With the rise of foldable screen phones, the application of magnets in foldable phones has become increasingly important. They are not only responsible for keeping the screen firmly open and closed, but also affect the overall durability and user experience of the device. Therefore, it is crucial to ensure the long-term stability and durability of magnets for foldable phones.First, material selection is the key. Magnets for foldable phones should use high-performance rare earth permanent magnet materials, such as neodymium iron boron magnets, which have strong magnetic force, high coercive force and good temperature stability. At the same time, the surface of the magnet should be nickel-plated or other anti-corrosion treatments to enhance its corrosion resistance and prevent the weakening of magnetic force due to oxidation during long-term use.Secondly, the fixing method of the magnet is also crucial. In the design of foldable phones, the magnet should be firmly embedded in the hinge structure to avoid affecting the stability due to loosening or falling off during use. In addition, the gap between the magnet and the surrounding metal parts should be reasonably controlled to prevent wear caused by friction.In addition, reasonable structural design is also an important factor in ensuring the long-term stability of the magnet. The hinge design of foldable phones should fully consider the magnetic force distribution and opening and closing feel of the magnets. Through precise magnetic circuit design, the stable opening and closing of the screen and the hovering at any angle can be achieved. At the same time, the cushion and lubricating materials inside the hinge can also effectively reduce the wear of the magnets during the opening and closing process and extend their service life.Finally, quality control and testing are key links to ensure the durability of magnets for foldable phones. During the production process, the magnetism, size and surface quality of the magnets should be strictly tested. At the same time, by simulating the opening and closing test in actual use scenarios, the long-term stability and durability of the magnets can be evaluated to ensure that the product meets user needs.In summary, by selecting suitable materials, reasonable fixing methods, precise structural design and strict quality control, the long-term stability and durability of magnets for foldable phones can be ensured, providing users with a more reliable and durable folding screen mobile phone experience.
