In addition to CO2 laser marking machine, UV laser marking machine and fiber laser marking machine are the main types of laser marking machines on the market. So which one is better? Fiber laser marking machine or UV laser marking machine? It is quite complicated to decide because they both have their advantages and disadvantages. But first, let’s look at the difference between the two.
1. Different laser sources
Fiber laser marking machine uses fiber laser as the laser source, while UV laser marking machine uses UV laser as the laser source, as the name suggests.
2. Different working principles.
Fiber laser marking machine irradiates high-energy laser on the surface of the material, causing the surface to evaporate, and then the inside of the material appears.
While UV laser marking machine uses short-wave laser to break the molecular chain of the material, so that the programmed characters or patterns appear.
3. Different applications
Fiber laser marking machine is suitable for marking metals. Due to the high heat generation, it is not suitable for high-precision marking.
On the contrary, UV laser marking machine, due to its “cold processing” is very suitable for high-precision marking of PCB, computer components, industrial bearings, watches, communication products, auto parts, jewelry and plastics.
So what are the advantages of 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 that the laser marking is permanent and won’t fade out due to environmental changes. The marking is very delicate and beautiful
1.2 Long service life
The service life of the fiber laser marking machine can reach 100,000 hours
1.3 Environmentally friendly
The fiber laser marking machine won’t produce any pollution or noise.
1.4 Low maintenance
2. Advantages of UV laser marking machine
2.1 Capable of ultra-precision marking and marking on special materials
This is due to its ultra-small focus and tiny heat-affected zone.
2.2 Features of “cold processing”
As mentioned earlier, the UV laser marking machine uses laser to break the molecular chain of the material, so it won’t generate heat during operation. Therefore, the damage to the material is also zero.
2.3 Low Energy Consumption
Through the above comparison, you can decide which one is more suitable for you, because the one that suits you best is the best. But one thing needs to be mentioned, since UV laser marking machines are often used for precision marking, air-cooled circulating chillers are required to maintain accuracy. S&A CWUL-05 UV laser cooling chiller is designed for cooling 3W-5W UV laser marking machines. This air-cooled circulating chiller features ±0.2℃ temperature stability and 370W cooling power. With a 2-year warranty, users can use this UV laser cooling chiller with confidence.
