preparation example Construction

[0053] The present invention also provides a method for preparing a metal shell with a ceramic panel, wherein the method includes the following steps:

[0054] (1) placing the ceramic panel and the metal frame into the injection mold, and making a certain gap between the surroundings of the ceramic panel and the metal frame;

[0055] (2) The plastic layer is formed by injection molding a resin composition.

[0056] According to the present invention, in step (1), by placing the ceramic panel and the metal frame into the injection mold, keeping a gap of uniform size between the two and keeping the upper surfaces of the two flush in the mold, and then through the step ( 2) Injection molding to form the plastic layer.

[0057] According to the present invention, the material of the ceramic panel can be conventionally selected ceramics in the field, preferably one or more of zirconia, alumina and silicon oxide. These ceramic panels can be obtained commercially, for example, zirc...

Embodiment 1

[0090] This embodiment is used to illustrate the metal shell with ceramic panels and the preparation method thereof provided by the present invention.

[0091] 1) The metal frame is obtained by CNC machining. The length of the metal frame is 127mm, the width is 65mm, and the thickness is 8.2mm. The material of the metal frame is aluminum alloy, and the thickness of the metal material is 1.5mm;

Abstract

The invention relates to a shell and a preparation method and application thereof and discloses a metal shell with a ceramic panel and a preparation method thereof, and application of the metal shell as a communication device case. The metal shell comprises a ceramic panel, a metal frame, and a plastic layer; the periphery of the plastic layer is in contact with at least one part of the inner side of the metal frame; and the plastic layer has a recessed part and the ceramic panel covers the recessed part and is in contact with the plastic layer. Therefore, the metal shell has a flat appearance, high strength, and good anti-impact performance.

Description

technical field [0001] The present invention relates to a housing and its preparation method and application, in particular to a metal housing with a ceramic panel, its preparation method and the application of the housing as a communication device housing. Background technique [0002] In the current production process of the communication equipment casing, the panel and the lower display part are generally bonded with glue, and then connected to the metal casing through a buckle structure provided on the display part. This connection through assembly, due to the different dimensional processing accuracy of each component during the processing process, there is a certain processing error between the panel and the metal shell, resulting in a large gap or step between the two after assembly. Seriously affect the appearance of the product, and reduce the strength and impact resistance of the shell. Contents of the invention [0003] The first object of the present invention...
