Platinum casting?


#1

Hi John Have you had any experience with PT90/Palladium 10%. This is
the alloy I use for casting and I achieve sensational results. What
is your comment.

Hi Doug I too cast Pt using the Manfredi induction machine and I am
achieving great results. I am very interested in the same day
service that you do. I have read about it in the AJM magazine, but
being so far away here in Australia it is very hard to get the
correct investment etc. Are you willing to share some of the
"secrets" with me ? What investment do you use and where is it
available ? What is the exact casting method you use (eg flask
burnout, sprue technique etc). I have tried using different alloys
and am now using Pt90/Pd10. i found that the cobalt alloys were much
to inconsistent in cast quality. I would appreciate some feedback.

thanks and regards
David Gabriel

Hi darcy; Unfortunately it isn’t possible to cast platinum without
special equipment due to the extreme tempurature and the fact that the
platinum will freeze before it fills the flask. you need a more
powerful centrifuge as well as high temp.investment ,not to mention
experience through much trial and error.If you are handy to the west
coast (Vancouver ,Canada) I can give you the address and phone # of
Tony Loy at images .He is the best locally ,if not,the only one doing
platinum in this area.He has better results than some of the bigger
outfits with their high tech ,expensive machinery, because he has
better control with the torch .let me know if your interested.

To any interested Orchidian, Check out Revere Academy’s Platinum
casting class. Ed Friedman teaches platinum casting using a simple
centrifuge. See class description at www.RevereAcademy.com

Hi all: I think that if you search the Orchid archive you may find
contributions from Ed Friedman of the Revere School, who has worked
out a way of casting some platinum on a regular horizontal
centrifuge. As I remember there are some limitations as to what can
be done, but it is possible to cast platinum this way.

What I am wondering is if there is some method which will work using
vacuum casting for platinum.

David, Although I regularly work with a fantastic 18kw fabricating
alloy made of 75% pure gold and 25% palladium I have not worked with
the palladium platinum alloy you mentioned. Therefore I have no
comment but I would be interested to hear more about your results. Is
your opinion based on your casting experiences or based on faster
finishing time setting ability etc.? Another concern I have had in
regards to this specific alloy is the color. My 18kw mix is very dark
and that is part of its advantage. I don’t think this would be as
desirable in platinum. And finally with the price of palladium being
so high is this alloy going to cost me more?

    I may be making a ring which requires a platinum setting for a
diamond. I don't have platinum casting equipment, and had a couple
questions: 
(2) If the above is totally out of the question, does anyone on the
list provide services for a fee that I could send a wax model to, and
get a platinum head back?

Darcy, you may have found someone to cast your platinum for you, but
in case you haven’t, here’s another option. James and Larry of
Outcast in Seattle, WA do great work. They have no minimum order,
and they will do everything from casting, and doing a certain amount
of finishing on, a whole production run of thousands of pieces, to
just making you one mold to take away and cast from yourself. In
addition to casting for jewelers, they have also cast chess pieces,
parts for vintage cars, switchblade parts for antique Italian
stilettos, and bit and spur parts. A typical mold for a ring runs
about $25, then they charge by the injection for the wax, and by the
tree for casting. Recently, they have added platinum casting to the
usual repertoire of non-ferrous metals (precious and non-precious).

If you want to see examples of some of the work they have cast, go to
Guild.com and look up Gina Pankowski’s fabulous work. Outcast
doesn’t have a website, and they have never advertised their services
because their work is so good that they get plenty of customers just
by word of mouth.
