If the power of a laser marking machine is unstable during use, it will affect the marking effect. Therefore, when selecting a laser marking machine, you need to choose the appropriate laser marking machine according to your own marking requirements. So if you encounter unstable marking power, we should find the reason from what aspects? How can we choose a laser marking machine that suits our needs? Let's take a look at Xiaobian below.

Common reasons for unstable power of laser marking machines:

1. Laser marking speed is too fast.

2. The laser power supply voltage drops, resulting in a drop in laser output power.

3. Marking density: At the same format, the same light spot, and the same depth, the higher the marking density, the slower the corresponding marking speed will be. The reason is that the density directly increases the marking area.

4. Marking width: Because the deflection area of the vibrating mirror for large-format marking increases, the marking speed for large-format is slower than that for small-format surfaces.

5. Marking depth: According to needs, if the marking depth needs to be deepened, the parameters of the fiber laser marking machine need to be adjusted, the power, current and other factors of the fiber laser marking machine need to be adjusted, so the marking speed will be affected during these processes.

6. Laser spot size: The smaller the spot, the smaller the marking volume. Therefore, the larger the spot, the faster the marking speed.

Purchasing skills for laser marking machine:

First, determine what material you want to mark is, whether it is steel or leather, plastic or acrylic ceramics. Only when you determine the material can you decide what kind of laser marking machine to buy.

Second, determine whether the pattern or text you want to mark is complex and whether the machine you purchase can achieve what you want in terms of hardware or software choices.

Third, determine the area of the material you are marking, and whether the laser marking machine you have purchased can meet the marking task, because not every laser marking machine will accept the marking task of area, and large-area laser marking machines should pay attention to whether the laser output at each point is stable during marking.

Fourth, what is the hardware of the laser marking machine? The hardware includes what we call the laser head, the galvanometer, the internal chip and others.

Fifth, the engraving speed is different for each laser marking machine. Because the inherent hardware structure is different, there are also differences in marking speed.
