Will,
Call Chris Kambouris at Wisconsin Engraving.
The do some pretty remarkable work in transferring geometry like that to
steel tooling.
Thanx and good luck,

Subject: cast stainless or be-cu mold inserts
esteemed colleagues-
i have a client that has a perfect application for a cast mold insert.
the part in question contains shapes that are best taken directly from a
sculpted prototype (a leaf and vine garden motif), however, their last
experience with a beryllium-copper insert was not good. they found a void
in the tool that ultimately caused them to lose sales to a small customer
called wal-mart. bad problem. i've explained that if folks like solidiform
can cast parts for f-16's, then certainly it is possible to cast a mold
insert that doesn't have unwanted porosity, but the decision makers are
nervous.
now, i know all the pitfalls of investment casting mold inserts,
especially in aluminum. shrinkage, shrinkage, and shrinkage. so, what i
want to hear is names of suppliers who work in stainless who have experience
and could potentially help my client. this is a relatively low tolerance
application, but the inserts are quite large (the part is 9" x 4" x 14") and
will be multi-cavity. material is polypro or polyethylene, half a million
units per year.
