The dot peen marking equipment works by mechanically striking a carbide needle against the surface of the part being marked. The result is a series of dots used to create numbers, text, logos, and 2D data matrix codes. Each dot is the result of an electrical pulse passing through a solenoid, which strikes a magnet towards the surface and then returns the needle to its starting position, awaiting the next pulse. Since each pulse occurs in just a fraction of a second, an entire 2D data matrix code, for example, can be completed in a few seconds (depending on the size).
The frequency can be adjusted by controlling the movement speed of the X and Y axes. What makes SIC Marking systems with dot peen technology so unique is the constant measurement of the electrical current between each pulse. This allows for continuous, precise control over the consistency of the impacts.
