Questions & Answers

01 Are Filame's online engineering tools free to use ?
Yes, all Filame engineering calculators (3D spring sizing, EN 15800 tolerances, and galvanic corrosion matrix) are completely free to use directly in the browser with no download or registration required.
02 Which standards do these calculators comply with ?
Our calculators comply with European and international industrial standards: DIN EN 13906-1/2 for helical compression and extension springs, EN 15800:2008 for compression spring manufacturing tolerances, and MIL-STD-889D / ASTM B117 for galvanic compatibility.
03 Can I directly request a quote from the calculation results ?
Yes, each tool includes a 1-click RFQ transfer button that pre-fills your exact geometric, mechanical, and alloy specifications into Filame's quote system for rapid review by our engineering department.
04 Does Filame offer custom engineering support beyond these calculators ?
Our in-house study bureau and CAD tooling team work collaboratively with clients across Europe to optimize parts for manufacturing (DFM), prototype new geometries, and resolve fatigue or corrosion challenges.
