Abstract

The invention discloses a spraying process for mobile phone shells. The spraying process includes steps of a, loading shells which are subjected to injection molding by the aid of molds, and carryingout polishing treatment on defective products; b, carrying out electrostatic dust removal on the surfaces of products, then blowing and sweeping the surfaces of the products and carrying out electrostatic dust removal again; c, coating primer paint, to be more specific, carrying out primer paint spraying treatment on the products in spraying rooms by the aid of spraying guns, then drying the products and carrying out illumination treatment; d, coating UV (ultraviolet) finish paint, and to be more specific, carrying out UV paint spraying treatment on the products coated with the primer paint bythe aid of the spraying guns; e, carrying out leveling treatment on the products with the sprayed UV paint by the aid of conveyor lines; f, carrying out UV curing, and to be more specific, carrying out ultraviolet radiation on the mobile phone shells by the aid of UV lamps after the leveling treatment is carried out on the mobile phone shells; g, cooling the cured mobile phone shells by means ofelectrostatic air blast; h, carrying out inspection and warehousing. The spraying process has the advantages that the problems of color fading and color difference can be effectively solved by the aidof the mobile phone shells produced by the aid of the spraying process; the production efficiency can be improved, the production cost can be reduced, and environmental pollution can be abated.

Description

technical field [0001] The invention relates to the field of painting technology, in particular to a mobile phone shell spraying technology. Background technique [0002] With the continuous progress of society and the continuous development of science and technology, the quality of people's life is also rising. In daily life, portable electronic products are also one of people's necessities. In order to improve their aesthetics and texture, the shells of these electronic products are therefore Coating is required on non-metallic housings. However, the cost of the mobile phone case produced by the existing coating process is relatively high, and it is easy to change color, which affects the appearance of the product. Contents of the invention [0003] In view of the above deficiencies, the object of the present invention is to provide a mobile phone shell spraying process, the mobile phone shell produced by the spraying process can effectively solve the problems of its fa...
