We may be able to help you get to a metal composite casting. We have
never tried such a thin wall before but it should work with our process.
We may be able to run a small test sample if you are interested.
Another approach is centrifugal investment casting...I'm not sure what
the minimal wall thickness is (used for dental implants). Also, are you
sure you don't want to form sheet metal to create the geometry?

Good Luck, and please let me know if you find a source for very thin
walled castings.
