Peterson Spring - Technical Products Center Datasheets for Die Springs

Die springs are a robust type of helical compression springs consisting of rectangular wire. For the same value deflection, die springs carry 30% more load. These springs are designed to carry very high compression loads in hostile environments. Made mainly for punch press to provide consistent and reliable resistance, die springs also find use in other industries.
