Inside the Part: Aerospace Gearbox Casings
A closer look at one of our recent projects.
We manufactured these aluminium gearbox casings for use in an aerospace application, with the final application kept confidential.
This was a great example of how much goes into a precision component beyond the machining itself.
The parts were machined from aluminium 6082 T6, then went through non-destructive testing, Alochrom treatment, masking, primer and a matt black painted finish.
We also completed full inspection reporting and First Article Inspection documentation to support the quality requirements of the project.
It is a good reminder that a finished component is only part of the story. The planning, inspection, finishing and paperwork behind it matter too.
We have shared a more detailed article on the website for anyone who would like to see the full process behind the part:
