Custom Machined Super Elastic Nitinol Push Rod with Spring Component - Built to Print

Q: What material options are available for this nitinol push rod with spring?
A: The main shaft adopts nitinol super‑elastic alloy. Spring and base materials can be selected according to your drawing requirements. Stainless steel alternative is also available.

Q: Can we customize shaft diameter, spring parameters and overall length of the push rod assembly?
A: Yes, shaft diameter, spring wire diameter, spring pitch, base dimension and total assembly length can all be customized based on customer drawings or physical samples.

Q: What is your standard dimensional tolerance for this nitinol push rod assembly?
A: Our standard production tolerance is ±0.02mm. Higher precision requirements can be achieved after technical drawing confirmation.

Q: Will the spring lose elasticity after long‑time reciprocating movement?
A: We select high‑quality spring raw material and optimize heat‑treatment process. Fatigue resistance meets general instrument operating cycles. Special high‑cycle working conditions need to be specified on drawings.

Q: Do you provide sterilization service for this push rod assembly component?
A: These are precision metal semi‑finished parts. We do not offer sterilization service. Customers shall complete sterilization before final end‑use application.
