Lost Foam Casting Address Sign

[@makingcookingfixing]

That sign came out amazing!

[@Wrighmachining]

Thank you

[@coevicman3685]

Impressed with your skill set. I got motivated thanks.

[@Wrighmachining]

Let me know if you have any questions :)

[@slicktires2011]

I'm impressed at the detail (sharp edge). Also, i thought some kind of coating on the foam would be necessary to prevent the sand from collapsing as the foam melts, but that is not the case.

[@Wrighmachining]

I was blown away when I first saw it as well. Pretty cool 😎

Glad you enjoyed it !!!

[@roscoepatternworks3471]

Looks good. With my capacity I'd have to cast one number at a time.

[@Wrighmachining]

lol, blessing and a curse. The large furnace has issue melting brass & Bronze due to the size. just wait I have a 24"x24" I'm doing in a couple weeks. That will be cool

[@eylibroder-kd4if]

Would it work with expanding fome so you could fill up a mold with expanding fome and then cast it

[@Wrighmachining]

That is a really good question. I can't answer it from personal experience. However I have heard of guys not having successes with it. Perhaps I will try it next week and get back to you

[@3dworks533]

It`s amazing!!! I didn't know before that you could cast metal directly into the sand. How did you come up with the idea of using a construction vibrator?

[@Wrighmachining]

Ok, great question. so here is another rabbit hole for you to go down on KZbin . Check out kelly cofields channel. This is one of the first guys that I learned from and have been profecting it on signs . He makes car parts but uses a different coating. Originally he started with plaster like a lot of us have .

[@3dworks533]

@@Wrighmachining thanks

[@MICHAEL-ys3pu]

You will probably get a better finish if you use a finer mesh on the sand

[@Wrighmachining]

Thanks for your input Michael. The plaster give an amazing finish however the poor surface finish you see may be coming from the foam not finished

[@hilltopmachineworks2131]

Looks great! Can you make one double sided?

[@Wrighmachining]

The sky is the limit. Both sided no big deal

I thought about using a DA sander, air powered

[@Wrighmachining]

For the vibrating process. Hummm that's is a good thought. I bet it would work for small pails. Like 10L and under

[@rufustoad1]

I have seen another guy do some very tight tolerance stuff with this process and I can not understand why anyone would do a different process like PLA etc.

[@Wrighmachining]

I can see how you would say that . Kelly cofield makes some amazing stuff. The two are very similar with a few strengths for each but sharing many . i have not tryed lost pla but done lost. wax, pla seems like it has the ability to be printed and will hold its form way better . I have found that lost foam will distort and has spacific direction it has to be placed in . What i love about it is that you can make it with very basic tools and turn it into a metal part quickly.

[@zumbazumba1]

Can you put a link to kellys videos? I cant find anything.

[@Wrighmachining]

Oh yes sorry about that, I just put a link to his channel in the notes. Some really cool casting he does .

[@zumbazumba1]

Engine hoist would solve all of your problems ,you can lift crucible with it(add a steel cable so you can pour in steady) and that heavy sand barrel .And since you wont be lifting heavy stuff cheap import one will do just fine.

[@Wrighmachining]

That's a thought. I would need paved surface however. Unless I cut it and put a piviting hard on it and burryed it in the ground to anchor it. Hummm got me thinking not :)

[@marciomila9264]

Muito bom

[@Wrighmachining]

Thank you

[@PopongW]

Apakah bisa menggunakan PU foam spray yg di jual di pasaran?

[@Wrighmachining]

I have not heard of that working well. I think spray foam is a different type of foam.

[@PopongW]

​@@Wrighmachining iya Busa nya agak sedikit lebih keras dan di dalam nya berpori pori besar

[@MartreexbT19780]

I thought unbonded sand is going to collapse

[@Wrighmachining]

I thought so to .... its sometging to do with the pressure of the molten alu and the packed sand. Pretty cool that one can cast complicated parts with simple stuff

[@vwkenart]

Would u be able to cast something for me?

[@Wrighmachining]

What did yoi have in mind ?

[@amritpatel3794]

Have some friend to help. That would be fun.

[@Wrighmachining]

Totally, it's a pretty cool process. I have done a couple of pours that would have been good to have extra hands. I usually am pouring during the week because of my shift work though and all my buddy's are at work. Check out the massive casting video. Now there where a guy could have used extra hands :)
