Embodiment Construction
[0042] In order to better illustrate the present invention, the present invention is described in detail with the following preferred embodiments and in conjunction with the accompanying drawings, specifically as follows:
[0043] Such as figure 1 As shown, a method for electroless plating of a die-casting magnesium-aluminum alloy and a nano-injection molded part of LDS plastic provided in this embodiment includes the following steps:
[0044] S1: Making a die-cast magnesium-aluminum alloy shell;
[0045] S2: Injecting LDS plastic parts on the die-cast magnesium-aluminum alloy shell to form the shell;
[0046] S3: spraying a primer on the surface of the housing;
[0047] S4: Electroless plating is performed on the primer-coated casing to make metal circuits.
[0048] In step S2 of this embodiment, the primer for resisting electroless plating is sprayed on the entire surface of the casing composed of LDS plastic parts. This method of spraying the primer is easy to operate, ...

The invention provides a method for manufacturing a metal circuit. The method comprises the following steps: manufacturing a pressure-casting magnesium aluminum alloy shell; injection-molding an LDS plastic part on the pressure-casting magnesium aluminum alloy shell to form a shell; coating the surface of the shell with primer in a spraying manner; performing chemical plating on the shell coated with the primer to manufacture the metal circuit, wherein the primer can be a PU material, or acrylic acid or oxirene ester primer. A thickness of the primer is 10-30 mu m. The layer of primer is coated on a nano-injection-molding part of the pressure-casting magnesium aluminum alloy and the LDS plastic, such that effective protection on the pressure-casting magnesium aluminum alloy shell is realized in a manufacturing process of the metal circuit through chemical plating, reaction between the pressure-casting magnesium aluminum alloy and chemical plating liquid agent in the chemical plating process is avoided, and the manufacturing effect of the metal circuit is ensured.
Description
technical field [0001] The invention relates to the fields of die-casting magnesium-aluminum alloy nano-injection molding, LDS technology and antenna production, in particular to a method for manufacturing metal circuits on nano-injection-molded parts of die-casting magnesium-aluminum alloy and LDS plastics. Background technique [0002] Die-casting magnesium-aluminum alloy nano-injection molding technology can firmly combine aluminum alloy and plastic to build beautiful-looking thin-walled shell parts, which are widely used in mobile phone shells. The LDS plastic is a modified plastic containing an organic metal compound, which can release metal particles after laser irradiation. LDS technology can realize the production of metal lines on the surface of plastic parts with the help of injection molding, laser treatment, electroless plating and other technologies, and is widely used in the production of mobile phone antennas. [0003] Die-casting magnesium-aluminum alloy and...
