Glass is widely used in automotive, photovoltaic, display, and home appliance applications due to its versatile shape, good light transmission, and controllable cost. The demand for glass processing in these fields is increasing, and at the same time, higher precision, faster speed, and greater flexibility (such as curve processing and irregular pattern processing) are required. However, the fragile nature of glass also brings a lot of difficulties to processing, such as cracks, chips, uneven edges, etc. Let's find out how lasers can cope with glass materials and help glass processing to improve yields.
Glass Laser Cutting
In the traditional way of cutting glass, the more common are mechanical cutting, flame cutting, waterjet cutting and so on.
Advantages and disadvantages of traditional glass cutting methods
The traditional cutting process has the problems of slow speed, high cost, limited processing, difficult positioning and easy to produce glass chips, cracks, chipping and other phenomena. In addition, traditional cutting processes may require various post-processing steps (e.g., rinsing, grinding, polishing) to alleviate the above problems, which inevitably adds additional production time and cost.
With the development of laser technology, cutting glass process also appeared in the figure of laser, laser cutting glass is a non-contact process, laser focus on the middle layer of the glass, through the way of thermal fusion, the formation of longitudinal and transverse bursting point, thus changing the molecular bonding of the material, to avoid the production of residual stress in the glass, no dust pollution, can achieve 0 taper cutting, and chipping can be controlled in 10um The chipping can be controlled within 10um, which is easy to control and environmentally friendly, and also solves many problems in the traditional cutting process.
For glass laser cutting, Orange Gold launched Orange Gold glass cutting system, referred to as (P2000). The system contains PSO function (500mm/s speed arc, point spacing accuracy of ± 0.2um), can be high-speed, high-precision cutting of glass, with the latter part of the process, to obtain high-quality glass shape products. The Golden Orange glass cutting system has the advantages of high precision, no micro-cracks, broken or fragmented problems, high rupture resistance at the edges, no need for secondary manufacturing such as rinsing, grinding, polishing, etc., which dramatically improves the workpiece yield and processing efficiency while reducing costs.
Golden Orange glass cutting system can process ultra-thin glass, can cut complex shapes and patterns, commonly used in cell phones, consumer electronics, 3C electronic products, automotive center control glass, smart home display, glassware, lenses and other fields.
Glass Laser Drilling
Laser can not only be applied in glass cutting and processing, but also can process through holes with different sizes of apertures on glass, as well as micro-holes.
Golden Orange's glass laser drilling solution can process various glass materials such as quartz glass, curved glass, ultra-thin glass and other glass materials point by point, line by line and layer by layer with high controllability and flexibility, and it can process square holes, round holes, waistline holes and other arbitrary shapes, with the advantages of fast speed, high precision and good stability.
Orange Gold's glass laser drilling solutions can be applied to photovoltaic glass, displays, medical glass, consumer electronics and 3C electronics.
