Industrial machines, watches, bottles of perfume, lighters, robots, shock absorbers, are only examples of the very numerous goods that would be useless without one or several small springs. Springs too often remain neglected; however, they play a critical role in a vast number of objects for everyday use. Due to the high mechanical and sometimes thermal or chemical stresses to which springs are subjected and their little size, springs must be made satisfy the highest quality standards. Cutting-edge sectors, such as automotive, pharmaceutical or high-tech industries place a very high a high degree of importance on the springs incorporated in their products.
