Rotary swaging
Rotary swaging is a precision process for the non-cutting forming of tubes, rods and other rotationally symmetrical workpieces.
Radial forging
Radial forging is an incremental forming process for cold, semi-hot and hot forming of complex workpiece profiles.

How Rotary Swaging Works
Rotary swaging is a precision process for the non-cutting forming of tubes, rods and other rotationally symmetrical workpieces.
For infeed swaging, the workpiece is moved in an axial direction continuously through the oscillating dies, while the dies rotate around the workpiece. There is a flat calibration plate in the swaging head between the hammer and die.
For plunge swaging, the dies perform a radial closing movement, in addition to oscillating radially. The closing movement is achieved using wedge-shaped hammers and calibration plates. Plunge swaging makes it possible to reduce the cross-section between the ends of the workpiece.
It is possible to combine the two variants of the process and use both infeed and plunge swaging. This involves the dies closing radially, while the workpiece is fed in axially, superimposed on top of the closing movement. This can be used to achieve undercuts of any length.
Advantages
- Short processing times
- Tight tolerances
- Smooth grain flow
- High-quality surface
- Savings on material
- Weight reduction of the workpiece
- Fewer production steps
- Environmentally friendly
How Radial Forging Works
Radial forging is an incremental forming process for cold, semi-hot and hot forming of complex workpiece profiles.
Four mechanically driven dies arranged on one plane radially form the workpiece. The workpiece is actively set into a defined rotation by the chuck head.
The hammer stroke is delivered by high-speed eccentric shafts. The adjustment unit between the eccentric shaft and the die gives you exact positioning for producing both stepped and conical workpiece profiles.
Power is transferred via an electric motor, gearbox, eccentric shafts and ram units. Particular attention has been paid to the diameter adjustment system. An advanced, patented system guarantees high-precision adjustment of the die over large ranges.
