3D hot bending glass processing is to put flat glass into a curved mold, then press it at a high temperature close to the softening point of the glass, which is about 800 degrees Celsius, and take it out after a period of time, so that curved glass is obtained. As 3D curved glass is becoming more and more familiar to people, the market's acceptance of 3D glass is also getting higher and higher, and mobile phone material manufacturers are also stepping up research on the mass production and processing of 3D glass. Today we will introduce the production process of 3D hot bending glass processing, hoping to help you in the production process of 3D hot bending glass processing.
3D hot-bent glass processing production process: Project: confirm whether the customer's drawings can be produced, make factory drawings and films, confirm the process, issue instructions, and track the entire sample line. Cutting: Material requirements: The glass material is 3D curved glass. When the flat glass enters the deep processing operation, a process is to increase the processing allowance according to the customer's drawing size requirements, and then input the data into the CNC cutting machine for blank production, commonly known as cutting. Profiling: Automatic CNC processing is used to obtain the final size required by the customer. In the deep processing of ultra-thin optical and electronic glass, CNC milling equipment is selected to profile the cut optical and electronic glass blank, remove most of the machining allowance, and control the size within the dimensional tolerance requirements. Thermal bending: heat treatment with stable curvature. The main difference between the 3D curved cover glass and the ordinary cover glass is the curved surface, which can meet the design freedom of various shapes and structures. According to the characteristics of glass thermal processing, the industry heats a good-sized cover glass to a softening point, and then deforms the glass along the curved surface of the mold to form the final 3D curved surface feature. Molding: Graphite material is an indispensable mold material in glass manufacturing in recent years, because it is chemically stable, not easily penetrated by molten glass, does not change the glass composition, has good thermal shock resistance, and has small size changes with temperature.
In the 3D hot bending glass processing process, not only must the physical properties of the glass material be sufficiently understood, but also a graphite mold with high processing quality and high precision. The glass material can be processed only after the glass material is heated to the softening point. A 3D curved cover glass meets the requirements.
3D hot bending glass processing should be controlled links: 1. Glass cutting size. Difficulty: Sometimes, the glass cutting machine cannot accurately cut the glass that conforms to the shape of the mold, resulting in a large dimensional tolerance range of the glass product, which directly affects the pass rate of the product, for example, the edge chipping rate of the glass will increase. Solution: The glass cutting machine is used, and the tolerance of the glass size and the mold after cutting is controlled within 0.01 mm. 2. Glass thickness. Glass materials of different thicknesses are an important part of adjusting the hot bending process parameters and have a very important impact on the yield of products.
Principle of AG glass: After "roughening" the glass surface, the reflective surface of the glass (flat mirror surface) becomes a non-reflective matt surface (a rough surface with unevenness).
Compared with ordinary glass, it has a lower reflectance. The reflectance of light is reduced from 8% to less than 1%. The technology creates a clear and transparent visual effect, allowing viewers to experience better sensory vision.
AR glass principle, using the most advanced magnetron sputtering coating technology in the world to coat a layer of anti-reflection film on the surface of ordinary strengthened glass, which effectively reduces the reflection of the glass itself, increases the transmittance of the glass, and makes the original transparent The colors of the pasted glass are more vivid and real.
Two, the use environment is different
AG glass use environment:
1. Strong light environment. If there is strong light or direct light in the environment where the product is used, such as outdoors, it is recommended to use AG glass, because the reflective surface of the glass becomes a matte diffuse reflective surface due to the AG processing, which can make the reflective effect blur. In addition to preventing glare, it also reduces reflectance and reduces light and shadow.
2. Harsh environment, in some special environments, such as hospitals, food processing, exposure to the sun, chemical plants, military industry, navigation and other fields, the glass cover must not be peeled off.
3. Contact with touch environment, such as plasma TV, PTV rear projection TV, DLP TV splicing wall, touch screen, TV splicing wall, flat panel TV, rear projection TV, LCD industrial instrumentation, mobile phone and advanced photo frame and other fields.
AR glass use environment:
The high-definition display environment, such as the use of products, requires high-definition, rich colors, clear levels, and eye-catching; for example, if you want to watch high-definition 4K when watching TV, the picture quality must be clear, the colors must be dynamic, and reduce color loss or color difference.. ....
Places within sight such as museum showcases and displays, telescopes in the field of optical instruments, digital cameras, medical equipment and equipment, machine vision including image processing, optical imaging, sensors, analog and digital video screen technology, computer technology, etc., and Exhibition glass, watches, etc.
3. Different in nature
AG glass (English name: anti-glare glass abbreviation), also known as anti-reflective glass and anti-glare glass, is used to "reduce glare reflection or direct light."
AR glass (English name: anti-reflection glass abbreviation), also called anti-reflection glass, is used to "reduce reflection and increase transmission".
Engineering-cutting-slotting-chamfering-fine carving-flat grinding-cleaning-electroplating / screen printing-lens cleaning-packaging.
The entire production and processing are carried out in a dust-free workshop, which requires high production environment, and the selected mobile phone glass cleaner needs to be more high-quality, more professional, and more stable.
Engineering: Confirm whether the customer's drawings can be produced, make factory drawings and film, and confirm the process. (The drawing film needs to have the production date and number. If there is any modification, update it in time, and take back the old drawing and film), issue an instruction sheet, and track samples across the board.
Cutting: Open the glass to 15-20 C larger than the product, enter a single tank ultrasonic cleaning, and then transfer to the next production process, and process the opened material into a shape consistent with the drawing provided by the customer , If you choose the Hengyuan CNC glass engraving machine with high precision, fast speed and stable performance, many products can not use the car side link, and it can bring you more precise dimensions.
Slotting: Slotting products that require slots is completed by a stable and accurate Hengyuan CNC engraving machine.
Chamfering: The finished product of the car side is edged to meet the requirements of appearance and performance according to customer requirements. The chamfering does not require a single beveling machine. The grinding wheel grinding head is designed and processed by the engineer to achieve straight edge beveling. Get it all at once.
Carving: It mainly processes glass products that cannot be achieved by ordinary processes such as perforating and stepping. It can also replace the processes of car edging, slotting, and chamfering. However, the sales price of engraving machines is not cheap, and many manufacturers still make them according to traditional crafts; but you can carefully and cost-effectively. After saving the first three crafts, how much can you reduce your expenses? (Equipment, manpower, electricity cost, floor space) and also make you more sophisticated products; after CNC precision carving is completed, it must be cleaned by single-slot ultrasonic cleaning, and then flat grinding.
Flat grinding: The surface finish of the finished product is required to control the thickness of the glass. This link is indispensable, and good quality flat grinding equipment should be selected.
Cleaning: After cleaning the finished products of the flat grinding process, strengthen the treatment to improve the surface hardness and impact resistance of the glass, so as to meet the customer's requirements; before tempering, it must be ground grinding for a few minutes after tempering, and then ultrasonic Clean, in the ultrasonic cleaning process, you need to pay attention to choosing a good optical glass cleaning agent, enter the electroplating or screen printing process; the glass lens that needs to be tempered must be scratched or chipped before being tempered.
Electroplating/silk printing: the flat-grinding white film products are processed by electroplating or silk printing to achieve the required effect of the lens.
Cover plate cleaning: Put the screen-printed or electroplated deplated lens into ultrasonic and add a cleaning agent to clean it. The effect after cleaning is that no scratches, watermarks, white spots, fingerprints, grinding powder, dust remain on it. , The effect of the dust-free workshop will not occur, and it must be handled well. Many manufacturers often have a lot of problems in this process, and it is difficult to solve them. The main reason is often the problem of the optical glass cleaner you use. The high-quality optical glass cleaner scratches, watermarks, white spots, and fingerprints. , Grinding, and choosing a good cleaning agent is also a very important thing.
Packaging: Clean, inspect, and package products that have been processed and meet customer requirements. When packaging, use a low-viscosity protective film to package, and there should be no bubbles when laminating.
Since the launch of Nokia N9 in 2011, a term about mobile phone screens has gradually become familiar to people, which is "glass panel". The biggest difference between a glass panel and ordinary glass is that although the front of this glass is flat, the edge part is recessed into an arc.
After Apple iPhone 6 and Samsung Note 4 followed suit in 2014, manufacturers have used 2.5D glass in their flagship products. The same is 2.5D glass, but the level in the industry is uneven, and the effects shown by Xiaomi Note and nubia Z9 are also very different. Because when 2.5D glass is matched with other materials, how to achieve a smooth transition becomes the biggest test. It can be said that how to make good use of 2.5D glass has become a challenge for mobile phone manufacturers' industrial design and quality control capabilities, and has also become a touchstone for torturing mobile phone manufacturers' product attitudes.
2.5D Glass Eight Immortals Crossing the Sea
When mobile phone manufacturers use the design technology of 2.5D glass, due to lack of experience and insufficient skills, they will always encounter one or another problem.
Take Xiaomi Note as an example. Although the front panel adopts a 2.5D glass design, due to the insufficient curvature of the 2.5D glass, the visual effect is actually the same as the ordinary glass panel, plus the magnesium-aluminum alloy middle frame for CNC carving. The next sharp ridgeline bright surface, the smooth transition of the 2.5D glass that should have brought the hand feel no longer exists, instead it is the split of the hand feel. Another example is nubia Z9 in order to use optical refraction to cover the black edges of the screen. It uses 2.5D glass with a thickness of 1.7mm. The curvature is exaggerated. Distortion and color banding caused by optical refraction will appear on both sides of the screen, which are formed when you look at the screen sideways. The effect of a prism, causing image distortion.
Industrial design who shows their magic
Various mobile phone manufacturers are keen to use 2.5D glass for their flagships, but most mobile phones only use 2.5D glass on the front. If the front 2.5D glass reflects the brand's yearning for beauty, then the choice of 2.5D curved glass on the front and back at the same time demonstrates the brand's interpretation of beauty.
