At the 3:05 mark in this video about some permanent mold casting company there are these feeders that the operator pours aluminum into. After they solidify he twists them off using built in handles.
Is there a technical name for this? And any resources on this technique?
I’m looking to add some to a die mold I’m having cut. It would make having a horizontal split mold easier to fill cause the feeder can have a funnel shape to it. #industry
