| MOLD LIFE | POROSITY | OPERATION CONDITION | |
|---|---|---|---|
| TECHNICAL 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 |
