A customer of mine is working on some designs for combining cast
components with blanked-and-fabricated parts, and since the blanked
parts are copper, they want to cast the other parts in Cu as well.
So, since I have never cast copper, and none of the places I used to
work at did either, and I can’t recall any of the casters I knew or
know doing it either, I have to ask. Obviously pure Cu castings are
going to be weak, and will tarnish quickly, so I understand why
they’re not widely used for structural jewelry components, but these
of my customer’s will be decorative, not ‘functional’, so if they
find someone to do it, it should be ok.
I do, however, want to learn more about the possibility from the
people here; what do we/they need to look out for ?. Tips and/or
tricks, etc. ?. Any input is welcome, since, as I said, I’ve got
basically nothing right now.
