The Ohio State University turned to Switzer for a higher degree of precision.
The Aerospace Research Center at OSU developed a groundbreaking double-sided, high-density heat flux gauge to be used in rotating turbine rigs. To produce the gauge, the design called for Kapton® polyimide film between two metal masks. Due to the small size and precision requirements of the masks, laser etching was not a viable option. Having previously worked with Switzer, OSU was confident that we would deliver the right solution.
To bring this never-before-seen design to fruition, Switzer used photochemical etching for exceptionally tight tolerances on .003 in. thick stainless steel. Furthermore, the front and back masks had to accurately align to create a small passage. Our team ensured the design was executed to specification, as well as expedited the production of four masks to be used in two different gauge types.
