Hydroforming technology - A-pillar

The advantages offered by IHU-formed components are utilized and highly regarded in many areas of industry. 

Especially in the automotive industry, the manifold advantages of IHU technology are highly valued – from extreme forming degrees, high lightweight construction performance, stiffness, to design possibilities and special precision requirements and all the way through to excellent operational strength.

Component: A-Pillar

Probably the most demanding task for an IHU component is to absorb the entire weight of the vehicle in the event of a crash. An impressive example of this is a one-piece A-pillar for a convertible that has to withstand enormous loads in the event of a rollover. In order to achieve this – also at reduced weight and reduced number of components – a tailored tube with different wall thicknesses and variable diameter is opted for as the primary material.
