製造している方達もガチムチですね

高温に素肌で耐えられるものなのか…😅すごい。

pumping iron is his job.

I have been working in a place where we were doing things from bronze (from small grave plaques to bigger things like fountains or 'statues'). What surprised me the most, is that those guys does not wear any protective clothes to shield themselves from the heat (bronze smelts at 1200 degrees Celsius). The only explanation I can come with is that they are using smaller bowls to pour metal, while we would put a graphite crucible in the furnace to smelt around 120-150 kg of material at the time, and then pour directly from the crucible. While liftin the crucible from furnace, the heat was overwhelming even at 5 meters distance if one didn't use any extra protection (you know - those silvery suits). The other thing that surprised me, is that they are not using any crane/gantry to lift anything, especially if things weight around 70 kg. Sure it's a two man job, but still... Anyway - the "curing gas" is probably CO2, but I just cannot remember what kind of reaction and chemicals were used in the sand. Also, the spray they've used was quite interesting too, because we often used red clay mixed with ethanol to do the coating of the mold, and burn away excessive moisture. PS. To anyone wondering why the heck is there so much dirt on the ground - molten metal beads can travel quite a long distance on even surface, made of concrete. It's a safety thing :)

[@joansparky4439]

Sodium silicate (mixed into the sand) hardens when reacting with CO2. The spray must have been some carbon 'dust' mixed up with binder.. for smoothing out the sandy surface even more than the fine sand was able to. Overall a pretty simple and inefficient foundry IMHO. One wonders how bad the revenue flow must be that they can't afford upgrades/improvements over time to make it safer, easier and more efficient. Ah well, not my business I guess ;-)

[@christopherroberts2500]

It's important to keep in mind protective clothing, in any real capacity, has only been worn for the past 50-80 years or so. We have literally thousands of years of smelting, metalwork, and other metallurgy done with only the most minimal of protective clothing. A modern conceit if you will, if the only metric is burn prevention.

[@MeThorvald]

@@christopherroberts2500 Well - I suppose that heat resistant clothes are really a modern thing, but I think that in the past, smelters used at least leather garb to somewhat protect themselves from potential burns caused by droplets of molten metal. But still, it's hard to imagine that Japanese laws are so liberal in question of personal safety and protection.

このダンベルでいつもトレーニングしてます、ありがとう❤️

Very interesting sharing. Wishing you a happy and energetic new day. Hope the channel grows more and more. ❤💕👍🤝🙏

مساء الخير عليكم جميعا ٠ اندهشت ولم استوعب ما شاهدت في هذا المصنع القديم وأين في اليابان ٠ ألم تقولوا أن اليابان كوكب آخر ما هذا العمل الغير منظم والمنتظم والغير دقيق ارجوا ان تصححوا أعمالكم وتنظفوا المصنع جيدا ٠في البلدان العربية فيها مصانع للصلب احلى وانظف وارتب وأكثر دقة شكرا لكم ٠

That is some serious weight. Very nice quality.

Love the videos but I'm not a huge fan of the intense violin background music recently

[@jaegerfight]

サムネイル見て、エガちゃんねるの動画かと思ってしまった😂😂😂

[@aaronbaird3533]

Well, that was interesting. Just because you've always done it that way doesn't make it right. I'm really curious how they can compete in the marketplace?

[@robertDK3]

looks bigger then an inch but i trust the professionals

[@christopherroberts2500]

The dumbbell is named after Thomas Inch, who lifted a dumbbell of this size a very long time ago. the information is available online, but the handle is much bigger than an inch, and famous for being extraordinarily difficult to lift with one hand.

[@tructran9939]

Very well!

[@HarryInJapan]

Real dumbbells 💪 ❤

[@MinhNguyen-nl1gm]

Những quả tạ inch hết sức nặng nề. Để cho những người lực sĩ hạng nặng tập 🇯🇵👋.

同じダンベルでも大量生産をするなら、もっと安全で効率も良い製造法があるでしょうに…彼らは偉大ですね。この動画がネット上で陽の目を浴びた事が喜ばしいです。

[@Frankagator]

I wonder why they set the spray paint(??) From the aerosol can alight. Solidifying the sands surfsce? Getting rid of residue in the sand?

[@DavidKlemke]

I'm completely out of my depth here, but I think it's a kind of mold release. I can't think of anything else you'd apply at that stage. However later stages show a decent amount of sand still on the final casting so... yeah I'm really not sure. Hope someone smarter than me can give us the answer!

[@joansparky4439]

Probably some carbon 'dust' stuff that smoothens out the surface of the mold more than the finer darker sand is able to produce (the lighter sand was more coarse). Setting it ablaze 'cures' it sort of as they can't wait for it to dry 'naturally' and certainly don't want the aerosols/binders to be set ablaze when the molten metal is pured into the mold.

For my fellow Americans here that's just over 171 lbs in a single dumbbell.

[@kenport8068]

作ってる人もムキムキ！

[@Dee13i]

Why didn't they move the molds closer to the furnace?

[@bryceanderson4864]

Have you tried working next to the furnaces? I'd rather pack the sand away from the heat and have to carry the metal a distance

[@joansparky4439]

more professional and efficient operations have tracks/cars for moving the heavy bits around. This shop doesn't seem to have enough business to be able to invest/improve its processes it seems?!

coveyor belts, proper wheels, why do they make it so hard on themselves for no reason

[@КумысМамбетов-й8ш]

There is a reason - combination of greed and stupidity …

So it takes four people what looks like an entire day to make one dumbbell of 78kg?

[@bryceanderson4864]

I saw a few different molds 14:18

[@joansparky4439]

The furnace probably melted more than that over it's daily burn, the 3 dumbells were just a 'special' on the side I say.. overall the operation still looks way too inefficient and dangerous.

[@DaveLowe28]

Spot the guy who knew the camera crew were in that day!

[@КумысМамбетов-й8ш]

Safety of the workers is on the same low level as in barbaric countries such as India , Pakistan and such … I did not expect that in Japan … now I know 🤮
