The laser marking machine, also regarded as a laser etching machine, is undoubtedly one of the best marking tools available. It can be applied to etch a wide range of materials and leave permanent marks on their surfaces. Laser marking technology produces high-quality and easy-to-read permanent marks which are reliable to manufacturers and customers. These marks are hardly damaged by these laser marking machines, even in extreme working conditions, such as vapors, high temperatures, etc. Compared with traditional marking methods, laser marking is a non-contact process along with lower operating costs and material costs. In addition, by means of a laser marker, some other useful information can be added to your products, including codes, serial numbers, and texts, etc.

So, what’s laser marking technology? Laser marking is a generic term. It stands for a collection of a broad range of surface processing techniques, such as printing, hot-branding, and laser bonding. In the working course of the laser marker, a focused beam of light will give permanent marks on the veneer of parts or materials. Plus, the marks won’t be worn away over the elapse of time.

Other than surface alternation, the laser marking technology also leads to the change in the color, which can be attributed to the chemical/molecular alteration, charring, foaming, melting, ablation, etc. The technique does not either involve the use of inks, or the use of tool bits which directly contact the surface of the material and abrades over time. The laser marking technology arguably holds an advantage over traditional engraving or marking technology, in which inks or tool bits have to be replaced regularly.

It’s important to note at the beginning that laser marking is a high-speed process of high precision. Laser marking works by means of a focused beam of light to give the mark on the material veneer. The light beam, essentially, is an atom that is stimulated to release particles of light. Contacting with the material’s surface, the beam will oxidize the laser marking area, bringing a change in the color.

Generally, the majority of markings will turn black. Moreover, laser marking also alters the material’s properties and appearance. The energy that is released is measured in wavelengths or nanometers ( NM ). The wavelength is proportional to the strength of the laser beam. In other words, the higher the wavelength, the more powerful the laser beam.

Laser marking technology is a way to permanently mark a product for branding, tracking, coding, personalizing, either for security or quality control reasons.

In this process, a strong laser beam will focus on the surface of the object and scan the focus point with the help of a moving scanning mirror to create an image. The laser source can deliver instantaneous high peak power on the target object, thereby instantly changing the surface of the object.

In this process, a strong laser beam will focus on the surface of the object and scan the focus point.

Laser marking does not use ink, solvent, acid, or other physical tools. These characteristics distinguish laser engraving from traditional engraving techniques.
Unlike traditional engraving methods, laser engraving will not cause material loss to the object during the operation. Laser engraving uses a laser beam to change the color of the surface of an object, thereby creating a clearly visible and indestructible mark without affecting the product.
Because this technology does not use ink, solvents or other consumables, laser marking has little impact on the environment. Most environmentally conscious companies tend to use laser marking solutions, which save costs and benefit the environment.

Now, let’s have a look at how laser marking actually works. Laser engraving machine creates easy-to-read marks by means of generating a visual contrast between the background and the text. Two methods help it do that readable marks: change color or specular reflection. Laser engraving machine not only can engrave, but also do etching, annealing, color change, and foaming.

Laser Engraving:

Laser engraving is a common method of utilizing lasers to engrave an object. The laser beam removes material from the surface and create an image at eye level. The laser beam released high heat while engraving, which causes the material to vaporize. Laser beam with high peak power and short pulse can create clear and permanent marks. It is applied to a wide range of materials, including metals, plastics, stone, etc.

Laser Etching:

Laser etching is a way to remove the surface coating from the base material. Given the high temperature released by the laser etching machine, the target object will be heated over its point of vaporization. Laser etching will leave a clear and permanent mark on an object with no damage left on its surface. Laser etching releases a laser beam to mark an object, and this technique doesn’t involve inks, or tools bits, which are friendly to the environment. This type of laser solution is gaining popularity among all walks of industries.

Laser Annealling:

Laser annealing heats metals slowly using a laser beam. With the metal heated, oxygen spreads below the surface and the metal begins to oxidize internally. When the metal cooled down, you can observe a color change of its surface. Laser annealing does not subtract anything from a metal surface. As a matter of fact, this technique does not change the metal’s surface roughness.Laser annealing technique is different from other laser solutions and its basic principle is thin-film interference.

By means of laser annealing, it is easy to change the surface color of some special metals, such as titanium and stainless steel, etc. In addition, laser annealing is ideal for materials that change color under increasing temperatures. Stainless steel surgical instruments and some titanium medical tools adopt this laser solution, which leaves a remark that can withstand sterilization and high temperatures.

Laser Color Change:

Generally, this technology is usually used for the precision processing of plastics. The heat released will destroy the carbon on the surface of the object, so the color of the plastic surface will change darker or lighter. The final color change will depend on the composition of the target material.

Laser Foaming:

Laser foaming technology is a process in which a laser beam is irradiated on a polymer material to melt and form foam-like bubbles fixed in the material structure.

In this case, the area of the material irradiated by the laser beam changes drastically, so the laser mark produced during the foaming process becomes clear and visible. This method is very suitable for industries that require high product marking. Laser foaming is most commonly used in packaging material production and the automotive industry.

Laser marking machine is also known as the laser code machine, laser marker, and laser symbol machine. And now, let’s together have a closer look at the differences between the several laser markers.

At first, it comes CO2 laser marking machine. Currently, CO2 laser marking machine is usually equipped with the CO2 RF laser tube, whose service life can be up to 50,000 hours. Generally, the marking speed of CO2 laser marker can reach 7,000 mm/s. CO2 laser marker is greatly suitable for marking on most non-metallic materials, i.e. paper packaging, plastic products, leather cloth, glass, and ceramics.

Secondly, it comes with a UV laser marking machine. UV-laser marking is especially appropriate for sensitive materials like silicone because surface structures are only slightly affected. At the same time, its short wavelengths enable excellent marking results. Even for micro text(text height under 0.1 mm), a UV-laser can attain a line width of under 10 µm. On the glass, a UV-laser can also provide filigree and brilliant marks of high quality. Drinking glasses or crystal watches keep their smooth surfaces, as a UV-laser produces micro-cracks of much smaller dimensions as compared to for example a CO2-laser.

Thirdly, it comes with a green laser marking machine. Green laser marking is designed to mark highly reflective materials or highly sensitive substrates like silicon wafers with ease and precision. They operate in the visible light spectrum at 532 nm (green color light). It’s perfect for softer plastics, PCB Boards, IC Chips, and for scribing or marking of Solar Cells of various material compositions.

Last but not least, it comes with fiber laser marking machines. They are most suitable for high-contrast markings, such as the metal annealing, etching, and engraving. The extremely small focal diameter enables them to be the ideal choice for the lasting marking of serial numbers, barcodes, and data matrix on metals. Fiber lasers find wide applications on the product traceability ( direct part marking ) and identification applications.

Fiber laser includes a pulsed laser and continuous-wave laser.

For the laser marking process,pulsed laser is the one. It releases the beam at a set rate. They’re ideal for laser marking applications because they boast a higher making speed.

As to the continuous-wave laser, it continuously emits the laser beam. They are more adapted to other laser applications, like laser cutting, welding, and drilling.

The laser is becoming a new method for most marking applications. Although it requires a higher initial investment than its alternatives, it provides a better return on investment. The satisfactory investment return is inseparable from the following benefits:

1. In most cases, it’s the fastest marking solution. Looking at aluminum marking performances, it’s possible to create a high-contrast data matrix code in just 1.40 seconds.
2. Laser marking is a traceability solution like no other. It offers near-perfect readability rates, thanks to the high reliability of laser systems and to the high contrast of marked identifiers. It can also create marks that are truly permanent, capable of withstanding almost any surface treatment such as e-coating, heat-treating.
3. It can be used to create permanent marks on materials whose surface cannot be directly marked (like stainless steel) by creating a mark under the surface.
4. Due to the high precision of laser marking, even very delicate graphics, 1-point fonts, and very small geometries will become clearly discern. Meanwhile, marking with the laser ensures constant high-quality results.
5. Laser marking is permanent and at the same time resistant to abrasion, heat, and acids. Depending on the laser parameter settings, certain materials can also be marked without causing damages to the surface.

Samples of laser engraver for metal:

The first laser marking machine came into life in the year 1965 when the laser marking machine only limits to the cutting. With the rapid hi-tech growth, more and more new functions have been developed.

At present, laser marking finds broad applications in industries, one of which is product labeling. To label products is often to achieve traceability; control quality; identify parts. Product labeling mainly comes in the following forms: data matrix codes, QR codes, and alphanumeric serial numbers. Generally speaking, the laser marking products will be labeled before the beginning of production, facilitating barcode readers to scan identifiers at the following manufacturing steps.

To some extent, this makes real the laser marking product traceability, from the beginning to the end of the manufacturing process. Plus, the labeling contains important information particular to each part or component. That means, it is convenient to timely conduct adjustment once the occurrence of deviation from what was expected.

The technology laser marking also finds wide applications in the automotive sector, metal processing, and manufacturing industries. Being widely applied, the technology laser marking brings many useful fruits to our daily life and production, such as laser marking steel, laser marking aluminum, laser marking metal, and laser marking plastic.
