Laser marking in the Automotive

Product traceability plays a central role in the automotive industry. Keeping the enormous supply chain under control is extremely importance to increase productivity and reduce costs. Traceability is the main requirement in the automotive industry, where the huge number of vehicle components come from different suppliers.

All automotive components carry an ID code, which can be a Barcode, a QRcode, or a DataMatrix. Through these we can trace the manufacturer, and the time and place of component production. This makes it easier to manage any component failure, thus reducing the risk of errors.

Laser marking

Laser marking is the primary traceability tool for automotive component manufacturers. All metal and plastic vehicle components require laser marking. For this reason, LASIT has developed more solutions for this sector than for any other over the years.

Laser marking is indelible and contrast is always high. The most widely used laser is the infrared light-fiber source, with power ranging from 20 to 100 Watts. Naturally, LASIT laser markers allow for reading and grading the marked DataMatrix code. All laser markers can be fitted with a vision system.

Advantages of laser marking for the automotive industry

Data dynamism

we can connect to the customer’s manufacturing management (MES-ERP) system. This allows us to manage dynamic data, production batches, and automated marking sequences, no matter how complex.


speed and automatic data management go hand in hand with mechanical automation. LASIT can integrate its systems into any production line and mechanically create a structure to ensure total efficiency in traceability management.

Quality and durability

no other technology offers the same precision as laser marking. And no other marking is as durable. This brings us neatly to the next point, which is a synthesis of what we have already explained.



laser marking is dynamic, automatic, and precise. LASIT is able to design process automation that speeds up manufacturing. Laser marking, code verification, component movement to the next stage of the chain – all processes operate at peak efficiency


our FlyCAD software allows for the generation of all codes, which comply with applicable standards. We specialize in customized software design. This software is designed to communicate with the company database or line supervisor, and for automatic recall operations based on reading of the marked code.

2D Codes: Laser marking

All Datamatrix codes marked with LASIT software use the ECC200 error correction system, which is the current industry standard. This system supports advanced control and error correction algorithms, allowing for the practical reconstruction of up to 30% of the entire encoded data set. This means that the symbol is still legible even when it is 30% damaged, which would be impossible using linear barcodes.

Marked codes: Difference between reading and verification

Readers are designed to read the various codes and can be used directly online due to their speed. The information provided allows us to check the accuracy of the encoded data and compliance with the specific formatting standard.

Code verifiers, on the other hand, ensure that data are correctly marked and meet a qualitative threshold with respect to a reference standard. A verifier takes longer to parse a code and generates more data than reading alone, which only spells out the encoded data.

Some types of readers can grade the quality of the Datamatrix code. As with verifiers, grading also takes into account the international reference standards, but the result can be obtained in real time and used on-line. Unlike verifiers, however, readers do not account for calibration and lighting positions. Nevertheless, they still provide an important indication of the marking quality.

The current verification standards for codes are as follows:

  • ISO 15415 for 2D barcodes printed on labels.
  • ISO/IEC TR 29158 (also known as AIM DPM) for 2D DPM barcodes.
Laser marking on die-cast components

Laser marking on die-cast components has been one of the biggest challenges for laser manufacturers. One of the main obstacles is ensuring legibility of the marked code after sandblasting and shot peening.

These are highly invasive processes on die-castings, and can compromise the quality of pre-finished laser markings. LASIT has carried out numerous tests to ensure the quality of codes after sandblasting. Through the study and implementation of deep engraving parameters we were able to achieve the desired result. LASIT laser marking is resistant to sandblasting on die-cast components.

Laser marking on backlit components

Backlit components are present in all vehicles. These include the buttons on the radio, air conditioning, and windows, and are produced with a laser through a process called selective ablation.

This laser marking technology uses a concentrated laser beam to remove one or more layers of paint until the desired color is visible. The transparent surface lights up, showing the symbol of the button or component. For this type of application, the laser beam must not remain too long on the material so as to avoid burning it.

This is why the best lasers are those with very short pulses (from 2 to 10 ns) and very high power peaks.
