Hinterkopf also makes a contribution to sustainable and economical production with the new N50.3 necking machine. As compared to its predecessor, the N40, it has ten more stations
where the shaping process can be carried out. The reason for this expansion: Ever more frequently, alloys are being used instead of pure aluminum. The harder alloys allow the production of cans with thinner wall thicknesses, which means that less material is required. However, this means that the forming process must be done in finer stages. The N50.3 does this without a problem.
