There are a few hobby injection molders available:
Both sell an "empty" mold frame that can be used with epoxy or a 3d printed mold. So I was toying with the idea of getting one.
I understand how a 2-piece mold works for something like a head, but how is something with an internal cavity like a boot injection molded?
I know molds can be made with more than two pieces, so they can be taken apart to remove the product, but I don't see how the toe of a boot wouldn't be trapped inside.
Is a boot made in two halves and sonic welded together? Or does it use rubbery material so it can be pulls off the mold?
