Principle of Laser Marking
The laser emits a high-energy pulsed laser beam. When the laser beam acts on the material to be marked, the light energy is converted into heat energy under the action of the laser marking additive, which causes the surface of the material to melt, foam, discolor and even vaporize, thereby forming a graphic.
Characteristic of Laser Marking
Ø Non-contact processing, durable;
Ø High accuracy, fast labeling, clear graphics, and high mark reliability;
Ø Can produce high resolution miniature markers;
Ø No pollution to the environment;
Ø Easy to operate, high security features;
Ø Strong product traceability;
Ø Can achieve high-speed automation mark;
Ø Production costs are much lower than traditional ink printing.
Purpose of application Laser Powder
Laser powder is an indispensable additive when laser marking of plastic products cannot be mark or marking unclear, It can make the mark clear, beautiful, strong and durable, will not fade due to physical or chemical factors.
Laser Powder Application Scope:
Security seals, livestock ear tags, light switch covers, cosmetic packaging materials, automotive interior buttons and door handles, instrument panels, ABS keyboards for commercial machines, HDPE, ie, PET and PVC rigid containers and closures, nylon and PBT cars and Non-automotive electrical connectors, hood components such as fuse boxes and air caps, security labels, container locks, stationery, appliance housings, etc.
Laser Powder Characteristic:
a. Absorb laser energy, convert the laser beam into heat energy, heat the plastic, carbonize, evaporate and chemically react. For different chemical plastics, there are different varieties of light-colored laser markings on dark backgrounds and dark-colored laser markings on light-colored backgrounds.
b. Suitable for marking PP,ABS,PE,PA6,PA66,PS,PBT,PET,PVC,POM,SEBS,TPU,TPE, White lettering can be marked on black plastic products.
c. It can make laser marking/coding on the plastic surface more smooth & clear
d. Can be directly mixed with existing toner and formula
e. There is no significant impact on the properties of the material;
f. Its lower addition makes the use cost lower;
g. Suitable for different types of laser coders.
h. Save on material costs and minimize your scrap rate;
i. High marking speed, active ingredient has very strong laser sensitivity and significant color change effect
j. Superior resolution and contrast, laser-active microspheres can be well distributed in a fine range
Laser Powder Apply for Laser Marking System
It is suitable for laser marking system with wavelength355-1064nm and 1064μm.
