I'm not sure if this method is die casting or forging have a look at the video.
Weird method of casting iron.

Seems more like die casting, since the metal is still molten.
Here is another way to get a thin iron teapot.
I would like to try this method one day.
Timing would be critical.

Nice to have comfortable footwear in the foundry. I have looked at this video before, they cast really thin cast iron tea pots.
"comfortable footwear"............LOL

Fascinating processes there and really impressive methods throughout. Thanks for posting this .

I was thinking that It maybe possible do away with the metal molds and use core sand instead with this method. Using a coating on the sand you may be able use the sand molds 2-3 times.
I have reused a resin-bound sand mold for demonstration purposes, but it was damaged after the first pour with iron.
I just needed something to pour into, so it worked ok for a non-functional demonstration piece.
I would think 3,800 F plastic refractory may work, and it could be coated with something like "Velacote" (tm) ceramic mold coat, which would prevent sticking.
I am not sure how much preheat you would need to use on the mold, but there is the potential of cracking the refractory when the hot iron hit it.
It appears that the molds in the video are refractory, and they don't seem to crack, but it is possible that that replace the mold with each pan that gets cast. I would guess they make multiple pans with each mold before it fails.
