Rotary swaging is a high-precision cold-forming process in which several die segments oscillate radially and simultaneously strike the workpiece in rapid succession. These repeated, incremental forming steps cause the material to flow in a controlled manner, enabling the production of dimensionally accurate components with tailored mechanical properties. The process accommodates a wide range of external and internal geometries and offers considerable design freedom for both visible and structural parts.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Process Principle<\/strong><\/h2>\n<\/div>\n<\/div>\n
\n
\n

In rotary swaging, multiple die segments strike the workpiece at frequencies exceeding 1,000 strokes per minute. Each stroke produces a small, incremental forming step of typically 0.25 to 1.5 mm. This incremental forming approach reduces forming forces, ensures excellent formability, and promotes homogeneous material flow. During the process, the workpiece undergoes cold working, leading to an increase in strength and fatigue resistance.<\/p>\n

The process can be performed with stationary or rotating workpieces, and with or without internal mandrels, depending on the required geometry.<\/p>\n<\/div>\n<\/div>\n
