Many components and processes are involved in the casting
production. All parts of the process are important to assure the final casting
is of high quality.
While, of course, we do all of our casting
in-house, it is interesting to discuss the details of the processes involved in
the jewelry casting procedure. It is the most important
part of the process, and shows our knowledge and careful attention to detail
which is our hallmark. | Part 2
| Quality Control check: A careful quality control check is performed on the waxes, including the sprues, trees and if
applicable bases, to assure no item has been overlooked during the wax making
process. |
 Inspecting a wax |
 Cleaning a wax |
| Investing: After our careful check the next
procedure is to create the investment cast from the wax. At this stage cleanliness and attentiveness to detail is most important to assure a superior
cast. |
Materials: We only use high-grade investment which is mixed only at the instant of use. This assures the purity of the investment
mix, and like all our procedures is carefully monitored during the mixing
process. Proper investing is essential for proper casting outcome.
Vacuuming: Once mixed, the investment
is poured into the mold containing the waxes, where it is then pressure-vacuumed
to remove air pockets and other gaseous impurities from the mix. Care is taken
to vibrate the mold to assist in the removal of all air bubbles, and of course
this process, like all of our others, is human monitored. |

| Burnout: The vacuumed flasks are then transferred to our
computer-controlled ovens, where the molds are high temperature baked to set the
investment and melt the wax. We oven process all of our molds at night, to
assure adequate time for proper mold setting without disturbance or risk of
interruption. |

| Casting: Usually the next morning the flasks are ready for casting in our state-of-the art
casting machine. Inert gases which cover the precious metals during the casting process prevent the metals from oxidizing during the casting process. Thus, this process this will assist in a cleaner casting which will require less time in the finishing and polishing stages. | <<PREVIOUS
