CrN PVD PVD plating method of mold using chromium nitride

摘要

The present invention relates to a PVD plating method of a mold using chromium nitride (CrN) that enables the life span of a mold to be extended by using chromium nitride coating after cutting the core wire of a mold for exterior products, comprising: 1 step of mounting an object on a jig; a second step of loading a jig into a closed chamber and depositing chromium nitride on the surface of an object in the chamber to form a film; a third step of extracting the finished product by wire-cutting the portion where the film is formed among a portion of the object in a specified shape; and, in the second step, covering the remaining portion except for a portion of the object with a protective material so that the film coating is protected from the surface of the object It can only be performed on areas not covered with ashes.
