you could make these with a hossfeld.
I am surprised nobody does.
The trick is finding the right round bar- I am pretty sure it aint A36 or 1018. And heat treat, if needed.
Because you want it annealed, to bend it like that, but then my guess is you want it hard, to stay that shape in use.
Dirt simple if you needed say ten thousand a month- you set up a big 4 slide, and you run em thru a tunnel oven.
But for a few, its fussy.
First, you need to find out how hard they are, and what alloy you can actually buy in that size wire, without having to order an entire mill run of 40,000lbs plus. The ideal stuff may or may not be available in 12' lengths.
Assuming you can find it annealed or half hard, you could easily wind these on a hossfeld, with a simple lathe turned die for the ID, two coils, one at each end of a piece, then bend the ends and center.
Then, heat treat or harden as needed.
Scale is hard to tell from your photo, but I am guessing maybe 3/16" in diameter, 1 1/2" coils, mas o menos?
I could do it, but I am too busy and you cant afford me. But you could do it, this is a simple bend on a hossfeld. Here is a picture of bending 3/8" round around a die that is maybe 3" OD. You can bend as many coils as you want, or partials. Its not hard, the leverage multiplier of a hossfeld makes it a one handed operation up to about 1/2" round, cold. But it does take some time. You can set stops, or just mark the material with a silver pencil.
however, my guess is you were hoping there was a cnc 4 slide somewhere that can just spit out 60 of these in a half hour- which, there may be, but its a half million dollar machine that takes several ton spools of wire, and its in a dedicated production line. Not many wire slide job shops left in the world- if they are, they are gonna be somewhere on the axis between Detroit and Providence, and most likely, not even gonna know what an internet is.
