How Process Selection Impacts Overall Production
Industrial Direct Part Marking
Selmsdorf, 18.06.2026 (PresseBox) - Permanent readability is only one part of the requirements for industrial marking. Just as important is how the chosen marking process affects manufacturing workflows, quality assurance, and traceability. Whether it proves its value over the long term depends not on the mark alone, but on how it fits into the overall production process.
An example from electronics manufacturing illustrates how the choice of a marking process can affect day-to-day production: On a production line for sensor housings, Data Matrix codes can no longer be read consistently at an inspection station. Individual parts have to be checked manually or removed from the line, increasing effort and delaying production. Root cause analysis reveals that the scanner is not the problem. The issue lies with the marking itself. The code, applied using an ink-based method, gradually loses contrast as it moves through the process due to cleaning steps and mechanical stress.
Similar situations occur across industries, from medical technology to automotive and electronics. The takeaway is clear: marking is not an isolated step but an integral part of the overall manufacturing process. The mark determines whether automated production steps and inspections run reliably and whether products remain fully traceable. "What matters is not readability immediately after marking, but its stability throughout the entire process chain and beyond. For products subject to regulatory requirements, this extends across the full product lifecycle," summarizes Damian Zawadzki, Product & Application Manager at FOBA.
Ink printing, pad printing, and labeling are well-established and cost-effective solutions in many applications. They offer advantages for specific color and design requirements or extremely high line speeds, such as in the beverage industry. However, they also have limitations, as the marking is created by applying an additional layer to the surface. Factors such as cleaning, abrasion, UV exposure, or temperature fluctuations directly affect this layer, compromising contrast and readability.
Thinking Beyond the Mark: Workflow Instead of Isolated Steps
With this in mind, laser technology for direct part marking (DPM) is gaining importance, particularly in medical technology, electronics, and the automotive industry. Rather than applying a mark to the surface, laser marking generates it directly within the material, for example through annealing on metals or color change in plastics.
Modern laser systems enable precise, material-friendly marking for demanding applications, as Damian Zawadzki confirms: "In our application laboratories, we test a wide variety of products for our customers every day. Innovations in laser technology make it possible to mark even sensitive materials with high contrast and minimal heat input. In addition to the laser source, selecting the right parameters is critical for marking quality." Especially with engineering plastics used in sensor housings or connectors, new UV lasers can produce high-contrast codes even on low-absorption or dark surfaces.
But laser marking differs from ink- and label-based processes in more than just how the mark is created. The real distinction is in the process design: At FOBA, for example, laser marking is part of an end-to-end workflow, with automatic mark alignment, verification, and code reading.
Here is what that looks like in practice: The vision system precisely locates each part, the content is aligned with high accuracy, and results are inspected immediately after application. The camera system and the MarkUS software compensate for tolerances and monitor quality criteria during production. A key factor in the stability of this automated process is the integration of the vision system directly into the marking head. "Think of the camera and the laser beam as sharing the same line of sight to the product. This avoids distortions and achieves extremely high reliability," explains laser expert Zawadzki. The system is particularly easy to operate, as both the laser and the vision system are controlled through the same software interface.
Is Switching to Laser Marking Worth It?
Switching to laser marking pays off when you look at the bigger picture: An end-to-end marking workflow, such as the FOBA workflow described above, has a positive impact on production. Readability remains stable, manual interventions are reduced, and scrap rates decrease. At the same time, traceability improves through automated reading, inspection, and processing of marking data. Companies benefit not only from reliable marks but also from robust traceability data across the full product lifecycle.
In addition, there are ongoing savings: less rework, less unplanned downtime, and more stable inspection processes reduce costs. Refilling, drying times, and the need for consumables are also eliminated, with additional sustainability benefits.
The move to laser marking is often initially evaluated from a cost perspective. Indeed, the upfront investment is typically higher than for conventional printing solutions. The benefits become clear when the entire process is taken into account. "Laser marking is often underestimated because it initially appears more expensive," says Zawadzki. "In practice, however, it proves its worth especially where processes must run consistently and where identification is a critical factor."
The Bigger Picture: A Process Decision
Choosing a marking method is a process-level decision with implications for quality, cost-effectiveness, sustainability, and the long-term viability of the entire production operation. The sensor housing example illustrates how quickly marking can shift from a seemingly simple process step to a limiting factor in manufacturing.
Whether switching to laser marking is worthwhile cannot be determined by investment costs alone. Printing and labeling remain a valid choice for many applications. However, once marking becomes a critical component of process quality, laser technology offers clear advantages. This is especially true when parts must be permanently traceable, codes must remain readable, and workflows must remain stable.
For companies considering this step, a structured approach is recommended: First, the actual requirements should be clearly defined, not just marking quality but also production stability, automation, and regulatory compliance. From there, existing processes can be systematically evaluated: Where do they perform reliably? Where do limitations appear within the process or over the product's service life?
Before making the transition, companies should test under real-world conditions, ideally with application tests on original parts that reflect the whole process chain. This is the only way to determine whether a new process actually achieves the required stability.
