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.
   Advantages :
•  Oxygen free copper
•  Absence of inclusion
•  Excellent drawability to very fine wire sizes
•  High conductivity
•  Excellent resistance to hydrogen embrittlement
