What Materials Can Be Marked with a UV Laser Machine?

For materials like metals, plastics, and glass, the 3-Axis UV Laser Marker MD-U Series is a great option for versatility. The MD-U Series generates detailed, damage-free, and high-contrast marking on a range of shapes, materials, and sizes. Additionally, the MD-U Series creates neat plastic cuts without heat effects, burrs, and yellow tinting.

Unlike a conventional laser cylindrical target, the MD-U Series has a 3-Axis control that creates distortion-free marking. The 3-Axis control uses a uniform line width across a marking area of 300 mm x 300 mm. Because of this, all characters will have the same shape and thickness from edge to edge. Additionally, the 3-Axis system has software that de-focuses each target to eliminate mismarking and distortion.

The MD-U 3-Axis also understands a variety of targets, including 3D stepped, inclines, cylindrical, and cone targets. Even if a target does not fit into those shape categories perfectly, you can upload the profile of the target into MD-U&#;s Marking Builder 3. The MD-U will understand the profile and mark it appropriately without distortion. This is beneficial for objects like tablets, tubes, earbuds, and other odd-shaped parts.

The MD-U can create many markings such as:

Manufacturers across the globe use UV laser marking due to its precision and ability to work on sensitive materials. The shorter wavelength (often 355 nm) allows UV lasers to create detailed, high-contrast marks on materials like plastics, ceramics, and glass without causing heat damage. Using a UV laser marking machine allows for minimal material alteration, which is especially important for marking items like microchips or delicate medical devices.

UV laser markers are the best option for marking materials that reflect longer wavelengths when compared to other laser technologies. They excel at creating clear, high-contrast marks on transparent or highly reflective surfaces. In contrast, other lasers, such as infrared or CO2, struggle to achieve the same level of precision without causing damage.

The precision offered by UV laser technology also ensures that barcodes, logos, and detailed product information can be clearly marked, even on the smallest components. One final reason UV lasers are often chosen is that they operate at higher speeds. Production efficiency, while maintaining the quality and durability of the markings, is easier to achieve.
