Auxiliary Power Unit Exhaust Liner for the Aerospace Market

APU Exhaust Liner
APU Exhaust Liner

The auxiliary power unit exhaust liner shown here is an example of a product that we produce on a regular basis here at Precision Metal Products. Measuring 20" in diameter and 48" in length, materials of construction included 347 stainless steel sheet and bar, felt metal, thermal blanket, and B-seals. We fabricated multiple sheet metal details using roll forming, brake forming, and metal spinning processes, which kept tooling costs and lead times to a minimum. After laser or machine trimming, we welded the components per AWS D17.1, installed the blanket, and riveted the B-seals into place.

Our experience and agility enabled us to complete this project in 30 days. The high quality craftsmanship is what makes us an industry-leading turnkey solutions provider to the aerospace market. To learn more about this project or our diverse range of services, contact us today.
