| Upcast Process |
| |
| When a water cooled graphite die is immersed in a bath of molten copper to a certain depth, the metallostatic pressure forces the liquid copper into the die cavity where it solidifies. As the solidified segment is drawn upwards by a pinch roll and stepping mechanism, molten metal fills the die cavity resulting in continuously cast rod. |
