Attendees directly addressed industry pain points, explored paths for industrial innovation, and unlocked new paradigms for clean and sustainable development around key themes such as green and low-carbon transformation and intelligent upgrading. Through innovative drive and cross-industry thinking collisions, the conference fostered consensus, integrated resources, and actively responded to global climate change and environmental governance challenges. This event established a high-end dialogue and resource integration platform, empowering industrial upgrading with wisdom and injecting strong momentum into the high-quality development of the global aluminum industry, jointly drawing a new blueprint for the industry's future.
In addition, SMM meticulously prepared roundtable interview sessions across multiple forums, inviting many renowned industry experts and corporate executives to engage in intense intellectual collisions on various hot topics, including the green transformation of the aluminum industry - the development and outlook of the low-carbon aluminum market, internal and external challenges - exploring new paths for aluminum plate/sheet, strip and foil enterprises in the fog, roundtable interview: discussing new models for integrated die-casting cooperation from a supply chain perspective, China's aluminum industry from a global perspective, analysis of factors influencing aluminum prices in 2025 and market forecasts for the second half of the year, building a global green aluminum ecosystem (ESG aluminum prices, CBAM), and the market business models and overseas investment opportunities of global secondary aluminum.
Speech Topic: Exploration of Integrated Die Casting Technology under Industry-University-Research Collaboration
Guest Speaker: Han Jiantang, Project Director of Shandong Hongcan Material Technology Co., Ltd.
I. Background
1.1 Auto Sales and Export Volumes
Market Trends: The automotive market is experiencing rapid growth; costs are decreasing, leading to cut-throat competition in pricing; Chinese automotive brands are rising quickly, breaking the monopoly of foreign brands.
1.2 Automobile Launch Data
The automotive industry has entered an era of rapid development and updates. The proportion and number of new vehicle powertrain types launched in 2024 are as follows: Battery Electric Vehicles (BEVs): 226 models, accounting for 37%; Internal Combustion Engine Vehicles (ICEVs): 204 models, accounting for 34%; Plug-in Hybrid Electric Vehicles (PHEVs): 110 models, accounting for 18%; Extended-Range Electric Vehicles (EREVs): 39 models, accounting for 6%; Hybrid Electric Vehicles (HEVs): 31 models, accounting for 5%.
1.3 Development Trends and Demands for Passenger Vehicles
Functionalization ⇒ Comfort & Lightweighting ⇒ Electrification & Intelligence & Integration ⇒ Personalization & Customization ⇒ Demand for Shortened Development Cycles.
1.3 Demand for Passenger Vehicle Development Cycles
In the past, the iteration speed of new vehicles in joint-venture automakers was slow. For example, BBA typically conducted mid-cycle refreshes every 4 years and major model changes every 8 years, with corresponding R&D cycles of approximately 54 months.
The new vehicle R&D process is divided into three main stages: concept, design/validation, and production launch, leveraging platformization. The concept stage takes 9.5 months, design/validation takes 14 months, and production launch takes 10.5 months. Adding a 2-month market launch phase, the total duration is 36 months.
Agile R&D philosophy has brought the vehicle development process into a modular and digital era, further shortening the development cycle.

Process Principle Differences
Low-Pressure Casting
Pressure Range: 0.01~0.1 MPa (relatively low pressure).
Principle: Compressed air is used to slowly press molten metal from a sealed holding furnace into the mold through a riser tube. The metal fills the cavity from top to bottom under low pressure and crystallizes and solidifies under pressure.
Characteristics: Smooth filling, good metal liquidity, few porosities and inclusions.
High-Pressure Die Casting (Die Casting)
Pressure Range: 10~200 MPa (extremely high pressure).
Principle: Molten metal is injected at high speed (provided by the injection cylinder) into a steel mold, rapidly filling the cavity and solidifying under high pressure.
Characteristics: Fast filling speed (millisecond level), suitable for complex thin-walled parts, but prone to gas entrapment.
Low-pressure casting and high-pressure die casting are two common metal casting processes, primarily applied to the forming of non-ferrous metals such as aluminum alloys and magnesium alloys. They differ significantly in principles, application scenarios, and product characteristics.
Low-Pressure Casting
Advantages: Good casting density, high mechanical properties, few porosity defects, capable of producing larger parts.
Disadvantages: Long cycle time, high mold cost, unsuitable for ultra-thin-walled parts. High production cost, wall thickness must be >3.5mm, optimally 4mm or more.
High-Pressure Die Casting
Advantages: High production efficiency (multiple parts per minute), suitable for complex thin-walled parts, high surface precision. High dimensional accuracy, small machining allowance.
Disadvantages: Castings are prone to porosity internally, typically not heat-treatable (porosity may expand), extremely high mold cost. Wall thickness can be as thin as >2mm.
Low-pressure casting allows for the design of closed beams with arbitrary diameters.
