As a spin off from a jade carving project, I’ve developed a complex
surface that I wish to press into metal.
Problem is, I can do this on one surface of a die, but it will be
difficult to do this on 2 halves of a die. So, the thought was
raised, lets use 1/2 of a die, and press into urethane or other
material to provide hydraulic back pressure.
Any suggestions on materials to use? I have a 15 ton press, so
should be adequate for small 1 square inch) surface areas.
