A trick I have seen is-make it in play-dough, cast it in plaster. break the plaster and pull out the play-dough. re-assemble the mold, and drill holes for the molten metal. cast. machine out the marks.
Not totally true. High accuracy molds are made using a method i forget the name of right now, but it uses resin to coat a prototype and then that resin shell acts like a cope and drag from sand casting. It is just better quality because of the surface finish it gives.
Is there any possibility of the aluminium catching fire? If it did, what would you guys do- just run away and lt it burn? I only ask because I've built myself a small foundry and of all the things that could go wrong I think that would be the worst
Yes, it's possible to make aluminum burn, but so unlikely in a normal foundry situation as to not be a problem. It will not burn in plain air, but will in pure oxygen if you can get it hot enough.
alluminium should be poured around 720 degrees , better to use a pouring bush too this reduces turbulance,, i worked in a foundry for 24 years and believe me i have seen some bad burns,,wear the correct safety gear
Little casting tip for you: don't pour the metal straight down the sprue, make a depression in the sand next to the sprue, and pour into that. Let it run down the sprue hole from that height, not from the height of the ladle. That way you won't get as much loose sand being incorporated in the casting since the metal flowing into the mold cavity won't be so turbulent.
I work in a steel foundry where stuff REALLY explodes, but that's because steel melts around 2800 degrees F. By comparison aluminum melts around 1200 degrees F. I have been hit by molten steel before and I see it every day, but I've never seen anybody blow their hand off. Aluminum is not quite that dangerous because it generally doesn't spatter. As a fellow hobby metalcaster I can add that yes, this stuff is hot, but being careful, patient, and taking necessary precautions will keep you cool.
Yes and I bet you HAVE to wear protection! Your boss would not allow you to work without wearing PPE and without there being safety precautions in place. Would you do your employed work without it, I somewhat doubt it. I could climb up a tree with a chainsaw and use it without protection in my own time but not while working..............
ur wrong mate...aluminium melts around 660 degrees, only cast iron melts at 1200 degrees. common steels such as mild steel melt at around 1600 and high carbon steel at around 1800 degrees...2800 degrees is way too much mate!u must missunderstood
hi alex....can i know what kind of steel you're using (melting pot) in this video...i just want to make one soon...nice video though...!

so for high precision applications, how to they shape the mould ?
muddwell 2 years ago
Hi.
For more precise castings, you can use die casting or invesment casting. Generally casting is not a high precision manufacturing process.
Alex
alexplace2001 2 years ago
for precision work you cast first and then machine- using a mill, lathe, shaper, or other precision machinery- to bring the piece to it's final form.
