Embodiment Construction

[0013] The casing 10 of the preferred embodiment of the present invention is as figure 1 As shown, it includes a substrate 11 , a powder coating 13 formed on the substrate 11 and a pattern layer 15 formed in the powder coating 13 .

[0014] The base 11 is a metal base, and the material for making the base 11 can be aluminum or aluminum alloy, magnesium or magnesium alloy, titanium or titanium alloy, and the like.

[0015] The powder coating 13 is formed by spraying on a surface of the substrate 11 by means of electrostatic powder spraying. The paint forming the powder coating 13 can be polyurethane resin powder or epoxy resin powder. The thickness of the powder coating 13 is between 60-90 μm. Grooves are formed on the powder coating 13, and the grooves can be formed by laser etching. The texture of the groove is set as a product's trademark or other decorative patterns, and the depth of the groove can be equivalent to the thickness of the powder coating 13 .

Abstract

The invention relates to a shell which comprises a basal body, a powder coating and a pattern layer, wherein the powder coating is formed on the basal body, the pattern layer is formed in the powder coating, a groove is formed on the coating, and the pattern layer is sol filled in the groove. A manufacturing method of the shell comprises the following steps: providing the basal body; spraying thepowder coating on the surface of the basal body; etching the groove on the powder coating; and filling sol in the groove.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof. Background technique [0002] A decorative coating or a protective coating is usually sprayed on the metal shell of the existing portable electronic product to improve the decorative or usable performance of the product. Commonly used methods for forming coatings on metal casings include liquid paint spraying or solid powder paint spraying. Solid powder spraying is widely used due to its advantages of high paint recycling rate and environmental protection in the spraying process. At present, when making a product's trademark or logo pattern on the powder coating of the metal shell, it is usually the way of printing ink. The trademark or iconic pattern formed by this printing is usually thin and has no three-dimensional effect, and its bonding force with the powder coating is low, so it is easy to be worn during use, thereby affecting the appearance of the product.
