Industrial 355nm UV Laser Marking of Plastics
Apr 13 , 2023Industrial 355nm UV Laser Marking of Plastics
Plastics laser marking provides numerous advantages and benefits. Laser marking plastics is a noncontact digital process in which information and graphics are indelible applied onto a plastic surface with minimal material penetration. Breakthrough laser additives blended into plastics produces superior laser marking contrast for use with laser sources NIR wavelength 1060-1080nm Ytterbium fiber, Vanadate, frequency-doubled 532nm Green and UV laser 355nm . The laser process terms “laser marking”, “laser etching”, “laser engraving” are often interchanged, however the technical aspects have important distinctions. Degree of depth is the primary distinguishing factor.
Laser Marking Mechanisms
For plastics laser marking, the mechanism is to irradiate the polymer with a high-energy radiation source, e.g., Ytterbium fiber laser. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. For plastics laser marking operating in the Near-infrared spectrum there are three types of surface reactions: 1) Carbonization or charring, 2) Chemical change and 3) Color change. The same laser can accomplish all surface reactions by changing settings (power, pulse repetition rate, marking speed) within the laser marking software.
Today,we will recommend you RFH UV laser brand from China.
RFH UV Laser Marking Module used for paint stripping on plastic
To meet the market demand, RFH newly developed S9 series UV laser in 2020. Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved
