In addition to CO2 laser marking machine, UV laser marking machine and fiber laser marking machine are the major types of laser marking machine in the market. So which is better? Fiber laser marking machine or the UV laser marking machine? Well, it’s quite complicated to decide, as they both have their pros and cons. But first, let’s look at the differences of these two.

1.Laser source is different
Fiber laser marking machine adopts fiber laser as the laser source while UV laser marking machine adopts UV laser as the laser source, as their names suggest.

2.Working principle is different.
Fiber laser marking machine posts high energy laser light on the material surface so that the surface will evaporate and then the inside of the material will appear.

But for UV laser marking machine, it uses short-wavelength laser light to break the molecular chain of the material so that the programmed characters or patterns will appear.

3. Application is different
Fiber laser marking machine is suitable for marking metal. Because of amount of heat generated, it is not suitable for high precision marking.

On the contrary, UV laser marking machine, because of its “cold processing” feature, it is quite ideal for high precision marking, such as PCB, computer components, industrial bearings, watches, communication products, automobile parts, jewelry and plastics and so on.

So what are the advantages for fiber laser marking machine and UV laser marking machine respectively?

1.Advantages of fiber laser marking machine

1.1 High quality laser beam
This high quality laser beam ensures the laser marking is permanent and won’t fade out because of environment changes. The markings are quite delicate and beautiful

1.2 Long service life
The service life of fiber laser marking machine could reach 100,000 hours

1.3 Environmental friendliness
Fiber laser marking machine won’t produce any pollution or noise.

1.4 Low maintenance

2.Advantage of UV laser marking machine

2.1 Ability to perform ultra-precise marking and marking on special materials
This results from its ultra-small focus and tiny heat-affecting zone.

2.2 The feature of “cold processing”
As mentioned before, UV laser marking machine uses laser light to break the molecular chain of the material, so it won’t produce heat during the operation. Therefore, the damage to the material is also zero.

2.3 Low energy consumption

From the above comparison, you can decide which is better for your own, as what is best for you is what most suits you. But there is one thing that needs to be mentioned, since UV laser marking machine is often used to perform precision marking, the precision needs to be maintained by an air cooled recirculating chiller. S&A Teyu CWUL-05 UV laser cooling chiller is specifically designed for cooling UV laser marking machine from 3W-5W. This air cooled recirculating chiller is characterized by ±0.2℃ temperature stability and 370W cooling power. With 2-year warranty, users can rest assured using this UV laser cooling chiller.
