Compression Spring, SAE 6150 rectangular material with round edges

Die springs are made specially for use where high load is required in a confined space; eg Die sets. The high demands placed upon these springs is a result of the high frequencies with which present dies are charged. The use of high quality chrome vanadium steel (SAE 6150) combines maximum load with long life.

Our range of die springs is composed of 8 groups by diameter. In this way it is possible to select springs of different load characteristics for the same tooling already adapted for pressed parts, resulting in a longer operating lifetime for your dies and die sets.

Each group of springs is divided into a rising load range and can be identified by a color coding system:

Medium - Blue
Medium Heavy - Red
Heavy - Gold
Extra Heavy - Green

Recommended Deflection for high frequencies and a minimum life cycle of 2 million strokes. Efficient operating range will be:

Blue - 25-30% of the free length
Red - 20-25% of the free length
Copper - 15-20% of the free length
Green - 15% of the free length
