Die springs are designed to withstand high load and ambient temperatures of up to 475 degrees Fahrenheit. These springs are able to withstand a greater degree of environmental stress as heat plays an important role in load-loss
Die springs are a very robust hybrid version of a compression spring, it made of pre-tempered, rectangular-shaped chrome silicon wire. Maximum fatigue life is achieved through stress relieving after coiling, followed by the springs being preset and shot-peened. The ends are then precision ground and the entire spring is powder coated to give it sizing identification and finish. A colored stripe is added to identify duty range of each spring. The result is a heavy-duty spring designed to provide excellent quality, value and service under intense conditions.
