Durable! 355nm UV nanosecond laser marking ear thermometer shell

In the post-epidemic era, infrared body temperature measurement tools such as ear thermometers and forehead thermometers have made up for the shortcomings of mercury thermometers because of their good portability, immediacy, and avoidance of cross-infection. A must-have for temperature measurement at home.

Based on the needs of epidemic prevention and control, temperature measurement tools such as ear thermometers and forehead thermometers are frequently used on a daily basis. Repeated grasping and erosion by sweat can easily cause the inkjet or label paper on the surface to fall off or become blurred. Consumption The senses and experience are poor.

The permanent marking solution brought by laser marking changes the shortcomings of label paper or ink marking, and makes the marked number, logo, model and other information clearer, with high contrast, and is permanently non-erasable and will not fade and fall off.

Laser marking, in short, uses a high-energy-density laser beam on the outer layer of an object to vaporize or change the color of the surface material, thereby leaving a mark, and has a wide range of applications. The mainstream ear thermometer and forehead thermometer shells are mainly made of medical grade ABS material, which is an extremely versatile thermoplastic engineering plastic with good creep resistance and easy processing. It is currently one of the largest and most widely used polymers. one.

According to the characteristics of ABS material polymer being sensitive to heat, the 355nm UV nanosecond laser has low power (5W), short pulse width (about 25ns), short wavelength, high material absorption rate, and has the characteristics of "cold" processing and low degree of thermal action. The heat affected zone is small, which can avoid carbonization or melting during marking.

At the same time, the beam quality of the laser is high (M2<1.2), the diameter of the spot after focusing is very small, the marking line width is micron level, complex graphics and texts can also be marked, and the edges are smooth and the resolution is high. It is a high-quality marking and visual effect. Well, there is no need to worry about tampering, the anti-counterfeiting effect has been improved in all aspects, enabling ear thermometers, forehead thermometers and other temperature measurement tools to have a higher brand value.
