METHOD OF MAKING HOLLOW PARTS BY HIPING WITH MANDREL PLACED OUTSIDE THE CAN

摘要

Manufacturing irregular shape parts is one of the outstanding advantages of hot isostatic pressing. Hollow parts, with tubes as their main representative, are one of the important irregular shapes. The method described in this paper can be used for manufacturing hollow parts with exactly controlled inner diameter and improved roundness and straightness.rnWith properly selected gap between mandrel and can. property anisotropy can be improved or "end cover effect" can be overcome.
