Advice wanted on silicon molds for making wax patterns


#1

Hello folks,

I’m hoping you might be able to offer me some advice. I’d like to
start making my own molds for wax patterns. We’ve recently bought a
vacuum casting setup, and we have a wax milling machine, but I’m
learning to hand carve too, and I’d like the flexibility of having
an in-house method of producing copies of my originals. I’m not
talking about a moving all the work in-house, but I want the option
to be there. What I’m unsure of is which materials are best for doing
this - presumably silicon, but even then, there seem to be countless
formulations depending on the desired result. I also need some means
of getting the wax into the molds, and this is where cost really
kicks in - I need a cheap solution for this last part.

I’m looking forward to seeing what you can suggest. Apologies if
this message ends up badly formatted, or if I take a few days to
reply - Ganoksin seems to eat my messages in a very strange way, and
I only receive the daily digest sporadically!
