High power solid state UV laser facilitates anti-counterfeiting traceability of masks and forehead thermometers

 

Since the outbreak of the epidemic, masks and forehead thermometers have become necessities of life at this stage. However, the huge demand gap has made some unscrupulous traders take advantage of it, and a large number of inferior masks have entered the market. Fake masks not only have no protective effect, but also have the risk of contamination due to substandard production environment hygiene, which is extremely harmful to personal health. To identify real and fake masks, the most direct way is to check the laser anti-counterfeiting marks.

 

First of all, the pharmaceutical and medical industries attach great importance to safety and hygiene, so the requirements for product marking are very high, and information such as production date, instructions for use and other information must be permanent, so we will choose laser marking machine as the processing mark, and Non-jet printer, silk screen printing and other traditional methods.

 

Forehead temperature guns generally print LOGO on the plastic shell. The effect of laser engraving by UV laser marking machine has no feel, and the font will not turn yellow due to scorching, which can reflect the grade of the brand, and the price of UV laser marking machine Compared with the fiber laser marking machine, it is higher, so it can reduce the probability of being counterfeited and play an anti-counterfeiting role.

For boxed 3M N95/KN95 series masks, it can be identified by the anti-counterfeiting label on the mask box. The labels of real masks will change color from different angles, while the labels of fake masks will not change color. For bulk 3M N95/KN95 series masks, the authenticity can be identified by observing the fonts on the masks. The real 3M mask text is marked by laser, and the font has twill, while the fake is printed by ink and has dots (traces of uneven ink).

Why laser: the characteristics and application advantages of laser marking anti-counterfeiting

 

The basic principle of laser marking is to use a high-energy-density laser beam to act on the surface of the material, to instantly vaporize or change the color of the surface material by focusing, and to form the required permanent image by controlling the path of the laser on the surface of the material. Text mark. Since laser marking can print various characters, symbols and patterns, the size of the characters can be from millimeters to micrometers, which has special significance for the anti-counterfeiting of products, so it is widely used in the anti-counterfeiting market.

 

Before the large-scale application of laser marking, the marking on packaging was usually printed with ink. The marks printed by this traditional method tend to peel off over time, become blurred, easily tampered with, and cannot be used with high precision. Although it has advantages in equipment cost, the continuous cost of consumables (ink) is high, and it will cause some pollution to the environment.

Taking the most common food packaging as an example, because the marks printed by traditional methods are easy to erase and fall off, some criminals will print some expired or even counterfeit products with brand trademarks, or modify the production date to make these substandard products. circulated in the city. Such phenomena are common in the fields of grain and oil, beverages, snacks, sauces and so on. In addition, for some paper food packaging, the harmful substances of ink may penetrate the packaging and contaminate the food, posing a threat to the health of consumers.

 

The emergence of laser technology has solved a series of problems brought by traditional ink printing. For food packaging, the use of laser marking has the advantages of non-toxic, non-polluting, high efficiency, high definition, exquisite patterns, and never falling off. In addition, laser marking can also be combined with computer technology, and by linking to the database system, we can track and query the detailed information of the factory and circulation of food in time to ensure that we can eat with confidence.

 

의료 산업은 레이저 마킹의 호위와 불가분의 관계가 있습니다. 의료제품은 인체와 직접적으로 접촉하는 만큼 국민의 생명과 건강과 직결되기 때문에 의료제품의 위조방지 및 위조방지는 소비자의 건강과 안전을 지키는 최우선 과제가 되었습니다.

위에서 언급한 일부 특성 외에도 의료 기기 및 의약품 표시에는 몇 가지 특별한 요구 사항이 있습니다. 예를 들어 일반적인 알약과 연질 캡슐의 경우 석판 인쇄를 사용하면 제품에 스트레스가 가해지는 반면 비접촉 레이저 마킹은 캡슐을 변형시키지 않고 작은 알약에 더 작은 정보를 표시할 수 있습니다. 스테인리스 스틸 외과 및 치과 장비와 같은 의료 기기에서 레이저는 박테리아가 표면에 달라붙는 것을 방지하는 절대적으로 매끄러운 표면을 표시할 수 있으며 표시된 표면은 부식 방지 화학 부동태 처리를 손상시키지 않으므로 부식 방지 코팅이 가능합니다. 수년간의 사용과 수많은 세척 및 살균 후에도 지속됩니다. 또 다른 예는 처음에 언급한 3M 마스크,

 

실제로 레이저 마킹 위조 방지 기술은 마스크의 진위 여부를 식별하는 데 사용할 수 있을 뿐만 아니라 식품, 의약품, 담배, 미용 및 전자 제품 분야에서 포장 위조 방지 및 추적에 큰 역할을 합니다. 레이저 마킹 위조 방지는 우리 삶의 모든 측면에 통합되었다고 말할 수 있습니다.
