I do not know the answers to those questions, as I only made the video and not the actual parts. The company is located in Alabama. You may look them up and ask them directly.'
I only produced the video, I don't work for Grede, so I can only tell you what I saw while I was on site at the plant. The parts come out of the mold with somewhat of a matte-satin finish, with a mild texture to it. For any surface that does not need to mate seamlessly, the surface is usually completely usable once initial manufacturing is complete. However, the metal can be milled to a completely smooth finish if needed for parts that need to line up to high tolerance or contact to other metal parts. In almost every case, significantly less processing and finishing is necessary when compared to standard castings. You can find out more, by contacting the company.

When the foam model is coated, the mixture used is resistant to heat. The sand sticks to the coating when the hot metal is poured and holds its shape. The foam evaporates from the heat of the metal, and when the metal cools, the coating and sand have to be shaken free from the cast part in a huge vibrating container, because the sand and coating hold together so well. It is an amazing process, and if you have the chance to visit a casting facility, I think you will be fascinated.
Good question. First of all, the sand is packed in fairly tightly, through vibration and weight. Secondly, when the metal is poured in, it creates outward pressure which pushes against the sand, helping to hold it in place against the walls of the container. And third, the foam evaporates fairly quickly as it makes contact with the hot metal, but the coating on the mold is more heat resistant and holds its shape long enough for the metal to fill the form, so the sand has nowhere to go.
I work for Grede's in Reedsburg, but I was an electrician... however I was a furnace tender for Richland foundry
I'm glad they are still around.
Grede used to have a foundry in Wichita, KS.
Lindo trabalhador parabéns tem mas video 👏🏼👏🏼👏🏼👏🏼quero trabalhar nesta area

do you have any question about the lost foam
@@zhangjian6133 hello, which one is better between lost foam and lost wax in term of cost production and volume productivity?
I can't find anything on the Pryor Oklahoma plane. Why!!
They didn't ask me to put that in the video

I’m curious to know if this was the brewton Alabama plant. Got an interview coming up and trying to do research?
@@Re_DEEMD No, it was not Brewton. But it was in Alabama, outside of Huntsville ... if I remember correctly.
how does the iron stay in the cavity if there is loose sand around the polly pattern is there a special coatings on the polly pattern?

Very nice news
Good information
I'm glad you liked it.
Thanks that was a good video.
I'm glad you enjoyed it. I'm surprised to see that it is my most watched video.
Thank you. I am surprised it has become so popular.
I refuse to believe this is not an instructional video from 1997.
You're not far off. It was shot in 2005
♥.♥
Slightly similar to the Lost Wax method.
Yes, it is quite similar. It allows for more detail and reduced finishing.
Yes it is
thank you
You are welcome!
You are welcome. I am glad you enjoyed it.
that womans voice is every lady over 40 in florida
What a coincidence! She is over 40 and I understand she went to Florida once!
what is the Standard surface Finish and what we can archive in this method castings
pro tip : watch series at instaflixxer. Been using it for watching a lot of movies recently.
@Santino Zechariah Yup, I have been watching on InstaFlixxer for months myself =)
Local 8511 Grede foundry hates there employees
I don't have anything to do with that. I don't work for Grede. I just make videos.
👏🏼👏🏼👏🏼👏🏼 linda
The unbonded sayunnnd
Dayunnnd sun

Video is interesting, music is of zero value, sucks actually...
I would be happy to consider using some of your music, if you have created something that will work better.
