The Fuel Nozzle & End Cover assembly is a complex and high precision part composed of more than 200 components that are made from bar stock, plate, pipe, forging, casting and precision machined parts. It requires all capabilities in-house, including machining, EDM, welding, assembly, NDT, and functional test.
We employ cutting-edge 5-axis vertical machining centers, 3 and 4-axis horizontal and vertical machining centers, and CNC lathes to produce these products. Our plant facility is certified to AS 9100D and ISO 9001:2015. A host of special processes are available in-house to ensure quality and shortened lead times. They include:
- Heat treatment (Nadcap certified)
- Testing- CMM/Hardness/Flow test/Hydrostatic
- NDT (Nadcap certified)- FPI/MPI/LP/Borescope/UT
In addition to part production, we also provide customized MRO services, including:
- Repair of end covers and fuel nozzles
- Modifications of end covers and fuel nozzles
