Silver has seen one of the sharpest pullbacks in recent years within just a few weeks. From the high of US$97.30 on March 2, the price fell to US$61.21 by March 23, losing around 37%. For the market, this was an abrupt break from the previous momentum.

The gold price is currently causing nervousness once again. Since the start of the war involving the USA and Israel against Iran, the precious metal has recorded a daily loss of 4% for the second time.

1 Current Status of Integrated NEV Chassis Market / AICE 2025 Global Penetration Rate Accelerates In 2023, the global penetration rate of integrated chassis in NEVs reached 18%, with the Chinese market leading (25%), followed by Europe (12%) and North America (9%) (data source: GGII). In Q1 2024, the sales share of NEV models equipped with integrated chassis in China exceeded 30%, with BYD, Tesla, and NIO accounting for 70% of the market share. It is expected that by 2025, the global penetration rate will reach 35%, with a market size exceeding $80 billion (McKinsey report). Chery's Model Performance in the Market Chery launched the all-aluminum pure electric platform “@LIFE,” which uses lightweight aluminum auto body and integrated chassis design to enhance body rigidity and driving range. This platform has been applied to the Ant series models (such as the large Ant SUV), integrating the battery pack with the chassis structure, lowering the center, and optimizing space utilization. By using integrated die-casting technology to consolidate chassis components, it reduces welding points and the number of parts, improving production efficiency and body consistency, but the application scale still lags behind companies like Tesla. Chery focuses on the cost-performance route, applying integrated chassis technology mainly to mid-end NEV models (such as the Ant series) with a price range of 150,000-200,000 yuan, offering a price advantage compared to high-end models from Tesla and BYD. The all-aluminum body reduces weight by 30%, and with the integration of the battery and chassis (CTP technology), the driving range is increased to over 500km, making it competitive in the same price segment. To this end, at the [Aluminum Die-Casting Industry Development Forum] held on April 16, 2025, during the AICE Aluminum Industry Expo, many industry experts will share their insights on the transformation points and technical challenges of integrated NEV chassis. 2 Guest Introduction / AICE 2025 Rong Xiao, Chief Engineer of Die-Casting Technology at Chery New Energy Vehicle R&D Center, Distinguished Young Expert of the Foundry Branch of the Chinese Society of Mechanical Engineers, and a doctoral student at the School of Materials Science and Engineering, Jilin University. He is dedicated to promoting extreme cost reduction and lean innovation in the casting industry, having led die-casting process development at several Fortune 500 component companies and first-tier vehicle manufacturers. He was responsible for the domestic first 5-core ultra-complex structure project for the 10th generation Accord cylinder head, the domestic first lightweight body die-casting project for GAC Aion LX, the world’s first project featuring an integrated front cabin and rear floor assembly for XPeng G6, the world’s first overall chassis one-piece die-casting project for Chery, and the globally pioneering dual-shot molding technology and "zero inventory" model product island. Transformation Points 1. Structural Integration By integrating the battery, motor, suspension, and other modules through integrated design, it reduces the number of parts and connection points, optimizing space layout. It enhances chassis rigidity and safety while reducing assembly complexity, adapting to the trends of lightweight and intelligent design. 2. Material Lightweighting Using high-strength aluminum alloys and carbon fiber composites, it reduces chassis weight to improve driving range. It promotes material innovation and process adaptation, balancing the need for lightweight and structural strength. 3. Manufacturing Process Innovation Introducing integrated die-casting technology (such as Tesla's large-scale die-casting) to replace traditional stamping and welding processes, shortening the production cycle. It requires overcoming technical bottlenecks such as large mold manufacturing and thermal deformation control. 4. Intelligent Design Embedding wire control systems (such as steer-by-wire/brake-by-wire) and sensors, supporting autonomous driving and chassis dynamic adjustment. Through digital simulation, it optimizes design, achieving synergistic innovation in function and structure. Technical Challenges 1. Process Complexity Requirements for ultra-large die-casting equipment: forming large, complex structures requires high-precision die-casting machines, imposing extremely high demands on equipment stability, mold life, and process parameter control. Defect control: integrated die-casting can easily produce internal defects such as porosity and shrinkage, which need to be addressed through simulation, process optimization (such as vacuum die-casting), and online detection technology. 2. Material and Thermal Management Issues The fluidity and solidification shrinkage characteristics of high-strength aluminum alloys must match the die-casting process to avoid cracking or deformation. Large components are prone to residual stress during cooling, requiring optimized mold cooling system design. 3. Design and Validation Challenges It is necessary to use CAE simulation to predict structural strength, crash safety, and fatigue life in advance, reducing trial-and-error costs. Integrated chassis must meet stringent vehicle safety standards (such as crash tests), with a complex and costly validation process. 4. Repair Cost Controversy Integrated structures are difficult to repair locally after collision damage, potentially increasing repair costs, requiring new solutions from insurance and after-sales systems. 5. Insufficient Supply Chain Support Ultra-large die-casting machines and high-temperature resistant mold materials still rely on imports, and domestic alternatives need to accelerate breakthroughs. Recycling and reusing technology for integrated aluminum-based chassis is not yet mature, requiring the establishment of a circular economy model.
