Airbag Components for passenger or side airbag systems

Airbag components applied to passenger or side airbags are manufactured out of one tube with the voestalpine HTI rotational forming technology. For this process steel as well as aluminium tubes could be used.
The rotational forming technology enables the adjustment of flexible wall thicknesses and is especially qualified for flexible lengths for diameter of 20 to 200mm.
Due to this technology the number of required forming tools is compared to other technologies as stamping or pressing low. That offers a huge potential for cost saving.
Furthermore the rotational forming process guarantees a comprehensive material coating in respect of durability, material structure and grain boundaries (homogeneity) . This leads to the demanded bursting behaviour and enables besides others the graduation of the strict airbag test procedures of the automotive industry.
