Daniel, you have got it, the flask is open ended, we scrape the investment flat (or slightly concave) then once sitting on the table securely the vacuum is applied to the investment.
How accurate would you say the cast is compared to the wax piece? I'm looking to start something up and I need to find the best way of casting a printed piece. The resin would probably have a high wax content, meaning it could melt out, but I am looking into printing quite fine details, like 0.2mm claws, or filigree? Impressive stuff.
Hi Cristopher - the system will reproducer the wax down to the finest detail (of which 0.2mm is reasonably course) so if you can make the wax model we can help you create it in metal. cheers Quin
does the mold have a hole on the bottom of the flask or is the vaccum just being applied to the porosity of the investment through the bottom of the flask?
This video shows the microfoundry system in action. We have also posted a series of videos showing the making of a silver horses head pendant from wax injection to buffing wheel. Further info on our facebook page steedcraft.
Andrew Butts yes he did - its honest to goodness easy fun, read the manual, be a bit careful, and you can be up and melting your own designs (a pair of wedding rings perhaps?) cheers q
I was wondering what would happen if you don't use vacum to pull the molten metal in place? Would it just simply result in a slightly less sharp object or the absence of vacum would ruin the whole process?
Maybe the molten metal wouldn't enter the mold at all! People use pressure or vacuum or mechanical motion. If you don't do anything it's just gravity casting. The molten metal has high surface tension and I don't think wants to go into the mold, and especially into "details" and corners, so people try to force it.
yes the vacuum pulls through the investment which is porous. If you leave enough investment at the bottom of the flask ll goes well - i have "fluffed it" with very little investment at the end of the flask and had the molten charge flow in to the table - it is a right pain to clear out so you do not do it again tee hee
plaster of paris probably works but it is a right battle to remove afterwards - see the quench vid - jewellery silk grade investment powder washes away with ease
Metal Detecting Canada and the Usa yes it is a 2 stage system we burnout the wax in the burnout furnace giving a hot investment ready to recieve the charge then melt the metal in the metal melting furnace and pour it in.
@@sahilsquadron2286 hi thanks if you have a look at some of the other vids we show that once the metal casting bit has become routine the fun is in inventive ways of producing the wax pattern. We designed the system ourselves and offer them for sale. All the best quin
Hi Hugh, yes you can, copper is the upper limit specific heat capacity wise, but all the copper alloys are fine indeed it's fun to make your own brass, bronze recipe. Silver and gold for jewelry work flow very easily. Cheers quin
no the upper safe limit is copper - the reason being the mocrowave is quite cheap and flimsy - the longer the metal is heated for and the hotter it gets the more insulation is needed to protect the oven - higher temperatures become unpractically bulky
How great to see how this actually works. Most interesting. I found you on the Etsy youtube group
amazing casting

Nice!
Subbed!

What type of wax and investment did you use? And how dit you make the ring? Did you make that directly out of wax?
Ok what is the blue cylinder for, is it a safety buffer between the vacuum pump. So if the investment breaks
does the mold have a hole on the bottom of the flask or is the vaccum just being applied to the porosity of the investment through the bottom of the flask?
Daniel Harris I was wondering this too. I suspect it doesn’t have a hole, or else the molten metal would travel down the vacuum hose.
no hole,the porosity in the investment is sufficient

Watching rapt with my fiancee, I blurted out "Holy shit, did he just melt silver in a microwave??"
Andrew Butts yes he did - its honest to goodness easy fun, read the manual, be a bit careful, and you can be up and melting your own designs (a pair of wedding rings perhaps?) cheers q

the precious
what is the name of the mold investment?
Подскажите засчет чего прокаливается опока? Это происходит в микроволновой печи или на нагреватель ной плитке?
Is that a homemade burnout oven
ok I have a lathe. and a vacuum pump. how does the metal not get sucked down the vacuum tube? so the vacuum just pulls through the investment?
yes the vacuum pulls through the investment which is porous. If you leave enough investment at the bottom of the flask ll goes well - i have "fluffed it" with very little investment at the end of the flask and had the molten charge flow in to the table - it is a right pain to clear out so you do not do it again tee hee
its is so simple! I was WAY over thinking the process!
Is Plaster of Paris porous enough to use as investment or do you need legitimate casting investment to do this right?
plaster of paris probably works but it is a right battle to remove afterwards - see the quench vid - jewellery silk grade investment powder washes away with ease
Ya but I am poor... Haha! Ill see if I can find some around here for a good price
question is the flask burn on the microwave well?
Metal Detecting Canada and the Usa yes it is a 2 stage system we burnout the wax in the burnout furnace giving a hot investment ready to recieve the charge then melt the metal in the metal melting furnace and pour it in.
do you microwave the crusiple at wat temperature and what do do can you explain the setup please
Metal Detecting Canada and the Usa yes we use graphite crucibles and melt copper ready to pour at 1200 c
How long does silver take to melt in a microwave i cooked a frozen corndog in one yesterday it caught fire lol
Hi a charge of 25g sterling silver will melt and be reday to pour in approx 9 minutes (times vary slightly due to users microwaves) cheers quin
@@steedcraft what in the heck, are you serious and where did you get the microwave flask/firebrick combo?????. This is amazing :o liked and subbed

Can you melt copper and brass in the microwave ?
Hi Hugh, yes you can, copper is the upper limit specific heat capacity wise, but all the copper alloys are fine indeed it's fun to make your own brass, bronze recipe. Silver and gold for jewelry work flow very easily. Cheers quin
Can you melt platinum with the microwave Furnece?
no the upper safe limit is copper - the reason being the mocrowave is quite cheap and flimsy - the longer the metal is heated for and the hotter it gets the more insulation is needed to protect the oven - higher temperatures become unpractically bulky
thanks
Металл явно перегрет
