Then, the molten metal lO of the master alloy is injected from the nozzle 3 onto the cooling roll 2 rotating at high speed. At this time, the molten metal lO
is immediately quenched and solidified, and runs away as a continuous thin plate approximately tangentially to the cooling roll 2.

Furthermore, there is a drawback that cracks and chips occur during the punching process when shaping the core.
