Development dynamics of the die casting industry

1. New Breakthroughs in Ultra-Large Die Casting Technology

Tesla Upgrades Giga Press: Utilizing the latest 16,000-ton die casting machine from Italy's IDRA Group, achieving one-piece die casting of the entire Cybertruck underbody. The number of parts has been reduced from 171 to 1, and production time has been shortened from 2 hours to 3 minutes.

Chinese Automakers Follow Suit: NIO's Hefei factory puts a 9,000-ton die casting island into operation, reducing the weight of the ET5 underbody by 30%; XPeng's Wuhan base introduces a 12,000-ton die casting machine from Liujing, with mass production of a new SUV planned for 2024.

2. Material Innovation Drives Lightweight Revolution

Heat Treatment-Free Aluminum Alloy: Litz Group releases its third-generation high-strength and toughness aluminum alloy, with a tensile strength of 380 MPa, and has been selected by BYD and Li Auto.

Expansion of Magnesium Alloy Applications:

Apple's Vision Pro 2nd generation will use a magnesium-lithium alloy die-cast frame, reducing weight to 80g

BMW Motorrad has developed the world's first magnesium alloy wheel die casting, 25% lighter than aluminum wheels.

3. Explosive Growth in the New Energy Sector

Battery Structural Components: CATL's "Kirin 2.0" battery uses a die-cast aluminum tray, increasing energy density by 15%; GAC Aion announced that all its models will switch to integrated die-cast battery packs by 2025.

Charging Piles: Huawei launches a die-cast aluminum shell super charging pile, improving heat dissipation efficiency by 40% and reducing weight by 50%.

4. Increased Emphasis on Green Manufacturing Policies

EU Carbon Tax: Starting in 2024, carbon taxes will be levied on imported die castings. Leading Chinese companies such as Wencan have achieved a recycled aluminum content of over 60%.

Zero-Carbon Factory: Guangdong Hongtu's Zhaoqing factory has received SGS certification, with photovoltaic power generation + closed-loop recycling of waste aluminum, reducing the carbon footprint of a single product by 75%.

5. New Benchmark for Intelligent Production

AI Quality Inspection Popularization: Top Group deployed 500+ industrial cameras + deep learning algorithms, with a defect detection accuracy of 99.98%, reducing labor costs by 80%.

Digital Twin Application: Yizumi and Siemens have jointly built a virtual die-casting workshop, reducing the number of trial molds from an average of 5 to 1.2.

6. Global Production Capacity Layout Adjustment

North American Expansion: Tesla's Mexico factory will be equipped with 20 Giga Presses, aiming for an annual production of 2 million die-cast parts; Volvo invests $500 million to build a die-casting base in South Carolina.

Southeast Asia's Rise: VinFast in Vietnam signs an agreement with Liujing Technology to build four ultra-large die-casting islands, focusing on exporting electric vehicle chassis parts.

7. Emerging Application Areas

Humanoid Robots: All rotating joints of Tesla's Optimus Gen-2 use magnesium alloy die casting, reducing costs by 40%.

Aerospace: The C929 passenger aircraft cabin door frame of COMAC uses high-strength aluminum die castings for the first time, reducing weight by about 15%.

Market Data

Global Scale: The die-casting market is expected to reach $132 billion in 2024 (Precedence Research data)

Growth Area: The growth rate of die-cast parts for new energy vehicles is 34% (2023-2030 CAGR)

Material Substitution: The penetration rate of magnesium alloy in automotive die casting will increase from 8% in 2023 to 18% in 2027
