Abstract: The invention relates to a process for realizing the running-in of a fluid comprising at least an explosible component sensitive to shocks and/or rubbing.The process of the invention consists in filling the moulds 2 with a specified quantity of casting powder P, in running-in a casting solvent S into the moulds 2 placed under reduced pressure, and in then curing the blocks thus cast to gel the casting powder. The running-in of the casting solvent S into the mould 2 from the storage tank 3, and the beginning and the end of this running-in of the casting solvent are controlled by controlling the pressure difference existing between the pressure prevailing in the storage tank and that prevailing in the mould 2. Thus, it is possible to control the running-in of the casting solvent into the moulds remotely.The present invention applies especially in the industry for the manufacture of solid propellant compositions.

Abstract: A method and a mould for manufacturing articles of compacted powder by isostatic compression of powder in a mould, which is made of flexible material of substantially constant thickness and is substantially barrel-shaped, the mould having at one end a bottom made integral with the rest of the mould and being adapted to be closed by a separate plug at its other end.
