Coin Production Process 1
1. Melting
Coinage materials are melted in an electric furnace, and ingots are produced by a continuous casting machine.
2. Hot Rolling & Cold Rolling
Ingots are heated in a soaking pit. While hot they are rolled out and made into coil shape. This is followed by rough and finish rolling to complete the rolled plates having the thickness of the coins to be produced.
3. Blanking
Blank discs are punched from the finished plates. These are what we call "Engyo" (blanks).
