OPPO Find N5: Ushering in the 8mm Era for Foldable Smartphones A Milestone Breakthrough in Chinese Precision ManufacturingWith a groundbreaking body thickness of just 8.93mm, the OPPO Find N5 shatters industry records, leading foldable flagship smartphones into the 8mm era

With a groundbreaking body thickness of just 8.93mm, the OPPO Find N5 shatters industry records, leading foldable flagship smartphones into the 8mm era. Its launch marks a significant breakthrough for Chinese smartphone manufacturers in core technology. This globally thinnest foldable flagship phone not only showcases a milestone achievement in Chinese precision manufacturing but also ushers in a new chapter for high-end domestic manufacturing, demonstrating the innovative leadership of Chinese companies in the global restructuring of industrial chain value. This breakthrough is the culmination of OPPO's expertise in materials science, precision manufacturing processes, and system engineering embodied in its "Titanium Alloy Sky-Dome Hinge" technology.

I. The Millimeter Battle: The Pursuit of Extreme Thinness and Lightness

As the overall smartphone industry enters an era of stock competition, foldable smartphones, with their innovative form factor, have become the most promising growth sector. Counterpoint Research data shows that global shipments of foldable smartphones exceeded 25 million units in 2024, a year-on-year increase of 37%. However, thickness, weight, and crease remain major pain points hindering market penetration. The OPPO Find N5 series successfully addresses these challenges.

The OPPO Find N5 series boasts a folded thickness of just 8.93mm, making it the world's thinnest foldable flagship phone and ushering in the 8mm era for foldable phones, offering consumers a more portable user experience. This breakthrough is attributed to OPPO's significant innovation in hinge technology the industry's thinnest, most reliable, and flattest "Titanium Alloy Sky-Dome Hinge."

To achieve this extreme thinness and lightness, OPPO pioneered the use of 3D-printed titanium alloy hinges. Through deep collaboration with leading global metal additive manufacturing company, PLT, a series of technical challenges were overcome in less than a year. Traditional hinge manufacturing processes could not meet the stringent thickness and precision requirements of the Find N5, while 3D-printed titanium alloy technology allows for the precise construction of titanium alloy components in minimal units, successfully achieving the complex shape and extreme thinness of the hinge components.

Through 28 precision processes and 25 hours of continuous printing, OPPO and PLT successfully mass-produced the world's thinnest titanium alloy structural component (as thin as 0.15mm), doubling the industry's record for commercially mass-produced products. PLT's Chairman and General Manager, Xue Lei, stated: "0.15 millimeters is a small step in the thickness of a thin plate, but a giant leap for the entire industry's precision manufacturing. This strong alliance in the precision manufacturing field has doubled the minimum scale record of commercially mass-produced products in the industry. It has also established a complete set of process standards and technical specifications for the demand of metal additive manufacturing in the consumer electronics field."

This breakthrough reflects OPPO's strategic choice of a precision manufacturing technology route. In terms of materials and structure, OPPO's "Sky-Dome Architecture" has also undergone a comprehensive upgrade. The Find N5 utilizes innovative materials such as an aerospace-grade aluminum alloy frame, ultra-ceramic glass outer screen, and Sky-Dome composite fiber back cover, allowing the device to maintain extreme thinness while boasting excellent impact, drop, and scratch resistance.

OPPO's Innovation Product Development Director, Cheng Jiao, said: "Thanks to the titanium alloy material, the Find N5's hinge achieves ultra-thinness and miniaturization while significantly improving overall strength. From the core component wing plates inside the hinge to the outer rotating shaft frame that can be touched, everything is more reliable and durable. This meticulously crafted device embodies top human material and precision manufacturing technology with every opening and closing."

OPPO has reportedly incubated over 2600 new structural forms and over 1500 new material application patents, laying a solid technical foundation for the "Sky-Dome Architecture."

II. Technological Limits: Breakthrough Innovations, Leading Industry Development

For OPPO, the pursuit of thinness is never-ending. In the design process of the Find N5, OPPO did not treat "thinness" as the ultimate goal, but rather as a starting point for technological innovation. Behind every innovative foldable product lies a continuous push against technological limits.

Cheng Jiao, head of OPPO's Innovation Product Center, reviewed the innovation journey of the Find N series at a technical exchange meeting. Each generation has achieved breakthroughs in foldable screen technology: Find N pioneered UTG ultra-thin flexible glass and a waterdrop hinge, delivering the best crease performance in the industry; Find N2 innovatively introduced carbon fiber and titanium alloy materials, resulting in a foldable phone lighter than a straight phone; Find N3 applied OPPO's self-developed ultra-strong steel and microcrystalline glass, and passed the million-fold worry-free certification, further enhancing the durability of foldable screens.

Thanks to the technological accumulation of the "Sky-Dome Architecture" in flexible screens and hinge systems, the Find N5 once again leads the industry in crease control. In design, OPPO introduced the "Ideal Circle" concept, optimizing the transition curvature of the screen axis closure by simulating the posture and contour of a water droplet falling naturally, making the inner screen crease flatter when unfolded. Compared to the Find N3, the crease width of the Find N5 is narrowed by 10%, and the depth is reduced by 60%.

Meanwhile, the Find N5 is the first to pass a crease-related authoritative certification the TV Rheinland "Invisible Crease" certification. This certification covers multiple dimensions, including crease depth, width, display performance, and touch performance. The Find N5's crease depth is controlled below 0.15mm, the width is within 20mm, and the crease angle is less than 2.5, ensuring smoother display and touch.

The Find N5 not only achieves breakthroughs in foldable screen technology but also becomes the only foldable product to simultaneously obtain two top-level foldable certifications from TV Rheinland, ensuring a worry-free user experience during long-term use. Furthermore, OPPO innovatively adopts a flexible combination of "adhesive tape + dotting glue," enabling the Find N5 to achieve IPX6, IPX8, and IPX9 triple waterproof certifications.

In terms of technological innovation, OPPO has also collaborated with the China Academy of Standardization and the TV Rheinland laboratory to jointly develop and release the industry's first flatness evaluation system for foldable screens, aiming to push the crease performance of the entire industry to a new level, allowing more users to truly transition from trying out foldable screens to using them regularly.

III. The Leap of Chinese Precision Manufacturing

Currently, China's mobile phone manufacturing industry is constantly developing towards high-end, intelligent, and precise directions. The technological breakthrough of the Find N5 series is essentially a typical practice of new productive forces in the field of consumer electronics. New productive forces emphasize an innovative, efficient, green, and sustainable development model. OPPO systematically integrates advanced technologies such as additive manufacturing, composite materials, and precision machining to build a complete technological system from material innovation to process innovation. This demand-oriented collaborative innovation model of industry, academia, and research is the key path for China's precision manufacturing to leap to the high end.

Experts predict that OPPO's latest achievements and technological strength in the world's thinnest foldable flagship phone will further help improve the industry competitiveness and market penetration rate of Chinese mobile phone manufacturers in different countries and regions around the world. The success of the OPPO Find N5 is not only its own technological breakthrough but also a symbol of China's precision manufacturing strength, setting a new benchmark for Chinese enterprises in global technological competition.
