Super!😊

je hebt kennelijk geen idee wat er allemaal mis kan gaan

sorry Klijnstra maar dit is vreselijk om te zien

Hoe duur is een elektrisch takeltje? Wat doet die andere gast behalve fotootjes maken? 35 jaar als bronsgieter gewerkt maar dit slaat alles

is it possible to ask for information?

Please! Use a tapered sprue and a decent pouring basin. And buy a copy of John Campbell's Complete Casting Handbook. Oh, and multiple gates off a downward moving stream like this never works... Martin

So much entrained air. I'm pretty certain that you'd need a tapered sprue to keep the sprue full and to prevent it from sucking air. You might also want to consider a ceramic filter to slow the metal down. I'd also say that a single gate into the bottom of the mold would be better and that gate should be perpendicular and above a runner off of the sprue. Thanks for showing what can happen in a system like this. Nothing like a good visual aid like this to see what is actually happening inside the mold.

Wow, that's a lot of jetting, turbulence, and air bubbles.

Moai filmke!

Can you tell me why you dont get that sink hole on the right side and it only happens on the left? I assume since your pouring on the right it would be hotter, should shrink more on that side? Maybe something you are doing to isolate shrink on one side? I am very curious, thank you for your help.

Very interesting!
