玻璃标记

Internal and external laser marking of glass

Whether you need an internal mark or surface etching, our laser glass marking systems can meet your needs. Due to its many advantages over traditional marking techniques, laser marking is found in an increasing number of industries—bringing flexibility, speed and repeatability to your application.

Other advantages include:

  • No consumables。万博manbetx手机下载激光标记不需要额外的消耗品,例如爆破砂,墨水打印和其他玻璃标记方法。
  • Repeatability。Laser marking is extremely accurate and repeatable due to the laser’s localized energy and system’s accurate controls.
  • Flexibility。激光可以蚀刻各种图形和文本,包括复杂的模式。由于我们的自定义软件功能,在不同零件之间切换也很简单。
  • 没有模具或口罩。Our marking systems steer the laser like a pencil on paper—eliminating specific masks for each design. Marking a new design is as simple as uploading a new drawing file.
  • Easy automation。You can easily add laser glass marking to your automated operation. Our systems even mark glassOn-the-Fly

内部和外部标记方法

The two basic glass marking methods are external and internal marking. External glass marking utilizes lasers to etch the surface of the glass part—causing light to reflect off the surface and creating a contrasting mark to the eye.

External marking uses the following laser wavelengths:

  • 10.6μm(二氧化碳激光器) - 标记表面的点几乎没有径向裂纹。这使得标记具有一致的外观并最大程度地减少额外的碎屑。二氧化碳激光器是标记玻璃的最快选择,并且在许多需要自动化或On-the-Flytechnology.
  • 355 and 532 nm (Nd:YVO4 lasers)—mark the surface with thin lines, or micro fractures—creating a frosted look. This method creates very intricate graphics and designs but is a slower process than CO2 marking.

Applications for external glass marking span many industries. Popular examples include:

  • 装饰玻璃标记
  • Nucleation
  • Marking rounded surfaces—the laser’s depth of focus gently marks even small variations in the surface of the glass, making laser marking suitable for rounded parts like wine bottles, stemware and other drinking glasses.
  • Automotive anti-theft glass marking—we manufacture a portable, handheld laser glass marking machine for etching VIN numbers onto automotive windows for anti-theft protection (U.S. Patent No. 8598489).

内部玻璃标记

该方法将激光的能量聚焦于玻璃部分的内部,从而创建微裂缝和视觉对比标记而不会影响外表面。内部玻璃标记使用355 nm(ND:YVO4)或超短激光器。它们的小点尺寸具有高能量密度和吸收率,可以标记玻璃内的精确位置。通过更改X和Y轴中的Z高度和扫描,您甚至可以在玻璃内标记3D图形。装饰玻璃标记是内部玻璃标记的最受欢迎的应用程序。

Backlit Graphic Marking

Another application for laser glass marking is to remove an opaque coating substance—paint, for example—from a glass surface in order to backlight the laser-removed areas. Depending on the coating, you can use many different laser wavelengths—from IR to UV—for this application. Wavelengths that are absorbed by the coating but transmitted by the glass are ideal. Lasers can remove graphics, text characters and even data matrices without damaging the glass.
