The composite materials generally used in the finished mobile phone cover are mainly plastic, metal and glass.

The first is plastic material, plastic material is lightweight, durable, low cost, so it is widely used in the production of mobile phone cover. Common plastic materials are polycarbonate, polyimide, polypropylene and so on. These plastic materials can be made into mobile phone cover through injection molding, acrylic wire drawing and other processes, with good toughness and wear resistance, but also can be customized with a variety of colors and textures, and has a high degree of design freedom in appearance.

Followed by metal materials, metal materials have excellent compression and fall resistance, while having a high-grade sense and texture in appearance. Common metal materials are aluminum alloy, stainless steel, etc. These metal materials can be made by stamping, wire drawing, anodizing and other processing processes. The metal mobile phone cover plate not only has a high-grade appearance, but also has good wear resistance and durability, which is suitable for mobile phone users who need a high-grade sense and durability.

Finally, the glass material, the glass material has the characteristics of high transparency, high hardness, good scratch resistance, etc., and is also widely used in the production of mobile phone cover. The main glass materials are tempered glass, Combox glass, etc. These glass materials can be made into mobile phone cover through hot bending process, laser cutting and other technologies. The glass cover of the mobile phone has a high degree of transparency, finish and texture, and also has excellent scratch resistance and drop resistance, which is suitable for users who pursue a delicate appearance and high texture.

In summary, mobile phone cover products are generally made of three composite materials: plastic, metal and glass. Different materials have their own characteristics and advantages, and the suitable cover material can be selected according to the needs and preferences of users. In the future, with the continuous development of science and technology and the innovation of material processes, mobile phone cover materials will also continue to be updated, bringing users more diverse choices.
