How to choose the power and frequency of the laser marking machine?

In the marking of metal and plastic using a laser marking machine, there is a range of setting parameters for reference tests. The speed is adjustable from 100-2000, the power is adjustable from 30-80, and the frequency is 5-30. Depending on the different materials and the marking effect you want, a new operator may need to perform dozens of experiments to understand the ideal marking parameters for each material, even some experienced engineers have to try several times. This article gives a brief introduction about laser marking frequency,power,speed for a laser marking machine .


The following knowledge points are listed below:

  • The three parameters of setting the laser marking machine

  • Setting the frequency of the laser marking machine

  • Setting the power of the laser marking machine

  • Setting the speed of the laser marking machine


1.  The three parameters of setting the laser marking machine

There are three settings will affect the marking result in order to get a good laser marking result: the speed, the power, the frequency parameters should be sets.


2. Setting the frequency of the laser marking machine

In a laser marking machine, the marking frequency represents the number of laser pulses per unit time, and is called the marking frequency. It's easy to understand. For example, when the marking frequency value is high, the laser spot is dense, and conversely, when the marking frequency value is low, the laser spot is resolved.

Although the laser spot is invisible to the naked eye, it can be seen when the marked workpiece is placed under an electron microscope. The continuous lines we saw with the naked eye were originally composed of many laser spots. The higher the value we set on the marking frequency, the denser the laser spot, and the better the finish of the marking workpiece.


3. Setting the power of the laser marking machine

Marking power. In the parameter setting, the power is adjusted by percentage, and the output power can be adjusted from 0% to 100%. The default power is usually 50%. The higher the laser power you set, the stronger the laser output energy you get, and the easier the marking depth will be. You need to set the laser power according to your actual needs. Because the laser output energy is too large, it will have a greater impact on the material. As long as the laser power meets your marking requirements, you do not need to set a very high laser power, otherwise long-time high-power marking will damage the laser generator and affect the life of the laser generator.


4. Setting the speed of the laser marking machine

The marking speed of the laser marking machine refers to the moving speed of the laser. Here this speed is the speed that can be adjusted in the marking parameters. The overall marking time is not only affected by the marking speed, but also by factors such as the marking depth and the marking area. The higher the speed you set, the faster you get the markup.


Fast marking speed, less laser marking times. Slow speed is more conducive to deep marking. But this does not mean that the slower you set it, the better the depth you get. It also depends on the different materials and other related parameters you set.

If the marking speed of the laser marking machine is too slow, the material burned by the laser will accumulate on the surface of the material, affecting the laser scribing deeper. When you are doing deep marking, it is best to do high speed marking after several low speed markings. This way you will get better results.


Laser marking machine may have several parameters that are programmable and can affect the results you achieve on a specific material or substrate. Different combinations are ideal for specific materials. After reading this article, do you know how to setting the parameters of the laser marking machine now?
