Shell and manufacture method thereof

Abstract

The invention provides a shell, comprising a basal body and a decorative film formed on the surface of the basal body. The basal body is integrally formed by a metal component and a plastic component; one surface of the basal body is formed by the metal component and the plastic component together; the decorative film is formed on the surface of the basal body and comprises a priming layer directly formed on the surface of the basal body, a non-conductive vacuum film coating layer formed on the surface of the priming layer and a transparent protective lacquer layer formed on the non-conductive vacuum film coating layer. The shell not only has higher mechanical strength, but also can satisfy the radio frequency requirement of an electronic device and has uniform metal appearance effect. The invention further provides a method for manufacturing the shell.

Description

technical field [0001] The present invention relates to a casing, in particular to a casing for an electronic device and a manufacturing method thereof. Background technique [0002] The shells of electronic devices such as mobile phones are mostly made of plastic or metal alone. Although a single metal shell has good mechanical strength, the metal shell has a shielding effect on electromagnetic waves. For some electronic devices with radio frequency transmitting and receiving functions, such as mobile phones and computers with wireless Internet access, they cannot meet their radio frequency requirements. Although the simple plastic casing can meet the radio frequency requirements of the above-mentioned electronic devices, its mechanical strength is not enough, and it is easy to break when the user accidentally drops it. However, if the metal parts and plastic parts are molded first and then assembled to form a housing, although this can meet the requirements of mechanical ...

Problems solved by technology

Although a single metal shell has good mechanical strength, the metal shell has a shielding effect on electromagnetic waves. For some electronic devices with radio frequency transmitting and receiving functions, such as mobile phones and computers with wireless Internet access, they cannot meet their radio frequency requirements.

Although the simple plastic shell can meet the radio frequency requirements of the above-mentioned electronic devices, its mechanical strength is not enough, and it is easy to break when the user accidentally drops it

However, if the metal parts and plastic parts are molded first and then assembled to form a housing, although this can meet the requirements of mechanical strength and radio frequency, it will increase the assembly steps, and it is difficult to achieve a consistent appearance even after surface treatment.
