Vacuum casting machines

Jewelry Discussion
1

I am interested in buying a vacuum casting machine. The choices have
confused the heck out of me. I would like to be able to cast
perforated flasks but I’m not sure if I really need that high-tech of
a machine.

Can the list make any recommendations?

Thanks!

Catherine, we use a MEMCO Electro-Vac daily and have had great
results over the past 5 years. We cast primarily 14K & 18K gold and
some sterling. We looked for a while and found this to be the the
best value.

    I am interested in buying a vacuum casting machine.  The

high-tech of a machine.

If you are doing small flask, smaller than say 2Dx3h, you don’t need
a perforated flask. My machine has just a flat table with a 1/4" hole
in the center for the vacuum, and a silicon rubber gasket. I have
cast flask up to 4’d with this. The one thing I do to prepare the
flask for the casting table is to carve a concave surface in the
investment and then carve a couple troughs that cross in the center.
That way, I get a “Pull” on the full surface of the flask, not just
where the vacuum hole happens to align with it. I mostly cast 14K
with only on or two pieces, and have had very good luck with this
setup. I think that doing large trees though that the perforated
flask is the way to go.

If you are planning on buying a vacuum casting machine, the less
expensive $800 approx. machines available from most suppliers will do
just fine. Perforated flask is not at all neccessary for any type of
castings asYou can see by visiting the "work shop " on the first page
of my website. Perforated flasks are much more expensive than
standard flasks . When you use the vacuum enhancers that are shown on
our website with standard flasks, you will get even better castings
and be able to put more flasks in your oven than is possible with
perforated. Spend your money on a good oven with accurate digital
temperature controls and a good oxy-propane torch. Check out the
casting section of my old workshop at

silver, brass/ bronze and pewter for people in the trade Daniel Grandi
