Laser Marking in Mechanical Engineering

Machine Construction

aluminum part laser marked

In mechanical engineering, parts and components of resistant materials are often used. Especially when it comes to guaranteeing traceability, laser marking and laser labeling is perfect. It is permanent and resistant, even to mechanical stress or weather influence. Laser marking can be used on all forms on almost any material and is a suitable tool for a wide range of components in machine construction. The parts marked with the laser can be implemented on almost any material and in all forms. Therefore, it is a universal tool that is able to mark a variety of parts with a laser.

Suitable materials for laser marking

  • Parts and components of resistant materials
  • metals
  • hardened metals
  • stainless steel
  • coated metals
  • aluminum
  • anodized aluminum
  • plastics


Application examples laser marking metal and other parts marking in mechanical engineering

The parts marking in machine construction takes place due to 3 reasons:

  • Information regarding the technical function of the workpiece (product information)
  • Indications regarding the product or manufacturer for the traceability (variable data as e.g. batch number, production date, etc.)
  • Permanent laser marking (e.g. logo) as counterfeit protection

Laser Marking Metal | MetroNorth

Meet Metro North Machine & Design Inc, a machine shop specializing in metal part manufacturing. They use the Speedy 300 flexx laser machine to laser mark industrial parts. They use both Fiber and CO2 laser sources in the Speedy 300 flexx for their industrial applications. The CO2 laser is used for marking anodized aluminum and plastics while the Fiber laser is used for annealing stainless steel.

What is the point of buying a laser for laser marking in mechanical engineering?

Efficient and cost-efficient laser marking
Thanks to the intelligent software solutions from Trotec, you can also easily generate serial numbers, dates, part numbers or date codes and use them to inexpensively mark parts or workpieces. This guarantees independence from external marking service providers and high quality for your products. You can also easily produce your own identification plates or other markings and save time and money! Trotec's software packages guarantee smooth process integration.

Function and advantages of laser technology

Cost-efficient production

  • Direct marking means no costs for consumables such as chemicals, pastes or sprays
  • The handling and the often expensive disposal of these materials is also dispensed with
  • Pre-treatment and post-treatment are not necessary
  • No tool wear

Advantages of a Trotec laser

  • SpeedMarker with a maintenance-free fiber laser as a laser work station or it can also be integrated into a production line
  • The robust mechanics of the Trotec laser systems is designed for years of intensive use with minimal servicing.

Flexible, dynamic data can be laser marked

  • Different markings with dynamic content possible without refitting or changing tools

Advantages of a Trotec laser

  • Intelligent and intuitive marking software SpeedMark, which can easily process data from existing ERP systems and all dynamic contents in codes

Markings in seconds for more throughput

  • Very fast marking possible, even of variable contents (e.g. serial numbers, codes)
  • Different markings possible without refitting or tool change

Advantages of a Trotec laser

  • Intelligent and intuitive marking software for easy operation
  • Fast and precise positioning of components using a camera system: SpeedMark Vision – Smart Adjust
  • Integration of contents from ERP data files possible

Integration into production lines

  • Hardware and software integration into existing production lines possible

Advantages of a Trotec laser

  • Longstanding experience of system integration of Galvo OEM lasers in production lines
  • Software which fulfills all requirements of the interfaces with other systems

Permanent marking

  • In contrast to other technologies, laser marking is permanent and abrasion-resistant, additionally heat- and acid-resistant
  • Particularly important for traceability and quality assurance

Advantages of a Trotec laser

  • Product portfolio with matching fiber laser systems for all requirements
  • Flatbed systems with a working surface up to 28.58" x 17"

  • OEM Galvo fiber laser for integration into production lines
  • Special systems according to customer requirements

Perfect marking results - fine tool

  • Precise and smallest geometries can be laser marked in a highly accurate manner
  • Marking processes can be combined in order to clean the material after processing or to create a higher contrast (e.g. with data matrix codes)

Advantages of a Trotec laser

  • High-quality optics and best beam quality thanks to high-quality components
  • Camera-based component positioning for maximum precision and ease of use

Non-contact and process-safe material processing

  • The material does not have to be tightly clamped or fixed
  • Time saving and consistently good results

Advantages of a Trotec laser

  • Broad product portfolio with suitable laser system for every requirement
  • Highest accuracy of the laser marking already at the "first shot" by means of camera-supported positioning
