What is the best book for learn to cut rubber molds?i have modelling in wax for jewelry,centrifugal or lost wax jewelry casting
Um. You’ve got Bovin’s “centrifugal or lost was jewelery casting”,
yet you feel you need more detail? There’s not much about mold
cutting he didn’t get into there, unless you want specific cutting
patterns for each and every individual piece of jewelry you’ll ever
find. It’s got more info there on mold cutting than I’ve seen in
all the other jewelery making books combined. what he doesn’t get
into much, are the more recent types of rubber, such as RTV pourable
silastics, or the vulcanizable silicone rubbers, or things like
Castaldo No Shrink Pink, and the like. But the use of these are more
requiring info on pouring, vacuuming, or vulcanizing the mold, and
some refinements, perhaps, to concepts around powder seperated mold
(the main one I can think of is to use brass mold locks, and then
mica powder instead of talcum powder, for powder separated molds with
the putty-like vulcanizable silicone rubbers, such as contenti
moldex, or the similar products from Castaldo and others. Mica
powder gives you powder separated molds that pull apart more easily
than with talc, which is a good thing with the silicones, since they
don’t have quite the tear strength of natural rubbers… But the
actual cutting of molds, is distinct from the vulcanizing or packing
or similar aspects of producing the mold before cutting it. And
Bovin pretty much hits all the bases I can think of there that are
worth putting in print. With that said, your other resourse is just
looking at molds cut by other mold cutters. Everybody works out
their own private little shortcuts and preferred tricks, and you’ll
learn something new with observation of any other mold cutters work.
You don’t even need to see them do it. Just look at the mold, and
what they’ve done…
