Camshafts for generators and cars usually manufactured from solid or hollow-cast iron.

As camshaft structure development is to achieve lower weight and lower costs.

Our assembled camshafts using the IHU joining process (internal high-pressure forming) are between 20% and 30% lighter than solid camshafts but equally transmit very high dynamic torques.

With the IHU joining process, it is possible to combine high-grade, functionally appropriate cam materials with cost-effective materials for tubular and other less stressed additional parts.

In combination with automated production systems built-up camshafts are costs competitive as compared conventionally designed shafts.

Our IHU joining technology, by means of numerically controlled axes, enables a very precise, force-free axial and radial positioning of the components on the tube. Then it follows the pressure build-up for the actual pressure fit. After the joining process all the important geometrical features of the camshaft are measured with an optical measuring instrument. The results are then fed back automatically into the NC control system of the joining unit in order, if necessary, to correct the position values during the process. This enables very precise geometrical tolerances of the cams to be reliably achieved together with grinding allowances and thus production costs in the subsequent processes can be reduced.
