Solving the problem of fuzzy labeling

The settings of a laser marking machine directly affect the quality of the mark. Too much power can burn the material, while too little will not be deep enough. Frequency affects the continuity of lines, and must be adjusted according to the hardness of the material. Too fast a speed will make the mark appear blurred.When adjusting the laser, we recommend first fixing the focal length, and then optimizing the parameter combinations one by one. The first priority should be to match power with speed. Testing different schemes in conjunction with the material properties can quickly resolve the problem of blurry marks.

Why does the setting of parameters affect the results of the tagging?

The parameters of a laser marking machine are like "invisible switches" that control the "strokes" of the laser. A slight deviation in power, frequency, or speed can make the mark appear as if through a layer of fog.For example, if the power is too low, the surface of the material will not respond adequately. If the frequency is not right, the lines will be broken and uneven.Most fuzzy problems can actually be solved by adjusting parameters, but you have to know how to find the right direction.

How do you adjust the three key parameters to make the images clear?

Power: Don't assume "the higher the better.

Too much power will burn the material, while too little won't drill deep enough.For metals, a medium to high power setting (for example, 60-80 %) is generally used, while for plastics or coated materials, it is recommended that one start with a low power setting (20-40 %).If the marker turns white or the edges start to melt, turn down the power quickly.

Frequency: Determines continuity.

The higher the frequency, the more dense the laser points.For example, with a hard material like stainless steel, the frequency should be set above 20 kHz to achieve a finer finish. For wood or leather, on the other hand, 10 kHz is enough.If the edges of the marking are ragged, try increasing the frequency.

Speed: If you go too fast you'll "float.

If the speed is too fast, it will result in inadequate energy accumulation, and the markings will appear insubstantial.For metals, the recommended speed is between 300 and 800 mm / s, while for non-metals it can be raised to 1000-1500 mm / s.After adjusting the speed, you have to look back at the power, because the two parameters must be adjusted in conjunction.

A Guide to Avoiding Pitfalls in Parameter Tuning.

First fix the focal length and adjust the parameters, so as to avoid being blamed for poor focus. Each time only change one parameter, and immediately compare the results.If you come across a particularly stubborn problem, you can try the "power down 10 % + speed down 50 % "combination. This old-fashioned method has saved many an old hand from a bind.
