Quick select


It is essential for components to be fully traceable in the automotive industry, and not just for safety and technical reasons. Unique, forgery-proof and easy to read – these factors are of maximum relevance in the automotive industry. Data matrix codes and alphanumeric inscriptions are usually used for this. The laser markers from JustLaser can be used to immortalise these important codes on almost any material: regardless of whether the components are made from metal or plastic, the process ensures durable, perfectly legible and quick labelling.


Laser marking in the automotive industry offers a number of benefits: protection against forgery, durability, maximum precision and speed as well as a high contrast – they all make laser technology the ideal method for labelling components.

As laser inscriptions are also resistant to thermal stress and contact with acids, petrol, oil and heat, maximum traceability is permanently guaranteed for individual components in terms of quality. Thanks to simple operation (software packages) and high throughput rates, laser marking is also beneficial from an economic perspective.

Our Laser Machines for Marking


A number of different materials in vehicles are processed – from steel, plastic and light metals to natural fibres. It’s all the more valuable that the laser markers from JustLaser provide high-quality results on almost any material. Laser marking in the automotive industry is possible on almost any surface:

  • Natural fibres
  • Aluminium and alloys
  • Coated metals
  • Glass
  • Composites
  • Steel and alloys
  • Various plastics

Which car parts are marked using lasers?

Data matrix codes, alphanumeric and functional inscriptions are standard in the automotive industry. For optimal traceability and maximum durability, laser marking is the established process for marking individual components in the automotive industry. Laser engraving can be used to produce logos and design elements on a range of components. Regardless of whether they’re plastic, aluminium or metal elements – with the laser markers from JustLaser, you can rely on high precision and maximum quality! The following components are frequently marked using a laser marker:

  • Actuators
  • Tachometer
  • Rev counter
  • Valves
  • Warning and information signs
  • Connectors
  • Window controls (day/night design)
  • Components (functional inscription)
  • Engine parts
  • Lacquer and plastic inscriptions
  • Indicators
  • Seatbelt tensioners
  • Type plates

Which vehicle components are marked using lasers?

  • Luminous day and night lettering: laser marking is the established process for applying luminous day and night designs to window controls. In this process, the JustLaser Laser Marker carefully removes the respective layers of lacquer from the multi-layer lacquered plastic elements. The translucent plastic material becomes visible as a result. Special 2-component injection moulding technology used to be used for this. Now, laser marking is the cheapest and most flexible variant for day and night lettering on vehicle components.
  • Marking tyres: tyre manufacturers use laser markers to print serial numbers, important information and matrix codes on their care tyres. The durability – even with high levels of abrasion – and cost efficiency mean laser technology is massively impressive to tyre manufacturers.
  • Graining and surface texture: while graining is etched on the interior of large elements, it is significantly easier and more economical to engrave it with a laser on small parts. Laser markers can also be used to make corrections on defective surface structures. Predefined structures (3D data models) of workpiece surfaces can also be produced. It is possible to produce geometric shapes and irregular elements (e.g. leather grains).
  • Film marking/information and warning signs: direct laser marks aren’t always sensible. In such cases, special laser-marked multi-layer films are applied to vehicle components. After the inscription process, the laser marker is used to cut out predefined contours without damaging the backing film. The films are extremely resistant to thermal and chemical influences and, thanks to heavy-duty adhesives, permanently adhere to a variety of materials (steel, aluminium, plastic, lacquer, etc.).
  • Type plates: JustLaser laser markers can be equipped with a variety of type plate magazines and make it possible to mark a variety of different sizes simultaneously. The laser lens ensures precise engraving and marking fully automatic.


Laser machines are used especially frequently in the supply industry nowadays. Laser cutting technology is considered extremely beneficial for working with plastics and textiles in vehicles – for two-dimensional applications, for example. You can benefit from the clear cutting of a laser cutter when producing a number of components for the interior and exterior of cars: using a laser to cut spacer fabrics without crushing is just as popular as using a laser to cut fibreglass textiles for heat-protection textiles. It also possible to produce reliefs or large-format structures over entire processing surfaces.

The focussed light of the laser cutter guarantees standardised, high production quality. The clean cuts do not cause textiles to become frayed, for example, meaning it is no longer necessary to carry out subsequent work on the material. As the material doesn’t need to be fixed in place, no unsightly deformations occur as a result of laser cutting. Contactless, precise, simple – that’s what characterises laser marking in the automotive industry.


In the supplier industry, the process of laser marking has prevailed over alternative processing options in the automotive industry. The range of functional parts and components cut with a laser is particularly extensive in the vehicles industry:

  • Fittings
  • Cladding
  • Fibreglass composites (heat-absorbing)
  • Displays
  • Membrane keyboards
  • Protective coats
  • Polyester fabric (e.g. wind deflectors, keyboard foil)
  • Insulating mats
  • Covers
  • Spacer fabrics for car seats
  • CFRP composites
  • Textiles (e.g. seat cushions)
  • Vehicle emblems (technical adhesive films)
  • Many more


With the JustLaser Laser Marker, you can also benefit from low investment costs and set-up costs in comparison to other devices and purchase a high-quality product that will win you over through its high throughput speed and precision! The laser parameters can be flexibly adjusted to the material in question to achieve optimal results. Even the finest lines and delicate patterns can be produced perfectly.

Thanks to consistently-high cutting quality and maximum flexibility in the selection of contours, the laser machines from JustLaser offer many benefits in more than just the vehicles industry.
