Technology for inlaying aluminum alloy in magnesium alloy in pressure casting manner

Abstract

The invention discloses a technology for inlaying an aluminum alloy in a magnesium alloy in a pressure casting manner. The technology for inlaying the aluminum alloy in the magnesium alloy in the pressure casting manner includes the following steps that S1, pressure casting forming of the magnesium alloy is conducted; S2, local inlaying of the aluminum alloy is conducted; S3, CNC machining is conducted; S4, formation is conducted; S5, surface paint spraying is conducted; S6, drilling cutting highlighting is conducted; S7, salt spray testing is conducted; and S8, complete inspection packaging is conducted. By means of the technology for inlaying the aluminum alloy in the magnesium alloy in the pressure casting manner, due to the fact that the aluminum alloy is inlaid in a magnesium alloy shell and the antioxidant effect of the aluminum alloy is better than that of the magnesium alloy, it can be ensured that the highlighted part of a metal notebook computer face shell does not generate rust; due to the fact that a dovetail-shaped aluminum engaging structure is arranged, the aluminum alloy can be better engaged with the magnesium alloy firmly; and due to the fact that the aluminum engaging structure is made into a dovetail shape, the dovetail structure of aluminum can be completely wrapped by magnesium during pressure casting, and disengagement of the inlaid aluminum part is prevented.

Description

technical field [0001] The invention relates to the technical field of notebook computer cover processing, in particular to a magnesium alloy die-casting inlaid aluminum alloy process. Background technique [0002] With the improvement of people's living standards, the requirements for electronic equipment have also increased accordingly. For example, the requirements for lightness, thinness, performance, aesthetics and hand feeling of notebook computers are getting higher and higher. Now most notebook computers on the market are made of plastic shells, which have poor heat dissipation and insufficient strength, and at the same time emit plastic smell. . [0003] Due to the various disadvantages of plastic parts, major manufacturers have thought of replacing plastic parts with metal, but metal is not as good as plastic parts in terms of molding and surface treatment. Metal forming mainly includes sheet metal stamping and metal hot-melt casting. However, the easy corrosion ...

For example, the requirements for lightness, thinness, performance, aesthetics and hand feeling of notebook computers are getting higher and higher. Now most notebook computers on the market are made of plastic shells, which have poor heat dissipation and insufficient strength, and at the same time emit plastic smell.

[0003] Due to the various disadvantages of plastic parts, major manufacturers have thought of replacing plastic parts with metal, but metal is not as good as plastic parts in terms of molding and surface treatment. Metal forming mainly includes sheet metal stamping and metal hot-melt casting. However, the easy corrosion of metal sheets has become a major problem hindering the cover of metal laptops, and the surface treatment of metal appearance has also triggered various difficult processes
