Dimensions

Die Springs DIN & ISO are arranged 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.

Materials

Chromium alloys for highly dynamic applications at high temperatures.
Original Raymond ®Die Springs.
High-quality chrome-vanadium steel according to ISO-10243.

Heat

The maximum operating temperature is 240°C. The identification colour remains intact at these temperatures. With average material strengths of ~600N/mm², the force loss at this temperature is approx. 10%.

Maximum Force

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 chrome alloys permits maximum loads to be combined with a long service life.

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
