AI Technical Summary

Technical Problem

The bonding force between the aluminum frame and the titanium shell is poor, and separation is prone to occur, affecting the processing quality of the shell.

Method used

The groove is formed by CNC processing of the shell wall and bottom of the titanium shell, and laser engraving is performed on the bottom of the groove to form a mesh texture structure, increasing the roughness of the titanium shell. Then the aluminum frame is assembled into the titanium shell, and the part of the aluminum frame is embedded in the mesh texture structure by heating and forging to enhance the bonding force.

Benefits of technology

The bonding force between the aluminum frame and the titanium shell is significantly improved, the problem of separation occurs during processing is reduced, and the overall quality of the shell is improved.

Abstract

The invention relates to the technical field of mobile phone workpiece machining, in particular to a manufacturing method of a shell and the shell. The manufacturing method of the shell comprises the steps that a titanium plate is subjected to flanging machining, and a titanium shell is obtained; cNC machining is conducted on the titanium shell so that a groove can be formed in the titanium shell; the bottom of the groove is subjected to laser engraving, and a net-shaped texture structure is formed at the bottom of the groove; assembling the aluminum frame into the titanium shell to form a middle frame and back shell workpiece; and the middle frame back shell workpiece is heated and forged, so that part of the aluminum frame is embedded into the net-shaped texture structure, and the shell is obtained. According to the arrangement, the binding force between the aluminum frame and the titanium shell of the shell can be improved.
