A serial number on a steel part is only useful if it can still be read when the part comes back for service years later. Most shops choose between three methods: electrochemical marking, dot peen and laser. Each one will mark stainless or tool steel. The differences are in what the method does to the […]
Electrochemical marking vs. laser engraving: an honest comparison If you are specifying a permanent marking method for a production line, a workshop or a field team, the decision between electrochemical marking and laser engraving usually gets framed as a budget question. It is not. It is a question about what the mark has to survive, […]
What makes a black mark black Both electrochemical marking and fiber laser annealing produce permanent black marks on metal. Both are used in serious industrial environments. But they arrive at black by completely different physics, and that difference shows up in how the mark reads under inspection — and in what goes wrong when it […]
The traditional limitation of electrochemical marking has always been the stencil. The marking device itself is fast and portable — but if you needed to change what you were marking, you needed a new stencil, and that meant either ordering from a supplier or cutting one manually. EuMark’s dedicated stencil printer removes that constraint entirely. […]
Electrochemical marking isn’t new — the technology has been used in industrial environments since the mid-20th century. What has changed is how accessible and refined the equipment has become. Today, EuMark systems are used by small workshops and multinational manufacturers alike, for one straightforward reason: they solve marking problems that other methods create. Here are […]
