You Won't Believe How Spinning Metal Casting Creates Flawless Components

Had no idea this existed, wow... it explains so much. I did always wonder how long seamless pipes were made.

Amazing!

Thanks

Great video, I actually work in a place that does exactly this and uses all the methods shown. It was interesting to see other methods of pouring the molten steel into the bigger horizontal mould. That furnace tipping about that capless bearing was a bit sketchy though, it could pop out if lifted too high, that would make for quite a mess and explosion.

Thank you so much for the kind words! It's awesome to hear that you work in the field and found the video interesting, especially since you’re familiar with the techniques. I really appreciate your insight about the furnace tipping and the capless bearing. That’s a great point! Safety is definitely a priority in these processes, and it’s always good to be cautious of potential risks like that. Your feedback is valuable, and it’s great to connect with someone who’s hands-on in the industry. Thanks again for watching, and feel free to share more thoughts or suggestions on future videos! 👏

Centrifugal casting has been used for years. It's mostly used in casting small parts.

[@AlJazariedu]

You're absolutely right! Centrifugal casting has been around for a long time and is definitely a go-to method for casting small parts, especially when precision and strength are key. It’s amazing how the process has evolved over the years, and it’s still widely used for everything from small components to larger industrial parts. Thanks for watching and sharing your insight! 😊

The few glitches make me think it's an AI voice, but the pops on plosives sounds like a mic. Either way it's hard to tell whether it's an AI voice.

[@AlJazariedu]

Great observation! The audio process can sometimes have those little quirks, and I’ll be working on fine-tuning it to make everything sound smoother in future videos. Thanks for the feedback, and I appreciate you taking the time to watch and share your thoughts! 😊

[@gblargg]

​@@AlJazariedu I'm going to guess that it is AI. The relaxed pacing and pauses make it pleasant and not sound like AI. There is some slightly odd sound during some S sounds, e.g. 0:44 the S in casting. Some distortions in syllables, e.g. 3:17 "impurities", 4:05 "strong".

Reminds me of how they make things like glass sheets by using gravity to float it on the surface, only here "gravity" pulls in all directions.

[@AlJazariedu]

That’s a great comparison! The way gravity plays a role in both processes is fascinating, though centrifugal force here definitely adds that extra dynamic of pulling in all directions. It’s amazing how these different forces are harnessed to create such precise products, whether glass sheets or metal castings. Thanks for sharing that perspective, and I’m glad the video sparked that connection! 😊

How minimal post-processing are we talking? What's the tolerance on concentricity of the inner diameter relative to the outer one, for example in a horizontal configuration? Don't they necessitate a final machining step, like any other casting method for round parts? Pipes may not need that precision in runout, but since you mentioned gears and cylinder sleeves...

[@AlJazariedu]

@schizophrincenthusiast Thanks for the insightful question! You're right-centrifugal casting can achieve impressive accuracy, but like any casting process, some post-processing is usually required depending on the required accuracy of the final part, especially for parts demanding high precision, like gears or cylinder sleeves. Regarding concentricity between the inner and outer diameters, centrifugal casting excels due to the natural forces involved. The centrifugal force pushes the molten metal outward uniformly, which helps to maintain a consistent wall thickness and achieve good concentricity. In a horizontal centrifugal casting setup, the typical tolerance for concentricity is often within 0.05 mm to 0.2 mm, depending on the size and alloy used. However, for parts like gears or cylinder sleeves where precise concentricity and runout are critical, a final machining step is usually necessary to meet tight specifications. For example, while pipes and other components with looser tolerance requirements might not need further machining, gears and cylinder sleeves typically undergo processes like turning, boring, or honing to ensure the necessary precision in inner and outer diameter alignment. So while centrifugal casting reduces the amount of machining compared to other methods, parts with tight tolerance needs, like gears and sleeves, often require that final step for optimal performance. Hope this clarifies, and thanks for raising the point!

Great video! I encourage you to research centrifugal force. It is fictitious force that only exists based on the inertial reference. Basically the molten metal "feels" a force described as centrifugal force but is really only inertia induced by the rotating cast. It is super confusing but fun to study.

[@AlJazariedu]

Great point! I will investigate it
