Conventional manual labelling of metallic objects
By using Emil Otto metal etching pens, heavy metals and aluminium can be labelled, identified or marked quickly and easily. Time consuming engraving or stamping of characters and/or numbering is no longer necessary. Emil Otto metal etching pens have proven themselves, also for marking hardened and thin-walled metals, in toolmaking, for labelling assembly parts, for testing and inspection work and a wealth of other applications.
