Materials suitable for laser marking

Nowadays, part tracking and traceability are elementary building blocks for success in the automotive and automotive supplier industry. On the one hand, systems are becoming technologically more complex, and on the other, development times are becoming shorter and shorter. In addition, quality requirements are constantly rising. Automotive manufacturers and suppliers apply various alphanumeric character sequences (e.g. serial or component numbers) and complex codes (mostly data matrix codes) to their products for this purpose, with which these can be monitored and traced at any time. Trotec Laser systems are an ideal tool to be able to reliably and quickly apply these codes and other contents to almost all materials that are used in the automotive industry while achieving a high-quality finish.

Materials suitable for laser marking

  • Steel
  • Steel alloys
  • Aluminum
  • Aluminum alloys
  • Coated metals
  • Plastics, such as polyamides, PP, ABS, etc.
  • Composites
  • Natural fibers


Application examples in the automotive industry

Typical application areas for laser markings in the automotive industry are functional engravings of data matrix codes and other dynamic content for quality assurance and traceability on all automotive parts made of plastics and metals.
In addition to the laser marking of parts and components, which are carried out for quality assurance or traceability purposes, laser marking in the automotive sector is also performed for design purposes.

  • Tachometer
  • Power window adjustment buttons in day & night design
  • Functional labels on components
  • Engine
  • Valve
  • Cylinder
  • Indicator
  • Seatbelt tensioner

Why should I buy a laser for component marking?

Laser marking systems are capable of permanently labeling most materials that are used in the automotive industry, with a high-contrast finish. This can be implemented through a stand-alone laser workstation or fully integrated into the production line. The SpeedMark laser software also enables a fully automated labeling process with variable data that can be retrieved from ERP systems in the form of text or a wide range of different codes for direct marking.

Function and advantages of laser technology

Flexible, variable data can be marked

  • A wide range of different engravings can be created from dynamic content without retooling or tool changes

Advantages of a Trotec laser

  • Intelligent and intuitive SpeedMark marking software that can process dynamic data from existing ERP systems

Integration into production lines

  • Hardware and software-sided integration into existing production lines is possible

Advantages of a Trotec laser

  • Years of experience of integrating OEM galvo laser systems into production lines
  • Software that meets all requirements for interfaces with other systems

Marking takes seconds and creates fast cycle times

  • High speed labeling thanks to galvo technology

Advantages of a Trotec laser

  • Maintenance-free galvo fiber lasers for fastest marking with minimal servicing

Cost-efficient production

  • Direct marking does not increase costs for consumables, such as inks, chemicals, pastes or sprays.
  • Eliminated need for disposing pricey materials.
  • No pre- or post-treatments are required
  • Tool wear is eliminated

Advantages of a Trotec laser

  • The SpeedMarker with a maintenance-free fiber laser can be integrated as a laser workstation or into a production line
  • The robust mechanics of Trotec laser systems have been designed for many years of intensive use with minimal servicing

Marking takes seconds and allows greater output

  • Marks at high speeds with variable contents (e.g. serial numbers, codes)
  • A wide range of different markings can be created without retooling or tool changes

Advantages of a Trotec laser

  • Intelligent and intuitive marking software for ease of use
  • Fast and highly accurate positioning of components through camera system: SpeedMark Vision - Smart Adjust
  • Integration of contents from ERP files is possible

Permanent markings

  • Laser marking is permanent and is abrasion, heat and acid resistant
  • Especially important for traceability and quality assurance

Advantages of a Trotec laser

  • Product portfolio with matching fiber laser systems for all requirements
  • OEM galvo fiber laser for integration into production lines
  • Custom-built systems according to customer requirements

Perfect marking results - fine tools

  • Smallest shapes can be marked with extremely high accuracy
  • Marking processes can be combined to clean the material after processing or to provide a higher contrast (e.g. Data Matrix codes)

Advantages of a Trotec laser

  • Ideal optics and optimal beam performance thanks to high-quality components
  • Camera-based component positioning for high precision and ease of use

Incredible design opportunities

  • Virtually any design can be produced with the laser: Logos, designs, bar codes, etc.
  • 1-point fonts and smallest shapes are still clearly legible
  • Even photos can be created in the shortest possible time

Advantages of a Trotec laser

  • DirectMark or JobControl software for laser markings directly from the graphics program make everything as easy as printing

Non-contact and reliable material processing capabilities

  • There is no need to firmly clamp down or fixate materials
  • Time savings and consistently high quality results

Advantages of a Trotec laser

  • Broad product portfolio with the right laser system for every requirement
  • Highly accurate laser marking even on your "first attempt" thanks to camera-assisted positioning
