For a long time Sweden has enjoyed a worldwide reputation for precision engineering based on a unique combination of world-class research institutions, a heritage of excellence in materials science and a deeply rooted culture of quality. Precision engineering—the design and manufacture of components and systems with tolerances measured in micrometers or even nanometers—is the invisible backbone of Sweden’s advanced industries. It enables everything from the safe landing of aircraft to the precise cuts of robotic surgery and the complex optics of space telescopes.
Within the Swedish precision engineering industry there is a great deal of diversity. The ecosystem is home to huge industrial giants such as Sandvik, a global leader in cutting tools and materials technology and highly specialized manufacturers making parts for CERN’s particle accelerators and MEMS components for the most sophisticated photonic systems in the world. The following five companies are the strongest expressions of this expertise, from nanoscale silicon etching to high-tolerance aluminum casting for hypercars and micro-positioning systems for big science.
