Abstract

The invention provides a housing assembly, a making method thereof and an electronic device. The housing assembly comprises a substrate, a pattern layer, a barrier layer and a dip dyeing layer, wherein the pattern layer is arranged on the first surface of the substrate; the barrier layer is arranged on the surface, far away from the substrate, of the pattern layer and covers the exposed first surface; and the dip dyeing layer is arranged on the surface, far away from the substrate, of the barrier layer. Thus, through arranging the barrier layer between the pattern layer and the dip dyeing layer, dye molecules can be effectively prevented from impregnating into the pattern layer and the substrate during dip dyeing, and in a subsequent finished product state, the dye molecules can be prevented from impregnating into the pattern layer and the substrate for a long time, the gloss of the pattern layer and the strength of the substrate can be effectively ensured for a long time, and the pattern layer is ensured not to generate orange peel and fall; the thickness of the dip dyeing layer does not need to be increased, the dyeing uniformity of the dip dyeing layer is further effectively ensured, and the problem that the dip dyeing layer is likely to crack can be effectively prevented; and besides, bad phenomena of a noise point appearing on the dip dyeing layer do not happen.

Description

technical field

[0001] The present application relates to the technical field of electronic equipment, and in particular, relates to a casing assembly, a manufacturing method thereof, and electronic equipment. Background technique

[0002] With people's continuous exploration and pursuit of beauty, the conventional monochromatic and matte effects have gradually become aesthetically fatigued, and the gradient of colorful colors has gradually become a trend. In order to realize the gradient on the mobile phone casing, the main methods currently include gradient spraying, dip-dyeing, offset printing, and ribbon thermal transfer printing. However, the color gradient casings prepared by the above methods have defects, which seriously affect the appearance of the casing.

[0003] Therefore, further research is needed on the housing components. Contents of the invention

[0004] This application aims to solve one of the technical problems in the related art at least to a certain...
