Metal tube rollformer

Automotive industry

Fontijne Grotnes metalforming technologies are widely used in the automotive industry. Increasing specifications force companies to make products with tighter tolerances. Expanding, shrinking, rollforming are processes used to obtain tighter tolerances and higher accuracy.
Electric motor and generator housings
The production process to make housings for electric motors, alternators and generators often requires machining to bring the inside diameter and roundness to such a tolerance that the internals of the electric equipment will fit properly. Manufacturers use Fontijne Grotnes Expanders to calibrate electric motor housings over the complete length to the required tolerances, thereby eliminating additional machining operations.
Sizing and forming emission shells
Sizing and forming emission shells. These emission shells are first pre-formed on a Fontijne Grotnes Expander, then they are profiled using a Fontijne Grotnes Rollformer. After profiling the shells are sized on the same Expander to a final shape and diameter.
