Investment Rating - The report does not explicitly provide an investment rating for the liquid metal industry. Core Insights - Liquid metals possess significant advantages over traditional metal materials, including high strength, hardness, wear resistance, and excellent electrical and thermal conductivity, making them suitable for applications in electronics, healthcare, wearable devices, and flexible robotics. However, the industry faces technological bottlenecks in material and packaging, hindering clear industrial application trends [2][5][19]. Summary by Sections Industry Overview - Liquid metals are defined as metals or metal alloys with melting points below or near room temperature, exhibiting unique properties such as low melting points, high conductivity, and good flowability, applicable in various fields including consumer electronics, aerospace, and biomedical [6][7]. Raw Materials - High-purity gallium is the primary raw material for gallium-based liquid metals, with China leading globally in gallium resource reserves and production, providing a cost advantage and a foundation for technological innovation in the liquid metal industry [3]. Applications - The primary industrial application of liquid metals is in high-end chip cooling, where they serve as thermal interface materials (TIMs) due to their superior thermal conductivity and flowability. Other potential applications, such as hydrogen production, 3D printing, and flexible robotics, are still in the experimental stage and have not yet achieved commercialization [4][27][33]. Industrial Bottlenecks - The main bottlenecks in the industrial application of liquid metals are found in material and packaging dimensions. Material challenges arise from impurities in high-purity gallium, which complicate the material system and hinder predictability in modifications. Packaging issues stem from the complex solid-liquid phase transitions and the strong flowability and surface tension of liquid metals, leading to compatibility, design, and cost challenges [5][57]. Production Processes - The production of liquid metal components typically involves vacuum die casting, which offers advantages such as low cost, high complexity, and minimal waste compared to traditional metal processing methods. The process includes low-temperature melting and die casting to achieve precise shapes and properties [20][26]. Future Prospects - Liquid metals have vast potential in flexible electronics and robotics due to their unique properties, but significant technical challenges remain before widespread commercialization can occur. Continued research and development are necessary to overcome these challenges and enhance the feasibility of liquid metal applications [40][49].

Core Viewpoint - The article discusses the evolution and significance of hinge technology in foldable smartphones, highlighting the different types of hinges, their advantages and disadvantages, and the impact of material innovations on performance and cost [2][5][6]. Industry Perspective - Foldable hinge technology has undergone multiple iterations since the first commercial foldable phone was launched in 2019, leading to various technical routes and design philosophies [2]. - The main types of hinge technology include U-shaped hinges, waterdrop hinges, and other types, each with unique characteristics affecting crease control, thickness, cost, and durability [2]. U-Shaped Hinge - The U-shaped hinge, exemplified by the Samsung Galaxy Fold series, is a simpler and cost-effective design but suffers from significant drawbacks such as visible creases and potential screen damage over time [3]. - This hinge design has been criticized for allowing dust ingress and causing aesthetic issues due to gaps when closed [3]. Waterdrop Hinge - The waterdrop hinge, commonly used by domestic manufacturers like OPPO and Huawei, allows for a larger bending radius, reducing screen creases and providing a seamless closure [4]. - While offering advantages such as shallower creases and improved user experience, the complexity of the waterdrop hinge increases production costs and device thickness [4]. Evolution of Hinge Technology - The evolution of hinge technology reflects the transition of foldable smartphones from being merely functional to providing a better user experience, with advancements in materials and structural design [5]. - The latest innovation is Huawei's "Tiangong Hinge System," which supports both inward and outward folding, marking a new stage in hinge technology development [5]. Material Innovations - The performance of foldable hinges is closely tied to material selection, with advancements from traditional stainless steel to revolutionary liquid metal materials enhancing strength and fatigue resistance [6]. - Metal Injection Molding (MIM) is the mainstream choice for hinge manufacturing, while liquid metal offers superior properties, making it ideal for components requiring repeated folding [6]. Market Dynamics - The global foldable hinge market is projected to exceed $900 million in 2024, with a growth rate of nearly 5% [7]. - The introduction of tri-fold smartphones increases the number of required hinges, suggesting further market expansion [7]. - The market is characterized by high technical barriers, dense patent layouts, and a trend towards consolidation among leading companies [7]. Regional Distribution - Hinge manufacturers are primarily located in China and South Korea, with the U.S. excelling in design but less involved in manufacturing [8]. - Chinese companies are increasingly competitive across the entire supply chain, from materials to design and manufacturing [8]. Cost Structure - Hinges represent a significant incremental cost in foldable smartphones, with individual costs ranging from 800 to 1200 yuan, influenced by material choices and manufacturing complexity [8]. - Reducing hinge costs is crucial for the broader adoption of foldable smartphones, with potential improvements through material substitution and process enhancements [8]. Challenges in the Industry - The industry faces challenges such as reliance on foreign high-end materials and increasing competition, necessitating ongoing R&D investment [9]. - However, advancements in MIM technology and liquid metal by Chinese firms are enhancing the self-sufficiency of the supply chain [9]. Market Forecast - The global foldable hinge module market is expected to reach $1.82 billion by 2031, with a compound annual growth rate (CAGR) of 6.8% [10].
