Materials suitable for laser marking

In the metal laser marking and the automotive industry, complete clarity and traceability of protective elements should be ensured. Optimum readability of data Matrix codes or alternative alphamerical labels is a requirement for this application. Laser marking systems are a perfect tool to be able to reliably and quickly apply these codes and alternative contents to most materials that are used in the automotive industry while achieving a high-quality end.

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 component marking and laser markings inside the automotive industry are for engravings of data matrix codes and various dynamic content for quality assurance and traceability on all automotive components manufactured from plastics and metals.
In addition to the laser marking of automotive elements and components, which are dispensed for quality assurance or traceability functions, laser marking inside the automotive sector is additionally performed for design functions.

  • Speedometer
  • 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 utilized in the automotive industry, with a high-contrast end. This can be implemented through a stand-alone laser workstation or fully integrated into the assembly line. The SpeedMark laser software system conjointly permits a fully automated labeling process with variable data that can be retrieved from ERP systems within the form of text or a large range of various codes for component marking and 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

Laser 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

Laser 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 

Advantages of a Trotec laser

  • Intelligent and intuitive marking software for ease of use
  • Fast and highly accurate positioning of component marking 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, such as the automotive industry 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 laser 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
