Principles of Energy Matching in Laser Marking Parameters

The parameters set on the laser marking machine directly affect the results of processing, and energy matching is the most important part of the process.By analyzing the interaction of power, frequency, and speed, they share practical adjustment techniques that help users quickly optimize marking quality, avoid material damage, and increase efficiency.

Why is it so important to match energy?

Setting the parameters for a laser etcher is like controlling the heat for a dish. Too much power can burn the material, while too little won't leave a clear mark.The key to energy matching is to get the power, frequency, and speed of the laser just right, to ensure that the image is clear and beautiful and to extend the lifespan of the equipment.

Learn to understand the relationship between the three energies.

Power: The main switch for the total output of energy.

The power of a laser determines its "explosive force.Metal usually requires a high power setting (60-80 %), while materials that are easily carbonized like plastic and wood should be tried at a low power setting (30 %) and then gradually increased.Don't go full throttle right off the bat, just like how a sudden burst of speed can damage the engine.

Frequency: Laser-like, rapid-fire.

The higher the frequency, the more pulses in a given period of time.When carving delicate patterns, a higher frequency (over 20 kHz) is more appropriate, but when doing deep carving, the frequency needs to be lowered (5-10 kHz), so that the energy of each pulse is greater.Remember that frequency and power are inversely related, so they must be adjusted together.

Speed: the chisel of sculpture.

If the speed is too fast, the incisions will be too shallow, and if it is too slow, the material may be burned through.For beginners, the best approach is to start out at a medium speed, and then adjust as needed.For example, when carving stainless steel, a speed of 0.8 m / s in combination with medium to high frequency often produces good results.

Four steps to real-world adjustments.

Step 1: First, determine the properties of the materials.

Testing with scrap material is much more reliable than testing finished products. Metals, plastics and ceramics each have their own characteristics. Hard materials require high power and low frequency, and brittle materials require the opposite.

Step 2: Fix two notes.

The most common mistake made by beginners is to adjust all three parameters at once.It is recommended that you first fix the frequency and speed, and adjust the power until you find the point of greatest clarity.

Step 3: Check for results and find a balance point.

The key is to pay attention to the color and depth of the marks.If the metal shows a clear oxidized color, it means the power was too high. If the plastic edges turn yellow, it means the speed was too slow.Each time, we only adjust 5 % of the parameters. If we are patient, we will eventually find the optimum state.

4. Make a good parameter record sheet.

Keep a notebook in the workshop to record successful parameters: type of material, thickness, temperature, humidity, and so on.If we encounter a similar product next time, we can just apply the same technology, saving us a lot of testing time.

If you encounter blurry cuts, don't panic and rush to rework the piece. Try reducing the speed by 10 % while increasing the power by 5 %. If the material warps, immediately check the cooling system. The frequency may have been set too high, causing localized overheating.When you really get stuck, the technical support of the equipment manufacturers is a lot more reliable than the instructions on the Internet.

Finally, it should be noted that there is no universal formula for setting parameters.The best way is to keep experimenting and accumulating experience.It's like a veteran driver who knows how to shift gears by feel, and can master the art of energy matching.
