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.

[@robpark93]

Hey man sorry for late reply. Unfortunately my company doesn’t allow me to share additional information on how we cast products. If was up to me I would love to help sorry again

[@MICHAEL-ys3pu]

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 😅

[@williamdussault9093]

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

[@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🙂

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.

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 👌😎
