I recently took the plunge and bought casting equipment incl. mold
making equipment to try to mass produces some of my filigree. I cast
filigree about 12 years or so ago, with reasonable results. I’m
using bellicone red mold compound and Rio’s precision pink, but I’m
not happy with the results so far. Earlier, I used dark blue
plast-o-wax which tolerated being pulled out of the mold better. The
results I"m getting so far are inconsistant. either it’s not filling
the whole pattern, or I’m getting too much flashing, or it is
breaking on removal from the molds. I’m about to call Rio and order
some plast o wax, but I’m not totally sure that is where my problem
lies. My injector is a hand pump model which is wide open and the
nozzle is on the top of the pot and must manually be pushed down to
draw wax up from the bottom of the pot.
any suggestions would be appreciated.
