355 high-power UV laser marking food packaging production date
To mark the production date of food packaging, choose RFH 355nm UV laser
UV laser solves the safety problem of marking the production date of plastic packaging
Food is the top priority for the people, and food safety has always been a problem that plagues us. In the traditional process, ink jet printing is used to mark the production date of food packaging, but since the advent of laser technology, it has gradually replaced the ink jet printing process. Laser marking uses different laser sources according to industry applications. For example, fiber laser marking is used for metal surface marking, while 355-wavelength ultraviolet lasers are used for food plastic packaging materials.
The 355nm ultraviolet laser has a very small focus spot and a small processing heat-affected zone, so there is almost no damage caused by heat, so it is called a cold light source. Because of the extremely small heat-affected area of the UV laser, there is no thermal effect, and the deformation or scorching of the processed material is avoided.
Recently, a customer called for consultation and needed to mark the production date on the hot pot material packaging.
RFH recommended the Expert III 355 high-power ultraviolet laser for it. This model has three distinctive features: fast speed, high precision, and high stability, which can play an important role in identifying authenticity of signs.
In addition, the Expert III 355 high-power ultraviolet laser has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width <20ns@40k, small heat-affected area during processing, and perfect spot characteristics ( Spot ellipticity>90%).
Behind the outstanding performance, there is a stable and stable technology and manufacturing process support.
First of all, its R&D team is formed for RFH to introduce domestic and foreign professors, experts, and PhDs, and set up an application process R&D department, a laser R&D department, and an electrical R&D department to check. Its power control system-all-digital intelligent power control technology is independently developed by our R&D team. It can update the power control system function modules in time, and improve the function modules according to laser requirements (the power supply and the laser have a one-to-one correspondence. , The stability of the power control system determines whether the laser can maximize its performance during operation.) This is a solid backing for the stable operation of the entire laser system. In addition, it also has an internal cavity self-purification system, which makes the laser long life.
The second is the manufacturing process. Expert III 355 series ultraviolet lasers are manufactured in a rigorous manufacturing process. The entire process is produced in a dust-free workshop. The quality control department strictly controls the procurement, production, acceptance, and delivery of the whole machine. The power of the inspection equipment, the ellipticity of the spot, the beam direction, Only when the accuracy rate reaches 100% can be shipped to ensure the consistency of equipment operation under different environments.
Powerful and precise, practical and durable, is the comprehensive evaluation of the Expert III 355 series of ultraviolet lasers. With one product after another such as the Expert III 355 series of ultraviolet lasers, RFH has won high recognition and a good reputation from users in all walks of life at home and abroad. An excellent brand image has been established in the nanosecond laser industry.
