Method for processing three-dimensional metal bead

Abstract

A processing method of a tridimensional metal water droplet comprises first, cleaning the surface of a plastic component by ultrasonic, second, spraying a UV paint layer, and then UV solidifying, third, covering a spraying utensil whose central portion is hollowed out to be a plurality of water droplet shape on the UV paint layer, spraying a UV paint layer, and UV solidifying, and obtaining a plurality of water droplet-shaped granule on the surface of the plastic component, fourth, sputtering a layer of metal film, fifth, spraying a UV light oil layer again, UV solidifying again, and then forming a protecting film. The method of the invention combines the technology of spraying and reactive sputtering, the external visual effect of the qualitative sense of tridimensional metal water droplet can be obtained on the plastic outer casing of electronic products, and the method can be applied to various decorative coating films and have wide application range.

Description

【Technical field】 [0001] The invention relates to a process for forming a raised metal texture, in particular to a processing technology for forming three-dimensional metal drops on a plastic part. 【Background technique】 [0002] Nowadays, the functions and performances of various electronic products tend to be the same. Therefore, in order to expand market share, all manufacturers have made great efforts in the appearance of electronic products. Among them, in order to obtain a metallic texture and a good touch in appearance, all manufacturers will use plastic materials. A layer of metal film is formed on the shell by vacuum sputtering. Although this method gives it a metallic texture, the appearance of the product still tends to be consistent under mass production, so I thought of making a three-dimensional water drop visual effect on the plastic shell. [0003] Thus, it is thought of using ultraviolet curable paint, that is, the immiscible characteristics of UV paint to f...
