Wire and the resulting products, such as springs, screws and cables, are necessary for the functioning of technical systems. However, products made by the wire and wire-processing industry also play a major role in everyday life. We just need to remind ourselves of paperclips, ballpoint pen springs, key rings and of course power cables. Progress in areas such as transport and power engineering are closely related to ongoing developments in the wire and wire-processing industry, and the increasing miniaturisation, which can be observed in so many areas of technology, is only possible with the help of suitable wire products. These are based on wire which is made from a variety of metals and has a diameter between 0.5 and 2.5 mm. The prefix “micro” is applied to anything below 1 mm in all three dimensions. While the dimensions of micro-components are getting smaller and smaller, we can see a steady increase in requirements on technical properties and thus also on the relevant production equipment and its components.
