Abstract
A method for producing a tandem sub for a perforating gun system includes positioning an electrically conductive signal bar in a central passage of a tubular housing of the tandem sub, and injecting a mold material into an annulus formed between an outer surface of the signal bar and an inner surface of the tubular housing that sealably adheres to both the signal bar and the tubular housing.
