Hi everyone, allow me introduce myself. I’m a working structural engineer that has been working on an idea for a few months. It has taken me from buying a 3d printer to casting aluminum in my backyard. I have finally gotten my idea to “work” but now am in desperate need of manufacturing advice.
Here is my question:
How are double-walled stainless steel items produced? Examples of this would be a double-walled steel thermos (not vacuum sealed) and double-walled stainless steel bowls.
Deep draw? Metal spinning?
I thank everyone in advance, need to figure this out to move onto the next step.
