Jim,
Does anyone out there want to share their secrets for getting molds to fill correctly? Sometimes I spend all day wax injecting and don't get any wax models made. It is getting frustrating.
If you are still have problems pulling a wax from your mold after
all the great advice you have already been offered I would like to
suggest one more thing you might try.
I just made a mold of a very thin ring mounting that had been
causing problems. I had very good success using Castaldo’s Titanium
Label rubber and adding their Golden River wax additive to my wax
pot.
This might just do the trick for you.
Good Luck
