Huawei's 5G folding screen mobile phone costs 2,299 euros. It is estimated that few consumers can buy it. In addition to the expensive flexible screen, the price of the internal structural parts is also a factor. Some analysts believe that the hinge shaft is the most important for the folding machine. The components of the machine, and the hinge of Huawei Mate X are designed by ourselves. The hinged shaft assembly is at least 40 US dollars. Why is the price so high?

The structure of the folding screen is mainly divided into four layers, which are a screen protective layer, a flexible flexible screen, a soft plastic supporting piece and a rotating shaft. The seamless fit of the folding phone, the hinge of the hinge plays a key role, almost determining the success or failure of the folding screen. Because it is not only slim, but also the design of the folding screen related connections, wiring, heat dissipation, etc. more than 100 components, but also consider the reliability, user grip. According to Huawei, the success of the shaft has gone from the design of the motion principle to the design of the sub-function module, to the choice of materials, and the attempt of different surface treatments, which can be described as eagle-wing folding.

Folding screen hinge hinge cost is so high, almost 10 times the price of the current 3D glass cover of the smart phone. The following small series analyze the reasons for the high cost from the following aspects;
1. More than ten kinds of metal parts are formed, which need to be formed by MIM, stamping, liquid metal and other processes;
2. For the precision of assembly, CNC precision machining is also required. Due to the easy deformation of the CNC clamping position, the critical dimensions are difficult to guarantee;
3. After the CNC processing, post-process processing, such as sand blasting, anodizing, etc., is required;
4. Due to the large number of parts, the assembly process is complicated, the tolerance is large, and some parts need to cooperate with each other to meet the requirements. It belongs to the typical tight assembly category, and the finished product yield is low after multiple processes.

The folding of the screen needs to rely on the hinge shaft to support the rotation. The requirements for the rotation accuracy and the friction coefficient are extremely high. Therefore, the requirements of the supplier are high. Compared with the notebook shaft, the hinge of the mobile phone hinge is precise and durable. Both strength and thin gauge specifications are much higher than laptop hinges. It is reported that Huawei Mate X's exclusive supplier of hinge hinges is a wonderful supplier. The next generation may develop a number of suppliers, such as BYD, Foxconn, Changying Precision and other strong process development capabilities.

Xiaobian estimates that Huawei's hinge price is around 350 yuan, and may not be making money or even paying money. For the processing of hinges, suppliers are optimistic about Huawei's future cooperation. For strategic cooperation, some singles do not have to make money to pick up. After all, the future development of folding screens is still relatively optimistic, and in addition to folding screen hinges, Huawei's other products, such as laptops. When the post-processing technology is mature, the cost may be reduced. For example, the price of the metal back shell is about 200-300, and then the cost of 10-15% is reduced for each generation. Of course, the price depends not only on the processing cost, but also on the complexity of the structure and the volume of shipments.
Folding screen mobile phones are coming to the forefront, and various manufacturers are gearing up. According to Xiaobian statistics, there are companies involved in the production of folding screen hinges:
Hinge shaft manufacturing company
MIM processing & liquid metal processing
The folding screen will make a major change to the existing part of the mobile phone supply chain. The types of enterprises involved include terminals, display touch companies, flexible films, FPCs, flexible adhesives, hinges, lasers, dispensing, lamination, inspection, etc. class. Such as:
