METHOD OF MANUFACTURE OF ELECTRIC DETONATORS

摘要

FIELD: mechanical engineering. SUBSTANCE: a section of a thin-walled tube with delay compound is inserted on the detonator sleeve to the cap delay element through a fill of ignition compound; the tube section is placed in a polymeric shell and crimped; the thin-walled tube is obtained by rolling of band first into a chute through which the delay compound is poured in, and then the chute wells are bent under, and the whole tube is moulded. EFFECT: enhanced stability of time delays.
