Spring Index - Effect on Cost

  • Apr 23, 2024
  • 1 min read


The Spring Index is the ratio between a spring's mean coil diameter and its wire diameter. Typically, our engineering team follows a guideline: a Spring Index ranging from 4 to 12 is considered ideal. Venturing beyond these boundaries necessitates additional considerations before manufacturing.


Potential effects of an index outside of the 4 to 12 limits:

  • Longer machine setup time = higher cost

  • Slower production rate = higher cost

  • Accelerated tool wear = higher cost

  • Squareness issues = fit/function problems
