Hydroformed 347 Stainless Steel Plenum Housing for the Aerospace Industry

Plenum Housing

Our ability to create geometrically complex parts that meet the stringent requirements of the aerospace industry won us the contract for producing the plenum housing shown here. Using a hydroforming process enabled us to create the complicated configuration and abstract geometries with precise detail. We laser trimmed the formed tubes to size, machined the flanges, and built a special fixture to orient the components, which allowed for the creation of distortion-free welds according to the ASW D17.1 standard. Fabricated from 347 stainless steel to withstand prolonged heat and resist corrosion, the finished housing featured dimensions of 12" in length x 8" in width x 8" in height. Visual and CMM inspection confirmed that we satisfied the ±.004 tolerance requirement, and penetrant testing validated the integrity of the welds.

This plenum housing met the customer's high expectations for both performance and quality, and we currently manufacture 30 units/year. At Precise Metal Products we specialize in high precision products such as this.
