The invention relates to a process for the manufacture of an explosive ammunition component with controlled fragmentation, comprising a charge of solid explosive contained in a metal casing internally clad with a sleeve externally provided with indentations. A rigid sleeve made of plastic or elastomer, externally provided with indentations and which has a form of a vessel provided with a single opening, is produced first of all, and then this sleeve is introduced, with the bottom first, into a metal casing comprising an opening and whose shape and dimensions are such as to allow the sleeve to clad the casing internally. A pasty or liquid explosive composition is next cast into the sleeve and the composition is then solidified.
