Magnesium alloy nanometer injection molding process

Abstract

The invention provides a magnesium alloy nanometer injection molding process. The magnesium alloy nanometer injection molding process includes the steps of alkali washing, specifically, a magnesium alloy substrate is immersed in alkali liquid, and oil on the surface of the magnesium alloy substrate is removed; acid washing, specially, the magnesium alloy substrate is immersed in acid liquid to beneutralized and then is dried; T treatment, specifically, the magnesium alloy substrate is treated through weakly acidic T liquid, and nanoscale micropores are etched in the surface of the magnesium alloy substrate; water washing, specifically, the magnesium alloy substrate is placed in pure water to be cleaned and then is dried; injection molding, specifically, the magnesium alloy substrate is placed in an injection molding mold to be subjected to injection molding, plastic materials are combined with the micropores in the surface of the magnesium alloy substrate through injection molding, and thus the plastic materials and the magnesium alloy substrate are tightly combined, and a product blank is obtained; and annealing, specifically, within two hours after injection molding is completed, the product blank is placed in an oven to be baked for one hour at the temperature of 140-150 DEG C.

Description

technical field [0001] The invention relates to nano injection molding technology, in particular to a magnesium alloy nano injection molding process combining plastic materials and magnesium alloys. Background technique [0002] Nano injection molding technology, also known as nano molding technology (NMT, Nano Molding Technology), is a method of combining metal and plastic with nanotechnology. NMT is to first process the metal surface through nano-treatment, and the plastic is directly injection-molded on the metal surface, so that the metal and [0003] Plastic can be molded in one piece. Compared with the traditional structure, NMT molding technology takes into account the metal appearance and texture, and can also simplify the product structure design. It is more widely used in electronic products, such as mobile phone casings, which can make the product lighter, thinner, shorter, smaller, and stronger. The received signal is stronger. [0004] Usually, nano-injection...
