The relationship between mopa laser marking machine and fiber laser marking machine

What is the relationship between mopa laser marking machine and fiber laser marking machine? Are these two marking machines in the same category? Today, I will give you a detailed introduction.

If it is divided according to the wavelength of the laser, the mopa laser marking machine and the fiber laser marking machine belong to the fiber marking machine, because their wavelength is 1064nm, The two are a relationship of inclusion and inclusion. If both belong to fiber laser marking machines, why are mopa laser marking machines subdivided?

This is because their proofing effect and application range are not the same, and the pulse width of the two machines Different from the pulse frequency, mopa laser marking machine is suitable for fine marking process of metal and non-metal materials. Such as digital product parts laser engraving black, mobile phone keys, light-transmitting keys, mobile phone shells, key panels, electronic components, oxidation, plastic marking, handicraft gifts, oxidation treatment and coating electroplating spraying and other surface treatment.

Pay attention to the wording of fine marking. The fiber laser marking machine we said earlier is suitable for marking metal and non-metal hard plastics does not mean that it is fine. For example, it is difficult to make black effect with ordinary fiber optic machine such as alumina and some galvanized metals, but mopa laser marking machine can easily make black effect; for example, many friends consulted the marking requirements for the back cover of mobile phones If it can achieve the effect of the back cover of the iPhone, then the mopa laser marking equipment can be used to do it. The effect of the ordinary laser machine is not so fine and rough, but the mopa laser marking machine does not need to worry about such problems. Another example is the marking of silica gel surface coating. We should also be familiar with Nokia mobile phone cases, using mopa laser marking machine.

The pulse width of mopa laser marking machine M1 is 4-200ns, and the pulse width of M6 is 2-200ns. The pulse width of an ordinary laser machine is 118-126ns. From this, it can be seen that the pulse width of the mopa laser machine can be adjusted in a wider range, so it is understood why some products cannot be produced by ordinary optical fibers, but the mopa laser machine can do it. The pulse frequency of Mopa laser marking equipment is 45Khz, and the common one is 20-80Khz. For ordinary fiber optic machines, the larger the range of pulse frequency adjustment, the more difficult it is to grasp the high precision marking requirements.

I believe we should have a certain understanding of mopa laser marking machine after comparing and understanding the marking effect, pulse width and frequency. I don't think it will be mysterious because of multiple English letters. In fact, both devices are determined by lasers. Generally, laser manufacturers have mopa lasers. Maybe because the cost of lasers is different, the cost of the whole machine is also different.

Now everyone has a general understanding of the relationship between mopa laser marking machine and fiber laser marking machine. If there is anything unclear, please contact us consult.
