Metal Frame for Mobile Devices

Utilizing exclusive precision technology-Seamless Groove Design Technology, this process is designed to enhance the bonding strength between metal and plastic components—often requiring snap grooves on the metal part for secure assembly. For applications with strict appearance standards, we have refined this technique to form internal snap grooves on the inner side of the metal frame while maintaining a zero-radius (R0) surface finish on the exterior. The result is a flawless, mark-free appearance, achieving a near-perfect surface on the visible side of the product.
