Can a 2" dia disk with a 1/8" flange all around be created in sheet metal?
Can a 2" dia disk with a 1/8" flange all around be created in sheet metal?
This was done with a sheet metal ring around a perforated base extrusion. Not perfect, but reasonably close.
If you start with a round sheet metal base flange of 2" you can create an edge flange from the circluar edge on the outside of the piece. You will have to make sure that your bend radius is smaller than the 1/8" edge that you are wanting to add. Attached is an image of what I think you are asking for. Hope this helps.
Edge flange in SW2011 now works for non-linear forms
The Sheet Metal part would have to be manufactured with a press like a pop can.
