The material of the seal of the volume button of the mobile phone
Liquid silicone: Liquid silicone is a commonly used sealing material, which has good elasticity and water resistance, and can effectively prevent moisture from entering the inside of the mobile phone through the volume key of the mobile phone.
Solid silicone: Solid silicone is also commonly used in mobile phone seals, which have good wear resistance and high-temperature resistance.
Rubber: Rubber materials have good elasticity and sealing, but may be slightly inferior to silicone in terms of chemical and temperature resistance.
The process of sealing the volume button of the mobile phone
Liquid silicone lagging process: This is a commonly used waterproof treatment method that involves pouring liquid silicone material into a mold, completely wrapping the volume keys, and then curing to form a waterproof barrier.
Hot press transfer molding: This process injects a silicone material into a mold at high temperatures and combines it with metal or plastic keys to form a seal.
Anodizing: This is a surface treatment process that improves the wear and corrosion resistance of metal keys.
The market situation for mobile phone volume button seals
With the continuous expansion of the smartphone market, the requirements for the waterproof performance of mobile phones are also getting higher and higher, which directly drives the growth of the mobile phone volume button seal market. According to the report of the Huajing Industry Research Institute, the demand for seals in China will reach a certain scale in 2020, and the demand for rubber seals will account for 24.85% of the total.
Conclusion
The volume button seal is a key component in ensuring the waterproof performance of the phone. With the development of technology and the increase in market demand, the materials and processes of seals are also constantly improving. Liquid silicone has become one of the most popular sealing materials due to its excellent waterproof performance and good hand feel. In the future, with the development of new materials and the improvement of technology, the performance of mobile phone volume button seals will be further improved, bringing users a better experience.
