One observation I make right away is there's no lid.. Obviously when things go well there's no problem but when things go wrong, which they will do, you could be in trouble. One of the main things that can go wrong are things like a cracked crucible or you simply try and cast to many pieces at one time and over fill the crucible.. Casting is an experimental process that takes years to learn. Everything from making masters, rubber mould making, sprue trees etc etc have to be learned through experience. When you're working with molten metal 1000c you can't take any chances or you'll end up in A&E.

Hi, great video! How often do I need to season the crucible? Only once, when it's new? Or before every casting? And how to adjust the flame for Co-Cr (dental) alloys to avoid overheating? If you could describe it (length of the flame, colour...) Thanks
Hi There, Thank you for your questions. We asked our Jewelry Tech Team, this is what they had to say: "The crucible only needs to seasoned the first time. Over time and use, the flux may start to chip so touch-ups may be needed, but a full seasoning is only needed on new crucibles. We're not sure if melting Cobalt Chromium alloys is possible with a standard jewelers torch. Because the melting temperature is so high, a hydrogen torch would most likely be required but we cannot say for sure. An induction casting machine would be the best option. Since Cobalt Chromium is a dental alloy, we would recommend contacting a dental laboratory to see what process they use for casting that alloy." Thanks again for watching; hope this helps!
Hi there! Thank you for reaching out. This is a great question. In regards to some of the differences between the two methods of casting, weighing these variables will help you select the best one for the type of work you do : -If you are using a torch to melt the metal, both casting methods will give very repeatable and very comparable results. -Centrifugal casting can give slightly better and crisper details due to the energy generated during the casting process. Spin casting can also fill slightly finer details like filigree a little better. - Units like the Vic 9 only draw from the bottom of the flask so they can have more difficulty filling finer detail on larger thin items. - Units like the Vic 12 that use the perforated flasks draw a vacuum from all directions and, therefore, have better filling capabilities. These units also may have a larger vacuum pump to help draw the metal into finer areas. Larger vacuum pumps generally work better with perforated flasks. - Both systems work fine for both yellow and white gold. You should not really see any difference between vacuum and spin casting, as far as quality goes. High nickel white gold is just kind of a pain to cast. - One big difference with vacuum casting is you can pour larger amounts of metal when using an electro melt. These units melt the metal in a more controllable environment and hold the metal temps more accurately. This can lead to better castings without overheating the metal. The flask does start to cool as soon as you turn the vacuum on. It starts drawing room air into the core of the flask so you want to pour as soon after you get a full vacuum as possible. The longer the flask sits with the vac on and running, the faster it starts to cool the core of the flask. Since the investment is a great insulator, the core temp of the flask doesn’t drop too quickly until the vacuum is turned on. Once you turn the vacuum on, it starts dropping quite quickly but you need to give it a few seconds to fully evacuate the air before you pour. We hope this helps! Let us know if there's any more information we can provide for you!
Si estás usando moldes de hule convencional del usado para vulcanizado llantas.....este tiene unas propiedades increibles,se toma el mold y se ahoga en petroleo durante 24hs.el molde se incha y el grabado crece un 500/100,aumentando tambien el grabado que tenga,despues con parafina sacamos una copia aumentada considerablemente a un costo infimo.proceso "jonapru",es libre intentelo xfa.
Hello there, this machine will not provide enough torque and speed to cast in platinum. Our Jewelry Tech Team recommends an upright centrifuge casting machine for casting Platinum. Please let us know if you have any other questions, and thanks for watching!
believe it or not, i successfully cast 90/10 Platinum once on my neycraft and i believe it was only because i had a 10 gauge sprue on the ring that i cast..no thin sprues because itll freeze every time..I also think its worth mentioning that i tried several times before i got it done and my crucible was overheated due to the higher heat of the plat.....platinum casters work 1st time..

Nice. Very clear

How to avoid soot?my casting have always soot in the silver.they appear after i finish cleaning/washing with detergent.thanks and more power
Hello! tell me please, why are you make so many injection channels in the flask?
I am in Vietnam and I really wanna buy this machine !!! How can I buy it ???

ROUND UP
Good evening, I want centrifugal casting machine set in India. How many cost of Indian Rupee.
What Flask tongs are these? They look a lot better quality than the ones that you currently sell.
Thank you for the question. www.riogrande.com/product/neutec-flask-tongs/710270gp

thank you! this helped me a lot!
Great video, pls how much is this particular spin caster? And how do l order. Thank you
@@oppongkwadwokwadwo7636if you need help figuring that out, please stay away from molten metal for your own safety.
This is awesome!
what's better spin casting or vacuum casting?

thanks a lot it help me understanding the procedure in my text book
What's the advantage of this over conventional vacuum casting???
less costly and less maintanance the casting shot is fast and of higher pressures, good for some metals too much for others.
@@anikidwolfy Yeah thanks, I think I'll stick with my vacuum setup. It takes up less space.

Can this one be used for dental castings like chrome Cobalt partial frames?
Hi There, Yes, the Neycraft Spincaster can be used for casting chrome cobalt; however, it will require a high temp crucible. Hope this helps!
Rio Grande thank you
Will this machine cast small parts in brass?
Yes, it will.
