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
