Dot Peen Engraving

Dot peen engraving machines work by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked. The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).

Frequency can be adjusted by controlling the speed of the X and Y axes movements. What makes SIC Marking’s dot peen marking systems so unique is the constant measurement of the electrical current between each pulse. This allows for constant, precise control of the impact consistency.
