Problems solved by technology

In the industry, CNC machine tools (computer numerical control machine, CNC) are generally used to mill the inner surface of the metal shell to form the microstructure, which takes a long time, resulting in low shell processing efficiency
The shell is formed by insert molding plastic and metal. The plastic is used to form the complex microstructure of the shell, which can improve the processing efficiency of the shell. However, due to the large difference in the material of the plastic and the metal, the combination of the two is not strong , easy to cause plastic and metal peeling, affecting the performance of the shell

Embodiment Construction

[0018] see Figure 1 to Figure 3 , the casing 100 according to the first embodiment of the present invention includes a metal part 10 and a plastic part 30 combined with the metal part 10 . In the embodiment of the present invention, the housing 100 is a mobile phone housing. It can be understood that the casing 100 may also be a casing of other electronic devices such as a tablet computer and a notebook computer.

[0019] The metal piece 10 is a rectangular frame made of aluminum alloy. It can be understood that the metal piece 10 can also be made of aluminum, magnesium / magnesium alloy, stainless steel and other metals or alloys. A plurality of laser holes 102 formed after laser treatment and a plurality of nanoholes 106 formed after electrochemical etching are formed on the inner surface of the metal piece 10 .

[0020] Please also see Figure 5 and Figure 7 , a plurality of laser holes 102 in this embodiment are connected to each other to form interlaced strip grooves...

Abstract

The invention provides a shell. The shell comprises a metal part and a plastic part which is combined with the surface of the metal part in an injection molding mode. A plurality of laser holes are formed in the combined surface of the metal part and the plastic part, and a plurality of nanopores formed in an electrochemical etching mode are formed in the combined surface of the metal part and the plastic part and in the laser holes. The invention further provides a manufacturing method of the shell, and the binding force between the metal part and the plastic part of the shell manufactured with the manufacturing method is strong.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing formed by inserting metal parts and plastic parts and a manufacturing method of the casing. Background technique [0002] Metal casings made of aluminum / aluminum alloys, magnesium / magnesium alloys, stainless steel and other metals have the advantages of light weight, beautiful appearance, and high mechanical strength. They are often used to make casings for electronic products such as tablet computers and mobile phones. The inner surface of an electronic product housing is usually provided with complex microstructures. In the industry, a numerical control machine (computer numerical control machine, CNC) is generally used to mill the inner surface of the metal shell to form the microstructure, which takes a long time and results in low shell processing efficiency. The shell is formed by insert molding plastic and metal. The plastic is used to form the compl...
