With its speed, flexibility and precision, the N-Lase fiber laser machines are the perfect solution for marking metals, coated metals and plastics.

Over the past decade, the laser marking machine has become an essential tool for numerous manufacturing facilities worldwide. In particular, laser marking is heavily used in industries such as medical, aerospace, automotive and electronics, where traceability is an integral part of the manufacturing process.

How does a fiber laser marking machine work

Annealing

The annealing process works by gently heating a metal to a specific temperature to create a smooth mark – either black or coloured. The key advantage of the annealing process is the crisp, smooth and permanent mark that can be created with the laser on a large variety of materials.

Foaming

Foaming is used to mark plastic applications. The process is achieved by melting a localised area of the plastic’s surface using the heat generated from the laser beam. The “foam” effect is created by the build-up of heat, which causes the surface of the plastic to bubble. Most commonly, the foaming laser technique is used to add serial numbers, part numbers, and other product information onto plastic objects.

Carbon migration

Carbon migration is used to create a smooth black mark on steel, stainless steel, carbide and titanium metal surfaces. The process works by generating heat to bond the surface of the metal with carbon molecules, which results in the carbon changing the top colour of the metal’s surface. The carbon migration process is a sterile technique that is heavily used in the medical industry to add traceability codes to medical parts and devices.

Discolouration

The discolouration process works by tweaking the laser parameters, such as the wavelength, width and pulse frequency, to generate the appropriate amount of heat to get the desired colour on the metal or plastic surface. This process is used for multiple applications, including giftware, decorative jewelry, product branding and more.

Direct part marking (DPM)

Direct part marking – or DPM for short – is used by automotive, medical, aerospace and electronic industries to track the lifecycle of parts and components during the manufacturing process and supply chain.

By adding a machine-readable code, such as a barcode, serial number, date code or part number, to every stage of manufacturing; companies can implement stringent traceability practices to meet regulatory requirements.

In particular, DPM tracking is essential for resolving liability or warranty issues, tracing parts for service or recalls.

Advantages of using the N-Lase fiber laser machines for marking applications

Flexibility with materials

The N-Lase laser markers can be used for steel, stainless steel, aluminium, titanium, cast iron, copper, gold, silver, abs plastic, polycarbonate, polyamide and more

 

Fast process

A simple barcode or part number can be marked in a blink of an eye. We work with each of our customers to find the ideal parameters that combine speed with high- quality marking results.

 

Can be automated

For large volume applications, the machines can be automated to deliver a fast-paced marking solution.

 

Crisp and sharp quality

The quality of the mark is second to none! Even the smallest and intricate designs can easily be marked with our machines.

 

Multiple file formats

The N-Lase Designer software, which comes with our machines, supports various file formats such as DXF, AI, PLT, Bitmap or JPEG.

 

Permanent marks

In contrast to most printing methods, the laser offers a permanent mark even under extreme industrial environments.

 

Non-contact

There is no physical contact with the surface of the object during the marking process. As a result, the marking machine is a perfect solution for germ-free, anti-rust traceability requirements.
