Glass products are widely used in construction, daily use, medical, chemical, household, electronic, instrumentation, nuclear engineering and other fields.Glass is fragile, so carving on the surface of glass requires a high level of craftsmanship.Laser marking machine non-contact processing, processing time is short, marking line fine, it is very suitable for the glass material surface for patterns or text information marking.Use a laser to mark the glass in the following ways.
Multiple laser radiation
Using a single laser radiation to produce a well-defined mark on the surface of the glass. After a few days, the laser spreads to the vicinity of the original mark to form a fragment, and then multiple radiations are used to heat the area adjacent to the marked area by heat conduction, so that these areas are formed. Stress gradients, thereby reducing the likelihood of secondary rupture, are very effective for marking on soda lime glass and borosilicate glass using this method.
The annular crack method is formed by discrete points
A series of circular cracks are used to form text, bar codes, square or rectangular codes and other shape code patterns.Low-density annular cracks are generated by the heating and cooling cycles of the glass.When the glass is heated, it expands and squeezes the surrounding material. When the temperature rises to the point of softening, the glass rapidly expands to form a dome on the surface of the glass with a low-density material.
The method of producing a cracked surface
The process of heating and cooling is used to change the affected glass surface, which is not immediately visible but begins to crack along the laser-marked area after a little pressure.The glass of chapped shape surface has the function of safe glass not only, still can have ice to crack not complete and transparent effect, because this USES extensively at interior decoration, if partition, setting wall, also can be used at vitreous furniture, get the love of consumer.
Laser on - line marking machine marking glass
Laser can form a very thin beam, in the glass material to achieve fine marking, any complex text, graphics, images, trademarks, LOGO, bar code, two-dimensional code, production batch number, autograph, etc., can be completed through the laser marking machine.
