COPPER DIE-CASTING SOLUTIONS

銅ダイキャスティングは高い硬度、優れた耐食性、最高の機械特性、優れた耐摩耗性、優れた寸法安定性、鋼部品の強度に匹敵する優れた特性を提供します。

高導電性銅を使用したバスバー、電力ケーブル、家庭用配線、および高圧送電線など、産業に適用されています。

複雑な形状の非標準構成要素の場合、高圧ダイキャスティング方法を使用して銅で鋳造することができます。

ただし、純粋な銅は鋳造が非常に難しく、表面のひび割れ、収縮、および内部の気孔が発生しやすいです。銅ダイキャスティングは非常に高い導電度の鋳造物が必要な場合に主に使用されます。

MOLD LIFEPOROSITYOPERATION 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
