The minimum distance (A as “28 – t – half of slot hole” = 28 – 10 - 7.5 = 10.5) may depend on the followings.
- bend radius (R)
- thickness (t)
- material
- manufacturer’s quality and experience
However the best way may be to drill the holes after bending unless the A is greater than 2~3 times R and A is greater than 2~3 times t (from my experience).
