A kind of 3C electronic product shell and preparation method thereof

Abstract

The invention discloses a 3C electronic product casing and a preparation method thereof. The electronic product casing includes a metal structural part, and a plurality of micro-slits for antenna slits are formed between the back and the front of the metal structural part. The antenna slits are filled with non-conductive pre-injection materials, and the back of the metal structure has a secondary injection-molded plastic structure, and the plastic structure is combined with the pre-injection material and the metal structure as one. The invention can completely eliminate the problem of exposure of the cut position of the antenna on the surface of the metal shell of the electronic product, realize the complete and coherent appearance of the metal shell of the electronic product, strong metal texture, and simple manufacturing process.

Description

technical field [0001] The invention relates to a 3C electronic product casing and a preparation method thereof. Background technique [0002] With the development needs of 3C (Computer, Communication, Consumer Electronics, computer, communication and consumer electronics) electronic products for miniaturization, thinning, fashion and practicality, more and more shells of existing electronic products are made of light weight and High-strength metal materials, such as aluminum alloy, stainless steel, titanium alloy, etc., to meet the needs of thinner and thinner products, higher and higher strength of the whole machine, light weight, outstanding texture and fast heat dissipation. [0003] Although the use of metal materials can improve the strength and texture of the electronic product shell, due to the shielding of the antenna signal of the communication electronic product, it is necessary to process the antenna on the metal part and use plastic connection to solve the signa...

AI Technical Summary

Problems solved by technology

[0003] Although the use of metal materials can improve the strength and texture of the electronic product shell, due to the shielding of the antenna signal of the communication electronic product, it is necessary to process the antenna on the metal part and use plastic connection to solve the signal problem of the communication electronic product. Structural parts Cannot maintain a complete and coherent appearance

[0004] At the same time, due to the limitations of traditional processing methods, equipment, materials and costs, the width of the cutting position of the metal shell antenna of communication electronic products is more than 1.2mm, so that the filled plastic material leaks out on the appearance of the metal shell, and consumers can It is obvious that there is a significant difference in feel from metal materials, which greatly reduces the metal texture of the shell and the experience effect of consumers. It cannot satisfy the high-end and fashionable appearance effect but is difficult to eliminate
