I. Behind the $75 Billion Market: An In-Depth Analysis of Demand Structure and Growth Logic

The expansion of the global aluminum casting market is not the result of a single driver, but rather the inevitable result of the combined effects of policy guidance, technological upgrades, and industrial transformation. From the demand side, three core sectors form the "iron triangle" of market growth, with particularly strong demand for low-pressure casting technology.

1. New Energy Vehicles: The Core Growth Engine of the Lightweighting Wave

The explosive growth of the new energy vehicle industry is the primary driver of demand for aluminum castings. To achieve breakthroughs in both range and safety performance, lightweighting of entire vehicles has become an industry consensus. Aluminum alloy castings, with a density only one-third that of steel and higher specific strength, have become the preferred material for replacing traditional steel components. Data indicates that global new energy vehicle production will reach 12 million by 2025, with aluminum consumption per vehicle soaring from 50kg in 2015 to 180kg. With new energy vehicle sales in China projected to exceed 15 million, this sector alone will generate approximately 1.2 million tons of new aluminum casting demand, accounting for over 60% of the global market growth.

Low-pressure casting technology demonstrates unique advantages in key components of new energy vehicles, such as battery housings, motor end caps, and chassis structures. Compared to traditional processes, low-pressure casting (LPD) allows for precise control of casting density and dimensional accuracy, reducing scrap rates by over 30%. It perfectly meets the stringent sealing and heat dissipation requirements of new energy vehicles. Data from 2024 shows that the market size for low-pressure castings in the new energy vehicle sector has reached RMB 15.7 billion and continues to grow at an average annual rate of 12.5%.

2. Green Energy Equipment: A Rigid Market in the Low-Carbon Transition
The rapid expansion of green energy industries such as photovoltaics and energy storage has opened up new opportunities in the aluminum casting market. Globally, new photovoltaic capacity is expected to reach 278 million kilowatts in 2024, a year-on-year increase of 28%. Core components such as photovoltaic brackets and inverter housings account for over 80% of the demand for aluminum castings. These components are exposed to outdoor environments for extended periods, requiring extremely high corrosion resistance and structural stability. The vacuum forming process of low-pressure casting effectively reduces internal porosity in castings, extending product lifespans to over 25 years, far exceeding the industry average.
Demand is also strong in the energy storage equipment sector. With global energy storage capacity growing at an average annual rate of over 35%, the demand for stronger and lighter aluminum castings in battery pack casings continues to increase. Energy storage casings produced using low-pressure casting technology can maintain strength while reducing wall thickness by 15%, significantly improving the energy density of energy storage systems.

3. High-end Equipment Manufacturing: Technological Breakthroughs Driven by Precision
High-end manufacturing sectors such as aerospace and semiconductor equipment are becoming the "touchstones" for low-pressure casting technology. In aerospace, aluminum castings must withstand extreme temperatures ranging from -50°C to 200°C. The gradient solidification process of low-pressure casting achieves uniform distribution of mechanical properties in castings and has been successfully applied to high-end products such as drone fuselages and satellite structural components. In the semiconductor equipment sector, South Korean companies such as Samsung Electro-Mechanics and LG Innotek have already adopted low-pressure casting technology for micro-precision components such as foldable screen hinges and camera module supports, driving product upgrades towards thinner walls and greater integration.

II. Restructuring the Global Market Landscape: Regional Opportunities and New Supply Chain Logic

The $75 billion market pie is being redistributed, with different regional markets exhibiting differentiated demand characteristics and supply chain opportunities. This provides clear guidance for the export strategies of Chinese low-pressure casting companies.

1. European and American Markets: High Thresholds of Low-Carbon Certification and Technical Standards

Leveraging their high-end manufacturing bases, the North American and European markets have become core consumer areas for high-value-added aluminum castings, but they also impose stringent market access standards. Both the US IRA policy and the EU CBAM (Carbon Border Adjustment Mechanism) impose clear requirements on the carbon footprint of aluminum products. The EU even plans to include indirect emissions in its regulations by 2030, requiring exporters to establish a comprehensive carbon emissions accounting system, from bauxite mining to finished product delivery.

Technically, the European and American markets have narrowed casting tolerances from the traditional ±0.5mm to ±0.1mm, and generally require IATF 16949 automotive quality certification and AS9100 aerospace quality system certification. For low-pressure casting companies, this presents both a challenge and an opportunity. Companies that meet the above criteria can enjoy a 20%-30% product premium and significantly higher customer loyalty than in the general market.

2. Southeast Asian Market: Capacity Collaboration Opportunities in Manufacturing Relocation
Southeast Asia is gradually emerging as a global manufacturing hub. Countries like Vietnam, Thailand, and Malaysia, leveraging their labor cost advantages, have attracted a large number of automotive and electronics manufacturers to establish factories. Vietnam's aluminum die-casting capacity increased by 18.7% year-on-year in 2023, primarily serving the export-oriented electronics and motorcycle industries. However, local companies generally lack high-end casting technology, and over 80% of precision aluminum castings are imported.

This presents a dual opportunity for Chinese low-pressure casting companies: technology export and capacity collaboration. By establishing assembly bases in Southeast Asia, they can circumvent some trade barriers while leveraging their domestic core technological advantages to provide semi-finished precision castings. This creates a supply chain model of "domestic technology R&D + local delivery in Southeast Asia," effectively reducing logistics costs and delivery cycles.

3. Emerging Markets: Infrastructure-Driven Growth
Emerging markets such as India and Brazil are reaping the dual dividends of infrastructure development and industrialization, becoming potential growth drivers in the aluminum casting market. India, leveraging its "Make in India" strategy, has seen local automakers such as Tata Motors accelerate their electrification efforts, driving an average annual growth of over 15% in demand for lightweight aluminum castings. Brazil, the only country in South America with a complete aluminum supply chain, is experiencing a continued surge in demand for low-pressure castings in agricultural machinery and aviation maintenance, resulting in an annual import gap of 30,000 tons.

These markets share a common demand for "high cost-effectiveness and localized service," requiring suppliers to provide products that meet international standards while also being able to quickly respond to customized needs. Chinese companies can focus on developing a product portfolio that combines standardization and customization, while improving delivery efficiency through the establishment of regional warehousing centers.

III. Breakthroughs for Low-Pressure Casting Companies: Technology, Compliance, and Supply Chain Upgrades

In the increasingly competitive global market, relying solely on scale is no longer enough. Low-pressure casting companies must build core competitiveness across three dimensions: technology research and development, compliance planning, and supply chain management. Only in this $75 billion market can they secure a place.

1. Focusing on Technology Upgrades: Focusing on High-End Process and Material Innovation
Technological iteration is the key to capturing the high-end market. At the process level, the combination of integrated die-casting and low-pressure casting has become a new industry trend. Leading domestic companies have implemented 9,000-ton die-casting islands capable of producing large structural parts exceeding 1.8 meters in length, reducing the complexity of traditional multi-component assembly by 70%. Furthermore, the application of high-vacuum die-casting technology has increased the passing rate of casting airtightness tests from 85% to 99.5%, perfectly meeting the stringent requirements of new energy vehicle battery casings.
Material innovation is also crucial. The development and application of heat-treatment-free aluminum alloy materials can eliminate the need for subsequent heat treatment of castings, reducing production costs by over 15% while maintaining excellent tensile strength of ≥320 MPa. Data from 2024 shows that the penetration rate of low-pressure castings using heat-treatment-free materials in the new energy vehicle sector has reached 38%, and is expected to exceed 60% by 2027.

2. Strengthening the Compliance Foundation: Meeting Global Low-Carbon and Standards Challenges
Compliant operations are the "passport" to entering the international market. In response to the EU's CBAM policy, companies must establish a carbon footprint accounting system in advance and reduce carbon emissions through the use of recycled aluminum. The current proportion of recycled aluminum used has increased from 35% to over 50%. Every ton of recycled aluminum used reduces carbon emissions by 90% and energy consumption by 95%, fully aligning with ESG trends. In terms of certification strategy, in addition to basic ISO 9001 certification, specialized certifications for different market segments are essential: IATF 16949 certification is required to enter the automotive industry, AS9100 certification is required to enter the aviation sector, and ISO 13485 compliance is required to expand into the medical device market. Companies that complete multiple certifications early can shorten market entry by 4-6 months.

3. Optimizing Supply Chain Management: Building a Flexible and Resilient System
The volatility of the global supply chain requires companies to develop stronger risk resilience. On the raw material side, with bauxite dependence exceeding 60%, companies can establish long-term agreements with mining companies in Guinea and Australia to secure a 3-5 year supply of raw materials. At the same time, they can increase the development of recycled aluminum recycling systems to reduce their reliance on primary aluminum.
On the production side, digital transformation has become an inevitable choice. The introduction of an AI-powered quality inspection system has increased inspection efficiency fivefold, achieving an accuracy of 0.001mm. Building a die-casting cloud platform to interconnect equipment has reduced production energy consumption by 12% and shortened order delivery cycles by 20%. These digital upgrades not only improve production efficiency but also provide customers with real-time visualization of production progress, enhancing trust in partnerships.
