Abstract
A quasi-isostatic pressure-forming methods for the production of precision explosive charges consists of the pre-heating of the explosive mass to be pressure-formed is now preheated to 100-120.degree. C. with subsequent forming in an autoclave at pressures of an order of magnitude of 3500 bar during 0.5-5 min. After pressure relief during a further phase of 10-180 min, the mass is cooled down at pressures of 50-500 bar. In a further elaboration of the invention, two autoclaves, one high pressure and one low pressure, may be utilized.
