The invention provides a surface treatment method for a plastic shell. The surface treatment method for the plastic shell includes the steps that the plastic shell is subjected to surface smoothening treatment; the plastic shell subjected to the surface smoothening treatment is sprayed with a base coat; the plastic shell sprayed with the base coat is subjected to primary baking; the plastic shell is sprayed with an intermediate coat after the primary baking; the plastic shell sprayed with the intermediate coat is subjected to secondary baking; the plastic shell is coated with a UV protective layer after the secondary baking; and the plastic shell coated with the UV protective layer is subjected to tertius baking. By means of the surface treatment method for the plastic shell, the surface of the plastic shell is made to be of the metal color by spraying the base coat and the intermediate coat, and consequently the manufacturing cost of the shell is lowered while the appearance of the shell is ensured; and besides, the communication function of corresponding smart appliances is not affected.
Description
technical field [0001] The invention relates to the field of industrial processing, in particular to a surface treatment method for a plastic casing. Background technique [0002] With the development of science and technology, in order to meet people's growing consumer demand, manufacturers have developed a variety of smart home appliances, such as smart speakers and smart fans. One of the biggest features of the above smart home appliances is that they can be used with Other terminals are connected wirelessly to realize remote control and local data update. [0003] At present, the shells of most smart home appliances are made of aluminum alloy, and then metal polishing, sandblasting, and oxidation are performed on the surface of the aluminum alloy material to improve the brightness of the shell. [0004] However, at present, the production cost of this surface treatment method is high, and the material cost of the aluminum alloy shell is also high, and the metal material...
