When it comes to choosing a mobile phone film, the sapphire mobile phone film stands out with numerous advantages. Compared with ordinary PET films, the sapphire film has a much higher hardness. With a Mohs hardness of 9, second only to diamond, it can effectively resist scratches from sharp objects such as keys and knives, keeping the screen clear for a long time. Compared with tempered glass films, it not only has strong toughness and is less likely to break, but also has a higher light transmittance, providing a clearer visual effect and excellent color restoration, bringing an immersive visual experience.

In practical applications, sapphire mobile phone films are mostly used in high - end mobile phone models, providing reliable protection for the phone screen. For example, some photography enthusiasts, when using a mobile phone equipped with a sapphire film to shoot, don't have to worry about the lens protective film being scratched and affecting the imaging quality. Business people also favor it as it can keep the appearance of the mobile phone looking new for a long time.

How is such an excellent sapphire mobile phone film processed? First, use the single - wire machine TJ6060 for squaring to cut the sapphire ingot into a suitable square ingot. This step is like laying the foundation for subsequent processing, determining the basic shape and size of the square ingot. Then, use a grinding machine to polish the square ingot to make its surface smoother. Subsequently, use a high - speed and high - precision multi - wire cutting machine TJ2000 for cutting, processing the square ingot into a sapphire mobile phone film rough blank with a thickness of 0.45mm. During this process, the accuracy and warpage are strictly controlled within 0.02mm, perfectly meeting the requirements of subsequent processing. Finally, a sapphire mobile phone film with excellent performance is produced to protect the mobile phone screen.
