I'm looking for anyones expertice on burnout of green carving wax and mold making. I realize this is quite a large area so I will attempt to narrow this down to specifics. Dan, I hope your there.
What is your de-wax and burnout cycle? Does it differ for
Does it make any difference if you remove the wax from the
oven ( via wax tray ) before going to red heat ( i.e.smoke)?
What is the most succesfull metal to cast in terms of less
What is the most successful size flask ( I have a ney
centrifuge) to assure a better casting for the model you just
spent two weeks carving?
What is your favorite mold rubber? I’m a tad lost on the
many differences of rubbers ( although I can recommend a great
prophylactic )- no shrink, silicon,latex etc. I find the silicon
gives a great finish o n the wax yet loses on the flexibility of
the mold. Does a super shiny wax model a better casting make?
What is your favorite injection wax?
Here I’m really in a jungle.
- When is one supposed to dust the mold with talc and when to
spr ay with silicon? It is my understanding that vent lines are
supposed to be kept open with talc and that silicon should not-
to prevent them from clogging. Fair enough, but I can’t see how
the parting lines wouldn’t accumulate this gunk after every
subsequent talcing and spraying of silicon. Also, after I dust
the mold and shoot about 4 waxes until the models start coming
out clean, I get about 2 good waxes before I nee d to dust the
mold and repeat the process. Is this " normal "? Any replies are
greatly appreciated, Peter Slone
