Tom,
I think I may have missed the earlier parts of this thread, so I do not
fully understand your requirements. One solution we have used for
parts in small quantities that would normally require a pattern set to
be made, is to use the Sand Sintering process. We find most foundries
have no problem with this, because you supply the full sand set and
they just pour it. No draft angles required.

As I understand, ductile iron, is done more commonly in sand casting.
The
patterns need to be either designed for that process, or converted into
patterns that would work, as a matchplate for instance. Most sand
casting
foundries aren't geared towards prototype work though. That is the
process I
would investigate rather than investment casting.
