Abstract
A delay detonator made from an inner and outer casing combination which rces the number of individual components. The detonator uses reduced volume with increased pressure to permit control of the pyrotechnic delay mix. The amount of free space to start combustion is limited as compared to previous delay detonators. An overlapping lip arrangement of the inner and outer casing and an inner sleeve permit welding at the outer edge to permanently lock the distance between detonator components.
