Do you already use marking systems or do you have your parts marked externally?
In this article, you can get some interesting input about the different procedures, as well as their advantages and disadvantages.
The most widespread processes
When it comes to the topic of part marking, the key term “laser marking” pops up in many of our minds. This is justified, as lasers can be used to mark a wide variety of materials and surfaces extremely quickly and easily. In addition, most systems are quite easy to programme.
So is laser marking the undisputed solution? Not quite. Even though prices have dropped considerably in recent years, a five-figure investment is still required for a high-performance laser system. For some time now, scribing or needle embossing machines have established themselves as a much more cost-effective alternative. Apart from the price, these systems also have the advantage that no protective devices are required for their operation. For the marking of individual workpieces or small series of up to a few hundred pieces, corresponding machines are also used successfully in many companies.
Compromises in efficiency and process reliability
Whether laser or needle marking machines – with both systems, part marking takes place in a separate work step. Each part is placed or clamped in the marking station after processing. This means: additional, manual parts handling, sometimes combined with additional repacking or transport.
And it is not only those responsible for QA who know that every manual activity reduces process reliability, as every employee, no matter how reliably they work, can make a mistake.
True to the motto: Complete production on the machine, these disadvantages can be completely eliminated.
In the table below you can see a list of the different methods, as well as the associated advantages and disadvantages. This overview table will help you choose the most suitable marking method.
