Practical Demonstration: Setting Laser Parameters for Different Materials

By means of practical demonstrations, they offer detailed explanations of the methods for setting laser marking parameters for common materials such as metals, plastics, and wood, including key parameters such as power, speed, and frequency. This helps users quickly resolve problems such as unclear marking effects and burnt materials, thus improving marking efficiency.

Why is it so important to set the parameters?

Although laser markers are easy to use, if the parameters are not set correctly, the image will be blurry, or the material will be burned and pitted.In particular, different materials have vastly different absorption rates for laser energy. For example, metals require high power, while plastic will melt if you are not careful.Below we show you how to "tailor" the settings to your particular needs.

Set metal material parameters.

Stainless steel engraving techniques.

The power should be set at about 30 %, and the speed at about 800 millimeters per second.If the markings are not obvious, the power can be increased gradually to 50 %, but don't go above that, or you risk burning the material.Remember to use the air-assisted blowing to reduce the amount of oxidation on the surface.

Parameters of aluminum alloys.

This material has a high reflectivity, so it requires a higher power output (60-70 %) and the speed drops to 600mm / s.A frequency of 20 kilohertz is more appropriate.If you are worried about the label turning black, try selecting "fill spacing" in the parameters and lowering the density to 0.08 mm.

Non-metallic material parameter adjustment.

How do you adjust for plastics?

The most important thing is to control the power at 10-20 %, and to move at a speed of over 1000mm / s.For materials like PVC, it is best to use a low frequency (5 kHz), while acrylic requires a high frequency (50 kHz) to produce a fine effect.

Woodcarving parameters.

Hardwood can be cut with 25 % power and 400 mm / s to produce a three-dimensional effect, but softwood needs to be set at 15 % power to avoid carbonization.If you want to make the marking deeper, don't adjust the power, just increase the number of times you mark it.

A Quick Guide to Common Problems.

When the color of the marks is uneven, first check whether the focus has moved more than two millimeters.If the pattern has too many jagged edges, try adjusting the frequency by 20 %.If you can't be sure of the parameters for a new material, remember the rule of "low power, high speed" and start testing with a small area, rather than risk scrapping the workpiece.

A few tips on how to record parameters.

It is best to get into the habit of specifying the material thickness when naming the file (for example, "ABS_3mm_参数组").If you need a special effect, you can just write "frosted glass" or similar in the notes section and next time you need it, it won't be a hassle to find.
