How to Get a Sample
- Catalog items (≤5 pcs): free you pay only the shipping cost
-Custom samples: $50 sample fee, fully refundable (deducted from your future order)
-Typical turnaround: 5–7 business days
-Every sample includes an inspection report and full dimensional data
Reverse Engineering
Have a spring but no drawing? Send us 3–5 sample pieces. We analyze the material and performance and deliver matched prototypes within 7 days.
What We Can Prototype
- Custom shapes: conical, barrel, double-torsion, and more
- Materials: high-carbon steel (65Mn/70Mn), stainless (301/302/304/316), alloy steel (50CrV/55CrSi/60Si2Mn), and custom materials
- Surface treatments: electroplating, powder coating, electrophoretic coating
- Extreme-condition springs: high-temperature and cryogenic
From Prototype to Production
Once you approve the sample, we move into mass production using the same validated tooling and process — so what you tested is exactly what you receive at volume.
