The arrival of Apple's inaugural foldable iPhone is drawing near.

From an anticipated stocking volume of 7 to 8 million units, to a sudden surge to 10 million; from confirmation of mass production commencing in late July to supply chain firms gradually revealing small-batch shipments—this long-anticipated product revolution is transforming from mere speculation into reality.

Several A-share listed companies have confirmed their deep involvement in the manufacturing and supply of core components, spanning from ultra-thin glass to hinge systems, and from flexible circuit boards to complete device assembly. A supply chain centered around the foldable iPhone is swiftly taking shape. However, initial production capacity will be a mere 1/20th of that of regular flagship models, making it almost inevitable that supply will fall short of demand. Who will claim the largest share of this lucrative market, and who might fade away as just a fleeting trend?

01. The Dawn of a Multi-Billion-Dollar Market: A Substantial Boost in Foldable iPhone Stocking Targets

Apple's confidence in its first foldable device is already evident in the order numbers recorded in the supply chain's ledger.

The latest reports indicate that Apple has significantly raised its stocking target for the foldable iPhone in 2026, from the initial 7 to 8 million units to approximately 10 million units. This is not an isolated increase in orders—Apple has simultaneously secured component production capacity for about 80 million new iPhone units, with a full-year iPhone production target of around 220 million units for 2026. Among these, orders for the iPhone 18 Pro and iPhone 18 Pro Max are expected to reach around 70 million units. The first foldable model is anticipated to make its official debut at the September autumn event, sharing the spotlight with the iPhone 18 series.

This is no small-scale trial run. The stocking volume of 10 million units signifies Apple's ambition to challenge for the top spot in the global foldable smartphone market in its inaugural year. Data from market research firms suggests that the foldable panels used in the iPhone Fold are expected to account for about 29% of global foldable smartphone display orders in 2026, second only to long-time market leader Samsung. In a consumer survey, over 60% of respondents expressed interest in purchasing a foldable iPhone. Considering Apple's massive user base and brand appeal, actual demand may well surpass expectations.

However, manufacturing challenges loom large. Due to the innovative foldable design and stringent quality control requirements, production capacity for the foldable iPhone will be severely limited in its initial stages. Industry analysts point out that assembly shipments in the third quarter of 2026 are expected to be less than 1 million units, only 1/20th of regular flagship models. This scenario echoes the launch of the iPhone X in 2017—due to supply shortages, premiums on unofficial channels once soared to over 50% of the official price. The history of the foldable iPhone seems to be repeating itself, but this time, the supply-demand gap may be even more pronounced.

02. Ultra-Thin Glass and Hinges: Domestic Prowess in Two Key Areas

The biggest technical hurdles for foldable smartphones lie in the screen cover and hinge system. In both domains, Chinese companies hold pivotal positions.

In the realm of ultra-thin flexible glass, Lens Technology emerges as Apple's core UTG supplier for the foldable iPhone, accounting for about 70% of the total supply. Its UTG mass production yield rate has surpassed 95%, well above the industry average. More crucially, the requirements for glass covers in foldable phones are significantly higher than those in traditional bar-style phones—the per-unit value is about 3 to 5 times that of traditional glass covers, implying that Lens Technology's revenue potential from this single model far exceeds that from any previous iPhone generation. This logic has already been validated in the capital markets, with the stock price surging more than 70% year-to-date.

The hinge system represents the component with the largest cost increase in foldable smartphones. Hinges must endure over 100,000 folding cycles, imposing extremely high demands on material strength, precision, and durability. LUXSHARE-ICT is widely regarded as Apple's core hinge supplier for the foldable iPhone, with its share in the hinge supply chain exceeding 25% and having implemented a full titanium alloy material process. LY Technology offers the most comprehensive product matrix, supplying Apple with support components and hinge modules crafted from stainless steel, titanium alloy, and carbon fiber, with its ultra-thin titanium alloy foldable support components already in mass production. Yian Technology stands as the exclusive supplier of liquid metal main shaft structural components for foldable hinges, with its liquid metal being twice as strong as ordinary stainless steel and remaining deformation-free after 100,000 bends, supplying 90% of China's foldable liquid metal market. JY Technology boasts significant technical advantages in MIM precision components, with process precision reaching 0.005 millimeters and supporting over 500,000 folding cycles, already achieving large-scale application in Android foldable smartphones. These four companies form a complete domestic supply chain matrix for hinge components, ranging from liquid metal to precision parts, and are the most closely watched targets in the current foldable smartphone market.

03. Assembly Contract Manufacturing and Core Components: Identifying the Next Growth Catalysts

In terms of complete device assembly, Foxconn Industrial Internet serves as Apple's exclusive assembler for the foldable iPhone, fully responsible for production and quality control. The company has established dedicated production lines in its Shenzhen and Zhengzhou campuses, with mass production plans slated to commence in the fourth quarter of 2026. Luxshare Precision has also participated in the R&D and trial production of foldable products, providing precision assembly and structural component services, and is developing hinge-related technologies with the aim of entering Apple's supply chain later.

In the flexible circuit board sector, Zhen Ding Technology, as the global PCB leader, has penetrated the core supply chain for foldable smartphones with its dynamic bending FPC technology. Due to the more complex internal space in foldable phones, the use of motherboards and flexible circuit boards has increased significantly, elevating the per-unit value. The company's 2026 capital expenditure guidance is about 17 billion yuan, 2.5 times that of 2025, indicating substantial capacity expansion. Dongshan Precision also supplies Apple with core components such as FPC flexible circuit boards and antenna modules for foldable smartphones.

In the battery sector, Sunwoda Electronics emerges as the main supplier of battery packs for Apple's foldable smartphones, expected to hold a 40% to 50% share. As foldable phones consume more power and require larger battery capacities, the per-unit value of battery packs is also anticipated to rise. Additionally, Universal Scientific Industrial (Shanghai) Co., Ltd., as Apple's exclusive supplier of eSIM modules, boasts a yield rate of 99.95% for its 0.4-millimeter ultra-thin SiP packaging technology. Since the iPhone Fold will only be released in an eSIM version, completely eliminating physical SIM slots, Universal Scientific's business growth in this area is highly certain.

Notably, in the display panel sector, Samsung Display remains the exclusive supplier of inner screens for foldable phones, with BOE not yet included in the initial supplier list. However, sources suggest that as BOE improves its yield and certification progress, it may break Samsung's exclusive supply arrangement in subsequent batches. This uncertainty adds variables to investment in the panel sector.

04. The Apple Foldable Era for China's Supply Chain Has Just Commenced

The mass production of Apple's first foldable iPhone signifies not just the launch of a product but also a pivotal step in form innovation for the consumer electronics industry. For Chinese supply chain companies, this represents both an opportunity and a test—those that can pass Apple's stringent certification system will achieve qualitative improvements in technical capabilities and brand endorsement. However, securing supply qualifications is just the starting point; maintaining yield rates and delivery stability during continuous mass production is the true test of long-term competitiveness.

From UTG glass to hinge systems, from FPCs to complete device assembly, Chinese companies' depth of participation in Apple's foldable supply chain surpasses that of any previous iPhone generation. This is both a concentrated release of the technological accumulation of fruit chain companies over the past decade and a microcosm of China's precision manufacturing capabilities moving upmarket.

Of course, the initial stocking volume of 10 million units remains a niche within Apple's vast product portfolio, and its contribution to supply chain companies' performance will take time to materialize. But the window has opened—with the continuous rise in foldable phone penetration rates, the expansion of Apple's subsequent model plans, and the potential for more Chinese suppliers to enter the certification system, the growth potential of this supply chain extends far beyond the first model. For suppliers with true core technological barriers and sustained delivery capabilities, the Apple foldable era may have only just begun.
