How Lasers Engrave Metal?

Deep Engraving

Laser Deep Engraved Metal

Laser deep engraving machine adopts advanced optical fiber resonance technology to effectively improve the power density and beam quality of the laser, so that the laser can quickly sublimate the metal material into a gas in a short time and reduce the heat-affected range. The frame or outline is more vertical, and the burrs are effectively reduced, and the texture of the bottom surface is clear and beautiful. Typically the laser engraves the metal in multiple layers in shifts to achieve the desired depth.

Laser deep metal engraver is used to make molds, wheels, automobiles, reliefs, seals, badges, logos, jewelry with carbon steel, stainless steel, aluminum, copper, brass, zinc, nickel, and high-strength steel.

Black Engraving

Laser Black Engraved Metal

When laser engraving metals, oxides of contrasting colors are formed due to the interaction of the molten substrate with oxygen in the air. Most very rough surfaces absorb a lot of light so the markings usually appear black or, depending on the material, dark gray (aluminum) or dark brown (steel, brass, copper).

White Engraving

Laser White Engraved Metal

For white engravings, the surface should be structured so that the material melts only slightly. This results in a smooth, highly reflective surface - which would appear as a white mark in the case of materials such as galvanized steel. Due to the low immersion depth, the coating remains intact and corrosion-resistant. Especially with dark metals such as hardened steel, high-contrast white engravings have proven their advantages. The combination of black and white engravings is especially suitable for the application of two-dimensional codes. This increases contrast and improves QR code quality and readability.

Color Engraving

Laser Color Engraved Metal

Color laser metal engraving machine is a marking tool that uses MOPA fiber laser generator to print color patterns on stainless steel and titanium surfaces. The key to realizing the colorization of the metal surface is to strictly control the pulse energy and pulse width of the laser. Lasers with high frequency and low pulse energy are more suitable for this application, and fiber lasers are the most suitable choice due to their adjustable pulse parameters and good beam quality. By strictly controlling the injection of heat, different degrees of oxide films are formed on the metal surface, and light interference occurs when light is reflected, resulting in different colors. The color engraving on the metal surface changes in the following color order: orange-red-purple-blue-green-blue-blue-green-green-yellow-green-yellow-orange-red.

3D Engraving

3D Laser Engraved Metal

3D laser metal engraver is a fiber laser marking machine that uses high-precision three-dimensional positioning and marking system, high-speed digital three-axis dynamic focusing and scanning system to realize three-dimensional multi-curved surface and large-format marking. The 3D laser metal engraving machine can perform various 3D marking modes such as inclined planes, step differences, cylinders, cones, spherical surfaces, and stretched curved surfaces.

Compared with traditional 2D engraving, 3D engraving has greatly reduced the surface flatness requirements of the processing object, and the processing effect is more colorful, and more creative processing technology came into being.

3D fiber laser metal engraver usually used in mobile phone manufacturing, precision molds, three-dimensional circuits, molds, 3C electronics, auto parts, electronic communications and other industries. Refined surface marking provides a professional solution for today's metal surface treatment.

Rotary Engraving

Rotary Laser Engraved Metal

Rotary laser engraver is an automatic engraving tool with a rotating attachment added to the ordinary laser marking machine to engrave on the arc-shaped parts. It uses synchronous tracking for rotary engraving. With the control of the computer, one axis of the motor inside the vibrating mirror rotates, and the other axis remains stationary, and cooperates with the rotation of the motor to complete the engravings of arc-shaped, ring-shaped and cylindrical metal parts.

Rotary laser metal engraving machine is used to personalize YETI mugs, cups, tumblers, ramblers, cans, rings, bracelets, necklaces, pens, gun barrels and cylinders.

Pros and Cons

Laser engraving is a non-contact process without any pre/post processing.

Thanks to the flexible choice of pulse frequency and pulse duration, each laser-engraved pattern can be individually adjusted to any material and to any desired quality.

High speed, high contrast, high quality, high precision, and environmental protection without consumables.

Laser-engraved marks are permanent and highly traceable.

Laser engraving features with a high repetition rate and therefore short cycle times, so laser engraving is a faster process than temper marking despite the greater depth into the material.

Thanks to the grooves formed in the material during laser engraving, the markings are extra robust against external influences.

Due to the targeted control of the laser power, engraving results are always precisely repeatable.

The metal surface is barely affected by the marking process and remains smooth even after marking.

The laser beam emitted by the laser machine has almost no radiation hazard, but there will be ionizing radiation and stimulated radiation during the engraving process, it is best to stay away from the beam. This induced radiation is damaging to the eyes. Protective measures such as wearing laser safety glasses should be taken as far as possible for close-range operations.

So far, you should have understood all the things to consider when you learn, buy and use a laser engraver for metal. If you still have any questions, don't hesitate to contact us to continue a more in-depth discussion.
