PTING Intelligent Sandblasting Machine——Application of AG Glass Sandblasting Process

Not long ago, at the new product launch conference of the new iPhone series, the back cover of the mobile phone has adopted a new generation of ceramic bead sandblasting AG glass technology, which is delicate and warm in hand, and has a fine, soft and comfortable feeling when touched. , and there is also the advantage that the glass material is not easy to be stained with fingerprints. With the advent of the 5G era, people have higher and higher requirements for the visual experience and aesthetics of mobile phones, and the development of ceramic bead blasting AG glass technology has promoted the back cover of mobile phones from traditional metal, plastic and other materials to AG glass. develop.

When it comes to the frosted glass made by AG technology, everyone should be familiar with it. At present, Apple, Huawei, OPPO, OnePlus, etc. are all using it in the flagship phones of high-end mobile phone brands. On the recently released iPhone 11 Pro series, Apple made the glass on the back of the fuselage into a frosted texture through AG technology, which brought a better hand experience.

AG glass (Anti-Glareglass) is anti-glare glass, which refers to the special treatment of the glass surface by corrosion, coating, sandblasting or polishing, etc., to change the roughness of the glass surface, so that the surface has a matte effect, achieving The effect of diffuse reflection.

The AG implementation method of the early mobile phone glass cover was mainly chemical etching, such as Huawei's Mate20, OPPOR17pro, OnePlus 6, etc. However, the cost of chemical etching is relatively high, and relatively speaking, it has a great impact on the environment. It is understood that the glass shell of the new model released by Apple on September 11 uses a new generation of technology developed in cooperation with the processing manufacturer-ceramic bead sandblasting (not the AG etching mentioned earlier), and the glass back cover of the iPhone 11pro series is also Switched from a glossy finish to a custom matte texture.

Sandblasting

Sandblasting is a process in which the sand-water mixture is used as the medium, and the pressure generated by the sandblasting machine is sprayed on the surface of the glass to polish it. As early as 2018, an Apple patent called Surface Finishing was exposed, which showed that Apple was developing a new iPhone body processing technology.

The patent details the process of creating textured grooves in the fuselage by sandblasting, though Apple uses ceramic beads instead of conventional sandblasting.

Sandblasting process through the impact of the sand sprayed by the sandblasting machine on the surface of the workpiece, so that the surface of the workpiece can obtain a certain degree of smoothness and different roughness and particle size, and at the same time improve the mechanical properties of the surface of the workpiece, thus improving the soothing effect. Tiredness, also increases the adhesion between the coating and prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating, removes impurities, variegated colors and oxide layers on the surface, and at the same time roughens the surface of the medium , to make the substrate surface residual stress and improve the surface hardness of the substrate. At present, many domestic companies have mature technology and equipment, which have been used in many well-known brand mobile phones.

The advantages of sandblasting are:

The technological process is simplified, the production efficiency is high, and it is more environmentally friendly. The use of sandblasting is wider, and it can also be used on ceramic covers. It is understood that Apple's new generation of Applewatch also uses sandblasting. With the release of Apple iPhonepro matte AG glass, the new generation of AG glass is sandblasting Processing may become the mainstream process for the surface treatment of 5G mobile phone casings in the future.

With the advancement of technology, AG etching has become the mainstream process of glass surface treatment, which can not only reduce the impact of reflection, anti-glare, anti-blue light, but also be applied to the texture design of the glass surface.
