Abstract
Method of manufacturing metal products from a powder (19) which is received in a mould cavity formed by a gas-tight casing (10, 11, 12, 13) and is isostatically hot pressed in the casing to form a monolithic body. A body (14) of graphite, hexagonal boron nitride, or another similar ceramic material is provided as a core in the mould cavity, and after the isostatic hot pressing this core is removed from the produced monolithic body by blasting.
