Laser marking with barcodes and serial numbers

Laser marking of products and electronic components

Laser marking of products and electronic components

Line and 2D codes, like serial numbers, are already used in most industries, such as (e.g. the automotive industry, medical technology, or electronics industry), in order to make products or individual parts traceable. The codes (mostly data matrix or bar codes) contain information regarding the parts properties, production data, batch numbers and much more. Such component marking must be readable in a simple manner and partially also electronically and have a lasting durability. Here, laser marking proves to be a flexible and universal tool for a wide variety of materials, shapes and sizes as well as the processing of dynamic and changing data. Parts are laser-marked at the highest speed and absolute precision, while wear is minimal.

Suitable materials for laser processing

Components, parts or products of all types of metals e.g.:

  • stainless steel, alloyed steels
  • aluminum, anodized aluminum
  • titanium, titanium alloys
  • brass
  • copper, other precious metals
  • coated metals

Components, parts or products of plastics e.g.:

  • silicone or many other plastics

Depending on requirements, metals and plastics can either be laser marked or laser engraved.


Application examples for laser marking with bar codes and serial numbers

Part labeling based on specifications:
In contrast to the design of parts in creative industries, codes and serial numbers often have to be applied to the products in accordance with customer specifications or legal requirements in industry (e.g., the automotive and supply industry, the electronics industry, medical technology, etc.). 

The marking of the parts thus does not increase the profit. This means that the marking must be as cost-efficient as possible. Here, laser marking also offers unbeatable advantages, since no setup costs or elaborate and expensive preparatory work are required. No matter whether 1 or 1000 parts - the cost per laser marking is always at the same low level.

What is the point of buying a laser for marking parts?

Automatic code and serial number generation with ERP connection
With Trotec marking lasers you can label your parts precisely. The laser systems distinguish themselves through their high service life. In addition, the included SpeedMark marking software is able to communicate with external systems such as databases or ERP systems (such as SAP) and enables a continuous code generation. However, except for a brief training by the Trotec team, no prior knowledge is necessary. You can easily laser mark your products or components either by direct input or with fully automated program sequences.

Function and advantages of laser technology

Permanent marking

  • In contrast to other technologies, you can label your parts permanently and additionally in a heat- and acid-resistant manner with the laser marking
  • Particularly important for traceability and quality assurance

Advantages of a Trotec laser

  • Product portfolio with matching fiber laser systems for all requirements
  • Flatbed systems with working surface up to 726 x 432 mm
  • Galvo work stations with working surfaces up to 620 x 315 mm
  • OEM Galvo fiber laser for integration into production lines
  • Special systems according to customer requirements

Flexible, dynamic data can be marked

  • You can mark different types of markings (codes, serial numbers, etc.) with a laser with dynamic contents without refitting or changing tools

Advantages of a Trotec laser

  • Intelligent and intuitive laser marking software SpeedMark, which can easily process data from existing ERP systems and all dynamic contents in codes

Cost-efficient production

  • Direct marking means no costs for consumables such as inks, chemicals, pastes or sprays
  • The handling and the often expensive disposal of these materials is also dispensed with
  • No pre- or post-treatment is necessary during component labeling - No tool wear

Advantages of a Trotec laser

  • SpeedMarker with a maintenance-free fiber laser as a laser work station or it can also be integrated into a production line
  • The robust mechanics of the Trotec laser systems is designed for years of intensive use with minimal servicing

Laser marking in seconds for more throughput

  • Very fast marking is possible, even of variable contents (e.g. serial numbers, codes)
  • Labeling of components with different marking contents without refitting or tool change

Advantages of a Trotec laser

  • Intelligent and intuitive laser marking software for easy operation
  • Fast and precise positioning of components using a camera system: SpeedMark Vision – Smart Adjust
  • Integration of contents from ERP data files possible.

Perfect marking results - fine tool

  • Precise and smallest geometries can be marked by laser in a highly accurate manner
  • Marking processes can be combined in order to clean the material after processing or to create a higher contrast (e.g. with data matrix codes)

Advantages of a Trotec laser

  • High-quality optics and best beam quality thanks to high-quality components
  • Camera-based component positioning for maximum precision and ease of use

Integration into production lines

  • Hardware and software integration into existing production lines possible
  • In the case of very high piece numbers, you can also integrate the component labeling into the existing production process

Advantages of a Trotec laser

  • Longstanding experience of system integration of Galvo OEM lasers in production lines
  • Software which fulfills all requirements of the interfaces with other systems

Non-contact and process-safe material processing

  • When marking the components, the material does not have to be tightly clamped or fixed
  • Time saving and consistently good results in laser marking

Advantages of a Trotec laser

  • Broad product portfolio with suitable laser system for every requirement
  • Highest accuracy of the laser marking already at the "first shot" by means of camera-supported positioning.

Robust and durable

Trotec laser machines are built for intensive use over many years and therefore have a particularly rugged design. Moreover, we only use components of the highest quality from leading manufacturers that ensure reliability and a constant high quality.
