Problems solved by technology

Since the printed pattern or letter is higher than the surface of the paint layer, the pattern or letter is easy to be worn or even peeled off during use, thus affecting the appearance of the product
[0003] In order to avoid this problem, people again print a transparent ink on the pattern or letter to avoid the pattern or letter from being worn, but the transparent ink is also higher than the surface of the paint layer on the one hand, and does not have strong wear resistance On the other hand, printing transparent ink makes the edge of the line forming the pattern or letter halo, and also affects the appearance of the printed pattern or letter

Embodiment Construction

[0015] see figure 1 As shown, the casing 10 of the preferred embodiment of the present invention includes a transparent base 11 , a decoration layer 13 formed on the transparent base 11 and a transparent protective layer 15 formed on the decoration layer 13 .

[0016] The transparent base 11 is a plastic layer, which can be made by injection molding. The material forming the transparent substrate 11 can be selected from polyethylene (PE), polyamide (PA), polycarbonate (PC), acrylonitrile-styrene-butadiene copolymer (ABS), polymethacrylate Either polyester (PMMA) or polyethylene terephthalate (PET) plastics. The surface of the transparent substrate 11 that is not combined with the decoration layer 13 is provided with a colored ink 17 , and the colored ink 17 can be printed on a part of the surface of the transparent substrate 11 . The color of the colored ink 17 can be selected according to the needs of the product.

[0017] The decoration layer 13 is a colored paint layer, ...

Abstract

The invention relates to a shell which comprises a transparent substrate, a decoration layer formed on the transparent substrate and a transparent protection layer formed on the decoration layer, wherein hollowed-out patterns are formed on the decoration layer, and color ink is printed on the surface of the substrate, which is opposite to the decoration layer. A method for manufacturing the shellcomprises the following steps: providing the transparent substrate; arranging the decoration layer on the surface of the transparent substrate; arranging the transparent protection layer on the decoration layer; forming the hollowed-out patterns on the decoration layer; and printing color ink on the surface of the transparent substrate, which is opposite to the decoration layer.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a pattern or a trademark that is not easy to fall off and a manufacturing method thereof. Background technique [0002] The existing plastic casings of portable electronic devices such as mobile phones, digital cameras, personal digital assistants, and notebook computers are usually sprayed with a decorative paint layer, and then printed patterns or letters are used as trademarks of the product on the paint layer. Since the printed pattern or letter is higher than the surface of the paint layer, the pattern or letter is easily worn or even peeled off during use, thereby affecting the appearance of the product. [0003] In order to avoid this problem, people again print a transparent ink on the pattern or letter to avoid the pattern or letter from being worn, but the transparent ink is also higher than the surface of the paint layer on the one hand, and ...
