Leo Havlicek This is a "hot topping" that when applied produces a chemical reaction that produces a lot of heat. The heat helps to keep the metal molten a bit longer so that it can feed the casting longer and prevent shrinkage porosity.
And if you don't eat, you'll die. In which case, the disposition of your body will probably be completed with the help of parts that were made with investment casting techniques. There is absolutely no way you will ever escape investment casting.
Thank you! Veri nice video for engineering students :) I also have a question for you... I want to make an aluminium part by investment casting then milling a central void and then finish. It is a fuel tank connection for an aircraft. Should I just cast all the part and skip the milling, or should I do it the way I mentioned... Any help will be appreciated :)
@drocketman2000 you don't need steel for casting wax. aluminum or other cheaper metals would do fine. and not very expensive considering it's just one or a few molds.
