The Marking Method That Lives in the Spec: Electrochemical Etching for Aerospace and Medical Parts Across most manufacturing, a part number is something you add at the end. In aerospace and medical device work it is something you engineer in from the start — called out on the drawing right next to the material and […]
Both electrochemical marking and fiber laser engraving can produce permanent black marks on metal. Both are used in professional industrial environments. But when you’re standing on a shop floor deciding which system to buy, the differences matter more than the similarities. This comparison focuses on four practical criteria: mark quality, flexibility on non-flat surfaces, speed, […]
Most electrochemical marking pads use felt or foam cores. They work — but they’re imprecise about how current flows through the pad and into the marking area. The result is inconsistency: marks that look slightly different from one press to the next, uneven edges on fine text, higher electrolyte consumption. EuMark’s high-density graphite hand stamp […]
Electrochemical marks are already permanent. The oxide layer formed during marking bonds chemically with the metal surface and resists abrasion, common chemicals, and standard cleaning processes. But in aggressive industrial environments — salt spray, coolant exposure, outdoor weathering, repeated handling — even a well-made mark can degrade faster than expected. Protective oil is the final […]
The marking device and stencil are only part of the equation. The electrolyte formulation determines the chemistry of the oxidation reaction, which directly affects the color, depth, contrast, and durability of the finished mark. Using the wrong electrolyte for your metal type produces weak results. Using the right one produces marks that last. Here’s a […]
When an electrochemical mark looks wrong — fuzzy edges, incomplete fill, uneven color — the instinct is often to adjust the device setting or change the electrolyte. In most cases, the actual problem is the stencil. Stencil quality and handling have more influence over mark quality than any other variable in the process. Here’s what […]
