What is marked and where

In automotive and the metal industry, machined parts, sheet metal, castings, plastic components, harnesses and transport packaging are marked. The marking identifies the part and its batch, and is usually permanent or must withstand later processes such as cleaning, heat treatment or painting.

Typical challenges

  • Permanent marking that resists wear and later processes.
  • Metal, oily or finished surfaces, and parts with complex geometry.
  • Small 2D codes with good readability on the reader.
  • Short runs with frequent data changes.
  • Heat processes that call for special inks.

Frequently asked questions

Laser or ink for marking metal?

A fibre laser gives permanent marking with no consumables; ink is more flexible for varied surfaces and packaging. It depends on the part and later processes.

Are there inks that withstand heat?

Yes, there are CIJ inks resistant to heat up to 200 °C. This must be checked against your specific process.

Can a part be marked by hand?

A portable laser is available to mark large or fixed parts. Ask about models and marking areas.

Do you test with samples?

Yes, we always recommend tests on samples of your part before deciding.
