✈️ In aerospace, "good enough" isn't good enough.

When a spring is designed into an aircraft system, customers need more than performance—they need proof.

That's why John Evans' Sons maintains certifications that aerospace manufacturers trust:

✅ AS9100 Certified
✅ ISO 9001:2015 Certified
✅ ISO 13485:2016 Certified

Our constant force balance springs are used in aerospace applications throughout the industry.

Certifications aren't just paperwork.

They're the documented processes, traceability, inspections, and quality controls that help ensure every spring performs as expected.

America's First Springmaker.
Founded in 1850. Trusted today.

Every ounce matters in aerospace robotics.

From deployable antennas and robotic arms to positioning systems and sensor deployment mechanisms, engineers need components that deliver reliable performance without adding unnecessary weight.

That's where John Evans' Sons helps.

Our Constant Force Springs provide smooth, controlled force throughout the full range of travel, helping reduce system complexity and eliminate bulky alternatives.

Combined with our Precision Wire Forms—manufactured from aerospace-grade materials such as Inconel®, Beryllium Copper, and stainless steel—we help engineers build lighter, more dependable systems for demanding applications.

When components work together, performance improves.

When they're manufactured to exacting standards, reliability follows.
