A curved shell and its forming process

Abstract

The invention provides a curved-surface casing, comprising a casing body that is of curved surface; the casing body comprises a base layer and a connection layer; the base layer is of curved surface; a first layer of pattern is arranged in the base layer; the base layer is mounted at the surface of an object to be mounted through the connection layer. The invention also provides a forming process of the curved-surface shell. The forming process of the curved-surface casing provides glass relief appearance with multilayer pattern decoration, stereoscopic impression and fashion, and good attraction and high grade; the casing has high surface hardness, good integral strength and good structural stability, meets customizing needs, is detachable and is waterproof and crashproof. The cured-surface casing is ingenious in structure and technically reasonable, and has good market application prospect and commercial value.

Description

technical field [0001] The invention relates to shell preparation, in particular to a curved shell and a molding process thereof. Background technique [0002] Glass relief products are rich in color, clear in layers, three-dimensional fashion, beautiful and high-grade, and the visual effect is dazzling, and are highly sought after by people. Only rough and simple relief patterns can be produced, and the glass carving process is complex, with many manual processes and the quality mainly depends on techniques and experience, and the production cost is high. It is generally only used in the glass art industry. It belongs to the handicraft production process and is difficult to mass-produce manufacturing. At the same time, with the continuous improvement of high-value-added wearable devices, mobile phones, smart watches, mobile electronics and other portable 3C mobile electronics products, as well as fierce market competition, more and more glass materials are used for the len...

AI Technical Summary

Problems solved by technology

However, traditional electronic product lenses will reserve assembly gaps due to multi-component assembly during assembly. At the same time, the foam sticking process is used, resulting in a large space for the assembly structure and manual operation by professional maintenance personnel. The stability is difficult to guarantee. Compared with current electronic products The development trends of thinness, fashion, and practicality are contrary to each other, and it is difficult to meet the development needs of mobile electronics

[0003] Due to the limitations of traditional manufacturing processes, glass structural parts such as glass screens, panels, and back covers are all glued or pasted on plastic or metal shells. Once the glass structure is damaged, it is very difficult to repair the overall structure.

Even if it is operated by professional maintenance personnel, it often needs to be replaced together with the assembly structural parts attached to it, which brings great difficulties to after-sales and maintenance of the product

For high-end electronic products, while using glass materials to enhance the fashion and novelty of the appearance, because the glass structural parts of the traditional pasting process are pasted with glue or back glue, it cannot meet the demands of high-end customers for customized fashionable detachable structures; traditional The glass structure needs to be pasted on other structural parts during assembly. At the same time, it has no waterproof function. It needs other structural parts to achieve the waterproof effect, and the thickness of the product increases, which increases the overall process and cost. Traditional PMMA, PC, etc. are transparent Because the surface hardness of plastic is generally lower than 2H, it is difficult to overcome the damage caused by scratches caused by hard objects in daily use

Although some users use surface film for secondary protection on the lenses and back covers of commonly used electronic products, there are still scratches on the surface, which affects the user experience

There are also electronic product glass lenses that use sapphire material (hardness as high as 7H), which is second only to diamond in hardness. Although it can effectively prevent hard objects from scratching and effectively protect electronic product lenses, it has poor toughness and is fragile due to high hardness. The characteristics of drop resistance, the lens is often damaged and cracked due to pressure in daily life

In particular, the popular 3D curved glass has weak drop resistance after bending, and is more likely to be damaged due to bumping and falling.
