Молодцы❤ с удовольствием посмотрела 🙏😊
Danke für den interessanten Einblick in die chinesische Produktion 👍
Very well done and understandable
Гарна і головне якісна робота.
Por supuesto muestran bien poco de todo el proceso...!!!
Assistimos com gosto👏🏻👏🏻👏🏻
Thanks🥰
I have been following casting techniques for years ( and I sand cast as a hobby ) but I have never seen this process before, I had to watch a couple of times to actually get it , I assume that the coating on the styrofoam is to improve casting surface finish ? 10:09
Lost foam casting technique similar to lost wax. Yes the coating improves the surface finish, but also prevents flash / leakage and effectively becomes the outer mould. This is molten steel or steel alloy (possibly stainless) so very hot indeed. The styrofoam will flash to vapour / fumes instantly. Very nasty fumes too, avoid those.
@@VenturiLife do they escape through riser n sprue? i mean the fumes? wont they form bubbles inside the structure n weaken it? also wouldnt there be some residue left?
Show!!!
How about showing an American manufacturing process
The metallurgy has improved but the process remains. Mold, melt, pour. Challenging work.
lost wax 주조가 아니라 full mold process 입니다
VN làm đc cái này chưa hay vẫn nhập khẩu
Đóng tàu cần
Intéressant, mais les commentaires débiles sont superflus !
wow Amazing
Thanks
嗯，用的是鑄鐵..不過有加料..
Thật tuyệt vời
Yes🤩🤩🤩
這不是聚苯乙烯，這是聚苯乙烯裡有發泡劑...EPS.台灣這叫保利龍
你的补充很准确😘
Quelqu'un a-t-il plus d'informations sur cette méthode de moulage ??

А что,старый добрый клинкет вышел из моды у моряков? Старьё конечно,но как тонко замечено, они вроде довольны. Льют ребята не сталь ,а чугун.Хрен ты отольёшь так стальные детали! Бывал я в таких литейках. Не то чтобы ад, но недалеко от него!

عمل بدائي جدا
❤❤❤
It sad that China does this, I worked , that in past , in America made Valve company , Henry Vogt , shut down and sold oversea .
America is nothing but a consumer society, unfortunately. Sadly, it will be the end of us. No time in history has a society with no export ever survived.
Corporate greed
،مشاهده غريبه❤❤❤
В части колхоза действительно редкое зрелище... Восторгаются только те кто не видел нормальных цехов ЛГМ. В нашем городе их минимум 3
🤩🤩🤩🥳🥳
الصناعات الصينية لقطع غيار السيارات فاشلة .. فهل هي فاشلة هي كذلك في صناعات الخاصة بالسفن
China quality🥶🥶🥶🥶🥶🥶
ان شاء الله
I think it is not steel but cast iron.
Steel with iron not only pure cast iron
El hierro solo existe como mineral, al añadirle carbono se convierte en acero, por supuesto hay muchas clases y calidades de acero.
Los obreros, no usan zapatos de seguridad......que mal 😠
怎不用木模？？
木模沒法當消失模，保麗龍模沾漿做消失模精度比木模好
🤔
공정을 좀 아는 사람이면 믿고 거를 물건들
감사합니다
열악하다 열악해... 스티로폼 패턴방식은
30년전에 쓰던방식인데... 주변환경이나 안전체계나 보면
한국에서는 공장허가도 안내줌
Pretty useless, doesn't show much. Is making valves that big of a secret.
오랑캐쉑덜 ㅋㅋ
