The present invention relates to a method and an apparatus for the production of cavity-free cast explosive charges of meltable crystalline explosives in casting moulds such as artillery shells. According to the invention the formation of solidification cavities in the explosive is prevented by warming the upper part of the casting mould with the aid of a casting funnel which is used during the casting and in which a heat-retaining medium with a high melting heat is provided in a space which surrounds the upper part of the casting mould. |
