HOT ISOSTATIC PRESSING JIG AND METHOD FOR MANUFACTURING PARTS FOR USE OF IT

摘要

A hot isostatic pressing jig which improves dimensional accuracy during diffusion bonding of the bulk workpiece by allowing a bulk workpiece and a powder material received in the hot isostatic pressing jig to be held by a plurality of jig formed from dissimilar materials, and a method for manufacturing parts using the same are provided. A hot isostatic pressing jig(100) comprises: a can(120) in which a molding space(122) is formed to house a bulk workpiece(B) and a powder material(P) in the molding space at the same time; a shape embodying jig(140) which is charged into the can and comes into contact with the powder material to embody a complicated shape on a surface of the shape embodying jig contacting with the powder material during hot isostatic pressing of the powder material; and a restraint jig(160) which is charged into the can and comes into contact with one side of the shape embodying jig to restrain the shape embodying jig such that the shape of the shape embodying jig is not deformed during hot isostatic pressing of the powder material. The hot isostatic pressing jig further comprises a degassing tube(124) perforated into one side of the can to communicate the inside and the outside of the can with each other.
