Surface treating method of extrusion die and Extrusion die |
| abstract |
The present invention relates to a surface treatment method of an extrusion mold and an extrusion mold manufactured using same. The present invention has excellent mechanical physical properties and removes a process of pre-heating the extrusion mold before an extrusion process. The surface treatment method of an extrusion mold comprises: a first step of making an inner space of a chamber vacuous; a second step of inputting a gas; and a third step of forming a nitride layer on a surface of the extrusion mold. |
