Oh, I see... BTW, where is this "Japanese precision" in this process? ;-) As far as I can tell it's just a regular (and tad derelict, if you ask me) recycling plant that re-melts BRASS (NOT "bronze" - regular bronze, i.e. copper-tin alloy is much more expensive and is not used for common everyday objects, more on it latter - and then there are aluminium and silicon bronzes but these are different kind of fish altogether), so this plant here just melts scrap brass and casts brass ingots to be used for whatever castings "further down the line" (like in that another works shown here, that casts impellers for centrifugal pumps), and that's it. BTW, it's a huge waste of energy to melt brass and cast ingots first, let them cool and solidify, then pack them on pallets, transport few yards to another "factory on site" to re-melt them again - they could just transport molten brass form one place to the other one - this is done with steel and aluminium, so it can be done with brass too. But I digress here, and anyway nothing of "Japanese precision" here, and frankly this place reminds me more of these "satanic mills" of William Blake (featured in "Chariots of Fire") - or modern day Pakistani "factories" - than of anything "Japanese precision", but then beauty is in the eye of beholder. Yes, that "impellers foundry" is certainly neater and cleaner, but still "a regular foundry". The molten metal is cast, left to cool down and solidify, the sand mould is crushed, the cast is cleaned and (if needed, as it is in this case) worked on a lathe in order to produce desired machine part - and that's it. Nothing to crow about. Also why I'm confident it's brass? Firstly, look at all that scrap they put into the furnace (4:01) - these are remnants of common everyday objects, like plumbing fittings and old water valves - and these are made from brass (or steel, but they process only brass scrap here), NOT bronze. (Tin bronze is used for casting bells, when admixed with phosphorus it's used for so called "self lubricating" plain bearings.) Secondly, brass is an alloy of copper and ZINC, and the latter one is a rather volatile metal, and its vapours easily oxidize in air producing characteristic white-bluish flame and white fumes of zinc oxide - see at 6:08. Anyone who even once brazed something used regular brass (or cast anything out of molten brass) will recognise it in an instant. In fact the air inside the building is chock full of zinc oxide particles suspended in air - that's this bluish haze you can see at 4:52 and other moments as well. And frankly, the description of what's happening there is rather rife with errors - at 2:53 this worker DOES NOT "mix the metals" (that would be beyond physical strength of any human) but either spreads freshly loaded (i.e. not melted yet) scrap, or he's skimming the surface in order to move to the side all that oxides and junk (so the fresh scrap can submerge into molten metal) - or both. (You can observe the "regular skimming", that is the standard procedure in this whole process, at 6:33; at 6:42 he's agitating the molten brass to help any oxides and junk still inside the molten metal to float to the surface - but that's not done "to mix metals".) Also, specific gravity of zinc is 7 g/cm3, one of copper is nearly 9 g/ cm3, so not that much - AND at any rate they've loaded ALREADY MIXED metal into the pot, right? They did not load zinc and copper there, as separate metals - they loaded BRASS scrap, so what "mixing of different metals"? Makes no sense, right 4:10 - _borax remove(s) oxides_ - well, sorta kinda, but not really. It combines with oxides, creating a kind of a slag with low melting point, which floats to the surface of the molten brass AND prevents the metal beneath from further (and undesired) oxidation. 13:09 - WEIGHING, not "calibration". And then at 23:25 there's completely different process (aluminium alloy casting) filmed in another factory, AND AFAIR this video here is a knocked-up / cobbled combination of previously released SEPARATE videos - as it is perfectly indicated by this ill-fitting "Thank you for watching until the end!" caption (CC) about one-third into this whole thing (which is almost a full hour long). So, I'm outta here. Cheers.
Good video. It's great to see people proud of their hard work. And they were very proud. I'll never forget that man standing with a bronze ingot. It was like he earned a prize, which he fully deserves. But it's also a very hard work - especially the first one. It was surprising how much manual work goes into these products. One would think that in Japan in 21st century all physical work is done by robots. The fact that there were so few young man doing this jobs was also very surprising. It was almost like these older people had entire industry on their shoulders. PS I loved the videos, but would you consider putting more text like int the second one about iron works? The whole proccess was explained very nicely. And translating what the workers/owners say would be very nice.
Some very dangerous industrial processes going on in the foundry videos. I am amazed at the to western eyes almost nil personal protection in view, notwithstanding the visors and gloves. No leg protection in evidence at all. No leather aprons which would have been worn here in the UK even in the 1920's let alone the 2020's in any foundry. The Bronze casting in the last video before the polishing one. The guy doing the preparation of the furnace and eventually pouring into the moulds was wearing no protection shot of a white sweatband round his head! And his compatriot on the other side was wearing long shorts and had bear shins while casting was being done 18" away from him. Our Health and Safety guys would have a fit! I loved the polishing video no real H&S concerns there for me I loved watching the machinery working and the stainless steel came out pretty good! All in all I take my hat off to those workers, they work bloody hard and in difficult working conditions. I'd certainly be wearing a lot more PPE than that lot!
I have the highest respect for each and every worker in the foundry. Their exacting work and dedication bring them much honor and glory to the company. I wish them many more years of good health and continued success.
My respect and admiration, to this workers. This is wy your prodoct are very reliable around the word.Thanks for your lesson. We have a long way to stay like you,Thanks, from Brazil.
I love to see Japanese craftsmen at work. One of the most important lessons as a craftsman: "Whatever the task, always do it with ridiculous precision:. Only this way you get better at it and remember "you can cut a piece of wood much quicker straight, than crooked". My master told me, when I was an apprentice at 14. This is very much Japanese craftsman philosophy
One thing I noticed with the Japanese work place is that everything is clean and organized. Even the smaller manufacturing places are the same. Other countries - especially 3rd world - the working conditions are horrible.
Safety shoes, safety helmet, masks, protection glasses. wow, i cant believe, that someone works that way. normally they wearing sandals and nothing more ^^ good people - they do it the right way
Very nice work you should call building and equipment and get them to fix those fans. It’s probably hard to breathe that stale, smoky air. workin hard like that been there done that🫵🏻👍🏻
how can they see what's going on?!?! mad bright even through a camera at 38:00 amazing, never seen a blurry cast before lol thank you for doing the work you are doing, it's so dangerous, please take care of yourselves and your workmates omg im so drunk, but i really mean it
wow congratulation lads I done all that sort of work in the foundry mine was malt & metal. and worked in a brass factory. And i burns with burst moulds well done. sad to say you cannot get the men or woman to do that kind of work anymore at least not in Britain we are the last of the good workers. best of luck to you all.
I worked in a foundry grinding iron parts after shake out. The first two weeks each morning my fingers were curled from holding that heavy grinder all day. after two weeks work they were ok but have a hook finger that is permanent. Alpha male men do this kind of job.
9:19 you know looking at all that red hot metal cooling down i cant help but think of all that wonderful thermal energy thats just being lost to the atmosphere ... you would think by now there would be some sort of waste heat capture set up where i dont know they dump the molten bronze into a tank of water so that it makes nice little drops of similar weight and then it uses the water that heated by that to power a steam engine or maybe something involving a heat pump .... just seems such a waste to see those thousands of kilojoules just dissipating into the air :(
Worked maintenance in a brass fou dry making fixtures. Wasn't that bad vs this vid. Smoke and them boys wering a disposable 😷 masks. Workers monthly lead testing & backpack powered full face zhield frezh air masks w carbon filtration. 😊 place shut down last year, day i was starting HR called & postpone it when one of tbe workers was killed there. 😢 Good pay buy j was downsized 3 yrs later...😮 The old guy in the 40 min marks making forms & later pouring... 😮 looks to be in 70s+ yrs old. Or seeing the environmental impact and he's only 45?
こういう仕事が社会を支えている。
ソーシャルワーカーへの関心も高いですが、こういう職人がいて国土が成り立っていることも忘れないよういにしていきたいです。
素晴らしく、とても美しい作品ですが、一見、大変で危険な仕事ですが、これらの熟練労働者への敬意の表れです
You should be very proud of the beautiful product that your hard work produces. Great job!
I am a big fan of anything made in Japan = Precision. Thanks to all those hard workers.
روعه ماشاء الله ❤

Number of days since last accident: 1 Number of consecutive days between accidents: 1
I wish Japanese markets were better......i would love to be able to buy Japanese products again like I used to be able to do in the 70's
Some of the best craftsmen in the world! And they also produce some of the highest quality you can find!!
Amazing work gentlemen! Thank you for sharing. 🙇♂️
I have the highest respect for each and every worker in the foundry. Their exacting work and dedication bring them much honor and glory to the company. I wish them many more years of good health and continued success.
Profesionales para trabajar, exito en el desarrollo...😮...gracias...........
Great work, men and women. I know that you work hard, but your finished product is amazing. Thank you ❤🎉🎉
My respect and admiration, to this workers. This is wy your prodoct are very reliable around the word.Thanks for your lesson. We have a long way to stay like you,Thanks, from Brazil.
I love watching these kind of videos while others lose their attention span on TikTok. :)
Very good job congratulations ,god bless you, thanks for doing it us ,from Brasil
金属に命を与えるような男らしい仕事だ、憧れる。
Всё также как и в наших литейных цехах, и задница мокрая! Литейщикам японцам привет!

Cómo siempre que bien trabajan los ciudadanos japoneses saludos desde argentina,👍
Bravo pour ces artisans habiles et meticuleux
One thing I noticed with the Japanese work place is that everything is clean and organized.
Even the smaller manufacturing places are the same.
Other countries - especially 3rd world - the working conditions are horrible.
Love your work! A lot of this is new to me, I used to work in high pressure die casting.
good job. I love to see japanese craftsmen.
very cool operation was very interesting to watch
Safety shoes, safety helmet, masks, protection glasses. wow, i cant believe, that someone works that way. normally they wearing sandals and nothing more ^^
good people - they do it the right way
Furnace
melting
core making

i love this job ❤🎉🎉🎉
From 🇲🇾
Much respect to the workers in these foundries!! 🙏🙏🙏
bonne sante a tous ces travailleurs c est exeptinnel et fascinant ses metiers merci bien
Why don't we ever see young men working in these factories? Do they think the work is beneth them?
A lot of this young generation is lazy. They would rather sit behind a computer screen and in Air conditioning than do manual labor.😢
Open all the windows! Get some fresh air! - just to watch this video!
Very nice work you should call building and equipment and get them to fix those fans. It’s probably hard to breathe that stale, smoky air. workin hard like that been there done that🫵🏻👍🏻
Well done, brilliant work you must be very proud!
好佩服头发己花白的員エ，工匠。赞！👍
how can they see what's going on?!?! mad bright even through a camera
at 38:00 amazing, never seen a blurry cast before lol
thank you for doing the work you are doing, it's so dangerous, please take care of yourselves and your workmates
omg im so drunk, but i really mean it
great workers great work and great factory ❤❤
Excellent work
11:57 Best part of the whole video.
Multumim pentru traducere.
amazing works, i dream to have one of those company.👍
wow congratulation lads I done all that sort of work in the foundry mine was malt & metal. and worked in a brass factory.

ΣΥΓΧΑΡΤΗΡΙΑ !! ΣΑΣ ΒΛΕΠΩ ΑΠΟ ΑΘΗΝΑ . ΕΛΛΑΔΑ. ΠΟΛΥ ΚΑΛΗ ΔΟΥΛΕΙΑ!!
Вы молодцы! Это очень опасная работа
muito bom. a. sabedoria. de. vocês
para. bem
Nice job 🙌
Very good working prosses
They ever hear of "clean-up" at the end of the day?
BEST BEST BEST!! I love japan!
Не понимаю , что страшного в этом процессе ? Обычная литейка , как везде ...
In welk land bedoel je ?
They need fire proof suits. Thats way to close to
What do they do with the slag ?
It's mostly mineral residue that did not burn or ashes so it can be disposed of as landfill.
Die voeren ze sla 😂😂😂
I worked in a foundry grinding iron parts after shake out. The first two weeks each morning my fingers were curled from holding that heavy grinder all day. after two weeks work they were ok but have a hook finger that is permanent. Alpha male men do this kind of job.
Do these guys get paid fair wages? I think I'd enjoy this work, except in my country, this work doesnt pay enough to support a family.
can you reclaim the casting sand
Working here looks like a good way to shorten your life
If you see this, you're a neat person
That’s burning with zinc fumes!
Well
Japanese love blured video 🤣🤣
Erm Guys what happened to the health and safety inspector? Hmm he had an accident boss. Ok carry on
25:00 "main cutting die" ?(
Great job, not like Pakistan, the Japanese have concrete floors.
And shoes vs flip flops. And no 8 to10 year old kids working.
После такой работы в ад не примут, только рай.
if you are scared on manual labor, then yes, this is scary.
Гарна робота. Молодці.
If they show something blurry, don't show it. It takes away all the seriousness.
...and blur is non destructive - better put a black bar over it
Енбектін енбегі екен.👍

Good pay buy j was downsized 3 yrs later...😮
The old guy in the 40 min marks making forms & later pouring... 😮 looks to be in 70s+ yrs old. Or seeing the environmental impact and he's only 45?
Було вражаюче цікаво, моя пошана для працівників ливарної промисловості. Вітання з України.
Bravi!!
Почему так много ручного туда.Завод старый и вообще не обновлялся .
Это экономическое чудо японии. )
А где новьіе японские технологии так лили в 18 веке
Scariest video I've ever seen.
👍👍👍
