with the popularity of smartphones, many mobile phone accessories manufacturers have ushered in new market opportunities. "Mobile phone tempered glass membrane" a familiar and unfamiliar product is also accompanied by the arrival of the era of smart phones to live .
in this industry background, a can replace the traditional mobile phone pet film products "mobile phone tempered Glass film" (hereinafter referred to as tempered film) quietly came to China, and constantly by the industry's heat. At the same time, as the production process of tempered film and mobile phone cover plate process very similar, the previous process is basically the same. Thus, many manufacturers of mobile phone cover plate began to consider the transformation to do tempered film, at the same time as the product as a new thing just listed soon, there are a lot of new manufacturers to add to the tempering film production industry. from now on, the market of tempered film has just slowly heat up. In our daily life, but also gradually become a kind of mobile phone necessary accessories, appear in the major mobile phone accessories market.
Hand Machine tempered film production process: 1. Glass Material:first, manufacturers will buy from the supplier mobile phone big raw thin glass to open material. (Large glass size specifications are: 1100*900,480*380, etc.); the thickness of the glass is currently on the market in the following several thicknesses (in MM). 0.4mm,0.33mm,0.20mm,0.15mm and so on. According to recent market observation, 0.33,0.2 thickness of tempered film in the market is relatively popular. 2.CNC Machiningthrough the first open material process into a rectangular small size glass, and then through the CNC engraving machine according to the shape and size of different mobile phone models processing, processing into a prototype tempered film, with the shape of the tempered film finished product. 3. Sweeping or flat grindingCNC machining, due to the operation of the process or other reasons, as well as the market for tempered film edge radian requirements, the flat grinding and sweep process processing, through this process can effectively remove the steel film surface scratches and increase the edge of the tempered film radian and brightness, in order to achieve beautiful and durable function. 4. Temperingafter sweeping or flat grinding, in order to increase the stress value of tempered film and increase the toughness of tempered film, the process of finishing semi-finished products on the upper road is tempered. In general, the semi-finished products are placed to 420 degrees of acid potassium in the liquid for 3-4 hours of tempering, through tempered film glass na ions and K ions fully exchanged to make on the surface of the tempered film stress layer, so as to achieve the effect of bending and anti-impact, in order to protect the role of mobile phone screen. 5. Oil-coatedin order to prevent the tempered film is contaminated, now the industry to produce tempered film coating oil treatment. The general coating is anti-fingerprint oil to achieve anti-oil effect. Oil painting process Now there are three kinds of ways: A: Hand coating, B: Spraying, C: electroplating. Its processing effect is more and more in turn. Of course, the related processing costs will increase. 6. LaminationThis process is also the most important process in the production of tempered film. The so-called lamination is in the first few process processing of semi-finished steel film surface lamination on a special glue to achieve the perfect film can be affixed to the mobile phone touch screen, so that it does not appear bubbles, look beautiful increase the luminosity. The gum in the market is commonly known as (ab Gum), the current market is mainly: Japan's Toyo, Nippa, and so on; 7. Packagingafter the processing of the above several process products by the quality of inspection after the last step into the final process-packaging. Due to the different manufacturers, the packaging is not the same. I'm not in the one by one narrative here. The above is what I know, for the production of tempered film A brief overview, if there is improper place also please a lot of understanding. I sincerely look forward to working with interested friends to discuss the development of the industry, as well as tempered film products related topics.
