What is the maximum force that a Die Spring can achieve?

  • Die springs are designed for situations where considerable loads are applied in a very confined space, particularly in the case of press dies
  • The use of chromium-vanadium/CrSi steels in accordance with SAE 6150 permits maximum loads to be combined with a long service life
  • Die springs are classified in groups according to diameter. However, with this system, die springs with the same mounting dimensions can be selected in accordance with different load requirements
  • This increases the durability of stamping, bending and other dies
  • Each group of die springs is arranged according to a color code system, in order of increasing load. Die springs in accordance with the ISO 10243 standard
  • The solid length is approx. Ln; here the maximum forces are achieved
  • For frequencies greater than 1000 strokes/minute, the following values should be observed in the case of springs with the designation 0R....
    Green: 25% to 30% compression
    Blue: 20% to 25% compression
    Red: 15% to 20% compression
    Yellow: max. 15% compression

Springs with the designation 0ST... have the following color codes and load types

  • Medium loads = Blue
    Medium heavy loads = Red
    Heavy loads = Gold
    Extra heavy loads = Green
