HEAVY DUTY DIE SPRINGS
Heavy duty or die springs are specially for use where
high load is required in a confined space, eg. Die sets.
The high demands placed upon these springs are the result of the
high frequencies which dies are charged.
The use of high quality chrome vanadium steel (SAE 6150) combines
maximum load with long life.
The SPEC 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
Our Die Springs are available in 2 types:
US Standard and ISO.
The biggest differences are the colours and the higher tolerance
standard of the US Standard. This makes the US standard more
Both types can be used as an alternative.
