Ultraviolet laser marking machine helps the anti-counterfeiting traceability of masks and forehead guns

Since the outbreak, masks and forehead thermometers have become necessities of life at this stage.

However, the huge demand gap has caused some illegal vendors to take advantage of it, and a large number of inferior masks have flowed into the market. Terms related to 'fake masks' and 'mask fraud' have repeatedly appeared in hot searches.

Fake masks not only have no protective effect, but they are even at risk of being contaminated because the production environment is not up to standard, which is extremely harmful to personal health.

The most direct way to identify genuine and fake masks is to check the laser anti-counterfeiting marks.

　　 First of all, the pharmaceutical and medical industries attach great importance to safety and health, so the requirements for product marking are very high, and information such as production date and instructions for use must be permanent, so we will Choose a laser marking machine as the processing mark, rather than traditional methods such as cij printers and silk screen printing.

Forehead temperature guns usually print LOGO on the plastic shell. The effect of laser engraving by the UV laser marking machine is not hand-feeling, and the font will not be yellow due to burnt, which can reflect the grade of the brand, and the UV laser The price of the marking machine is higher than that of the fiber laser marking machine, so it can reduce the chance of being counterfeited and play a role in anti-counterfeiting.

　　 is for boxed 3MN95/KN95 series masks, which can be identified by the anti-counterfeiting label on the mask box.

The label of the real mask will change color from different angles, while the label of the fake mask will not change color.

For the 3MN95/KN95 series masks in bulk, the authenticity can be distinguished by observing the font on the mask.

The real 3M mask text is marked by laser, the font has diagonal lines, while the fake is printed by ink with dots (marks of uneven ink).

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

　　The basic principle of laser marking is to use high energy density laser beam to act on the material On the surface, the surface material is instantly vaporized or the color is changed by focusing, and the required permanent graphic mark can be formed by controlling the path of the laser on the surface of the material.

Because laser marking can produce a variety of characters, symbols and patterns, and the size of characters can range from millimeters to micrometers. This has special significance for the anti-counterfeiting of products, so it has a wide range of applications in the anti-counterfeiting market.

　　Before the large-scale application of laser marking, the marking on the package was usually printed with ink.

The marks printed by this traditional method are easy to fall off and blur over time, are easy to be tampered with, and cannot perform high-precision operations.

Although it has advantages in equipment cost, the continuous cost of consumables (ink) is high, and it will cause certain pollution to the environment.

Take 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 fake products with brand trademarks, or modify the production date to make These substandard products are circulating in the market.

Such phenomena are widespread in grain and oil, beverages, snacks, sauces and other fields.

In addition, for some paper food packaging, harmful substances in ink may also 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 caused 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. Through the link to the database system, we can track and query the detailed information of food delivery and circulation in time to ensure that we can eat with confidence.

The medical industry is inseparable from the escort of laser marking.

Because medical products are in direct contact with the human body and are related to the lives and health of the people, the anti-counterfeiting and anti-counterfeiting of medical products has become the top priority of protecting the health and safety of consumers.

In addition to the features mentioned above, the marking of 　　 medical devices and drugs also has some special requirements.

For example, common pills and soft capsules, if lithographic printing is used, it will produce pressure on the product, and non-contact laser marking will not deform the capsule, and can mark more minute information on the tiny pills. .

On the medical equipment represented by stainless steel surgery and dental equipment, the laser can mark the absolutely smooth surface, which can prevent bacteria from sticking to the surface, and the marked surface will not damage the corrosion-resistant Chemical passivation treatment allows the anti-corrosion coating to exist even after years of use and countless times of cleaning and disinfection.

For the 3M mask mentioned at the beginning, whether there is a laser mark is an important sign to distinguish between authenticity and fake.

　　 In fact, laser marking anti-counterfeiting technology can not only be used to identify the authenticity of masks, but also in packaging anti-counterfeiting and traceability in the fields of food, medicine, tobacco, beauty cosmetics, and electronic products. It also plays a huge role. It can be said that laser marking anti-counterfeiting has been integrated into all aspects of our lives.
