Technology Process description

Roller Die Forming
Machinery

The roller die forming process was introduced to North America by TransForm Automotive in early 1997. The process utilizes tooling technology developed in Germany. The tooling mainly consists of a full set of rollers located in the lower die set and the mandrel mounted to the upper die set. The tooling is typically part of an entire transfer press die set. The preform is located on the mandrel and the entire spline is rolled during a single stroke of the transfer press . Depending on spline geometry, dimensional requirements and workpiece materials a single, dual or triple roller die configuration is required.

For special spline and part geometries TransForm also utilizes segment tooling technology.
