Abstract

The invention provides a mobile phone middle bezel and a making method thereof, a mobile phone shell and a mobile phone; the mobile phone middle bezel comprises a metal frame and a connector in an annular structure; the connector is formed on the inner surface of the metal frame via nanometer injection moulding; there is no gap between the connector and the metal frame. The metal frame and the connector of the mobile phone middle bezel are combined via the nanometer injection moulding mode, thus enhancing the bonding force between the metal frame and the connector, and realizing seamless and integrated effect on the side face of the mobile phone middle bezel. In addition, a glue dispensing technique is omitted in the mobile phone middle bezel making process, thus reducing the making cost.

Description

technical field [0001] The invention relates to the technical field of mobile phone manufacturing. Specifically, the invention relates to a metal middle frame and a manufacturing method thereof, a mobile phone shell and a mobile phone. Background technique [0002] At present, the frame of the middle frame of the mobile phone is generally made of aluminum alloy. The shape can be processed by CNC machine tool (CNC), then anodized and colored, and then the plastic connectors can be assembled to the frame by dispensing or pasting glue. In this way, it is easy to form gaps or step differences between the assembled connectors and the middle frame, which will affect the overall fineness of the appearance of the mobile phone. Moreover, it is easy to overflow glue when dispensing glue, and there is also a problem of high scratch failure. Make the manufacturing cost of mobile phone promote. Contents of the invention [0003] Embodiments of the present invention provide a metal mid...
