How Does 3d Laser Marking Machine Process Work On Metals - China

Fiber laser marking machines are one of the modern innovations in the manufacturing industry.

Fiber laser marking system prevents high costs as a result of providing more efficiency compared to other marking methods.

It is preferred because of the need for regular maintenance and consumables.

Advantages of 3d laser marking machine use are not limited to these.

The range of materials that can be applied is also greater than the machines of other marking methods.

Its working life is also longer than other machines.

Laser marking of metals

Since ancient humans discovered the ability to shape metals, we’ve been marking them, whether for artistry, personalization, or traceability.

Metals are complex, conductive, reactive, and can form alloys with chemicals.

When you are looking for a laser marking machine for metal, the type of metal to be machined determines the best solution.

Laser marking

Laser engraving

In the laser engraving process, laser equipment is used to melt and evaporate the surface material of the workpiece.

In this way, the laser beam removes part of the material.

The graphics left on the surface are engraved words.

Clear

During the removal process, the laser removes the top layer material from the substrate.

There is a sharp contrast due to the different colors between the top layer and the bottom plate.

Common materials removed by laser marking include anodized aluminum, coated metals, foils and films, or laminates.

Annealing marking

Annealing marking is a special method suitable for laser etching metals.

The thermal effects of the laser can form oxidation beneath the surface of the material, causing a change in the color of the metal surface.

Surface Etching

The laser etching process involves using laser light to alter the surface finish of the metal and create contrast by enhancing the way it reflects ambient light.

The depth of penetration usually does not exceed 0.01 mm.

Laser etching is probably the most widely used high-speed laser marking process.

Color markers on ferrous metal and titanium

Laser color marking of stainless steel and titanium is a well-known marking technology, but its popularity in the industry is still limited.

Like laser annealing, laser color marking is also based on surface oxidation.

Changing different laser parameters will result in different oxidized coatings, allowing users to see different colors.

Black markings on anodized aluminum

So-called “black marking” is a technique widely used by mobile device manufacturers to mark trademarks and serial numbers on anodized aluminum casings with high contrast, a pleasing look and feel, and no damage to the protective oxide layer.

With the ability to operate in short pulses, and a high degree of control over energy and peak power, fiber lasers are the best choice for combining a true black appearance with the benefits of laser marking without destroying the corrosive properties of the coating material.

3d laser marking machine is the most accepted technology among the laser marking systems due to its versatility, minimal maintenance and nil requirement of consumables.

Unlike Co2, it uses optical fiber doped with rare earth element as a laser source and can mark with much more intensity comparatively.

It provides best industrial solution for product identification and traceability.
