What mold to use for a bellow?
Hello
I am pretty new to 3d printing and have never done any (injection)molding before. I would like to mold this with walls of between 2-5mm at home: https://imgur.com/a/l66RWwI
What shape/type of 3d printed mold would you suggest me to 3d print for this? I was thinking about some kind of recipient which has this shape: 1 larger and one a bit smaller (e.g. 2 mm smaller), so I can pour the product in between the two recipients. But then I have no clue about how you would unmould all of that to recuperate your actual bellow.
The shore hardness of this bellow will be somewhere between A20 (like a rubber band) and A60 (like a tire), don't know exactly yet. I will have to try a couple of things and see what suits best.
I know in some cases people build collapsible molds to be able to easily unmold afterwards. But I am not sure here what type of mold I could use and thus would be the best suited.
Any suggestions would be more than welcome!
EDIT: I am working with silicone, not plastic
