DIE Spring
Die springs are a robust type of helical compression springs consisting of rectangular wire, commonly used with die sets. 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 presses to provide consistent and reliable resistance, die springs also find use in other industries.
Die springs are manufactured from rectangular wire with rounded corners. Die springs work similarly to standard compression springs, where energy is stored when a load is applied and the spring tries to keep two components separate. A tighter spring winding yields a higher spring rate for springs manufactured from th same wire.
