    10 Tips For Die Spring Success

    1. Consider the spring design options at an early stage.
    2. Ensure to work within the physical limits of the springs before the die is built
    3. Preload each spring when assembling to avoid shock loading, to avoid spring failure.
    4. Do not overlook possible damage from, heat, corrosion, metal chips.
    5. Consider if buckling maybe a problem
    6. Ensure the spring is kept square.
    7. Preventative maintenance should be scheduled.
    8. Replace all spring units at the same time.
    9. If a die spring does fit – avoid modifying but instead get a correct size replacement.
    10. Do not over stress / overload this will reduce the springs life considerably.

    For help and guidance contact Davies Springs at an early stage.

    Q. Why are the springs coloured:
    A: If they have to be replaced – it is easier to know what to replace the old ones with.
