Abstract

This invention relates to a mould assembly for a hot isostatic pressing, HIP, process for fabricating a component, comprising: a first part which includes a shaped surface for forming a first surface of the component, the shaped surface having at least one recess; a second part arranged to move relative to the first part during the HIP process so as to compress a powder in-fill held therebetween, wherein the second part includes a formation configured to focus pressure toward the recess so as to aid consolidation of the powder in-fill at a distal end thereof.
