Hurry up! Let RFH this 355nm UV laser help you speed up food packaging information marking

Fast is the current development indicator for many industries, whether it is energy, chemistry, chemical engineering, machinery manufacturing, aerospace, or other industries. Kuai is full of pressure and challenges, because it will be accompanied by an indicator-good. Obviously, it is not easy to be fast and good. But it is not impossible, as long as it is intentional, it can be achieved. Below, RFH Laser Editor will introduce a fast and good laser manufacturing process:

Use RFH 355nm ultraviolet laser to mark information on food packaging, such as production date, manufacturer logo, and two-dimensional code.


So what kind of "fast and good" is it?


First of all, its working principle is to use high-energy-density laser to locally irradiate the workpiece, so that the surface material of the food packaging can instantly vaporize or undergo a chemical reaction of color change, thereby leaving a permanent mark, so the entire marking process is ultra-fast , It only takes 0.28 seconds to mark a thumb-sized QR code. Such ultraviolet lasers are particularly suitable for high-speed assembly line batch, automatic processing, production efficiency has risen linearly, and long-term production benefits are very considerable.


Then, it's good.

On the one hand, it is manifested in the marking effect: Everyone has seen a QR code, which is a small rectangular space with many small black and white pixel points (square dots, dots or other shapes). Pattern, such as the thumb-sized QR code mentioned above. The RFH 355nm UV laser can still be clearly marked because its marking beam is thinner: pulse width <14ns@30K, beam quality M2<1.2, strictly guaranteed in all frequency ranges, and the heat affected area is small.


On the other hand, in terms of long-term stable work, it can maintain a consistent and stable beam quality under extreme conditions in industry and scientific research. This is due to the technology it possesses: the internal cavity self-purification system, which maintains the cavity clean and guarantees the laser quality; the all-digital intelligent power control technology, updates the power control system function modules in time, and improves the function modules according to the laser requirements to ensure the complete set The laser system operates stably; the rigorous quality management system mechanism-from procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, level by level checks to ensure stable quality And equipment parameters are consistent with actual operating parameters.


This is the RFH 355nm ultraviolet laser that has won high recognition and good reputation from users in all walks of life at home and abroad. Are you using it? If you want to speed up food packaging information marking processing and improve production efficiency, this laser is your ideal choice.
