A solid carbide pin oscillates by pneumatic and electronic means. It is moved by two carriages in the x and y direction and strikes the material by an up and down movement. Depending on the impact frequency the marking either becomes a continuous or a single dotted line – perfect for characters, logos or two-dimensional codes, e.g. Data Matrix Code.
The force produced by the single dot marks is negligible. Due to this it is possible mark pressure sensitive, thin-walled, coated, hollow and arched work pieces. The system is suitable for almost all materials – also hardened steel!
