We&#;ll start by discussing the applications of laser marking machines. Then, we&#;ll get into the essential qualities that all reliable laser markers should have. We&#;ll cover everything from maintenance considerations to achieving your desired results. So read on to learn six factors to consider when choosing a laser marking machine.

What Is a Laser Marking Machine?

Laser marking machines are devices that do exactly what their name suggests&#;add marks to surfaces. A few different types of laser marking machines exist, as there are several ways to mark surfaces.

• UV laser marking: When you think about laser marking machines, this is the device you picture. A laser cuts deep marks into your material through the process of disintegration.
• Laser etching: Laser etching is a quicker process that can cut high-contrast marks quickly. The laser melts a portion of the surface material and creates easily readable high and low bumps.
• Laser annealing: Annealing is a chemical process that occurs under the surface of your material. The laser doesn&#;t melt your material. Instead, it causes a chemical change under the surface. This is a non-destructive process for precise applications.
• Laser ablation: Laser ablation is a weaker process that removes paint from a material rather than the material itself.

Laser marking machines of all types have applications in the military, automotive, medical, and pharmaceutical fields, to name a few.

Marking Speed

The first factor to look for when choosing a laser marking machine is the marking speed. While laser marking is one of the fastest available marking processes, there&#;s still a high variance between high- and low-end models.

In addition to model quality, the material you want to mark and the size of your markings will determine your marking speed. Depending on the type of marking you&#;re after, you may enjoy a faster or slower process. For example, laser annealing takes much longer than etching. However, it produces an indelible mark without harming the surface of your material.

UV Laser Marking Accuracy

Not all industries have the same requirements for accuracy. Some fields may need to carve in identification numbers quickly. Others may require higher precision, such as the medical or pharmaceutical fields.

Industrial laser marking machines have a few factors that can influence accuracy. One is the size of the beam spot on your material. The smaller that spot is, the more precise the laser can get. Another is the quality of the optical system and thermal control. Even slight variations could produce consistently disappointing results.

The Materials You&#;re Using

Work with a laser manufacturer to determine what type of laser you need based on the material you&#;re planning to mark. Many industries plan to mark metal. In that case, blue lasers are often the best choice.

Optic Properties of the Material

Different materials have a wide range of optic properties. These differences can cause the same laser to interact with various materials in unusual ways. Most of the time, people require their lasers to etch or mark opaque materials. When someone needs to mark a translucent or transparent material, they must do a little extra work to make their laser perform properly.

Because translucent materials allow light to pass through them, scattering the light, laser marking can get a bit tricky. One thing you can do is to add a dark layer beneath your translucent material and recalibrate the working distance of the laser.

Additionally, the color of your material may come into play when marking. For example, black acrylic is easier to mark than green acrylic. That&#;s because black materials absorb all light while green materials absorb all but green wavelengths. This slight difference can change the UV laser marking time of your project.

The True Cost of Ownership

Some companies want to convince you that a laser marking machine is a one-time purchase, but that just isn&#;t true. No one plans to buy a laser marking machine and throw it away after it performs at peak efficiency for a year. When you purchase a machine, you want to know how long it will last and what sort of maintenance you need to plan for during its lifespan.

Good machines should function for around a decade and should not require excessive maintenance. Be wary of companies that advertise their machines as being &#;easy to fix&#; because you can expect that you&#;ll need to fix them often.

The Mix of Functionality, Reliability, and Affordability

The best laser marking systems balance their function, reliability, and affordability. When you start to sacrifice any of the three, you set yourself up for a situation you don&#;t want to be in. It&#;s better to research a ton and buy once rather than take a shot in the dark and regret it. Our laser marking systems strike a better balance than any others.

Choosing a Reputable Seller

You should make every large investment with confidence. While you may hope that all laser marking machine providers understand their products, you can&#;t be sure until you see for yourself. When you get on a call with a salesperson, you must make sure they can explain to you how the machine functions and ensure they have a good sense of the machine&#;s applications.

If you notice that a salesperson doesn&#;t have a grasp on the products they&#;re selling, how can you expect them to recommend the best system for you?

Now that you know these six factors to consider when choosing a laser marking machine, you should look over all your options before you make a decision.

How to Choose the Right Laser Marking Technology

You should examine and consider three main factors before choosing the right laser marking technology.

· Number #1: Material

The first thing that should come to mind is the type of material you want to mark. When looking into laser marking, there are two categories of materials: organic and non-organic. Organic materials are carbon-based materials from living organisms such as wood, glass, paper, and plastic are examples of organic materials. Non-organic materials include metals, cast aluminum, and steel.

The material you want to mark using a laser should be compatible with the marking technology. For example, UV and green laser marking are suitable for thermolabile substances. Fiber laser machines are suitable for non-organic materials, while CO2 laser technology is used for organic materials.

· Number #2: Type of Mark

There are different ways laser marking can be done, each with uniqueness in terms of what the marks look like. Due to the type of marks obtained, each one has different applications. For example, barcode marking will require you to have a dark or frosty mark so that people will not have a problem reading the codes

Each technology used for laser marking has varied capabilities that result in different types of marks. Choosing the most appropriate type of mark is a crucial step. Below are the common types of laser marks.

&#; Engraving

Laser engraving involves using a laser beam to physically peel off a material&#;s outer surface, leaving a visible engraved mark. It is the most common method for customizing and personalizing different products. You can have different laser marking technology depending on the material, although fiber laser markers are the most common. Laser engravable materials include wood and plywood, leathers, and glass. Bricks and stones.

&#; Etching

Laser etching involves using a laser beam to melt and raise a material&#;s outer surface, leaving a visible engraved mark. It is like laser engraving and is also applicable for customizing and personalizing different products. However, unlike engraving, it has wider material supports and lower cut depth, reducing the markings&#; permanency. Fiber laser markers are the only laser etching machines due to the high energy required

&#; Layer removal

Laser layer removal involves vaporizing the covering layer of a product using a laser beam. This makes the main material visible again and results in a marking effect. This method is suitable for indirectly marking label-coated materials such as laser marking films and painted base materials. The laser technology depends on the material, with CO2 laser engraving machines and fiber laser marking technology being the most common.

&#; Carbon Migration

They are also referred to as &#;black annealing.&#; It involves heating the material to bring the carbon to its surface due to its release from carbon-containing compounds. Therefore, the surface becomes dark, and black laser marking is sometimes left behind. Metals and sometimes metal alloys can be used.

&#; Bonding

Laser bonding is an additive technique that involves binding another material to the surface of the material being marked. Unlike other methods, it does not remove part of the materials you want to mark. It is common to mark glass, stoneware, and metals.
