You're very welcome! I figured steel pipes are seamless enough; no need to add music to smooth things over. 🎤😂

Great observation, and thanks for the kind words! 🙌 The riser doesn't typically require vents because it is designed to act as a reservoir for molten metal, staying open at the top. Any air trapped in the riser can escape through the open end as the mold is filled. Moreover, the riser is not a part of the cast and it will be cut away and re-melted. In contrast, cope cavities need vents because they're enclosed and could trap air pockets, which would affect the casting quality. Hope this helps!

@mechcntr7185 Thank you for pointing that out! You're absolutely right-Homo sapiens emerged around 300,000 years ago, while Homo heidelbergensis, an earlier ancestor, is believed to have been the first to manage fire roughly 400,000 years ago. It's fascinating how mastering fire was such a pivotal step in human evolution! Appreciate your input!

I'm glad you found it helpful! Best of luck on your quiz-you're going to crush it!

Thank you for sharing your experience! Cold drawn seamless (CDS) and cold drawn welded (CDW) processes are indeed excellent alternatives, especially for applications requiring tighter tolerances and better surface finishes. Each process has its own advantages depending on the specific requirements. Feel free to share more about your use case-we’d love to hear!

Less than a minute? That’s a new record for a fast-forward! I promise to work on the pacing for the next video.

You are welcome

Thank you so much for the great feedback! I'm glad you enjoyed the mold-locking mechanism and appreciated the 3D setup. We wanted to ensure all those intricate details were easy to follow, so it’s awesome to hear the rendering made it satisfying to watch. Thanks again for noticing the setup-comments like yours really keep us motivated to keep raising the bar!

شكرا جزيلا

@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!

Wait, there is a lot to know. Just follow me to watch more digestible videos. Awesome! Thank you!

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! 😊

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! 👏

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! 😊

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! 😊

​@@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".

Great point! I will investigate it

Thanks

Rounding off to 16 runs and 1 day sounds perfectly reasonable! It’s always helpful to simplify numbers for easier understanding.

I'm glad you found it interesting! Metal injection molded parts could definitely be a fun topic to explore. Thanks for the suggestion!

That's how they make Teslas, ever heard of the Giga press?

Tell me exactly what do you need?

Great question! You're right to think that high temperatures would make removing the mandrel tricky. The lubricant used in these processes is specially formulated to withstand extreme heat. While standard oils would break down, high-temperature lubricants like graphite-based or molybdenum disulfide (MoS2) are often used, as they can survive the intense conditions. Thanks for asking, and I hope this answers your question!

@AlJazariedu Asked and answered. Thank you. So many sites & videos show a foreshortend cross-section that always made me wonder how long the inside mandrel is and how does it come out. I saw one UA-cam video that briefly mentioned a post process where the tube is rolled again and it is done in such a way to loosen the mandrel stuck inside. But it didn't explain any further.

@@divermike8943 You are welcome. I appreciate your comments.

You welcome. You commented in the same way

@schizophrenicenthusiast Thanks for your comment! You're right-tolerances don't change as a specification. What I meant to convey is that even after machining, the diameter of the pipe remains within the specified tolerance. The machining process slightly alters the diameter, but the final dimension is still within the allowed tolerance range. I appreciate you pointing that out, and I hope this clears up any confusion!

@@AlJazariedu Thank you for the reply!

@@schizophrenicenthusiast You welcome

thanks

Thanks

Thanks a lot for your support

You are welcome.

I wonder if you mean "microstructure" or "micro-cracks" - After forming the tubes, the hardness is measured if it is as required this means that the tube has the required microstructure. - Ultraviolet magnetic particles are used to inspect the entire tube for micro-cracks and the wall thickness. Hope this helps, if you have more questions don't hesitate to get in touch with me.

Micro structure how to check Pls give ur contact details
