Metal Casting Research
The video featured in this post is fairly recent, and will probably be of interest only to those who are actively involved in casting, and those who like to keep up with developments.
While aimed mainly at industrial level casters, there are lessons which amateur casters can apply.
Thanks to GSMEE member John Bernoth for sending me the link.
As a very amateur beginner, the video made me aware of how little I know about the subject.
You can watch the video on the small screen here, or find the YouTube link to watch it full screen. The video quality is pretty ordinary, but the message is, I found, very interesting.
ps. waiting for the 15 phosphor copper to arrive by our very slow post before I do any more casting. Still in level 3 lockdown. I am making a negative pressure pouring apparatus, almost finished, but after watching the above video I wonder if I am on the wrong track. Maybe I should be thinking about bottom filling, spinners, and restricting the flow rate.
