Beschreibung
Zusammenfassung:	A permanent invisible magnetic marking and positioning system of unfinished steel rods, spring steel bars, workpieces, and the like. A midpoint or center of the rod, bar or workpiece is automatically located and a high-energy pulse is applied for an embedded magnetic marker in the workpiece. Meanwhile, the magnetizing heads can also be repositioned to various points on a workpiece for imparting manufacturing and product identification data. In the case of leaf springs, the center of a spring steel bar is located a magnetic marker is embedded there. A high-energy rectangular pulse imparts a permanent invisible magnetic marks and data. The embedded indicators having peak magnetic strength allow manual or automatic positioning for perfect alignment in bending, tapping and other forming processes.
