Optimization of Laser Marking Parameters

The parameters of a carbon dioxide laser marking machine directly affect the quality and efficiency of processing.By rationally adjusting core parameters like power, frequency, and speed, and by optimizing the laser's performance according to the characteristics of the material being worked on, it is possible to dramatically improve the speed and precision of laser marking.The company also provides practical solutions, such as cleaning the optical path and resetting parameters, to common problems such as burrs and blurred images, helping users quickly master the techniques for fine-tuning their equipment and reduce processing costs.

Why is parameter setting so important to the marking effect?

Though CO2 lasers have powerful performance, if the parameters are not set properly, the results may be disappointing.For example, if the power is too high, it will burn the material; if the speed is too fast, the mark will be unclear.Most users, when they actually start to operate the machine, often encounter problems with uneven depth or unclear patterns, due to inappropriate combinations of parameters.Only by fully understanding the relationships between the various parameters can the potential of the equipment be fully realized.

Key points of the central parameters.

Balancing power and frequency.

Power determines the strength of the laser, while frequency affects the number of pulses per unit of time.For example, with acrylic plastic, if the power is set to medium (30-50 %), and high frequency (above 20kHz), it can prevent the material from being deformed.For metals, the power level needs to be higher (60 % to 80 %), but the frequency needs to be appropriately lowered to prevent excessive burning.

The speed of the train and the spacing of the stations.

If you go too fast, you can break a line; too slow and you waste time.The smaller the spacing, the finer the pattern, but the processing time increases exponentially.He suggests that users start with a small area, setting the speed at 500 mm / s and the gap at 0.05 mm, and then adjust according to the actual results.

Practical techniques for improving processing efficiency.

Pre-treatment of the raw materials is crucial.

Many users ignore the need for cleaning and coating.For example, spraying the glass with a special marking fluid before engraving greatly improves the contrast, and reduces the number of times the work must be engraved, saving 20 % in time.

Optimizing the parameters for batch processing.

For a batch of identical products, the same parameters should be used.If you are using materials of different thicknesses or made of different materials, it is suggested that you group them in advance to avoid having to adjust the machine too often.Moreover, the equipment's "parameter set storage" function allows for quick switching of configurations, doubling efficiency.

Common problems and quick solutions.

If the edge of the cut is jagged, first check whether the lens is dirty, and then try reducing the frequency.If the patterns are not uniformly deep, the workbench may not be level, or the focus may need to be re-calibrated.Remember: 80 % of problems are solved by "cleaning the light path + resetting the parameters.
