Double-layer mobile phone shell and manufacturing method thereof

Abstract

The invention discloses a double-layer mobile phone shell and a manufacturing method thereof. The double-layer mobile phone shell comprises a metal inner shell and a transparent plastic outer shell; and the metal inner shell and the transparent plastic outer shell are tightly combined together. The manufacturing method comprises the step of A, manufacturing the metal inner shell and the transparent plastic outer shell respectively; and B, sleeving the transparent plastic outer shell at the outside of the metal inner shell and enabling the transparent plastic outer shell and the metal inner shell to be tightly combined. According to the double-layer mobile phone shell, the texture of the metal inner shell at the inner layer can be shown through the transparent plastic outer shell at the outer layer, and the transparent plastic outer shell at the outer layer can protect the metal inner shell; and when the mobile phone shell is abraded, only the transparent plastic outer shell is abraded. Due to the material consistence of the transparent plastic outer shell, damage such as scratches is not obvious and the impression is not affected. At the same time, due to the flexibility of the transparent plastic outer shell, the transparent plastic outer shell also can buffer impact force when a mobile phone is impacted. Therefore, the metal inner shell and parts inside the mobile phone shell are protected efficiently.

Description

technical field [0001] The invention relates to a manufacturing technology of a mobile phone case, in particular to a double-layer mobile phone case and a method for manufacturing the double-layer mobile phone case. Background technique [0002] Since the birth of the mobile phone, its appearance has been as important as its own function. In the era of feature phones, due to the characteristics of small screens and keyboard input, the appearance of mobile phones can be designed in various forms, so the appearance of mobile phones is diversified. With the popularity of smart phones, because smart phones use touch screen input, the screen occupies most of the space on the front of the mobile phone, the variability of the appearance of the mobile phone is greatly reduced, and the homogeneity of the appearance of the mobile phone is becoming more and more serious. And many factories have generally made a fuss about the material of the mobile phone case. The mobile phone case m...

Problems solved by technology

However, due to the high rigidity of the metal mobile phone case, when the mobile phone is impacted, the impact force is directly transmitted to the internal parts of the mobile phone, which cannot play a buffer role.

In addition, in order to achieve a better look and feel, the metal shell needs to be electroplated or sprayed with color on the surface, but when the phone shell is worn, the electroplating or color on the surface is damaged, exposing the metal bottom, which greatly affects the look and feel
