Making cheap lost foam casting slurry

Looks like you've been busy

Good show. Looking forward to seeing those big ones cast. Cheers

👍👍👍

Thank you for showing this!

if you take a scraper and wipe the the bucket wall above the slurry line clean after each use, it will drastically reduce the propensity for the dried stuff to fall into and create chunks the slurry. Best, Kelly

And you can fill this with molten aluminum with no major issues? I was under the impression a slurry had to be some unusual refractory material only special gods can acquire. This is awesome! I know nothing of this, BTW, as I have never attempted it. It was only an impression, so looking forward to watching your second part and learning from this!

Dear
I am held to industrial confidentiality and therefore cannot disclose the chemical compounds to product a lost foam coating.
In any case the coating cost is not the most expensive part of the process. I'll show you a book edited by the American Foundry Society for those who want to learn more and pour good parts --> LOST FOAM CASTING MADE SIMPLE by Fred Sonnenberg and others.

Can’t wait to see more of this. I’m new to casting but lost foam seems to consistently make clean parts. I’m excited to dry this myself.

Just curious if that mixture is ready for the casting process? How long would it take before it gets sturdy?

Op aonde encontro esse isopor aí .qual nome dele

Get a rigid mixing drill and if it shits out you can return it for the warranty.

i do wonder if that mix would work with lost pla casting

Dear Mr. Wright,
I’m genuinely intrigued by your video to utilize dry wall compound as a suspenda slurry alternative, although in my country drywall compound that comes as a paste that’s been shown in you video is not readily available so I’m wondering if it would do just fine to use a powder form drywall compound and mix it with water into the right consistency?

And also thank you for uploading this video I have learned a whole lot more about casting metal. ❤

You could pull a vacuum on the bucket to get the air out like they do on epoxy pours.

Thank you for sharing

Apakah bisa foam langsung di masukan ke cetakan mold?

The shells don't dissolve in water once they're done? ...and the water content don't make them crack when dried or heated? I've thought about trying to use dry wall compound myself, but always discounted it, because I assumed it wouldn't work.

Anyone who has done this, what kind of surface finish/detail are you able to acheive with the watered down joint compound? Currently testing this a few ways going looking for the most immaculate part casting with a lost pla or lost wax casting. Have a few different mixes drying with added flour silica, added waterglass. The joint compound seems to hold up pretty well but i need perfect for a 1 tine cast of a precision mold😂 asking alot i know and am too cheap to buy a ceramic slurry so.. help/experience/tips tricks appreciates

Americans are the people in the world

I thought this video was for lost foam, not plaster....

Consistency of gravy. 👍
