The design of a metal-bodied phone offers several advantages, including increased durability, enhanced aesthetics and feel, better heat dissipation, improved structural strength, reduced electromagnetic interference, and support for water and dust resistance. This design not only makes the phone look more premium and refined but also enhances its durability and stability.
To ensure the normal functioning of the phone's antenna system (for mobile signal, Bluetooth, Wi-Fi, and GPS) and to achieve stronger signal reception, the top, bottom, or sides of a metal-bodied phone are often designed with antenna gap strips (made of plastic materials). These strips are seamlessly integrated using injection molding technology, creating a unified appearance with the phone's metal frame. This design ensures good signal quality while also enhancing the overall aesthetics of the phone.
