The present invention relates to a method of manufacturing an article. The method comprises forming a sealed shell of gas impervious material, the shell comprising a collapsible hopper portion opening to a main body portion. The main body portion and at least part of the hopper portion contain a powder material. Next, the method comprises applying vibratory energy to the shell and powder material to move the powder material from the hopper portion to the main body portion and to compact the powder material within the main body portion. Finally, the method comprises subjecting the shell and compacted powder material to isostatic pressure to consolidate the compacted powder material within the main body portion to form the article. |
