; a process of coating a photosensitizer on the long rod shaped electroformed artifact; a process of forming an exposed part and a non-exposed part on the photosensitizer coated artifact by irradiating light onto the photosensitizer through a film; and an etching process of performing etching on the non-exposed part. The ultra-fine pipe uniformly cut in length direction is characterized in that it is fabricated through an electroforming process of growing a long rod shaped electroformed artifact(17) by performing electroforming on a core material, a process of coating a photosensitizer on the long rod shaped electroformed artifact, a process of forming an exposed part and a non-exposed part on the photosensitizer coated artifact by irradiating light onto the photosensitizer through a film, and an etching process of forming an etched part(19) by performing etching on the non-exposed part.
