In the previous article, I learned about the parameters of our UV laser marking machine. Today, let's continue to take a look at the adjustment method of these parameters!
UV laser marking machine parameter adjustment method：
According to different marking needs, the parameters of the UV laser marking machine need to be adjusted in time. The following are our UV laser marking machine parameter adjustment recommendations based on factory testing and customer feedback on common materials and marking requirements：
1.UV laser marking machine for marking plastic materials：
Plastic marking usually requires lower laser power and higher scanning speed. Our UV laser marking machine can effectively remove some coatings or labels from the plastic surface to form a clear mark.
Laser power: low (generally 10%-50%)
Scanning speed: higher (improve efficiency, but ensure clarity)
Frequency: Higher (usually between 20-50kHz)
Pulse width: shorter (improve marking accuracy and clarity)
2.UV laser marking machine for marking metal materials：
Metal marking requires higher laser power, because the metal is more reflective and the laser energy is more difficult to absorb.Therefore, when marking metal materials, it is necessary to adjust the higher power and appropriately reduce the scanning speed.
Laser power: higher (usually 50%-80%)
Scanning speed: low (to ensure marking depth)
Frequency: lower (generally 10-30kHz)
Pulse width: moderate (to avoid overheating affecting the material)
3.UV laser marking machine for marking glass and ceramic materials：
Glass and ceramic marking usually relies on the high-precision focusing of it. Due to the high surface hardness of the material, higher laser power and lower scanning speed are required to ensure the depth and clarity of the mark.
Laser power: higher (60%-80%)
Scanning speed: lower
Frequency: higher (20-50kHz)
Pulse width: shorter (improve marking accuracy)
4.UV laser marking machine for marking coating materials：
The marking of coating materials requires fine control of the laser power to avoid excessive burning or removal of the coating.
Laser power: low (control the removal depth of the coating)
Scanning speed: higher
Frequency: higher
Pulse width: moderate
The parameter adjustment of it has a very important impact on the marking effect. According to the characteristics and marking requirements of different materials, we reasonably select and adjust the laser power, scanning speed, repetition frequency, pulse width, focal length and other parameters to achieve high-quality marking results. In our actual operation, the operator needs to have a full understanding of the material properties and processing requirements, and find the most suitable parameter combination through experiments and adjustments. The suggestions we give can only be your reference, but if necessary, you can contact us by phone, and we will try our best to give you better suggestions.
