Application of Laser in Glass Processing

Glass is widely used in automotive, photovoltaic, display screen, home appliance and other fields by virtue of its versatile shape, good light transmission and controllable cost. The demand for glass processing in these fields is increasing, while higher precision, faster speed, and greater flexibility (such as curve processing and irregular pattern processing) are required. However, the fragile nature of glass also poses a number of processing challenges, such as cracks, chips, and uneven edges. Let's learn how lasers can cope with glass materials and help glass processing improve yields.

Glass laser cutting
Among the traditional glass cutting methods, the more common ones are mechanical cutting, flame cutting, waterjet cutting, etc.

Advantages and disadvantages of traditional glass cutting methods
The traditional cutting process suffers from slow speed, high cost, limited processing, difficult positioning and prone to glass chips, cracks, chipping and other phenomena. In addition, the traditional cutting process may require various post-processing steps (such as rinsing, grinding, polishing) to alleviate these problems, which inevitably adds additional production time and costs.
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 glass, through the way of thermal fusion, the formation of longitudinal and lateral burst point, so as to change the molecular bond of the material, can avoid residual stress in the glass, no dust pollution, can achieve 0 taper cutting, and chipping can be controlled within 10um It is easy to control and environmental protection, and also solves many problems in the traditional cutting process.
For glass laser cutting, Golden Orange has launched Golden Orange Glass Cutting System, or (P2000) for short. The system includes PSO function (arc at 500mm/s speed, point spacing accuracy ±0.2um), which can cut glass with high speed and high precision, and with post lobe process, get high quality glass shape products. The Golden Orange glass cutting system has the advantages of high precision, no micro-crack, breakage or fragmentation problems, high edge breakage resistance, and no secondary manufacturing such as rinsing, grinding and polishing, etc., which significantly improves the workpiece yield and processing efficiency while reducing costs.

Applications
Golden Orange glass cutting system can process ultra-thin glass, capable of cutting 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 process, but also can process through holes of different sizes on glass, and also micro holes.
Golden Orange's glass laser drilling solution can process various glass materials such as quartz glass, curved glass, ultra-thin glass, etc. with high controllability point by point, line by line and layer by layer with high flexibility, and can process square holes, round holes, waistline holes and other arbitrary shapes with the advantages of high speed, high precision and good stability.
Golden Orange glass laser drilling solutions can be applied to photovoltaic glass, display screens, medical glass, consumer electronics and 3C electronics, etc.
As the skill of manufacturing glass deepens, the technology of glass processing never stops. With the advent of laser, there are new options for glass processing methods, and with the precise control of the laser control system, finer and more efficient processing methods become the new choice for people.
