Whitegold - Castings with emerald resin

[Christian K.]

Hello everybody!

I work in Austria, in a traditional workshop.
We startet with the Solus half a year ago.
Everything was new - New burnoud chedules, a lot of work bevore waxing the models up like curing and so on.

Especially whitegold with 15 to 20 % palladium is sometimes a problem. But we find a way to cast everything with plasticast.
Now we solved all problems - It makes me so happy that we no longer have any problems. Every casting is a success.

Here are pieces we made today :

No everytime i have the chance to help, i do.



The keys are :

o microwave prints after 30 min in UV oven (in water) 3 times à 3min at 750 Watt.
o the burnout
o the boric acid ( 2% in the destilled water).


Burnout:

10C° per minute to 150 C° and hold 2 hours

10C° per minute to 450 C° and hold 1H30min.

10C° per minute up to 800 C° and hold for 5 hours ( yes this is the key, that NOTHING is left and everything burns out !! )

Down to casting temperature.

flask 500 C°

thick parts 1200 - 1250 C°
normal peaces 1250-1300
thin peaces 1300-1330 ( not higher, otherwise the surface will get damaged

good luck

With a 10°C per hour ramp rate, it would take days to cast. Is that supposed to be minute?

[Christian K.]

oops, of course you are right . MINUTES
