The S19 and S25 are a further evolution of the CNC technology of dot matrix marking machines which solves many marking problems on components of different shapes, in plastics, metal, glass etc., and guarantees the quality of your product. The marking unit is of simple and sturdy design to achieve high productivity at low cost. The carbide stylus can engrave metals up to 62 HRc hardness and is designed to mark both concave and convex irregular components. Electric vibrations provide an outstanding working flexibility and an unusually noiseless operation. The very weak impact of stylus will not damage molecules of marked parts.
