- Lost wax casting or investment casting is used heavily in the jewelry making business to create beautiful pieces out of precious metals. With castable resins, there is no longer a need to hand carve wax models. Castable resins give more versatility andimmaculate details that are near impossible by hand.

I have been daydreaming to get to this part of casting. It may be a bit longer but your video now gives a solidified vision. Thanks.
THANKS SO MUCH. YOUR TUTORIAL IS GOOD AND THE METHOD OF PRODUCTION IS INNOVATIVE AND SIMPLE.
SUPER HELPFUL thanks for making this so simple
Good video!
Question-
Is the huge sprue diameter necessary because of the vacuum rather than centrifuge casting? I only use the heavy sprue when stacking multiple models on a "tree" set up....
Thanks! Dave
Do you sell the equipment? Can you give me a list of price for all?
Thanks!!!
Invaluable.. Thank you, you gave me many answers to my questions.. Thank you again :-) Subscribed x
So with the vacuum cast you don't need a hole in the mold? How does the metal get sucked down?
That was the best damn casting video i ever seen 💯
Question about the vacuum pump used. Have you found that the CFM matters when casting. Trying to figure out if a 3CFM vacuum pump will suffice or if I need to go bigger. Thanks
What size flasks and rubber sprue basses are you using...? Also where can i purchase them from!?
Nice video. Although the borax is not needed since the crucible is graphite. If using "whip and torch" then borax is needed. Keep up the awesome work!
doesnt the flask lose the exact twmp it needs for the metals to flow ?
TO ALL READERS, divesting the hot investment release a big amount of silica and quarts particles, make sure you all wearing the right mask and doing it under a good ventilation.
Can you please tell which type of mask to buy or any other precaution equipment

nice video. What tabletop graphite crucible did you use for that ring? thank you
Use Argentium 935 on silver no pickle will be needed ! , I see you use rio grande , they all ways good and have the best stuff !
Hellow l just have one question for you? l was wondering if your metal melting furnace gets hot enough to melt stainless steel? 🤔
I’m confused how the vacuum works for the metal pouring portion. Does the investment plaster have tiny holes in it? The bottom looked solid, so there’s no large holes, how does the vacuum draw in the molten metal when there is solid investment plaster between the vacuum and the metal?
This video is very helpful !!
Hello, can i ask if is necessary the silicone pad or if i can use another material? i cannot find one here in Italy... that pad resist 600 Celsius?
Would you recommend that riogrande vacuum and casting machine? I'm afraid to get a riogrande brand because they're not really known to be manufacturers. I want the dura-bull casting and vacuum but that one is double the price.
Hello,thank you for nice video, please teach me the name of the casting machine and where I can buy .thank you
Can you provide a list of tools/materials used in this video?
Bookmarking for my class- thanks for posting

I want to buy the Rio Grande vacuum/casting table but does it matter what pump I use as long as it is the correct cfm ?
I have a burning question. What kind/size wax sprues are being used at 0:45 ?
Could you please tell us what is the investment (povder material) you are using, is it ceramics or some cind of plaster? where do you get it?
Thank you very much
Is it necessary to get 2 table top furnace could I use 1 for wax and melting metal
After casting what would happen if you waited until it cools before putting in water?
hello there this is Joseph Stevens, I am a big fan of yours I watched all of your videos I really enjoy your jewelry making. I had a question if you don't mind, is vacuum casting better than certificate casting. also what is the best way to that someone can sell their jewelry pieces
What the size of rubber sprue and the cylinder flak ? Thanks
can any one tell me how vacuum tabel works in cast setup? is there a hole(some sort of air vent in investment) or the material is so porous it lets air out? coz i didn't see her put any air vent and thought whole vacuuming investment is to not make it so porous
Hi, I'm from Argentina, using the metal, is it with something that aspires so that it enters the mold? and what is plaster? how white what material is it? Thank you
Nice setup 👍
Hey do you think I could buy a cast off from you? I want to make my own gold pendant but I don’t have the materials to make the cast
which casting powder do you recommend?
hi, may i ask is this normal resin or wax - like resin ?
Very cool!
Can you micro pave set with this method?
Hi! What is the name of the machine in which the wax melts and the mixture hardens? thanks
Thank you for the video!
What kind of resin is used for this? Regular resin or is there a special kind? Help anyone
4:10
How much time kept the flask inside in to the burnout furnas ?
how hours did you set for heating the furnace ?
How to avoid casting shrink? Is there a formula? Please advise?
casting grains with borax? what was the first about?
How many cfc dose your vaccum pump gives?
Hi, what is the white material? common wax?
i have the same kiln as you, did you do any modifications. ie. drill vents or anything for the wax to evaporate?
She didnt use wax, the resin just burned up completely at 1350 degrees.
Is it possible to also cast stainless steel as well?
great video , thanks for sharing. Do you offer 1 on 1 tutorial ?
Thank you very nice of you to show that,
What is the vacuum table doing when you pour the melted metal? ............. why do you need to put the cast over the center hole? there doesnt seem to be a hole or opening at the bottom of the cast? ............ so my question is why are you using the vacuum table when you pour the metal?
How many time need to put or hours in furnace
why not vacuum the pot directly after casting for optimum result?
nice set up you have
I melt a small blob of wax into the rubber base and level it so there is no protrusion from the bottom of the rubber cone. Then I attach a short wax sprue like you did, but thinner than the shank of the ring, yours is too thick, and make the height of the sprue as short as possible. This way when you calculate how much silver or gold is needed you will need much less because the weight of the wax is much less. Also, placing the flask into an oven only ten minutes after setting is a good way to explode the investment. Need at least 2 hours. I don't use a burn out cycle table in my castings. I set the oven for 425 F at 1 hour and check periodically so I can dump the wax tray. After 1 hour I go direct to 1340 degrees for 1 hour and then go down to 950 for a half hour and then take the flask out and into the casting chamber and cast. Never had a single problem with this method over hundreds of castings. Cheers. ;)
Hello. Thank you for the advice. We are using a 3D printed resin, so our casting cycles and investment types typically vary from wax models, but many concepts still hold true. Thinner touchpoints and shorter sprues are ideal, but we hope that the examples in our video make it easy to see and understand for beginners who can further explore these types of refinement.
i used to burnout cycle toooo expensive.i burnout for 1 or 2 hours at 730c or ontill investment is white not grey let it down to about 600c for half hour
What brand of investment did you use?
How much gold alloy do you need? How do you calculate it?
what is the largest flask (X number of castings) you can achieve using that size casting table? is it only good for single items or can you make a few at a time?
You can put many models in a flask. A vacuum table like that can handle flasks up to about 5" diameter and 7" height. You could put dozens of models in the flask if you attach them to the sprue carefully.
Te saludo desde Colombia🇨🇴 un abrazo 🤗 ☑️ 🎥
thank you
The hot metal melts all the wax?
How much would you charge me to do a lost wax cast of a small trinket if i was to send it to you made out of the wax product of your choice? It would not need to be perfect. In fact some air bubles and imperfections would be what I would prefer.
haipls give me thermal timing and setting for the same thanks In advance aboo ibana
Hey where did you get that machine and how much did it cost?
can i have a list of equipment?
I like this kind of casting
Ill add my 2c for everyone asking
Rio grande is the best place to find all these supplies youll need. They even sell a full casting kit that has everything you need and some so you dont have to piece it all togeather. You will need to buy a killn and if you can spring it a automatic melting furnace. The wax is a castable wax, not sure what she is using but Formlab is what i use and they are top notch.
Where is the best place to buy the casting grain?
Thank you! Could you please tell me what model you Rio Grande vacuum table is please!
starting from what temperature to how many bosses, and how many hours it takes
how many grams of silver did that little flask take for one ring ?
does anyone know what white powder is used as a mold
Nice vidio. I want to know what is the plask temperature in this vidio
Thanks for the video
Would it be possible to specify if this process can be done with ANY vacuum table, provided theres a correct pomp attached ofcourse,
Or does it have to be a table built specifically for this process. Does the table itself require power?
Kind regards
The table we're using has a very simple system that's only powered by the vacuum pump, and I imagine that any table put together in a similar way will produce similar results. For safety though, we always recommend going through a vendor with a product rated for this kind of use.
When you replace the silicon mat with the ring how come the ring doesn't burn up when you put the hot flask on the rubber ring when casting? Thanks for the video!
Dennis Goldstein it was a carbon ring, I think so.
Where we can by that casting machines.
Excelente.
Where can I buy the wax rings or better yet where can I buy everything on the video and what are the names or item numbers of each machine?
I want all the equipment and where is best to purchase
Where to buy that rubber base? How does it called
How come u only pour a little bit ? How do you know how much to pour.
why you didn't put all parts in one flask?
what kind of investment mix was that?
how many minutes does this little flash burn
How much time takes to burnout process
Where can i buy this equipament kit??
I'm just learning about this process and I have to say, I like your vacuum a lot better than those centrifuges people use! Those things scare the crap outta me!
But those "centrifuges" work like a damn. Especially when doing larger castings, i.e,: multiple pieces at one time.
@@jayedwin98020 Sorry, but I couldn't understand if you're talking good or bad about centrifuges. I believe you mean that centrifuges are not good, they do not work well. I'm starting, should I invest in a centrifuge or a vacuum?
@@joaoalmeida7620: To Clarify: Casting "centrifuges" work great.
Hi! How can i look for the 3d printer filament? brand/features name? any advice about the printer settings? im looking info because im about to start a school project related to gears and stuff like that, please, help me.
Google is your friend.
Please where can i find vacuum please
Mam how to calculate powder and gold or rubber
I wonder how the vacuum pump can suck the hot metal in to the investment, since there is no connection between upper hole and the bottom of investment(vacuum chamber). How is possible? Is the material of casting make a porous media to convey the air through?
yes bro the plaster media they use allows air to go through its pourus
What's the name of that white powder?
thank you. you just saved me money on a vacuum table
+Miguel Sanchez Congratulations. We wish you luck with your castings.
+FSLASER (3D Printing) thank you
without using a vaccum table
how u get out the bubuls from liquid?
IM TRYING TO START MY JEWERLRY BUSSNIES WILL LOVE YOUR HELP
हेलो सर यह जो वैक्यूम पंप है यह कितनी हॉर्स पावर की है
how exactly does the vacuum work when pouring the metal in the mold? is there a hole at each end of the mold for the vacuum to pull the metal through?
mold mass becomes breathable after calcination
Can you recommend a source for this equipment?
PLEASE can I have a list of equipment, love your footage!
@David Chatterton Thanks, Chief!
Whats the ratio of watet and invesment?
