What precisely is laser marking? Well, Laserowe Znakowanie is a non-contact printing process with advantages over other technologies, including high-quality marking, durability, and low consumable costs. Videojet’s laser marking system portfolio comprises CO 2, fiber, and YAG lasers in a range of strengths for marking a wide range of materials in a range of applications. Videojet also provides a variety of laser accessories, including lenses and beam rotation devices, to help with line integration and laser performance.
What are the benefits of laser marking?
Industrial marking lasers from Videojet are among the most efficient on the market. Ordinary industrial markers (dot peen – needle) are significantly faster at making a precise impression (engraving).
CO2 lasers, fiber lasers, UV lasers, and YAG lasers are the four marking lasers. They are part of a larger category of items called “industrial marking machines,” “laser marking machines,” or “marking machines.”
Videojet laser marking equipment is tailored to your specific production line or marking station. The modular construction simplifies integration, and the information transmission possibilities make printing process control easier.
All safety criteria are met by Videojet laser systems, assuring safe operation and comprehensive service care from certified professionals. Laser marking is a safe and effective option that can help your company flourish.
What kind of materials may be laser marked?
Stainless steel, aluminum, gold, silver, titanium, bronze, platinum, and copper are all metals.
ABS, polycarbonate, polyamide, PMM, and polymers with additives are examples of plastics.
Packaging and foils.
Laminates.
Depending on the material, several types of lasers (fiber lasers and CO2 lasers) are utilized for laser marking.
Many businesses utilize laser marking to permanently write text on many sorts of materials, such as branding, labeling, and product numbering.
There are several lasers marking procedures.
Explanation of the various laser marking processes’ properties
Annealing marking is a type of laser marking that is used on metals. Oxidation happens due to the influence of the laser beam’s heat on the material’s surface, resulting in a color change on the material’s surface. The surface’s exterior structure remains unaffected, and the resultant marking is clear and visible.
This laser marking technique is mainly utilized on dark polymers. The laser beam dissolves the substance during foaming. During the process, gas bubbles develop in the material, causing it to reflect light diffusely. As a result, the marking stands out from the remainder of the unmarked space.
The action of heat in the substance causes a chemical reaction. Different hues are obtained depending on the material’s composition. For example, if a lighter material discolors during laser marking, soot particles are released, which causes the darker marking.
The laser beam also removes material. The resulting depression on the material’s surface is called. During laser engraving, the material’s surface is melted and evaporated by the laser.
More details about laser engraving
The laser beam eliminates the surface layers that have been formed on the base material during firing. The color contrasts between the top and bottom layers generate contrast. Anodized aluminum, coated metals, films, and laminates are the most common materials laser-marked utilizing the baking approach.
