Established in 1992, the Evansville Operations was the original IET operation and the beginning of the Integrated Energy Technologies vision.

Using diffusion bonding and internal cooling geometries, Evansville built jet engine exhaust nozzle components for the F-22 Raptor fighter that could withstand heat in excess of 3000 degrees Fahrenheit. Building on that success, the military business continued to grow for other combustor components and high-temperature applications. The Evansville facility currently supports several systems on the Joint Strike Fighter program.

Today, Evansville manufactures high-temperature components such as industrial turbine engine combustors, rear support covers, main combustors, augmenter liners and an ever-growing list of components from materials such as high-temperature super alloys, titanium alloys, nickel and steel. The manufacturing methods employed include diffusion bonding, robotic welding, and, five and six axis cutting and machining. In addition Evansville offers numerous support services designed to take your project from conception to production.

We offer more than 55,000 square feet of capacity in our ISO 9001/AS9100 certified state-of-the-art manufacturing facility located in Evansville, Indiana. If your application requires advanced cooling methods, interior structure elements, or parent metal properties, the Evansville team can assist you.
