Longer life Die Springs or High Force Compression Springs are made of pre-tempered, rectangular shaped chrome silicon wire. The springs are designed for use where high loads are required and in applications where ambient temperatures reach 475 degrees F.
The springs are stress relieved after coiling, preset and shot peened to provide maximum fatigue life. Both ends are precision ground and then powder coated with a solid colour to identify the duty range.
There are many Die Springs or High Force Compression Springs available from stock. There are four duty ranges with sizes ranging from 3/8″ OD ( 10mm ) to 2″ OD (50 mm ) and lengths from one inch to 12 inches. ( 25 to 300 mm )
The diagram below will help you specify the important parameters for your Die spring.
If you know the loading you require or if you just need further information, our technical department will be pleased to advise the springs which are available from stock.
