Automotive Die Casting Part Market Analysis 2025

The automotive die casting industry refers to a specialized manufacturing sector that produces automotive components through high-pressure die casting processes. Its products cover key vehicle systems, including engine systems, transmission systems, chassis systems, body structural components, and the three-electric systems of new energy vehicles (battery, motor, and electronic control).

This article provides an overview of the proportion of automotive die casting parts across different materials, regions, and structural applications, helping readers better understand the impact of factors such as rising new energy vehicle penetration, lightweighting policies, and export market expansion on the die casting market.

Why Are Die Casting Parts Widely Used in Automobiles?

By material type, the automotive die casting part industry can be divided into:

• Aluminum alloy die castings, accounting for approximately 75%
• Magnesium alloy die castings, around 15%
• Zinc alloy die castings, about 8%
• Other material components

By process type, the industry includes:

• High-pressure die casting, approximately 65%
• Low-pressure die casting, about 20%
• Vacuum die casting, around 10%
• Other processes

In 2025, the die casting industry shows three major trends: accelerated lightweighting, wider adoption of integrated die casting technologies, and upgrades toward intelligent manufacturing. The industry has medium-to-high technical barriers and is both capital-intensive and technology-intensive, influenced by automotive industry cycles, raw material price fluctuations, and environmental regulations.

Distribution of Die Casting Parts in Different Automotive Structures

In terms of application structure:

• Traditional internal combustion vehicle die casting parts (such as engine and transmission housings) have a market size of approximately RMB 272 billion, accounting for 40%
• New energy vehicle three-electric system die casting parts amount to around RMB 204 billion, accounting for 30%
• Body structural die casting parts total approximately RMB 136 billion, accounting for 20%
• Chassis and other components account for about RMB 68 billion, or 10%

From the perspective of vehicle type:

• Passenger vehicles account for approximately 85% of demand (about RMB 578 billion)
• Commercial vehicles account for about 15% (around RMB 102 billion)
• Advantages of Die Casting Parts Across Different Technical Levels

Automotive die casting components are distributed across technical levels as follows:

• High-end products (integrated die casting parts and precision structural components) account for approximately 30%
• Mid-range products account for about 45%
• Basic products account for around 25%

Regional Distribution in the Chinese Market

Within China:

• Jiangsu, Zhejiang, and Shanghai together account for approximately 45% of total national output
• The Pearl River Delta region (Guangdong) accounts for about 25%
• The Bohai Rim region accounts for around 15%
• Other regions account for the remaining 15%

Industry Growth Drivers in 2025

Industry growth in 2025 is mainly driven by:

• Rising new energy vehicle penetration, with die casting content per vehicle increasing by 15-20% compared to traditional vehicles
• The promotion of lightweighting policies
• Expansion of export markets

However, due to cyclical fluctuations in the automotive industry and volatility in raw material prices, the growth rate is expected to slow compared with previous years.

Conclusion

The automotive die casting part industry in 2025 stands at a transformative inflection point. The sector's evolution from traditional component manufacturing toward integrated, high-value structural systems reflects broader automotive industry trends toward electrification and lightweighting.
