Hello Joan,

We presently cast CoCr alloys for land-based turbine blade components. The
CoCr alloys would not present us with any technical problems. We would love
to cast medical/human body implants as we have not had a previous
opportunity to do so.

I suspect that such applications may require the foundry to have product
liability insurance and we do not, nor could we afford such coverage given
our size and current product mix. However, we could produce the castings,
perform all testing to ensure the parts meet their specifications, but we do
not presently have a products liability policy.

If an opportunity in this area was large enough, we would most definitely
add a products liability policy to cover us if it were required to secure an
order. However, the business opportunity would have to be sufficiently
large enough (financially) to justify the cost of the added coverage.

Our starting point for quoting and manufacturing of prototypes is a 3D CAD
.stl file.
