Everything You Need to Know About Laser Marking Metal

September 8, 2022

Laser marking is a process that uses a laser to engrave an object with a permanent mark. This can be done for identification purposes, such as serial numbers or company logos, or simply for decoration.

Metal is one of the most common materials that is marked with a laser. This is because the laser can create a very deep and permanent mark on the metal surface. In addition, laser marking does not damage the metal like other methods, such as stamping or etching. You can also visit lasitlaser.de for gaining the best ever Laser marketing metal.

Types of Lasers

There are many different types of lasers that can be used for laser marking, but the most common types are CO2, Fiber, and MOPA lasers. This type of laser produces a beam of infrared light that is absorbed by the metal and causes it to heat up. As the metal heats up, it melts and the laser beam creates a mark on the surface.

CO2 Lasers:

CO2 lasers are typically used for industrial applications because they are very powerful and can create very deep marks. However, they are also quite expensive. For this reason, many companies that offer laser marking services use cheaper lasers, such as fiber lasers.

Fiber Lasers:

Fiber lasers use a different type of light, called fiber optic cable, to create their beams. These beams are much weaker than CO2 lasers, but they are still strong enough to melt metal. Fiber lasers are much cheaper than CO2 lasers and can be used for smaller projects.

MOPA Lasers:

MOPA lasers are a newer type of laser that is becoming increasingly popular for laser marking. And MOPA stands for “master oscillator, power amplifier.” These lasers use a fiber optic cable to create a powerful beam that can be used to mark metals and other materials.

MOPA lasers are more expensive than CO2 lasers and fiber lasers, but they offer many advantages. For example, MOPA lasers can be used to create very fine details and can even be used to engrave on a glass. In addition, MOPA lasers are much easier to control than other types of lasers, which makes them ideal for use in industrial applications.

Advantages for Laser Marking both Plastics and Metals

Laser marking has become increasingly popular in recent years as a means of permanently marking plastics and metals. There are several advantages to laser marking over traditional methods such as pad printing, hot stamping, and engraving.

Laser marking is permanent and cannot be removed or altered without damaging the material.
Laser marking is highly precise and can create very intricate designs or logos.
Laser-marked materials have a high-quality finish that is resistant to wear and tear.
Laser-marked plastics and metals are less likely to experience fading or other forms of degradation over time.
laser marking can be performed quickly and easily on a variety of materials, including both plastics and metals.
It is a cost-effective way to create permanent markings on large quantities of materials.
Laser Stamping can be used to create barcodes, QR codes, and other types of machine-readable data that can be used for tracking or identification purposes.
Laser-marked plastics and metals can be recycled or repurposed without losing the laser markings.
Laser marking is safe and does not produce any harmful emissions or fumes.
Many materials can be safely laser marked without affecting their structural integrity or performance properties.

Final Words

Laser marking is a permanent, precise, and cost-effective way to mark plastics and metals. Laser-marked materials are resistant to wear and tear, fading, and other forms of degradation. In addition, laser hallmark can be used to create barcodes, QR codes, and other machine-readable data.
