I am a big fan of anything made in Japan = Precision. Thanks to all those hard workers.

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.

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!

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.

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

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 :(
