industrial marking and marking of promotional products

The laser has been a prominent tool for many years now, especially when it comes to laser engraving and laser marking metals. Soft metals, like aluminium can easily be marked. But it’s also possible for hard metals like steel and solid alloys to be laser marked accurately and quickly. It is even possible to implement corrosion-resistant markings onto steel alloys without damaging the surface structure of your metal. Products made of metal are typically marked with a laser engraving machine in many different industries, including industrial industries as well as gifts and personalisation industries.

Suitable Metals for Laser Marking & Engraving:

  • Stainless Steel
  • Aluminium
  • Anodised Aluminium
  • Hardened Metals
  • Alloyed Steels
  • High-Speed Steels
  • Titanium
  • Titanium Alloys
  • Carbides
  • Brass
  • Copper
  • Precious Metals (silver, gold)

Industrial Laser Marking

Examples of Applications

Laser Marking Metal in the Industrial Sector

Applications for Laser Marking Metal

Metal laser marking is typically used when making products that need traceability features and/or codes. These kinds of applications are popular in the electronics and electrical industry, for mechanical engineering, tool manufacturing, sheet metal processing, medical technology, promotional materials, jewellery crafting, the automotive industry and much more.

Colour Marking on Stainless Steel

A particularly special kind of marking involves colour marking on stainless steel. Due to the vast technical possibilities of the MOPA laser, reproducible and consistent colours can be narked quickly and easy with the right machine. For manufacturers of stainless-steel products, it is now possible to mark special coloured designs. This includes things like company logos and directional instructions on stainless steel fixtures.

“What is the point of buying a laser for industrial metal marking?”

Contactless, permanent metal marking:

Marking metals using a laser machine is a very precise and clean way to process metals. Serial numbers, data matrix codes and logos can easily be added to products and components quickly and perfectly. The marking or engraving is done by the powerful laser beam, so there is never any contact with the material and will never require any pre- or post-processing. Annealing marking ensures a permanent, acid, chemical and corrosion free mark.

Laser Marking Metal & the Possibilities!

There are many different methods for marking and engraving metal. Depending on the material you are using and the quality requirements, aluminium, stainless steel and many other types of metal can be engraved, marked or polished with the innovative laser beam. Each method has specific advantages and disadvantages. Read on to lean more…

"How does metal engraving work?"

Engraving and (depending on the amount of material removed) removal of metal leaves a tangible, noticeable marking. The material physically evaporates, and the colour of your workpiece will change and create a mark. Due to the intense energy of the laser engraver, materials like stainless steel and titanium can be directly vaporised. The brown colour that is left behind on the metal can be tidied up using other metal marking processes (see polishing).

"How does metal polishing work?"

Polishing leaves a clean, white mark on stainless steel, as well as many other kinds of metal. Polishing is a ‘lighter’ type of engraving process. The energy of the laser machine is reduced so that hardly any material can evaporate. This results in less material removal and a white mark being left behind.

"How does laser marking work?"

Laser marking / annealing marking is an imperceptible process that doesn’t affect the surface of your material. No material is ever removed during this procedure. By heating the metal in a controlled way, however, you produce a colour change. For example, the colour of a piece of stainless steel changes at a temperature of 200-300°C. Different colours can also be achieved when you use differing temperatures. Even though the standard ‘goal’ when marking metal is 100% black, sometimes it is desirable to mark something with different colours. However, perfect black markings are only possible on stainless steel and titanium – not on any other metal. But, you can get very close.

Engrave & Mark Metals with CO2 or Fiber Lasers?

The best tool for productive and quality metal marking is easily the fiber laser. There is no pre- or post-processing involved and the marking result is always uniform and precise, even for fine details.

Uncoated metals can only be marked with a CO2 laser machine with the use of laser marking solutions, like pastes and sprays. This must be applied to the workpiece prior to the laser process. It needs to dry completely so it can thus be burned into the material. Then, once the laser process is over, the leftover paste needs to be carefully washed off.

Marking sensitive surfaces, like expensive workpieces or unique pieces from customers, can become somewhat risky when using engraving consumables likes engraving pastes and sprays. Marking solutions are also technically classified as hazardous materials. Henceforth, the corresponding safety regulations must always be adhered to when using these products.
