Oh OK, thank you for the differences, that helps. I'm looking to
make shallow boxes, no deeper than an inch, and would be OK with
some curvature on the bottom. I would like to be able to press a
pattern in the top of it as well. Could I press the box and then
have a shallow sillouette die and repress and get the pattern in?
Boxes can have tops but there usually called lids.
Can be just an interference fit over an internal strip or flange or
hinged with or without a catch or lock.
it all depends on what you are making the box for, from what metal
and what price you think you can get for it…
As for pressing a design into the top or lid!! yes that can be done
with a 2 part hardened tool steel die one a positive, usually set up
in the uppermost part of your tool set and the negative replica of
the positive in the bottom.
you register the sheet accurately!! in between the 2 dies and apply
Thats effctively doing repusse all in one go.
Taking this technique as far as you can go is coining to proof
For that you need hundreds of tons of load.
Really big kit to do this type of work, with a factory to put it in,
but great to use.
This is in the realms of a fully industrialised setup.
