I would like to fold thin metal sheets to a particular angle.

For example: fold a 0.1mm thick steel strip of width 20mm and length 150mm to an angle of 45° along its length (10mm panels on each side of the fold).

I would like to keep the radius of the fold as small as possible, ideally on the order of the thickness or smaller. I would also like to do this on a bench top. I plan to use a range of thicknesses, up to 1mm thickness. But I am flexible on this constraint (but need to use thicknesses <1mm).

Are there any tools/machines which can do this in a repeatable way (ideally with 1-2° variation or less)? Are there any standards for this type of forming?

It sounds like you're looking for a sheet metal brake.

I'm sure you can find less expensive models elsewhere. Lots of places rent them too. Heck, with the thicknesses you're using, you can make one with some hardwood and hinges.

    $\begingroup$ I would just add, for the thicknesses involved, you could probably make your own bench top brake out of some hardwood, hinges, and some clamps. $\endgroup$
