preparation example Construction

[0018] According to the preparation method provided by the present invention, in order to make the surface of the electronic product smooth, preferably, the method further includes performing surface treatment on the electronic product after injection molding. The surface treatment includes removing peripheral burrs by grinding, polishing the surface of the product, so that the quality of the surface of the amorphous material matrix and the surface of the ceramic pattern tend to be consistent.

[0019] According to the preparation method provided by the present invention, preferably, the ceramic pattern is prepared by mixing paraffin wax, polyoxymethylene, zirconia powder and binder, followed by extrusion, injection molding, degreasing, extraction and sintering.

[0020] The mixing means that according to the requirements of the product design loss on ignition rate, the raw material powder and the binder are configured according to a certain ratio, and then uniformly mixed in a...

Abstract

The invention provides an electronic product outer shell which comprises an amorphous substrate and ceramic patterns embedded in the substrate. The invention further provides a manufacturing method for the electronic product outer shell. According to the electronic product outer shell, the ceramic patterns are embedded in a specified portion in amorphous materials, the function of decoration is performed, and the shielding of signals by the outer shell made of the amorphous materials can be further improved. Further, due to the fact that ceramic is a high-end decorative product and is brittle and fragile, the ceramic is mixed with the amorphous materials, the advantages of both the ceramic and the amorphous materials can be achieved, and additional value of the overall product is improved.

Description

technical field [0001] The invention belongs to the field of electronic products, in particular to an electronic product casing and a preparation method thereof. Background technique [0002] Amorphous material is a high-strength, high-elasticity, wear-resistant, corrosion-resistant, high-quality, isotropic alloy. One-time molding of parts can provide engineers with better design freedom and make it possible for parts to be miniaturized and multi-functional. [0003] At present, most of the applications of amorphous materials are concentrated on wearable parts such as rotating shafts and slide rails. Since the products of amorphous materials have the advantages of high strength and light weight, their application in electronic product casings will tend to increase. However, due to the disordered arrangement of atoms in the product of amorphous materials, it has a greater shielding effect on radio frequency signals and will affect the signals of electronic products.
