Laser Labeling
Laser labeling is the process of using a laser marking machine to put a label on a product. The label can be used for traceability, identification, or adding regulatory information. Replacing a labeler with a laser can have benefits across many aspects of production.
Using a laser marking machine rather than a standard inkjet printer for labeling will improve value with time, money, and production. Laser markers decrease production time, increase permanency of labels, and decrease use of extra materials.
Below, we will discuss the differences between laser marking and standard labeling, the characteristics of each, and the best machines to use.
Laser Labeling Machine
KEYENCE offers a UV laser marking machine that marks high-contrast, damage-free, clear labels. To ensure ease of use, this UV laser marking machine contains easy-to-use software that controls the marking. The software can be programmed based on font, size, contrast, materials, and more, depending on your specific requirements.
3-Axis UV Laser Marker MD-U Series
The UV Laser MD-U Series is the world’s first 3-Axis Control UV laser. It uses a UV laser and 3-Axis Control to mark a variety of shapes, sizes, and materials. The 3-Axis Control marks uniformly and without distortion. It achieves this by using an edge-to-edge laser uniform line width rather than cylindrical lines.
Due to the dramatically shortened wavelength, the MD-U’s beam can be absorbed by even the most highly heat resistant materials. It marks with high contrast and permanent marks that do not fade over time. It leaves a clean mark that aesthetically prints any label needed. The MD-U can be used across industries and various needs. It automatically adapts, even with a surface with multiple materials, such as PCBs, battery packs, and lighting equipment.
Labeling and Laser Marking Characteristics
Laser markers operate differently than standard labeling systems. Ink labeling systems need extra materials to minimise damage to the product and get an intense mark. These extra materials are usually ink ribbons or thermal heads. Because of the precision of a laser, labeling with a laser marker only requires a UV laser machine.
UV lasers work by passing a standard wavelength through two crystals, which creates a thin laser with high absorption. The high absorption is not synonymous with high heat, a UV laser is gentle on materials and can independently mark without needing protective materials. Because of the high absorption rate, the marks are permanent and do not fade over time.
Inkjet labeling machines were standard, but new laser marking technology outperforms these machines.
