Lost wax casting. The whole process

Metal. Wax.

[@robertdavis8787]

Thank you for a very informative video, just getting into lost wax after sand/delft clay and cuttlefish casting with aluminium, brass and silver. It is very helpful to see the process done by professionals!

[@robpark93]

You’re welcome buddy 👍 thanks for watching and that’s awesome it’s a cool trade to learn 👌

Hi Rob i love your videos, i was wondering whats the type or name of the vacuum you are using? is it custom vacuum or? i cant find any information online, would be very helpful if you can give me some tips thank you

[@robpark93]

Hey glad you enjoy the content 🙂 unfortunately my company I work for don’t allow me to give out that kind of information 🥲

[@TTF-95]

Great video, where do you source the large perforated flasks? Can't locate anywhere with flasks bigger than 150mm diameter.

[@lundgrenbronzestudios]

You have an amazing set up there. Very nice work too. I envy that.

[@robpark93]

Thanks mate! Appreciate the comment. Yes very fortunate to have the set up for sure 👌

[@robpark93]

Just checked out your work looks dope as well fella 🔥

[@sierraecho884]

Instead of taping up the holes on the flasks, why don´t you cast a silicone rubber sleeve type of thing. You could then simply put that sleeve over the flask in one go and save time for all the flasks this would add up.

I couldn’t work it this work shop with all the wax all over the place. I worked at a factory that did this work years ago when I first left school and everything was kept very clean.

[@robpark93]

If you did this job you would understand why there’s wax everywhere 😅

I work in a aluminum foundry been there for 20 years when we poor we wear spats on our shoes and we have aprons our ladle holds 25 pounds of metal and the tongs are separate from the ladle I didn't see an autoclave because your burn out has a wax catch pan we autoclave our casting to melt the wax out and we burn them out at 1700 degrees for 4 hours than we clean the shells and load them into a holding oven between 900 and 1300 degrees before we can poor them we also degas the mental and take a test slug before we poor any thing we check for gas holes in the slug if it has gas we don't poor till we get a slug with no gas holes

That really old episode of Mythbusters. I'm sure it was first season. Adam got his eyebrow burned off. I think it was the cellphone caused the gas station explosion story

[@MekazaBitrusty]

The tape to seal the holes in the flasks seems quite a waste of plastic. Why wouldn’t they make a removable cover that can be reused?

[@robpark93]

Would have to withstand immense heat in the oven to be useable again

Excellent. Thanks.

Hello Rob!

[@pparker8133]

Hi Mark, thanks for the great video. Impressive set-up. Clean and well organized. You have the process down to a science and it shows in your cast bronze pieces. Just wondering why you chose classic plaster investment rather than ceramic shell? Is this for an architectural company? Thanks.

[@robpark93]

Hi mark. Thanks for watching and glad you enjoyed the video ! So what we do here is completely different castings to the ceramic shell process and no it’s not for architectural company. We work for beardmore.co.uk

[@foramgoswami6788]

Hey it's an excellent learning.. What is the flask size you use and what's the burnout temperature required to be achieved for a flawless casting.

[@rohitjarkani4029]

Waiting for his reply

[@robpark93]

Hi thanks for your comment. Sorry for late reply. we use 3 different sizes of flask for our castings small/tall/big I’m not sure of the exact measurements but for the burnout temperature we set the oven to run up to 720 degrees and that takes a few hours to reach then will sit at 720 degrees for about 12 hours and then come down to 460 degrees ready for us to pour the metal into the flask. I hope that helps and any more questions don’t hesitate to ask ! Thanks🙂

Great video, one question, vacuum pulls air from plaster and that's how you get that sharp cast? But if you pull air in proces when you put plaster over wax how vacum is made after this ? And can you let us know where to get wax in granules? Thanks.

[@a_potat]

hey! is the slurry you made to coat the wax a ceramic slurry? also another qn: How do you make sure there are no air bubbles when the liquid metal is cooling? also This is such a great video to learn about lost wax casting! I am using it for a manufacturing part in my eng course

[@robpark93]

Hey! Yes and then the wax melts away in the oven which leaves the pattern inside the flask/investment. The air bubbles gets vacuumed out in the mix beforehand and we don’t get air bubbles form the liquid metal that only happens in the mix from my experience. Oh wow that’s awesome I’m happy you was able to get so much value from the video. Good luck with the course 👌😎

@@robpark93 thanks so much that helps a lot 🙂

[@user-vs1rg8tw1n]

What is the duration of gypsum curing and the process of increasing and decreasing the temperature. At what temperature do you melt? What is the temperature of the plaster when it is melted?

[@robpark93]

Hi. Thanks for watching. I don’t know the duration but we melt the plaster at 420 degrees

[@benhail3624]

How much would you charge me to do a lost wax cast of a small trinket if i was to send it to you made out of the wax product of your choice? It would not need to be perfect. In fact some air bubles and imperfections would be what I would prefer.
