Embodiment Construction

[0032] Please refer to Figure 1 to Figure 3 As shown, it shows the specific structure of the embodiment of the present invention.

[0033] A transparent crystal case, comprising a PC case base 10, the outer surface of the PC case base 10 is sequentially provided with a binder coating 20, a highly transparent silica gel layer 30, and a highly transparent hand feeling ink layer 40 from the inside to the outside, wherein , the high-permeable silicone layer 30 is molded and fixed on the outside of the PC shell base 10, and the high-permeable silicone layer 30 and the PC shell base 10 are combined and fixed through the adhesive coating 20; the high-permeable hand-feeling ink layer 40 is Spray on the outer surface of the high permeability silicone layer 30.

[0034] Further, in this embodiment, the CNC on the PC shell base 10 has a secondary injection hole, and a non-transparent colored injection part 50 is fixed by injection molding at the secondary injection hole, and the non-tr...

Abstract

The invention discloses a transparent crystal shell and a manufacturing process thereof. The transparent crystal shell comprises the following steps: (1) performing primary injection molding to obtaina PC shell matrix; (2) performing CNC (Computer Numerical Control) processing on the PC shell matrix so as to obtain a secondary injection molding hole; (3) fixing a non-transparent tape color injection molding part at the secondary injection molding hole by virtue of injection molding, and connecting the non-transparent tape color injection molding part and the PC shell matrix into a whole; (4)coating a binder to an outer side face of the PC shell matrix; (5) performing silicone liquid forming on one side, which is coated with the binder, of the PC shell matrix so as to obtain a high-transmittance silicone layer, and fixedly binding the high-transmittance silicone layer and the PC shell matrix by virtue of the binder coating; and (6) spraying a high-transparency hand feel ink layer on the outer surface of the high-transmittance silicone layer. Therefore, the high transmittance of the transparent crystal shell is improved. Meanwhile, the transparent crystal shell has excellent contact hand feel. Moreover, the transparent crystal shell has hardness and toughness and is difficultly scraped and damaged; and the manufacturing process is excellent in stability, excellent in controllability and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technology in the field of manufacturing electronic product casings, in particular to a transparent crystal casing and a manufacturing process thereof. Background technique [0002] At present, on electronic products such as mobile phones, transparent casings are used, which are mainly used as protective casings on the rear side of mobile phones; in the prior art, the light transmittance of transparent casings is not ideal, resulting in poor Presents the appearance of the mobile phone. In addition, the existing transparent casing has disadvantages such as poor handling and poor durability. [0003] Therefore, in the present invention, the applicant carefully researched a new technical solution to obtain a transparent crystal shell, the light transmittance of which is greatly improved, and at the same time, it feels better in use and is durable. Contents of the invention [0004] In view of this, the present invention ai...
