How to choose the fiber laser marking machine

Laser marking is a commonly used marking and engraving technology, which has a wide range of applications in various industries and fields. Laser marking power and marking depth are important factors affecting the marking effect. This article will introduce the relationship between laser marking power and marking depth, and provide relevant marking data support.

First of all, laser marking power has a great influence on the marking depth. Usually, higher power laser marking machine can realize deeper marking depth. Take metal materials as an example, the use of laser marking machine power of 20 watts, can achieve about 0.02 mm marking depth. With a 50 watt laser marker, the marking depth increases to approximately 0.05 millimeters. When the power is further increased to 100 watts, the marking depth can reach about 0.1 mm. This shows that laser marking power and marking depth are positively correlated.

Second, in addition to laser marking power, there are other factors that can affect the marking depth. One important factor is the material properties. Different materials have different absorption and conduction ability of laser light, so under the same power, the marking depth of different materials will be different. For example, for the same power of laser marking machine, the marking depth may be greater on metal materials than on plastic materials.

In addition, laser marking speed also has an effect on marking depth. In general, slower marking speeds achieve deeper marking depths, while faster marking speeds result in shallower marking depths. This is because slower marking speeds allow the laser to interact with the material for a longer period of time, resulting in a deeper impression.

Finally, the choice of laser marking depth should be weighed against the actual requirements. For applications that require a shallow marking depth, such as surface marking and labeling, a lower power laser marker may be more appropriate. For some applications that require deeper marking depth, such as two-dimensional code engraving and graphic engraving, higher power laser marking machine may be more suitable.

In summary, there is a close relationship between laser marking power and marking depth. Higher power laser marking machines can usually achieve deeper marking depth. However, in addition to laser marking power, material properties and marking speed also have an impact on marking depth. When choosing the laser marking depth, the actual demand and material properties should be considered comprehensively. Through the above marking data, we can better understand the relationship between laser marking power and marking depth.
