Radial Forming & Crimping Process

radial forming and radial crimping process

Radial Forming

Radial forming is a process in which parts are formed by actuating a system of dies radially toward the center of the workpiece. Dies are moved radially inward by a wedge actuation system which converts axial force into radial force. Radial forming is well suited for producing squares, hexes, coarse splines, stakes, and other symmetrical geometry on shaft components. The process is also well suited for mechanical fastening by crimping and for crimping vibration resistant nuts.

Benefits of Radial Forming

  • High accuracy and repeatability
  • No material waste
  • Easily adjustable
  • Fast cycle times
  • Small machine footprint
  • Quick change tooling design

radial forming processRadial Forming

Radial forming can be used to deform a round or pre-shaped blank into a more complex form with zero material waste. As the dies plunge in, material is formed radially inwards and upwards between the dies. Shapes that can be formed include high module splines, polygons, square, hex and other similar axial forms.

radial crimping processRadial Crimping

Radial crimping can be used to form vibration resistant nuts for the aerospace and automotive industry by crimping finished nuts into a non-round form. Nuts can be crimped with anywhere from 2 to 6 dies in materials such as Inconel, Waspaloy, titanium, alloy steel and stainless steel. Nuts can be crimped on round locking collars and can be oriented to be crimped on the flats or other features.

Components such as rings of a dissimilar material or a bearing can be crimped onto a shaft to generate an assembly locking feature. An undercut is typically cut into the shaft and the ring or bearing can then be crimped permanently into the undercut.
