Laser Marking Machines for Reflective Materials|Adjustment Strategies for Laser Marking Parameters on Metals with High Reflectivity

The company has developed a systematic solution to the problem of adjusting the energy parameters of laser marking on highly reflective metals.The company's engineers have analyzed the relationship between the properties of various metal materials and the energy of the laser, and have shared strategies for adjusting the laser's power, frequency, and speed to avoid problems such as burning or oxidation.

Metal materials with high reflectivity, such as stainless steel and aluminum alloys, often present problems in adjusting energy parameters.First, it is necessary to understand the reflectivity of the material surface to the laser wavelength. For instance, the reflectivity of a 1064nm fiber laser on the surface of a mirror-like metal can reach 80 % or more.This requires that energy losses be compensated for by adjusting the parameters, while at the same time avoiding overburning.The first step is to set the initial power at between 30 and 40 percent of the equipment's rated power, and then gradually increase it in increments of 5 percent, observing the color changes. When a stable gray reaction appears, record the critical value.

The frequency parameter directly affects the amount of energy deposited in a given area.For scenes requiring fine patterns, it is recommended to use a high-frequency, low-energy mode (80-120 kHz), combined with a reduced scanning speed (400-600 mm / s), to ensure that energy accumulates. Coarse-line markings can be made using a low-frequency, high-energy combination (20-50 kHz).Special attention should be paid to calculating the overlap rate, which can be verified using the formula: overlap rate = (1 - scan speed / (frequency x beam diameter)) x 100 %. It is recommended that the overlap rate be controlled between 30 % and 50 %.

Environmental factors also need to be taken into consideration.In the summer, when the temperature in the workshop rises, the actual output of the laser may fall by as much as 5-8 %. At such times, the set value can be adjusted or the cooling system can be improved.For different metals, the parameters need to be adjusted accordingly. For stainless steel, it is recommended to use a progressive energy increase method, while for aluminum, it is necessary to use a more precise Q-switch control to inhibit oxidation.Finally, I would recommend that a parameter matrix be established. This would record the best combinations of parameters for different materials and surface conditions. The equipment would then be calibrated monthly to ensure stability.
