Marking with Barcodes
Datamatrix Codes & Serial Numbers

Laser marking of products and electronic components

Laser marking of products and electronic components

Line and 2D codes, like serial numbers, are used in a wide range of industries. The automotive, medical technology and electronics industries use these markings for product and part traceability. The codes, mostly data matrix code or barcode, contain information regarding the parts properties, production data, batch numbers, and much more. These component markings must be simple to read, including electronically, and have lasting durability. Here, laser marking proves to be a flexible and comprehensive tool for a wide variety of materials, shapes, and sizes, as well as the processing of dynamic and developing data. This technique allows for parts to be laser-marked at the highest speed with absolute precision, and minimal wear.

Laser marking of products and electronic components

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

and 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.). 

Component marking does not increase the profit, therefore it must be as cost-efficient as possible. Laser marking does offer the advantages of no setup costs, and no complicated, expensive, preparation. Whether the job is 1 part or 1000 parts, the cost per laser marking remains low just the same.
