Abstract

The invention relates to a method for preparing a composite shell. The method comprises the steps: (1) forging and pressing stainless steel or aluminum alloy to form an outer frame; (2) die-casting the aluminum alloy to form an inner frame; (3) conducting CNC finish machining for the outer frame and the inner frame for laser welding; (4) conducting laser deep-seam welding for the outer frame and the inner frame, and thus forming a structural metal part; and (5) conducting CNC finish machining for the structural metal part, etc. The method has the advantages of small loss, easy machining, low comprehensive production cost and easy mass production.

Description

technical field [0001] The invention relates to a preparation method of a composite casing. Background technique [0002] With the continuous improvement 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 have changed from 6 to 6 with good machinability. The series of aluminum alloys are developing towards higher 7 series aluminum alloys and stainless steel materials with higher hardness and strength to meet the market's demand for high value-added mobile electronic product shells that are resistant to falling, abrasion, scratching, and deformation. aspects of demand. [0003] Because stainless steel has the advantages of high hardness, high strength, good heat resistance, good corrosion resistance, low density, light weight, and high mechanical strength, it is an ideal mat...
