The Lightweight Trend of Electric Vehicles: Technological Innovations in the High-Pressure Die-Casting Aluminum Alloy Industry

With the explosive growth of the global electric vehicles market, lightweight has become a core demand for automakers to enhance range and reduce energy consumption. Aluminum die-casting technology, characterized by "high strength, low density, and recyclability," has emerged as the preferred material for manufacturing automotive components. Data shows that aluminum die-casting parts account for 20-30 kilograms in a modern vehicle, while in key components such as battery housings and motor controller housings of electric vehicles, the proportion of aluminum die-casting parts exceeds 70%.

Technical Advantages: EMP Casting's Solutions

As a company deeply engaged in the high-pressure die-casting field, EMP Casting focuses on the manufacturing of core components for electric vehicles, providing three core values:

Precision Design and Manufacturing Capability: Utilizing high-precision molds and intelligent production lines, we ensure that products such as motor controller housings and battery housings meet stringent requirements for dimensional accuracy (±0.05mm) and surface finish (Ra≤1.6μm), satisfying demanding sealing and heat dissipation needs.

Material Innovation and Process Breakthroughs: We develop high-strength aluminum alloys (such as AlSi10Mg) and composite die-casting processes, enhancing the tensile strength of our products to over 380MPa. Additionally, T6 heat treatment is employed to optimize corrosion resistance and extend the lifespan of components.

Industry Opportunities and Future Outlook

Driven by favorable policies and market demand, the Chinese die-casting industry is accelerating its globalization efforts. EMP Casting is seizing opportunities through the following strategies:

Compliance with International Standards: Our products meet the technical specifications of European and American automakers through IATF 16949 certification, supporting the supply needs of brands like Tesla and Zeekr for their overseas factories.

Collaborative Industry Chain: We collaborate closely with Lizhong Group (upstream aluminum materials) and Lijin Technology (die-casting equipment) to create a closed-loop ecosystem from raw materials to finished products, enhancing cost control and delivery stability.

As the global electric vehicles market continues to expand, EMP Casting actively responds to market demands, committed to providing efficient and reliable die-casting solutions for electric vehicles, thereby contributing to the sustainable development of the industry.
