Thank you so much! We're thrilled you found the video valuable! You're absolutely right-the cost of the mold can be a significant factor in Lost Foam Casting, especially for complex or high-volume production. But the precision and reduced need for machining often offset that cost. Appreciate your insight!

Exactly! Lost Foam Casting is like traditional lost wax casting, but with a modern twist-using expandable polystyrene (Styrofoam) instead of wax. It’s fascinating how such a simple material can create such intricate and precise parts. Glad you enjoyed the video!

You can get a bunch of deforming if ypu dont vibrate the sand properly . However once you get it figured its fast and easy to make not just parts but tools and machines

I figured the steel pipes are seamless enough; no need to add music to smooth things over. 🎤😂

Thank you so much for subscribing! I hope you enjoy the channel.

Eu aprecio sua perspectiva! Os processos tradicionais podem às vezes parecer um pouco ultrapassados, mas eles frequentemente estabelecem a base para a inovação no futuro.

@AlJazariedu boa tarde, trabalho com isso, toda minha vida, a evolução aí sempre ocorre nos materiais, na raiz é o mesmo processo milenar.

@fernandosoares4187 Boa tarde! Que incrível ouvir de alguém com tanta experiência na área! É verdade, o processo base do fundição permanece como um método milenar, mas as inovações nos materiais e técnicas, como no caso do Lost Foam, realmente fazem toda a diferença na eficiência e na precisão. Obrigado por compartilhar sua perspectiva, é sempre bom aprender com profissionais da prática!

@AlJazariedu estou na esperança de me aposentar ainda nesse ano. Boa tarde, abraços.

@fernandosoares4187 Good afternoon! May this new stage of your life bring you lots of health and achievements! Thank you for sharing your journey with us, and may you make the most of your retirement when it comes. Hugs!

The ceramic dip will produce a thin hard skin when dried, although I would have though a high temparature would be rquired to 'fire' the ceramic to make it stable.

In Lost Foam Casting, the foam model itself acts as the pattern. One of the advantages of this process is that no cores are used as in traditional sand casting. When the foam burns out during the pouring of molten metal, the surrounding compacted, binderless sand and the ceramic coating (slip) work together to maintain the integrity of the mold.

NO, the sand that is packed with vibration holds the mold and cores in place . If the temperatures are right the alu replaces and holds the walls back as the metal flows in . Its crazy but it works . I have been doing it in my shop for about 4 years now making placs and tools

That's a great question! While 3D printing has certainly changed the landscape of manufacturing, lost foam casting still offers unique benefits, particularly in precision and material efficiency. Moreover, although 3D reduces material waste, it is not suitable for patch or mass production as it has a long processing time.

No, you can't get proper grain structure

YES, true but you can machine large parts out of foam bought at home depot then cast way faster than itvwould be to do it with the lost pla meathod . I have been experimenting with this method and it works awsome

Glad I could help!

Thanks for pointing out the grammatical nuance. I’ll be sure to use the correct terminology in the future.

Thank you for sharing your experience. It’s unfortunate to hear about the challenges you faced in the industry, and we truly appreciate your candidness. Die casting is indeed a demanding field, and poor design can make it even more frustrating. Hopefully, advancements in technology and ergonomic practices are making a positive difference for today’s workers. Wishing you the best, and thank you for taking the time to watch and comment! I remember one of my engineering students had the same problem in his factory as the rejection percentage of die-cast products was more than 60%. After investigation, we found that the two main reasons were, the die design (mainly the gating system and venting) and the material composition. After using a newly designed die and controlling the material composition the rejection percentage was reduced to less than 20%.

Glad you think so!

I'm glad you found it helpful! 😊

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!

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
