Its Electronic Systems arm builds high-reliability interconnects, circuit board assemblies and integrated systems in high-mix, low-volume runs, while Structural Systems makes large contoured components and assemblies through forming, chemical milling, machining and finishing. It also lists engineered products such as RF solutions, motors and resolvers, and brands including Nobles Worldwide, BLR Aerospace and Lightning Diversion Systems.
