Abstract
The present invention is directed to a method for production preformed fabrication casing or associated parts intended to generate fragments initiated by the explosive of contained warhead charges. Molded parts having fragmentation bodies (4, 21, 34) embedded therein are produced by a two-stage powder compaction method followed by sintering together the compacted powder metal. The method described in the present invention defines how in an initial stage the fragmentation bodies (4, 21, 34) are fixed in position using a fixture (2) after which the bodies are covered with powder metal that is then compacted until the powder forms a single molded part (2) after which the fixture is replaced with a secondary quantity of powder that is also compacted to form a self-supporting unit (12) together with the first quantity of powder.
