Table of Laser Marking Parameters for Different Materials

The article provides detailed information about the power, speed and frequency of laser engravers, and the ways in which these parameters need to be adjusted to suit the characteristics of different materials such as metal, plastic and ceramics.The system provides recommended settings for commonly used materials such as stainless steel and acrylic, as well as guidance on fine-tuning parameters and solutions to problems that may arise during the marking process. This allows operators to quickly achieve the best marking results and avoid problems such as material damage or unclear markings.

The relationship between laser marking parameters and materials.

To mark metal, plastic, and other materials with clear, long-lasting marks, you need to adjust the power and speed just as you would adjust the temperature for different foods. You can't just start operating the machine without first determining the type of material.

Parameters for metal materials.

Stainless steel and aluminum alloys are frequent visitors to the workshop, but these tough guys need a heavy blow to crack them.He recommends setting the power of the fiber laser at 80-120 watts and controlling the speed at 800-1,200 mm per second.Remember not to exceed 50 kHz, or else you may burn the surface of the metal.

Plastics manufacturing techniques.

When working with ABS and acrylic, which are very delicate materials, you have to learn to be gentle.With power reduced to the 20-40W range, speed can be raised to 1500-2000mm / s, and frequency should be kept at 20-30kHz.In particular, when processing black plastic, adding 3-5 % more ink density can make the marking more visible.

Special arrangements for ceramics and glass.

This sort of brittle material, like porcelain, is best handled with a Q-switched laser.The best results are obtained by setting the power to 30-50 W and the speed to 500-800 mm / s.Remember to keep the frequency between 15 and 25 kHz, and to test the machine on scrap material first.

Practical experience in adjusting parameters.

Don't be bound by the standard parameters. When actually doing the labeling, you have to be as flexible as an old chef tasting his food.If the temperature in the workshop fluctuates more than 5 ° C, the power must be adjusted by 2-3 %; and when working with highly reflective materials, a 10 % increase in pulse frequency can produce surprising results.

Common problems and emergency solutions.

If you notice that the color of the label is yellowing, it could be that the wattage is too high; try reducing it by 5 W.If the lines appear with jagged edges, don't panic. Just increase the speed by 200 mm / s.If the marks are not all of the same depth, check whether the focusing lens should be cleaned.
