Laser technology has come a long way since the introduction of the first laser in 1960. Nowadays, it is considered one of the best marking solutions for engraving metals, as it provides high-contrast, high-quality identifiers in all types of production lines.
Each marking technology has its benefits and drawbacks. Between dot peening, inkjet printing, laser marking, and printed labels, the right solution is not always obvious. The key to choosing the best technology is to understand your marking requirements.
Manufacturers who need permanent markings for traceability typically have two options: dot peen marking or laser marking. Between these two technologies, the choice is not always easy.
Every capital investment is a huge decision, and buying a laser marking machine is no exception. Despite the high initial cost, the investment is worth every penny for a growing number of manufacturers.
Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.
If you are relatively new to laser technology, you are probably wondering what’s the difference between laser engraving and laser etching. And more importantly, which one is right for you.
Deep laser engraving is a process that uses a highly focused beam of light to engrave 3D forms into metals. Pulsed fiber lasers are the best tools for deep engraving because they reach the high peak power needed to carve metal surfaces.
Laser ablation occurs when a laser beam removes material from a localized area. Used in various industrial applications, this process can create permanent marks (laser marking), remove contaminants and coatings from surfaces (laser cleaning), modify a part’s roughness (laser texturing), cut through a surface (laser cutting) and much more.
