How does Metal Engraving Work?

LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. Laser beams are created by stimulating an atom until it releases particles of light. This light energy is measured in nanometers or wavelength - higher wavelengths result in more powerful beams. With the help of engraver machines, we can harness this concentrated light and direct it to cut or mark an area.

A laser engraver can cut, engrave, or mark several materials such as coated metals, rubber, plastic, wood, and leather. If you want to engrave metals, a fiber laser engraver delivers exceptional performance. However, avoid using a fiber laser engraver for organic materials like leather and wood. While these materials are not transparent to us, they remain transparent to the 1062nm wavelength of the fiber laser beam. Although it’s possible to leave marks on organic materials such as leather, glass, or wood with a fiber laser, that’s not what the device is best suited for.

The unique process heats up the target area and leads to oxidization, causing a color change beneath the material’s surface, leaving a permanent mark.

Why Choose Fiber Laser Engravers?

Hobbyists, crafters, small businesses, and various industries use fiber laser engravers for marking products and accessories with text or graphics. You can use fiber laser engravers for marking parts or serial numbers, ID codes, barcodes, and graphics.

Laser marking is a permanent process that creates a lasting mark on metal. A beam of concentration from a fiber laser engraver interacts with the metal’s surface, and it changes the metal’s appearance and properties. Since the concentrated beam targets a specified area, the fiber laser engraver successfully creates high-quality and precise marks on the surface. Hence, fiber laser-engraving machines are the top choices for applications where you require permanency and accuracy.

For instance, a UV laser marker offers a wavelength of around 355NM. This low power is ideal for marking plastic and glass, both of which are heat-sensitive materials. Since UV laser markers emit less energy, they are ideally used for marking soft and organic products. However, fiber lasers function at 1070NM and deliver higher power for engraving more rigid materials such as metals or hard plastics.

Fiber Laser Engravers for Engraving Metals

Fiber Laser Marking Machines or Fiber laser engravers are innovative tools for marking metals. Although you can mark metal with a CO2 laser engraver by applying a laser bond spray, fiber laser engravers remain the best technical tools for metal marking applications and can fill your creative minds with many project ideas. These hi-tech accessories are ideal for accurate engraving/marking results and can also cut through alloys or painted metals.

Benefits of Fiber Laser Engraving

To further your understanding of how to engrave metal, you must learn the several benefits that fiber laser marking has over other engraving methods. One of the advantages is that the process is ideal for producing high-precision markings on metals. If you want to engrave complex graphics, numbers, and barcodes, fiber laser engravers can make easy work of small-scale shapes and digits. For instance, if you’re going to create engraved metal tags for nameplates, number plates, or any accessory, fiber engravers are the top choice.

Another benefit is that fiber laser engravers offer a non-contact process, which means the laser beam does not physically touch the material and relies on heat to achieve the desired results.

Users can also optimize their workflow productivity because fiber laser engravers offer exceptional efficiency at reduced costs. By taking the applications and metals into account, you can adjust the laser source power and other features for enhancing the marking performance. The entire laser marking process with a fiber laser engraver is environmentally friendly, and you can easily control it from your computer.

Another incredible benefit is that a single laser setup can come in handy for multiple processes. For instance, a single setup can switch between laser engraving and marking methods, both of which are incredibly similar. The functionality saves time and reduces high costs.

Almost any fiber laser engraver for metal creates a serious laser hazard that can cause severe eye injuries and even complete vision loss. Never overlook the importance of wearing appropriate protective gear to shield your eyes from the fiber beam. A small mistake can result in vision loss. Whether you are engraving metals or hard plastics, you must wear protective gear such as laser safety glasses. These special goggles block out portions of laser light to protect the retina. These glasses work the same as those for other laser systems, but make sure you choose a pair with the desired optical density to attenuate the beam.
