<p>A method of manufacturing mouldings by isostatically compacting powdered material in a deformable capsule. The capsule is assembled from preformed sub-elements, is filled with powdered material, is evacuated, is essentially gas-tightly sealed and the capsule containing the powdered material is isostatically compacted into an essentially dense body. The invention is characterized in that at least one sub-element (21) is preformed by compression moulding of thin sheet with recesses (22) and that the sub-elements are joined together, by means of welding, into a capsule (20), wherein, after the joining, at least one of the recesses in the preformed sub-element forms a mould (23) for a moulding part and at least one additional recess in the preformed sub-element forms an inlet channel (24) for the powdered material.</p> |
