Apple Found a Way to Save Big on a Key iPhone Fold Component
Apple’s long-anticipated foldable iPhone, often referred to as the “iPhone Fold,” is moving closer to reality — and recent leaks suggest that Apple has found a clever way to dramatically cut production costs. According to renowned analyst Ming-Chi Kuo and multiple supply-chain sources, the company is redesigning the foldable hinge using a liquid metal alloy, allowing Apple to reduce one of the most expensive parts of the device while also improving durability.
This new approach could not only make the iPhone Fold more affordable but also position Apple as a leader in premium foldable engineering — something competitors like Samsung and Huawei have struggled to perfect.
Apple’s Biggest Cost Problem: The Hinge
One of the most technically complex and expensive parts of any foldable phone is its hinge mechanism. It determines how well the screen folds, how long the phone lasts, and how visible the crease line remains after thousands of folds.
For years, this component has been a bottleneck for Apple. Samsung’s Ultra Thin Glass (UTG) displays and Huawei’s dual-axis hinges have shown improvements, but Apple has been aiming for something far more refined — a near-crease-free hinge that also supports long-term mechanical stability.
Early industry estimates placed Apple’s custom hinge at around $100–$120 per unit, making it one of the most expensive single components in the phone’s design. However, new reports indicate that Apple has found a way to reduce this cost by up to 40%, thanks to a breakthrough in material choice and production methods.
The Secret Ingredient: Liquid Metal
Apple’s cost-saving innovation centers on its use of liquid metal, also known as metallic glass or amorphous metal. Unlike traditional crystalline metals, liquid metal has a disordered atomic structure that gives it unique mechanical properties — it’s stronger, lighter, and more flexible than most alloys.
This material was first introduced by Apple years ago in small components like SIM ejector tools and Apple Watch parts. But now, according to supply-chain insiders, Apple is scaling it up for use in the foldable hinge system of the upcoming iPhone Fold.
Liquid metal offers several key advantages:
- Extreme durability – It resists wear and fatigue even after hundreds of thousands of folding cycles.
- Smooth motion – It enables a consistent folding experience with less friction, preventing creases from forming on the screen.
- Lightweight strength – It’s stronger than steel but lighter than aluminum, perfect for a premium yet thin foldable phone.
- Manufacturing efficiency – It can be die-cast in complex shapes, reducing machining time and waste.
The Manufacturing Advantage
Apple’s use of liquid metal hinges will be supported by Dongguan EonTec, a company known for its work in amorphous alloy production. Reports suggest that Apple and EonTec have been co-developing liquid metal components for years, and mass production is now approaching readiness.
By using die-casting technology, Apple can produce hinges with extreme precision while cutting down on manufacturing steps — a huge cost advantage compared to traditional CNC machining used in older designs.
As a result, the estimated cost per hinge is now expected to fall to around $70–$80, significantly below early projections. This cost reduction will allow Apple to reallocate budget to other areas, such as advanced display panels, new camera systems, and the titanium outer frame rumored for the foldable iPhone.
The Design Goal: Nearly Crease-Free Folding
Apple’s focus isn’t just cost reduction. Engineers are reportedly obsessed with achieving a smooth, crease-free display experience, something no other foldable has fully achieved.
The new hinge design, combined with specialized display layers, will help distribute tension evenly across the folding line. Early prototypes reportedly show a much flatter surface when unfolded, reducing visible wrinkles that often appear on competing models like the Galaxy Z Fold series.
Although some minor crease may still remain under specific lighting, Apple’s approach seems to minimize the effect so effectively that it will be barely noticeable in daily use.
Strategic Timing and Market Position
The foldable iPhone is not expected before late 2025 or early 2026, but the timing makes strategic sense. By then, Apple will have fully rolled out its Apple Intelligence AI ecosystem, making a foldable iPhone the perfect hardware platform to showcase a new era of multitasking and creativity.
Moreover, cost efficiency is critical. Early foldable devices like Samsung’s Galaxy Z Fold 5 launched at premium prices due to high production costs. Apple’s ability to reduce hinge expenses by 30–40% means it could either protect its profit margins or price the iPhone Fold more competitively, bringing it closer to the mainstream premium market.
What to Expect Next
Industry sources say Apple is currently testing multiple foldable prototypes — some with vertical “Flip” designs and others with tablet-style “Fold” layouts. The liquid metal hinge will likely appear in both versions, as Apple fine-tunes which design best fits its long-term lineup.
Leaks also suggest the company is working on specialized display protection layers sourced from LG and Samsung Display, which could enhance flexibility and reduce reflection, ensuring that the foldable screen maintains Apple’s typical visual quality.
If Apple’s engineers succeed, the iPhone Fold could become the most durable and premium foldable phone ever produced, setting a new benchmark for the industry.
Final Thoughts
Apple’s move to use liquid metal for the iPhone Fold’s hinge is more than just a cost-cutting measure — it’s a smart blend of innovation, efficiency, and long-term vision. By solving one of the biggest challenges in foldable design, Apple not only reduces expenses but also ensures that the device meets its high standards for durability and aesthetics.
When the iPhone Fold eventually debuts, it could redefine the market once again — not just through cutting-edge design, but through a mastery of materials that few companies can match.
