Among the very numerous items that necessitate one or several small springs to work efficiently, one can see bottles of perfume, robots and industrial machines, watches, lighters, shock absorbers. Although they are usually disregarded, springs play an essential role in a large number of ordinary objects. The multiple kinds of stresses to which springs are subjected combined to their small dimension require manufacturing processes to conform to the highest quality standards. Cutting-edge sectors, for example automotive, pharmaceutical or high-tech industries place a very high priority a high degree of importance on the springs that make up their products.
