Mastering superalloys, titanium, and advanced coiling. We deliver custom high-precision springs with 100% material traceability to ensure absolute safety for mission-critical aerospace systems.
Industry Overview
In aerospace engineering, component failure is not an option. At Hershey Spring, we don't just manufacture parts—we manage risk. To fight thermal creep in engines, high-frequency flutter in airframes, and tight space constraints, we maintain a strict Aerospace Manufacturing Standard. From raw material selection to final surface treatment, we ensure our custom high-precision springs deliver maximum reliability under extreme flight conditions.
Application Coverage
Propulsion: Fuel metering valve springs, turbine seal ring springs, thrust reverser actuation springs.
Landing Gear: Shock strut springs, brake return springs, locking mechanism springs.
Airframe & Interior: Door latch components, seat adjustment mechanisms, overhead bin gas spring components.
Avionics & Controls: Cockpit instrument switch springs, flight control stick return springs, circuit breaker springs.

Industry-Grade Materials
Titanium Alloy）: Offers an excellent strength-to-weight ratio for a 40%–50% weight reduction compared to steel springs, plus complete corrosion resistance.
（17-7 PH Stainless Steel）: A precipitation-hardening steel combining high tensile strength with excellent fatigue resistance under high-stress thermal loads.
Industry-Focused Processes
Utilizing fully automated CNC machinery to ensure extreme consistency in spring index and pitch, meeting aerospace-grade tolerances.
Strict control of surface scratches and tool marks to prevent them from becoming initiation points for fatigue cracks.
Durability & Reliability Enhancements
- Shot Peening
Creates surface compressive residual stress to significantly extend fatigue life and stop micro-crack growth.
- Hot Pre-Setting
Executed at high temperatures to eliminate initial creep, ensuring zero height loss under continuous operational stress.
Mechanical/Functional Customization Options
- Weight Reduction Design
By utilizing high-stress materials and variable pitch design, material usage is minimized while still meeting load requirements.
- Space Optimization
Providing double load in limited space via multi-layer nesting
(Saving 50% axial space compared to coil springs
Qualification Certification Obtained
FAQ
We implement a 100% material traceability system. Every batch of raw material is registered with a unique Heat Number upon arrival and tracked throughout production. Upon delivery, we provide complete Mill Test Certificates and Certificates of Conformance (COC), ensuring every spring is traceable back to the steel mill.
Absolutely. We manufacture Titanium (Gr.5 / Beta-C) springs. Compared to steel equivalents, our titanium solutions offer a 40%-50% weight reduction. We master the specific coiling and heat treatment parameters for titanium to balance the dual needs of lightweighting and high strength.
For aerospace applications, Shot Peening is a standard process we use to induce compressive residual stress, significantly inhibiting fatigue crack initiation. Additionally, we offer Hot Pre-setting to eliminate initial set, ensuring zero height loss over the component’s entire lifecycle.
Beyond standard dimensional and load reports, our lab is equipped with fatigue testers and salt spray chambers. Upon request, we can provide Fatigue Life Reports and Salt Spray Test Reports (96h+) to validate reliability with real-world data.
