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.
