Introduction of Material Selection for 532nm Green Laser Marking Machine

Due to different materials, laser marking machines have relatively different uses. Therefore, when we purchase laser marking machines, the expensive ones are not necessarily good for us, and the ones that are suitable for our purposes are the most important. Today we will lead you to explain some purchasing skills of laser marking machine from the aspect of material.

Green laser marking machine

Before purchasing a laser marking machine, we must first confirm the material of our product, because different materials absorb the laser to different degrees, and the degree of absorption is determined by the wavelength of the laser. Different laser wavelengths are named as different laser sources. Therefore, different laser sources should be selected for different materials.

Green laser marking machine-glass inner engraving, inner plane engraving

Many users will ask, can only one type of laser source be used for engraving with one material? The answer is of course no. Some materials are suitable for multiple laser sources, but they have different levels of laser absorption for different wavelengths, and the effect is good. There is a difference, depending on the user's acceptance. For example: glass engraving can use three laser sources: carbon dioxide, ultraviolet, and green light. The effect: carbon dioxide laser marking machine-glass marking is relatively rough and easy to produce glass slag; ultraviolet laser marking machine-cold light source, glass marking is very Fine and uniform; green laser marking machine-glass internal carving, internal plane carving.

Engraving glass requires UV 3W laser

In addition to choosing the right laser marking machine, the power is also important. For UV-engraving paper, film, and plastic, it is also possible to use low-power 1.2W marking. If you are engraving glass, you need UV 3W or even 5W. The power can only move.

For example, for hardware marking, 20W optical fiber is generally used for marking. If efficiency and speed are pursued, the high power of 30W optical fiber is of course more efficient. Of course, to finally determine whether the power purchased by yourself is the most suitable, it is recommended to test with specific samples, depending on the effect and marking time.

The above is the introduction to the selection of laser marking machine materials shared by the editor. Again, in the actual purchase, we need to purchase a suitable laser marking machine according to the different materials of the products we want to mark. , Do not buy blindly.
