What is a Laser Marking Machine?

Laser Marking Machine introduction:

Laser marking machine can mark in a variety of different materials’ surface with a permanent mark. Marking effect is through the material surface to reveal the deep material evaporation, which engraved exquisite patterns, trademarks and text.

---The principle of laser marking machine:

1. “Thermal processing "has a high energy density of the laser beam (which is a concentrated energy flow), irradiated on the surface of the material being processed, the material surface absorbs laser energy, in the irradiation area to generate a thermal excitation process, so that the material surface (or coated Layer) temperature rise, resulting in metamorphosis, melting, ablation, evaporation and so on.

This way the laser marking machine can be divided into:

CO2 laser marking machine

fiber laser marking machine

2. “Cold processing" has a very high energy photon, can interrupt the material (especially organic materials) or the surrounding medium chemical bonds, to the material non-thermal process damage. This cold work has a special meaning in laser marking processing. Because it is not a thermal ablation, so the processed surface layer and the area does not produce heating or thermal deformation.

It including:

UV laser marking machine

Green laser marking machine

Infrared laser marking machine

----Marking materials difference:

I. YAG laser marking machine only can mark on metal materials, such as steel, brass, aluminum, etc.

II. Co2 laser marking machine main used to work on nonmetal materials, such as wood, leather, glass, paper etc.

III. Fiber laser marking machine can used on almost all the metal and nonmetal materials except wood and transparent materials(glass, acrylic).

IV. UV, green and Infrared laser main use in high-end extremely fine IC product marking, price is high.

NOTE: Due to YAG laser has so many consumable parts and difficult setting,so now YAG laser almost not selling in the market. Most work can be replaced by the fiber laser.

Co2 laser marking machine:

It can engrave on most non-metallic materials: paper, leather, wood, plastic, plexiglass, fabric, acrylic, bamboo, rubber, crystal, jade, ceramics, glass and artificial stone.

The co2 laser source can choose Chinese glass tube, and imported metal laser tube, the main brand is Synrad, coherent and Rofin.

The difference is the lifespan, the glass tube lifespan about 3000-5000 hours, the metal tube lifespan is about 20000-40000 hours.The metal tube can be air inflation for reuse.

The difference between Laser engraving machine, Laser etching machine and Laser marking machine

What is the difference between Laser engraving machine, Laser etching machine and Laser marking machine?

Laser engraving machine, Laser etching machine and Laser marking machine provide a permanent message on an in-process or finished component. We can engrave, etch or mark text, serial numbers, part numbers, company logos, bar codes, QR Codes, ID matrix codes or 2D codes on all plain, painted, anodized, or plated metal surfaces, whether they are flat sheets, curved surfaces, or cylinders.

With the development of the CNC laser technology, the processes of Laser engraving, Laser etching and Laser marking are increasing in popularity. All the three laser services provide a permanent marking solution, fulfilling regulations and adding distinction to your products and parts.

How to distinguish between Laser engraving machine, Laser etching machine and Laser marking machine?

Although these terms are often used interchangeably, there are differences between Laser engraving machine, Laser etching machine and Laser marking machine. Each type of laser machine has its own applications and attributes that make it ideal for different jobs.

Laser engraving machine

Laser engraving is a process where the laser beam physically removes the surface of the material to expose a cavity that reveals an image at eye level.

1. This creates a cavity in the surface that is noticeable to the eye and touch.
2. It’s a quick process, as the material is vaporized with each pulse.
3. To form deeper marks with the laser engraver, repeat with several passes.
4. The laser creates high heat during the engraving process, which essentially causes the material to vaporize.

Although laser engraving is a subsection of laser marking, it still differs in many ways:

1. This is the most common option for people who want something personalized or customized.
2. There are three types of laser engraving: etching, deep laser engraving and laser ablation (the difference between the three is what the surface is and how much you remove).
3. Not ideal for marking safety critical parts.
4. This is the fastest way to mark with a laser.
5. Maximum engraving depth is 0.020″ in metals but can go as deep as 0.125″ in materials such as graphite.
6. It’s great for parts expected to experience high wear.
7. You can engrave on almost any kind of metal, plastic, wood, leather and glass surface.
8. It’s typically used to engrave serial numbers and logos, among other things.

Another important comparison to make is how laser engraving compares to traditional engraving:

1. It provides you with more font options.
2. It can be done on a number of materials.
3. It is more legible than traditional engraving for small objects such as jewelry.
4. Laser engraving machines are faster than traditional methods.
5. There is a smaller chance of product damage or deformation.

Laser etching machine

Laser etching, which is a subset of laser engraving, occurs when the heat from the beam causes the surface of the material to melt.

1. Unlike with engraving, the depth in etching is typically no more than 0.001”.
2. The laser beam uses high heat to melt the surface of the material.
3. The melted material expands and causes a raised mark.

The differences between laser etching, engraving and marking include:

1. It removes 0.001″ or less of the material.
2. It can be done on bare, anodized or plated metal surfaces, as well as polymers and ceramics.
3. Since a laser etcher changes the surface finish of metals, it alters its reflectivity and enhances contrast.

Laser marking machine

Laser marking is what happens when the beam interacts with the surface of a material, slightly altering its properties or appearance.

Laser heats the material, causing oxidation under the surface and turning the material black.
It is achieved by moving a low-powered beam slowly across the material using a method called discoloration, which creates high-contrast marks without disrupting the material.
All of this is done while leaving the surface intact.

It applies low temperatures to metal to anneal the surface.

https://www.stylecnc.com/laser-marking-machine/
Laser marking machine differs from laser engraving machine and laser etching machine in a number of ways:

1. A laser marker is ideal for bar codes, UID codes, QR codes, logos and other identification needs.
2. There are four common types of laser marking: annealing, carbon migration, foaming and coloration.
3. It’s popular in the medical device industry for stainless steel and titanium parts, but can be performed on other materials as well.
4. It is also referred to as laser coloration or laser dark marking, as well as charring for plastic materials and annealing for metals.
5. It is less common and not all places offer these services.
