While you can also use laser engraving techniques to mark your other types of glass, these are the types of glass that are primarily used in the industry for engraving. This is a demo video of how the laser engraver for glass products works in real time.
Common types of laser glass marking technology
The laser marking technologies on glass products mainly include laser engraving and etching. There are subtle differences between the two technologies.
However, both techniques are used for the purpose of marking glass products. Here are the basic differences between the two tagging techniques:
Laser engraving of glass products
Laser engraving on glass products is the same as any other engraving method. This means that part of the glass is cut from its original body. You can feel the difference in contour on the glass after the engraving is done.
Typically, the laser energy used to engrave glass is higher because a portion of the material is vaporized. The engraving depth depends largely on the hardness of the glass to be marked and the power of the laser.
Laser etching of glass products
Laser etching on glass materials is slightly different than engraving. In laser etching of glass, only a small layer of material is removed from the main material. Therefore, the laser does not cut deep into the material.
Conversely, removing the top layer in the desired way leaves the design that the designer asked for.
CO2 and UV Laser Engraving
When it comes to the type of glass you have to engrave, you have to choose the right laser source to choose from. The basic difference between CO2 and UV lasers is the intensity of the marking.
UV lasers for glass are often used when etching and fine designs are required. However, when laser engraving is required, a CO2 laser is ideal because it can generate more heat for a given input power.
On the other hand, if you want to etch your glass, then you can use a UV laser system. This is because UV light also has a chemical effect on the glass surface.
The advantages of using laser engraving machine for glass products
As laser engravers continue to evolve, you can achieve superior quality and precision when engraving glass products. This technological advancement offers you the opportunity to turn the most complex designs into high-precision glass products. Furthermore, the repeatability of the process does not compromise the accuracy of the engraving.
Cost savings through material savings
Since the engraving process is non-contact and fully automated, there is no damage to the material. Furthermore, it ensures that the process has minimal damage to the machine and product. This damage is relatively high in other types of engraving methods.
Easy to use
All other engraving techniques on glass require a higher level of skill as well as hand cleanliness. However, in laser engraving technology, the automation of the process takes care of the skills and produces the highest quality product in the easiest way possible.
Neat finished product
In other engraving methods, finishing touches are often required after engraving is complete. However, in laser engraving machines for eyeglasses, little or no decoration and cleaning is required at the end of the engraving process.
Therefore, glass laser engraving has many advantages that other engraving methods do not have.
