How does dot peen equipment work?
Dot peen permanent marking machines work by electromechanically striking the surface of the part being marked with a carbide needle. The result is a series of points for creating numbers, text, logos and codes of a 2D data matrix. Each such point is the result of a pulsed current passing through the solenoid, striking the magnet against the surface, and then returning the needle to its initial position, waiting for the next pulse. Since each pulse occurs for only a fraction of a second, the entire code of a 2D data matrix, 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 dot peen marking systems so unique is the constant measurement of electrical current between each pulse. This allows constant, precise control of stroke consistency.
