Injection-Molding Apparatus for Attaching End Fittings to Detonating Cords.

Abstract

The patent application relates to a method for attaching a typical end fitting arrangement which includes a sleeve-like bearing member receiving an end of the explosive cord and a coupling member, such as a threaded nut, slipped axially over the cord into a fixed position relative to the sleeve. To securely bind together the cord and the sleeve, a void is provided radially inwardly of the nut and a thermosetting material is directly injected into the void to flow over and around the components. Upon hardening, all components are locked together as an integral body. The injected material further provides a significantly-improved hermetic seal. Special thermosetting materials having short glass fiber fillers are used to assure load-bearing strength.
