Oh, you are generating a 3D groove. I got it now. I thought you generated it flat and then formed the plate in a press.

That's not a bad idea, but I liked having one side contoured to match the kettle and the other flat for a good seal with the fittings.

You could spot face the outside for the fittings?

If someone was going to make a bunch of these, that would be the way to do it and keep the price down. I don't have the capacity to form metal. (I do mostly CNC milling and some small CNC lathe work.) But that is a good approach.

Hmm, I happen to be a stamping die designer. 
Could design up a tool to mass produce from a coil of what ever steel you want. The only problem is to make that tool you are looking at about $30,000.00 and then you need a press to run it.

And you'll need a different one made for each size kettle and pot . . . . .

I would donate my time to design it.

That's an easy one. The form station/s would be a quick change system that you could make to swap-out, run a batch of one size, swap, run another batch size and so on.
Maybe you would end up with 10 to 12 quick change forms to cover 90-95% of kettles on the market.
