Upper casing of portable computer of magnalium material and plastic and preparation thereof

Abstract

Disclosed are an upper casing of an outer casing of a handheld computer and a manufacturing method thereof. The upper casing is combined by magnesium aluminum alloy materials and plastics, and is made of high-quality magnesium aluminum alloy materials which are casted or pressed into a magnesium aluminum alloy panel with curved edges at the surrounding. After going through passivating treatment, the magnesium aluminum alloy panel is placed in a plastic die of the upper casing of the outer casing of the handheld computer to inject through a hot pressing injection machine, thereby enabling the periphery of the magnesium aluminum alloy panel to be stably combined with plastics to form a semi-finished product. The semi-finished product is manufactured into the upper casing of the outer casing of the handheld computer which is combined by the magnesium aluminum alloy materials and the plastics after scientific polishing and finishing. The upper casing of the outer casing of the handheld computer which is manufactured by combining the characteristics of the magnesium aluminum alloy materials and the plastics achieves the communication effect of pressure resistance, strong impact resistance, not being easy to deform, and not affecting wireless operation, meets the requirements of modern information society, overcomes shortages of non-pressure-resistance, non-wear-resistance and easy deformation of the outer casing of the plastic outer casing of the handheld computer, and also overcomes the shortage that the outer casing of the handheld computer manufactured by the integral magnesium aluminum alloy materials affects wireless operation.

Description

technical field [0001] The invention relates to a laptop computer casing and a manufacturing method thereof, in particular to an upper casing of a laptop computer casing combined with magnesium-aluminum alloy materials and plastics and a manufacturing method thereof. Background technique [0002] The laptop case, especially the upper case of the laptop case, bears the heavy responsibility of protecting the display screen and its internal electronic components. Therefore, the case of the laptop computer, especially the upper case, must have strong pressure resistance, impact resistance, high strength, No deformation function. The shells of common laptop computers are made of plastic, and the shells of plastic laptops have the disadvantages of poor compression resistance, impact resistance, poor strength, and easy deformation. At present, there are also magnesium-aluminum alloy materials for die-casting or stamping to make integral laptop casings, but the disadvantage of the ...

AI Technical Summary

Problems solved by technology

Ordinary laptop casings are made of plastic. The disadvantages of plastic laptop casings are poor compression resistance, impact resistance, poor strength, and easy deformation.

At present, there are also magnesium-aluminum alloy materials for die-casting or stamping to make integral laptop casings, but the disadvantage of the above-mentioned all-metal laptop casing is that it has a strong shielding effect on electromagnetic waves, which affects the communication of the laptop during wireless operation.
