RFH 355nm UV laser marking mask date without carbonization
Mask marking: RFH 355nm ultraviolet laser, fast speed and high precision
Mask date marking, need to use UV laser cold light source
RFH has been working for 13 years. The 355nm UV laser specially designed for mask marking has fast speed, high accuracy and high stability. It is a dark horse in the plastic marking industry and should not be missed.
For medical masks and civilian masks, we can first distinguish them from the outer packaging of the masks.
Take a look at the product name. The product name on the outer packaging of medical masks must have the word "medical".
Second, look at the product registration certificate number. Medical masks must have the four words "X-Mechanical Injection Standard". For example, medical masks produced in Henan Province all carry the four words "Yu-Mechanical Injection Standard". These four words mean that the product is registered as a medical device, and there is no such number for civilian masks.
Third, look at product standards. Medical masks are divided into disposable medical masks, medical surgical masks, and medical protective masks. The industry standards are YY/T0969, YY0469, and GB19083. The medical protective masks of GB19083 have a high level of protection against viruses and bacteria and are suitable for anti-epidemics. Medical workers on the frontline.
Moreover, the outer packaging of many masks uses ultraviolet laser marking. The laser marking technology uses a laser beam to irradiate the processed workpiece, so that the irradiated area is oxidized to form a beautiful text or pattern. It can control the laser beam according to the calculator software system to realize the marking of the pattern on the object. For example, printing the production code, date and other product information on the packaging cannot be erased, nor can its shape be changed. Products processed by laser marking machines also have a high anti-counterfeiting function and are more traceable.
The UV online laser marking machine can use RFH's 3.0w-5.0w Expert II 355nm UV laser. The pulse width is short (<14ns@30K), the beam quality is superior (M2<1.2), and the spot characteristics are perfect (spot ellipticity>90%). It can maintain a consistent and stable quality under extreme industrial and scientific research conditions. Beam quality and high-efficiency power consumption characteristics. Therefore, even if the high-speed pipeline is continuously processed for a long time, there is no pressure, and the marking quality is still guaranteed.
Of course, in addition to the stable laser quality, the RFH 355nm UV laser is also very durable. We control from procurement-quality inspection before production-rigorous assembly process-finished product testing-warehousing quality inspection-inspection before delivery-after-sales service to ensure stable quality and consistency of equipment parameters with actual operating parameters. At the same time, there is also a professor and doctoral technical team that updates the function modules of the power control system in time, and improves the function modules according to the needs of the laser to ensure the long-term stable operation of the entire laser system.
After 12 years of hard work, RFH has won high recognition and a good reputation from users in all walks of life at home and abroad, and has established an excellent brand image in the nanosecond laser industry.
