INDUSTRY NEWS Stepping forward together...


T


he step-by-step shaping of a tube end or of a tube, has been made possible by the newly developed


procedure for processing high- strength and ultra-high-strength materials. This revolutionises manufacturing, particularly in industrial applications where the requirements are set ever higher. And, where straight tubes are  


Incremental tube shaping can be used for weight reduction purposes in the automotive industry, for example. A wide variety of products, manufactured with this new type of process, can be exposed to heavier loads and are ever lighter.

Hydroforming for example, could be such a process. For this, a tube is pre-
