I saw one at an exhibition this week. I was particularly impressed
by it melting and pouring under vacuum, it did not pour from any
height though,. The samples they had looked good. You do need a good
water supply, 8CMH vacuum, argon gas supply, and a 16 amp, 240V power
supply. I was told you could cast in a day because the flasks were
quite small and burnt out fast. I would like to know if they need
much maintenance. They have a good video on their site.
I was looking at other dental casters and came across these.
Try dental casting suppliers, they seem to be ahead of the game
