Laser Marking Automotive Parts

Functional marking of a turn signal

Materials suitable for laser marking

In the automotive industry, complete clarity and traceability of safety-related components is required. Optimal readability of Data Matrix codes and other alphanumeric labels is a prerequisite for this application. Laser machines are the ideal tool for reliably and quickly apply ID codes and other contents to most common materials used in the automotive industry. Whether you are laser marking plastics or marking metals with an industrial laser Trotec have a machine to suit your needs.

Materials suitable for laser marking

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


Automotive industry: Application examples

There are many laser marking applications within the automotive industry. From functional engravings such as Data Matrix codes and other dynamic content for quality assurance and traceability, laser marking can reproduce these with ease 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 equipment can also be used for designing logos and other data which can then be marked onto the components.

Why should I buy a laser for component marking?

Laser marking machines are capable of permanently labelling plastics, metals and other common materials with a high-contrast finish. The SpeedMark laser software for industrial lasers enables a fully automated labelling process with dynamic data that can be retrieved from ERP systems in the form of text or a wide range of different codes for direct component marking.

Function and advantages of laser technology

Flexible, dynamic data can be easily laser marked

  • Different engravings can be created from dynamic content without retooling or tool changes

Advantages of a Trotec laser

  • Intelligent and intuitive SpeedMark laser software 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

Component marking takes seconds with an industrial laser, creating fast production cycles

  • The labelling process is quick and easy thanks to industrial galvo technology

Advantages of a Trotec laser

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

Cost-efficient production

  • Direct component marking with an industrial laser does not require additional consumables such as inks, chemicals, pastes or sprays.
  • Eliminates 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 machines 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

  • A laser marking is permanent and is abrasion, heat and acid resistant
  • Permanent markings are 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 laser marking results - fine tools

  • The smallest shapes can be laser marked with extremely high accuracy
  • Marking processes can be combined to clean the material post-processing or to provide a higher contrast such as Data Matrix codes

Advantages of a Trotec laser

  • High-quality optics and optimal beam quality 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 small 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
  • Save time and achieve 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
