El láser UV de estado sólido de alta potencia facilita la trazabilidad antifalsificación de mascarillas y termómetros frontales

Desde el estallido de la epidemia, las máscaras y los termómetros de frente se han convertido en necesidades de la vida en esta etapa. Sin embargo, la enorme brecha de la demanda ha hecho que algunos comerciantes sin escrúpulos se aprovechen de ella y una gran cantidad de máscaras inferiores han ingresado al mercado. Las máscaras falsas no solo no tienen efecto protector, sino que también tienen el riesgo de contaminación debido a la mala higiene del entorno de producción, lo que es extremadamente dañino para la salud personal. Para identificar máscaras reales y falsas, la forma más directa es verificar las marcas láser antifalsificación.

En primer lugar, las industrias farmacéutica y médica otorgan gran importancia a la seguridad y la higiene, por lo que los requisitos para el marcado de productos son muy altos, y la información como la fecha de producción, las instrucciones de uso y otra información debe ser permanente, por lo que elegiremos el marcado láser. Máquina como marca de procesamiento, e impresora sin chorro, serigrafía y otros métodos tradicionales.

Las pistolas de temperatura para la frente generalmente imprimen el LOGOTIPO en la carcasa de plástico. El efecto del grabado láser por la máquina de marcado láser UV no tiene sensación, y la fuente no se volverá amarilla debido a la abrasión, lo que puede reflejar el grado de la marca y el precio de la máquina de marcado láser UV en comparación con la máquina de marcado láser de fibra, es mayor, por lo que puede reducir la probabilidad de falsificación y desempeñar un papel antifalsificación.

Para las máscaras de la serie 3M N95/KN95 en caja, se puede identificar por la etiqueta antifalsificación en la caja de la máscara. Las etiquetas de las máscaras reales cambiarán de color desde diferentes ángulos, mientras que las etiquetas de las máscaras falsas no cambiarán de color. Para las máscaras de la serie 3M N95/KN95 a granel, la autenticidad se puede identificar observando las fuentes en las máscaras. El texto real de la máscara 3M está marcado con láser y la fuente tiene sarga, mientras que el falso está impreso con tinta y tiene puntos (rastros de tinta irregular).

Por qué láser: las características y ventajas de aplicación del marcado láser antifalsificación

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.

The medical industry is inseparable from the escort of laser marking. Since medical products are in direct contact with the human body, it is related to the life and health of the people, so the prevention of counterfeiting and anti-counterfeiting of medical products has become the top priority of protecting the health and safety of consumers.

In addition to some of the characteristics mentioned above, the marking of medical devices and drugs also has some special requirements. For example, for common pills and soft capsules, if lithographic printing is used, the product will be stressed, while non-contact laser marking will not deform the capsule, and can mark smaller information on tiny pills. On medical devices such as stainless steel surgical and dental equipment, the laser can mark absolutely smooth surfaces, which prevents bacteria from sticking to the surface, and the marked surface does not damage the corrosion-resistant chemical passivation treatment , allowing the anti-corrosion coating to persist even after years of use and countless cleanings and sterilizations. Another example is the 3M mask mentioned at the beginning, whether there is a laser mark is an important sign to distinguish the authenticity.

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