How to choose fiber laser marking machine among 20w 30w 50w 100w

Before choosing fiber laser marking machine, let us know firstly how it works.
The laser marking is with a laser beam to get permanent marks on a variety of different material surfaces.
The effect of marking is to expose the deep matter by the evaporation of the surface material,
or to “mark” the trace by the chemical and physical reactions of the surface material caused by the laserenergy,
or to burn some of the material by laser energy, light to achieve the needed patterns and text.

There are 20w 30w 50w and 100w in current laser marker. Different laser power can achieve different results.
Now we are moving to the work performance each power can do.
1. 20w fiber laser marking machine.
It is the minimum laser power now, also with more competitive price, most cost-effective machine.
It is mainly for marking on material surface, like steel, brass, coated metal. For engraving, it has capacity limit.
It can not engrave too deep and engraving time will be very long. Meanwhile the engraving result is also not good.
E.g. It at most can engrave 0.5mm on steel with 20 minutes or longer time.
2. 30w fiber laser marking machine
30w has more peak power than 20w. Besides same marking ability, 30w can also do better engraving with faster working speed.
For cutting, most of customers cut gold and silver. 30w also has much good performance on that.
It can cut maximum 0.5mm silver and 1mm gold.
Based on those, no matter on performance, but also on cost, 30w is also the most popular type.


3. 50w fiber laser marking machine
50w can be treated as the updated version of 30w. For choosing 50w, it is mainly for engraving and cutting.
Compared with 30w, it will take almost half using time for engraving or cutting same materials.
Of course it can cut 0.3mm thicker silver and 0.5mm gold than 30w, and 50w can cut 1mm stainless steel sheet
4.100w fiber laser marking machine
It seems one new product for the new requirements of thicker cutting and deeper engraving. 100W is good, but price is very
expensive, so in market it is rare to see. If take cost-effective ratio into consideration, honestly speaking we do not recommend it
In conclusion, if you mark most and not deep engraving, 20w is the first choice.
If you mark and engrave often, prefer a faster marking speed, you can consider 30w. 20W and 30W are same application, difference
between 20W and 30W is that 30W can engrave with a certain depth, and if engrave same depth, 30W working speed is more faster
than 20W laser
If you need higher efficiency of engraving and cutting some thin material, also budget is enough, 50w is better.
Actually 20w 30w and 50w can meet 90-95% needs. so 100w is only one good reference for some special requirements for industry
