Vesna Cotta informed me of the page http://www.dynamictooling.com that has info
on Dynamic tooling. Also Alan Lightman sent me the following:
As I understand the process, PolySteel is a steel with binder mixture
(90:10) which is poured into a plaster mold made off an RP master. The
material is then forged to form the final steel shape, burning off the
binder and consolidating the powder. It differs from Keltool and
RapidSteel
in that it does not use an infiltrant to achieve full density, rather
the
powder is compressed as it is heated. There are many advantages to
this
process. The final material is more akin to tool steel but with
advantages
over what you would obtain if you had machined the part from a wrought
billet of steel. PolySteel is commercialized by Dynamic Tooling, which
is
located, I think, in Fresno, California. I hope that this helps.
Thankyou to both of you for your help, and I hope this aids anyone else
