Standards-based engineering
Every number, in the open.
Springs3d isn't a black box. Every design shows its spring rate, index, Wahl correction, solid height, natural (surge) frequency and safe operating limits live, and grades its tolerances against EN 15800 / EN 13906 in standard or precision class. Compare allowable stress across material grades in one matrix to pick the right wire, not just a working one. You design on real engineering you can defend, not a mystery number.
- Live rate, index, Wahl correction, solid height and surge frequency
- Safe load / deflection / torque / angle limits
- Allowable-stress matrix across material grades, with live utilization per grade
- EN 15800 / EN 13906 tolerance grades, in standard or precision class
More in the Studio
Real-time 3D editor
Grab handles on the spring and reshape it directly — geometry rebuilds live, with zero lag.
→AI design copilot
Describe what you need in plain language, attach a drawing or CAD file, and the copilot proposes changes the calc engine verifies before they touch your spring.
→Stress & fatigue simulation
Apply load and watch stress colors, deflection and safe limits — plus cyclic fatigue life with a Goodman margin.
→Inverse design
Enter the loads and travel you need, even two operating points at once, and the studio solves the geometry and material for you.
→Optimizer & design reuse
Set goals and limits and the optimizer sweeps thousands of candidates; the reuse search finds springs you already make that fit.
→Fifteen spring families
Compression to torsion, conical to wave, belleville, constant force, garter and free-form wire parts: fifteen families, each simulated in 3D.
→Your language, currency & units
Work in Portuguese, English or Italian, price in R$, € or US$, and design in metric or imperial.
→Wire forms & CNC former
Design clips, hooks, rings and brake springs as a feed-bend-coil program — then watch a camless wire former run it.
