Die-casting magnesium aluminum alloy mold

Die casting is a process of metal smelting and processing. It is a casting method that fills the cavity of a steel mold with molten alloy liquid at high speed under the action of high pressure, and solidifies the alloy liquid under pressure to form a casting. plastic injection”. The main features of die casting that distinguish it from other casting methods are high pressure and high speed.

Advantages of aluminum alloy die casting

High production efficiency: The machine has high productivity. For example, the domestic JIII3 horizontal cold air die-casting aluminum machine can die-cast aluminum 600-700 times in eight hours on average, and the small hot-chamber die-casting aluminum machine can die-cast aluminum 3000-7000 times per eight hours on average.

Excellent economic effect: due to the precise size of die-casting aluminum parts, the surface is smooth and clean. Generally, it is used directly without mechanical processing, or the processing volume is very small, so it not only improves the metal utilization rate, but also reduces a lot of processing equipment and man-hours. The castings are cheap, and combined die-casting aluminum can be used. , which saves both assembly man-hours and metal.

構造材料としてのアルミニウム合金との競合において、マグネシウム合金は、密度が低く、強度比が高く、電磁シールド特性と鋳造性に優れているという利点があります。これらの結果、軽量、熱放散、電磁シールドが重要な 3C コンポーネント (コンピューター、通信、消費者向け製品) でマグネシウム合金が優先的に使用されます。また、自動車、航空宇宙、アウトドアスポーツなどの分野で非常に幅広い用途があります。

3C の高集積化により、電子部品や熱交換器の動作中に発生する過熱や変形による部品の故障の原因となる過剰な熱を除去することがより急務になっています。優れた放熱性と機械的特性を兼ね備えた材料の需要が急速に高まっています。コンポーネントの性能を最大限に引き出すには、適切な熱伝導率を持つ材料を選択することが非常に重要です。

Mg合金は、Al合金よりも熱容量が小さく放熱効果が高いため、放熱材料として大きな可能性を秘めています。過去数十年にわたって、マイクロ、ナノ、さらには分子スケールでの基本的な熱伝達を明確に理解して、Mg 合金の熱伝導率を向上させることに専念してきたいくつかの努力がありました。

Zhongmei は、一般的に使用されている AZ91D マグネシウム合金と比較して熱伝導率を大幅に改善できる Mg 合金の開発を目指して、世界をリードする専門家である重慶大学の Pan Fusheng 教授と彼のチームと共同で、マグネシウム合金材料研究所を設立しました。

研究所は実験とテストを続け、かなりの成果を上げています
