ISSUE
Damage to die due to continuous exposure to thermal stress
– Thermal stress due to temperature difference in die and molten metal
– Melt temperature : 1,350°C, Die temperature : 2~300°C
– Temperature differ
– ence of approx. 1,000°CShorter die life span compared to dies for aluminum diecasting
Absence of copper die-cas-ting designsUnstable die filling due to high temperature of molten metal
– Increase in shrinkage defects and porosity
Difficulty in operability due to high working temperatureAbsence of standards in copper die-casting process standardsDifficulty in building specialized equipment for copper die-casting
