Thank you ! It’s …
Thank you ! It’s always a good idea to melt more than you are going to need to fill the mold so you don’t end up with an incomplete pour. Aluminum doesn’t lose any properties and it can be remelted over and over. The foam was like foundation insulation foam that was sanded and painted. The paint vaporizes on contact leaving a smooth finish but too much paint will make a mess of the surface… Best of luck with your projects and if you have any questions feel free to ask. -Hank

Hello!
Great job …
Hello!
Great job with the lost foam method… 5/5…
I think you had way too much molten aluminum, didn´t you?
I´ve got a question, what kind of foam was used? I´ve tried with regular foam (like the ones used for party signs) and I got a very rough surface where I can see the little foam balls. Yours looks like it has a good finish right out of the mold….

when doing lost wax …
when doing lost wax (investment casting) you first coat the wax pattern with a type of plaster, then melt the wax out leaving a hollow mold to pour the metal into. Google it for more info.

i was just wondering if wax would react the same way would i be able to place the wax sculpture if i were to carve it then place it in the sand and just pour aluminum over it, its just that with wax i would be able to make my own creations.

That’s amazingly creepy, watching the skull smoking like that!! The skull looks awesome, though! How does lost foam compare to sand casting? I’m just starting out and really know nothing, so it is a little frustrating.

I get my Petrobond oil bonded sand from Budget Casting Supply. They are good people and the prices are very reasonable even for the backyard guy that wants to get into metal casting that wants results. Believe me when I tell you that it’s better to go with the good stuff right from the beginning. It will speed up the learning curve and you will get more excited than discouraged…

I thought so. I did quite a lot of sand casting in high school metals class, but none like this. We removed the pattern piece and poured the molten aluminum into the void

Yes, the foam that …
Yes, the foam that is rammed in the sand vaporizes on contact with the molten aluminum and replaces it with metal. It’s a quick way to do a casting that surface texture isn’t too critical. For higher quality you would do a lost wax casting which is very time consuming but the results are amazing.

Lost foam means the foam skull is left in the sand and is consumed when the hot metal is poured in??
