Hey guys my name is Jason with Mount Baker Foundry and today we're gonna be
melting down and casting some stainless steel. So let's go take a look at what
we're working with and I'll show you some of the molds and how it works. So
here's our scrap stainless, this is all 304 stainless from the scrapyard it's
all nice and clean. I've got about a thousand pounds of it. And I'll take you
over here, this is our induction furnace here, we're loading it up with stainless.
And it's about a 500 pound pot, so we're gonna melt down about 500 pounds at a
time. And then we've got two molds over here and we're gonna pour the stainless
right down there and it'll fill in the mold and create a part. So we're gonna do
these two boxes today and then the remaining stainless we'll just make
ingots out of. Here's the pattern of the part we're making, and so here's the this
is the drag, this is the bottom of the part and there's the coat that's the
top of the part. And so you put those in a box, pack sand around them and the sand
holds the shape, you take the pattern out you put the two box halves together and
that gives you the cavity or your material into.
All right they go on for about an hour now and it's it's so bright you really
can't even look down in there. So we're getting close, the thermometer says about
2450 so we're a couple hundred degrees away from starting to melt. And then this
whole furnace you grab the back end with the crane and we just tip her over and
our into our molds.
Came out good!
Oh that's the back flange you're talking about the,re and then this is the
pour spout. Here's our part after the shakeout, you can see it's still pretty
hot. So we'll get her cleaned up and kind of polished up a little bit and we'll
take a look at the finish we got on it. And then for the the rest of the
stainless we just made ingots out of it and emptied the furnace so now we can
remelt those back down and cast more parts out of them. So we get this one
cleaned up and see what it looks like. Here's our two stainless steel parts that we
shook out. They've cooled down a little bit now. You can see there two kind of
parts I think they're pour spouts for some industrial application. But
we've, you can see that the gate and sprue is still on it so we'll have to cut
that off, but the finish turned out real nice. Nice and smooth. And so we'll get
the the gates and sprues cut off and we'll take take a look at it when
they're all cleaned up. And here's our finished product. This is the stainless
steel U trough that we poured and cast and it turned out pretty nice. So I hope
you guys enjoyed watching our stainless steel pour video at the foundry. And if
you have any questions or would like to get something cast, please give us a call
or send us an email all of which is in the description below.
So thanks for watching and we'll see you in the next one.
