2025 Lighting Die-Casting Components: Low-Carbon Transformation and Precision Innovation Fuel Industry Growth

The global lighting die-casting components industry is ushering in a period of high-quality development in 2025, driven by the deepening of the "dual carbon" goals, the rapid popularization of smart lighting, and the upgrading of terminal demand for precision and durability. As core structural parts of modern lighting products, die-casting components are breaking through traditional application boundaries, playing a key role in heat dissipation, sealing, and structural support of LED lamps, smart home lighting, and outdoor landscape lighting. According to industry data, the global market size of lighting die-casting components is expected to exceed $45 billion in 2025, with a compound annual growth rate (CAGR) of 8.1%, and the Asia-Pacific region accounts for over 52% of the total market share<superscript:2.

Policy-driven low-carbon transformation has become a core trend reshaping the industry. With the implementation of strict environmental regulations such as the EU’s ErP 3.0 and China’s "Industrial Carbon Peaking Implementation Plan", die-casting enterprises are accelerating the upgrading of green production processes. The application ratio of recycled aluminum in lightingdie-casting has increased from 28% in 2020 to 45% in 2023, and it is expected to reach 48% in 2025, reducing carbon emissions per unit product by about 15% <superscript:1. Meanwhile, energy-saving technologies such as aluminum liquid direct supply and electric induction melting furnaces are widely adopted, with the aluminum liquid direct supply ratio rising to 38%, reducing energy consumption in the remelting process by 15%-20% <superscript:1. Leading enterprises in Guangdong and Zhejiang have built green manufacturing demonstration projects, integrating die casting, waste recycling, and VOCs treatment into a closed-loop system, achieving a 98.6% product qualification rate <superscript:1.

Precision technology iteration is optimizing the performance and application scope of lighting die-casting components. The demand for high-precision, thin-walled parts in smart lighting has promoted the popularization of vacuum die casting technology, whose penetration rate has increased from 18% in 2019 to 31% in 2023, reducing the porosity of castings to below 0.5% <superscript:2. Enterprises are focusing on developing components with wall thickness less than 1.2mm, and through the application of MES systems and three-coordinate measuring instruments, the dimensional tolerance is strictly controlled within ±0.15mm, meeting the assembly requirements of miniaturized smart lamps<superscript:1. Guangdong Hongtu Technology, a leading domestic enterprise, has independently developed ADC12 die-casting alloy, whose thermal conductivity and corrosion resistance have reached international advanced levels, and it has become a core supplier for Philips and Opple Lighting <superscript:2.

Material innovation is opening up new growth space for the industry. Aluminum alloy remains the mainstream material for lighting die-casting, accounting for 76% of the market share, while magnesium alloy applications have broken through 12%, enabling an average weight reduction of 15%-20% for lighting products <superscript:1. Environmental protection zinc alloys (low-lead and cadmium-free formulas) are gaining popularity in small and medium-sized lamps, with their market share expected to expand from 30% to 50% by 2025<superscript:1. In addition, composite materials such as aluminum-magnesium alloy combined with carbon fiber are entering mass production testing, which can improve product strength while reducing energy consumption, and are expected to be widely used in high-end commercial lighting <superscript:1.

Market demand structure is showing a differentiated growth pattern. The booming outdoor smart lighting and automotive ambient lighting have become new growth drivers. The market size of automotive ambient lighting die-casting components is expected to reach $1.7 billion in 2024, with an annual growth rate of 19% <superscript:1. The demand for special-shaped die-casting components in landscape lighting is surging, with a customization rate as high as 82%, driving enterprises to invest in flexible production lines, reducing the average mold change time from 8 hours to 2.5 hours <superscript:1. In the European and American markets, the upgrading of energy efficiency standards has promoted the replacement of traditional lamps, and the demand for die-casting components with IP67 protection level and T6 heat treatment process is growing rapidly, accounting for 70% of the high-end market <superscript:2.

The competitive landscape is accelerating towards integration and differentiation. Leading enterprises are strengthening vertical integration, covering the entire industrial chain from aluminum ingot smelting to surface treatment, reducing production costs by an average of 14% <superscript:1. Small and medium-sized enterprises are focusing on niche markets such as micro die-casting components (weight <50g) for mini lamps, relying on customized services to gain a foothold <superscript:1. With the acceleration of digital transformation, the penetration rate of intelligent manufacturing in the die-casting industry is expected to reach 55% in 2025, and remote operation and maintenance systems based on the Internet of Things will reduce equipment downtime by 40% <superscript:1.

Looking ahead, the lighting die-casting industry will focus on balancing low-carbon development, precision improvement, and cost control. With the deep integration of smart lighting and green building trends, die casting technology will continue to break through, and components will develop in the direction of integration, miniaturization, and high efficiency. Enterprises that grasp the opportunities of material innovation and digital transformation will gain a competitive advantage in the global market, driving the industry towards a more sustainable and high-end future.
