Abstract
A method for making miniature explosive powder charges or other compressible materials, including providing a material to be compressed into multiple cavities of a rigid platen, and positioning an elastic platen in contact with the rigid platen. The elastic platen is mounted in a head assembly having a pressurizing fluid. Evacuating the cavities and the material contained therein, and trapping fractious particles and vapors out-gassed from the material. Pressurizing fluid, which causes deformation of the elastic platen to form distensions that project into the cavities and compress the material into compacts. The pressurizing fluid is depressurized enabling the distensions to retract and the elastic platen to return to a non-deformed state. Finally, separating the elastic and rigid platens and collecting the compacts, which may be miniature explosive charges having an optimized density.
