Hi Don,

You perhaps already know that ref but, just in case, here's the link to How Bells are Made -How it's Made :
Jingle Bells machine making starts at 1'15" .

Like you, I also think that there is a lot of testing to get a good looking result.
And the resulting blank shape would probably not suit press forming process, 3 steps press mold bending.

Where you thinking of designing blanks for a mold to make some jingle bells ?

Happy Holidays !

Thanks for the link to the video. I always enjoy seeing the manufacturing process.

No, I was not thinking about making bells. I just stumbled across the image I shared in the original post and wondered if MoI or one of the other CAD apps I use could form it. I thought that if any could, it would be MoI.

Hi Don,

Here are 2 other interesting links to Jingle Bells making, this time traditionally forged :

I don't think it would be possible to use the blank used as ref to get the bell shaped in one step in Moi as it doesn't take into account the 2 steps process to make the bell.

The 3 Youtube refs, either by machining or handforging, treat the bottom and the "petals" part separately, in order to prevent stretching the "petals" while constricting the center part.
In the Flow process, the blank is stretched all the way to the top and gets elongated.

We would need to take the "plasticity" of the metal blank into account.
