How to Choose the Right Laser Marking Technology?

Jan. 10, 2023

How to choose the right laser marking technology Before choosing the right laser marking technology, you should check and consider three main factors.

 

Point 1: Material

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

 

The materials you want to mark with the laser should be compatible with the marking technology. For example, UV and green laser marking is suitable for non-heat resistant materials. Fibre laser machines are suitable for non-organic materials, while CO2 laser technology is suitable for organic materials.

-Point 2: Types of marks

Laser marking can be carried out in a number of different ways, each of which is unique in terms of the appearance of the mark. Each has a different application due to the different types of marks obtained. For example, barcode marking will require you to have a dark or cool mark so that people do not have problems reading the code

 

Each of the technologies used for laser marking has different features, resulting in different types of marks. Choosing the most appropriate type of mark is a vital step. The following are common types of laser marks.

 

-Engraving

Laser engraving involves the use of a laser beam to physically peel away the outer surface of a material, leaving a visible engraved mark. This is the most common method for customising and personalising different products. Depending on the material, you can use different laser marking techniques, but the most common is the fibre laser marker. Materials that can be laser engraved include wood and plywood, leather and glass. Brick and stone.

-Etching

Laser etching involves the use of a laser beam to melt and raise the outer surface of a material, leaving a visible engraved mark. It is just like laser engraving and is also suitable for customising and personalising different products. However, unlike engraving, it has a wider material support and a lower depth of cut, which reduces the durability of the mark. Due to the high energy required, fibre laser markers are the only laser etchers.

 

-Layer removal

Laser layer removal involves the use of a laser beam to evaporate the covering layer of the product. This makes the primary material visible again and produces the marking effect. This method is suitable for indirect marking of label coating materials such as laser marked films and painted substrates. The laser technology depends on the material, the most common being CO2 laser engraving machines and fibre laser marking technology.

-Carbon migration

They are also known as "black annealing". As carbon is released from the carbon-containing compounds, it involves heating the material to bring the carbon to its surface. As a result, the surface is darkened, sometimes leaving a black laser mark. Metals and sometimes metal alloys can be used.

 

-Bonding

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

 

-Point 3: Safety considerations

The next thing to consider is the location of the laser marker. These include the setup, the type of location (whether restricted or not), the presence of other marking systems and the hazards that accompany the technology.

 

If your laser engraver is set up in an open shop, your supplier should assist you in installing a Class I safety system. Class I safety systems include laser safety cages, warning lights and curtains for safe entry and other safety features.

 

Another option is a laser workstation with Class I safety restrictions and a laser source. If you have a Class IV laser, you will need an isolated room that meets certain safety standards (e.g. goggles, area posting and key switches) to meet the safety requirements.
