When talking about laser marking on metal materials, fiber laser is always the only option?
No, you don’t need a fiber laser to achieve great quality marks on metal, a CO2 laser can also do the job.
Actually, CO2 laser can directly mark a variety of coated metals such as anodized aluminum or powder coated stainless steel.
But we all know, bare metals reflect the wavelength of a CO2 laser, so how?
Let’s introduce you to a great option: Metal Marking Spray.
Bare metals like stainless steel, titanium, or nickel plating can be pre-treated with a laser metal marking spray prior to engraving with a CO2 laser.
The pre-treatment process of laser metal marking spray is very simple and while it will not actually remove any of the metal material, but it will be left with a durable and permanent mark on the bare metal material surface.
Just simply spray your material with laser metal marking spray evenly, engrave and wipe off the excess to enable the CO2 laser to easily engrave on metals with a dark black or silver finish. You can buy laser metal marking spray products from your local markets.
Using a laser metal marking spray allows laser owners to perform almost all kinds of exciting applications, such as customizing jewelry and accessories, personalizing stainless steel flask and phones, identification tags and barcodes, or even serializing metal components.
