3C electronic product shell and manufacturing method thereof

Abstract

The invention discloses a 3C electronic product shell and a manufacturing method thereof. The 3C electronic product shell comprises a metallic structure, an antenna slot penetrates through the back and the front of the metallic structure, the antenna slot comprises a slot cavity and an antenna cutting position slit penetrating through the front of the metallic structure from the slot cavity, the antenna cutting position slit is filled with a nonconductive matter, an integrally inject-molded plastic structure layer is arranged on the back of the metallic structure, and the slot cavity is filled with at least part of the plastic structure layer. The 3C electronic product shell is favorable for completely solving the problem that the antenna cutting position on the surface of the electronic product metal shell is exposed, so that the electronic product metal shell is coherent in overall appearance and strong in metallic texture; and the 3C electronic product shell is simple in manufacturing process, low in cost and suitable for large-scale production, meets the requirement of 3C electronic product structures for appearance quality, and simultaneously has the advantages of easiness in manufacturing, low cost and practicability.

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
