What is the impact of the 3D glass era on CNC processing?
Cell phone shells from plastic transition to metal, cell phone plastic shell manufacturers can not receive a single, large-scale closure or transformation (see: Cell phone metal + plastic shell manufacturer why can not receive a single?); from the second half of last year, CNC processing local saturation, some cell phone metal shell processing plant also began to receive a single, the phenomenon of selling second-hand CNC machines (see: for a rainy day, cell phone metal + plastic shell manufacturers can not receive a single?). Now, cell phone shells from metal to glass gradually shift; if you are still at a loss, please look at this article; it may be helpful!
The 5G era has been fully developed; the metal shell is born to signal to shield, is no longer enough to meet the new design requirements, consumer aesthetic fatigue for the metal shell gradually began, and a revolution around the replacement of the metal shell of the phone has begun.
What is the impact of the 3D glass era on CNC processing?
1. metal processing volume increase in the frame: 3D glass shell cell phone metal strength requirements are high, 6,7 series aluminum alloy can barely meet, but more will tend to stainless steel, stainless steel processing difficulties, person-hours will increase.
2. CNC processing graphite mold volume increase: 3D glass double curved screen, using CNC processing is very uneconomical, long working hours, low efficiency, the current basic is the use of heat bending machine, heat bending process to replace a large part of CNC processing, and glass heat bending requires more graphite furnace mold, so part of the CNC capacity will be shifted from the processing of metal to graphite mold processing.
3. CNC processing of metal to the grinding edge of glass: to fit the screen to the phone, 3D glass requires a finishing grinding edge, so part of CNC will shift to the grinding edge of the glass.
As early as 2013, nano-injection molding cell phone metal shell was first brought to the market by HTC cell phones; after three years of development, it has become the standard for the vast majority of flagship cell phones, all-metal unibody molding is often a major cell phone propaganda magic. Metal shell because it can provide high strength; thus, the phone can be made very thin (about 5mm), and the appearance of good texture, good heat dissipation, manufacturing process diversification, highly recognized by the market, get fast development! However, since the release of the iPhone 7, the metal body design has ended, and it isn’t easy to innovate! The 3D glass will most likely replace this dominant position; why?
Metal shell, due to their electromagnetic shielding role, in the 4G era, had to be isolated with PPS, PBT, and other plastic multi-segment; with the development of mobile communication technology, we have now stepped into the 5G era and has been a comprehensive development of the industry chain, 5G communication signal more complex. NFC, wifi, and wireless charging technology will now be the standard for cell phones, glass material, and other non-electromagnetic shielding materials, ushering in a major opportunity.
What is 3D glass?
The glass cover used in digital products is divided into 2D glass, 2.5D glass, and 3D glass. 2D glass is ordinary pure flat glass, without any curved design; 2.5D glass is flat in the middle, but the edge is curved design; and 3D screen, both the middle and the edge are curved design, 3D glass is the 2D glass through CNC or heats bending molding to get; CNC processing is time-consuming, the yield is long. CNC processing is time-consuming and low-yield, making it difficult to mass produce.
The low power consumption and bendable characteristics of the flexible OLED display is a revolutionary breakthrough for cell phones and wearable devices, and 3D glass can only fit the flexible screen, thus playing a physical protection role. Glass material is inexpensive, comfortable to the touch, is an excellent alternative material, and at the same time, to obtain a symmetrical aesthetic with the cover 3D glass, the back glass also to curved 3D, the market size to further expand.
Now in the cell phone terminal, Samsung, Samsung, Xiaomi, Xiaomi, VIVO, and other brands have adopted 3D glass covers or 3D glass back panels; Apple, Huawei, OPPO, and other cell phone host factory also launched their own high-end 3D glass cell phone; foundry, by Bern Optical, has long been mass production, Lance Technology, and other 3D curved glass production industry chain has developed mature, including Chunxing Precision, Victory Precision, etc. Manufacturers are also involved in the industry chain, etc.; raw materials, Corning launched the glass, which will be more suitable for manufacturing 3D glass; some domestic glass substrate suppliers also have production strength, and 3D glass is now a mainstream direction.
