Abstract

The invention discloses a metal insert casting integral molding manufacturing method, which comprises the following steps: S1, using a die-casting process or a forging process to manufacture a metal inner frame; S2, putting the metal inner frame into a casting mold, using molten The titanium alloy is cast, and the titanium alloy outer frame is cast on the metal inner frame to form a metal integral molding structure of the metal inner frame and the titanium alloy outer frame. The production method can realize the use of titanium alloy shells on electronic products, overcome the problems of high cost, poor plasticity and difficult machining of existing titanium alloy materials, reduce the loss of titanium alloy shells, be easy to machine, and comprehensively produce Low cost, easy mass production.

Description

Technical field [0001] The invention relates to the manufacture of an electronic device housing, in particular to a method for manufacturing a metal insert casting and integral molding. Background technique [0002] Because titanium alloy has the advantages of high hardness, high strength, good heat resistance, good corrosion resistance, low density, light weight, high mechanical strength, etc., it is an ideal material for preparing mobile phone shells. It has been used in many high-end luxury brand mobile phones. ; [0003] At the same time, with the continuous improvement and enhancement of the functions of portable 3C electronic products such as high value-added wearable devices, mobile phones, smart watches, and mobile electronics, and fierce market competition, metal materials have been widely used in mobile phone shell materials, and the processability has improved 6 series aluminum alloys are developed to higher 7 series aluminum alloys or higher hardness stainless steel ma...
