Jan 06 , 2023Why the Nanosecond UV Laser Marking Machines is the best choice for marking High Quality Plastic
Nanosecond UV laser marking machine has high efficiency and good effect for plastic. With the improvement of living standards, people begin to pursue personalization when buying products.
Plastics can be roughly divided into: PE, PP, HDPE, AS/SAN, ABS, PVC , PMMA (acrylic or plexiglass), PET, PA, PC and so on.
Different types of plastics have different absorption rates of laser energy. Some plastics can easily absorb laser energy and are easy to mark; while some plastics do not absorb laser energy and cannot produce high-quality marks, or even make them.
Why does this happen? Because the absorption rate of laser energy is a function of wavelength, different plastics will get different quality marks under the same laser intensity. So, how can laser marking of plastic products produce high-quality marks?
1. According to the plastic material and the effect to be marked, select the appropriate laser marking machine model:
The Fiber fiber marking machine, UV fiber laser marking machine, and co2 laser marking machine are produced by TRIUMPH Laser can mark plastics. Because different types of lasers emit light of different wavelengths and have different penetrating capabilities; and the adaptability of different lasers affects the marking quality and marking speed, so different materials of plastics, plastics of the same material with different purity, and the same material The type of laser marking machine used will be different for different plastics in the post-processing process.
In addition, each customer has different marking requirements. Therefore, which laser marking machine is most suitable for your product. We need to know your plastic material and engraving requirements to determine.
2. Add laser marking powder
Laser marking powder, also called laser powder, laser additive, laser marking additive, plastic laser marking powder, etc. It is mainly used for PP, PE, PA6, PA66, PBT, PVC, ABS, TPU, PS, TPE, TPV, TPR, PET, PC, POM, SEBS, PEI and other plastic plastic materials when engraving It is not clear or can not be marked. A special substance must be added, which can make the plastic marking clearer and will not fade due to physical or chemical factors.
It can make the white plastic type black graphic characters. A short description is that it is white and black, and it can also be colored black, black and white, and black and gold. The main purpose of laser marking powder is to absorb laser energy, convert the laser beam into heat energy, and produce heating, carbonization, evaporation and chemical reactions on plastics and plastics, thereby making it easier to mark plastic and plastic products. The laser marking is not clear. It becomes clearer and brighter, and those that cannot be marked can be marked clearly.
