A while ago someone posted some pictures of forming a shape by pushing metal into a mold with a lump of gel and a press. What was the process called? I would like to find the thread and a bit more information.
I want to form flat elliptical aluminium name tags onto a cylinder. They are Delco-Remy generator and starter tags for The McKinnon Industries.
I have now found it is called hydroforming with fluid or rubber-pad forming with "rubber", probably urethane. Thank you. I have found Gary Ash's posts etc.
So if I use rubber pad forming and I want to fit 0.6 mm aluminium onto a 4.5" diameter cylinder, how much elastic rebound should I expect? i.e. how big should the cylinder be? I expect it would be a little less than 4.5" dia..
