#ENGRAVING LASER HOW TO#

Unless the color of the base material is pale enough to generate a high contrast, this method isn’t recommended.īecause the second (and longer) engraving method engraves both black and white marks, the contrast is higher. In the first (and faster) engraving method, the bare material contrasts the black marks that are engraved. When you laser engraves a surface, there are two ways to create contrast. Is it Possible to Engrave Marks With High-Contrast and High-Quality?īecause of the deep crevices that laser engraving creates, permanent marks are darker (engraving depth can reach 0.5 mm).

Ask an expert for guidance if you need it.

You can find specific information about the metal you’ll be marking by scrolling through the list of metals.

Check out our integrated laser machines page for turnkey automated and semi-automated laser solutions.

CO2 lasers and fiber lasers cover our range of laser marking systems.

Our OEM marking systems include a variety of lasers for industrial applications that can be integrated by yourself or with an integrator.

You can use the list below to find the right laser engraving machine for your needs:

In order to protect your work environment and the laser’s lens, laser systems should always come with a fume extraction system.īecause fiber lasers produce a wavelength that reacts well with metals, they make ideal engraving tools. Laser engravers are pretty powerful machines considering the extreme temperatures required for sublimation.Īs soon as materials reach this temperature, they vaporize into fumes. Therefore, the surface instantly becomes a gas and never becomes a liquid by absorbing enough energy.Ī laser engraving system that produces enough energy must reach the vaporization temperature of the material within milliseconds in order to achieve sublimation. Laser etching changes the surface of a material by melting it laser engraving changes the surface by sublimating it. Laser etching, on the other hand, is often preferred if engraving the most resistant identifiers isn’t needed since it’s a high-speed process that relies less on ablation. Traceability issues may be addressed by shot blasting, e-coating, or heat treatments. A metal engraving machine can work with steel and aluminum (including anodized and die-cast aluminum).Ī major benefit of this process is that it can engrave 2D codes that retain high readability rates after post-processing. Metal workpieces that are subjected to various types of wear and surface treatments are usually engraved with laser technology.

Compatibility of the marking method with the material being marked.

It is the laser marking speed that prevents bottlenecks in production.

Resistant to harsh conditions: its ability to remain legible.

You should consider three factors when selecting a laser marking process: Which is Better: Laser Engraving or Laser Etching?

The purpose of this article is to provide in-depth information about laser engraving and how to find a laser engraving machine.

Lasers produce high temperatures required for vaporization when they strike localized regions with massive amounts of energy. By removing layers from the surface of the material, the laser beam acts as a chisel, cutting markings. How does laser engraving work and what is it?Ī laser engraves permanent, deep marks by vaporizing materials into fumes.
