H-J Enterprises is a manufacturer of electrical components, including transformers, bushings, electrical connectors and brass and bronze castings.

H-J offers on-site machining and assembly of all castings and connectors, plus in-house tin plating.

This allows the company to hold shell-molding tolerances with a green sand cost.
