Kuo: Foldable iPhone to Feature Liquid Metal Hinges for Better Durability

Apple plans to use liquid metal in the hinges of its upcoming foldable iPhone to improve durability and reduce screen creasing, according to analyst Ming-Chi Kuo.

Foldable iPhone 2023 Feature Iridescent 1
Apple has reportedly chosen liquid metal, which is manufactured using a die-casting process, as a key component in addressing common issues with foldable devices. The design choice aims to enhance screen flatness and minimize the crease marks that typically plague folding displays.

Kuo notes that Apple has previously used liquid metal in smaller components like SIM ejector pins, but the foldable iPhone will mark the company's first major use of the material in a critical mechanical part. Dongguan EonTec will reportedly be the exclusive supplier of liquid metal.

Previous reports suggest Apple's foldable iPhone will feature a 7.8-inch main display when unfolded and a 5.5-inch cover display. The device is expected to adopt a book-style design similar to Samsung's Galaxy Z Fold, rather than a clamshell form factor.

According to earlier information from Kuo, the foldable iPhone may include two rear cameras, a single front-facing camera, and Touch ID integrated into the power button. The device could measure just 4.5mm thick when unfolded, and between 9mm and 9.5mm when closed.

Mass production is anticipated to begin in the fourth quarter of 2026, suggesting a potential launch in late 2026 or early 2027.

I can't wait for an Apple solution to be honest. I love mine. Never going back to a non fold phone.

I never understood what do people do with these huge tables phones? Is it still a phone or is it a tablet? Or a tablet with a sim? I personally don't think a folding tables would be what I consider "an iPhone".
This is for people who want something the size of a phone in their pocket (that is their phone) that can be transformed into something with a larger screen. I've never understood why people find this a difficult concept to grasp and are so "anti". I'm not keen on one myself (at present at least) but I can understand entirely what it is for and why plenty of people will want it.

I use mine as a phone while I am out and about and unfold it for media consumption when I am on the couch or riding public transport. It's nice using the browser, email, WhatsApp and Instagram simultaneously without flipping back and forth between apps all the time.

One basic thing I always do is open the bank app in one window and my splitwise app right next to it. Makes it super easy to put in my expenses without going back and forth between apps and forgetting the number I just looked at while doing so. Another use case is browsing the web for hotels while comparing it to the results in the booking app

('https://www.macrumors.com/2010/08/17/liquid-metal-used-in-iphone-3g-sim-tool-next-iphone-too/')). I can't believe thats more than 10 years ago, time really flies...

August 2024.

"The U.S. Patent and Trademark Office officially published a series of 76 newly granted utility patents for Apple Inc. In this particular report we briefly cover a "Liquid Metal" related patent and another covering Spatial Audio. And as always, we wrap up this week's granted patent report with our traditional listing of some of the remaining granted patents that were issued to Apple this week along with granted design patents for packaging.

Fluid Forming A Glass Component For A Portable Electronic Device

Apple's granted patent relates to techniques in which a fluid such as a liquid metal or a molten salt is used to shape a glass workpiece. Devices made this way could include a HomePod, Home Control device, an iMac, MacBook, iPad or iPhone.

Apple’s patent includes techniques that can be used to shape a glass workpiece to produce a three-dimensional glass component. By the way of example, the three-dimensional glass component may be a glass cover member or a glass housing.

Apple’s patent FIGS. 1A-B below are just two simple device examples of three-dimensional glass components that may be a glass cover member or a glass housing.


Apple’s invention is extensively covered over two patents: (#1: 20220193825) “Laser-Based Cutting of Transparent Components for an Electronic Device,” and (#2: 20220194841) “Fluid Forming a Glass Component for a Portable Electronic Device.”12064791.


Liquid metal (as in a metal in a liquid or molten state, which is what this patent refers to) is not the same as Liquidmetal, which is a particular metal alloy to which Apple has exclusive rights for use in consumer electronics.

Kuo made this rather ambiguous by writing ‘liquid metal’ but was clearly referring to the alloy Liquidmetal.
