Die Springs

Die Springs are heavy duty metal compression springs manufactured using round wire, specifically designed to be used as Die Springs or as heavy duty coil springs in any high stress, heavy load application. Die springs are used primarily in die machinery. However, they are also well-suited for many applications where high-static or shock-load stresses are required, or when maximum cycle-life is important. Rectangular wire is employed to reduce the solid height and increase the space efficiency of the design. We produce die cut springs using both round and rectangular wire.

Features & Benefits of Die Springs

1. Shot-peened for extended life.
2. Preset to prevent length loss in operations.
3. Powder Coated for corrosion resistance and color coded for ease of identification.
4. Closed and Ground Ends to provide appropriate squareness and adequate large bearing surface and will stand on either end.

Applications of Die Springs

Die Springs are not solely used in dies but applications such as oil and gas drills, clutches, brakes, farm machinery and aircraft mechanisms. They are ideal for use as heavy duty compression springs for any high stress, heavy load application.

Tips for Selecting and Using Die Springs

1. Determine if springs will be used for short run, average cycle long run, rapid cycle or extra stress.
2. Use as many springs in the die as space permits with the least amount of deflection.
3. The more rapidly a spring is cycled, the greater the need to operate within the ideal operating range.
4. Make sure hole and rod sizes are properly matched with the spring. Faulty spring guidance will cause buckling and possible spring failure.
5. Preventive maintenance on dies should be performed on a regular basis and die springs should be replaced at appropriate intervals to prevent downtime.
6. Replace all springs in a die at the same time. This will insure an even distribution of the load.
7. Do not rework die springs by grinding the inside or outside diameter or by cutting off coils. This could result in premature spring failure and possible die damage.

Measuring Die Springs

1. Measure the Hole Diameter (a.k.a Outside Diameter)
2. Measure the Rod Diameter (a.k.a Inside Diameter)
3. Measure the Free Length (no load on the spring)
4. Measure the Wire Size (both width and thickness)
