Custom Spring Manufacturing Engineering Review Before Production Prototype & Small MOQ Available Fast Quotation & Global DeliveryOverview
Elgiloy is one of the most frequently specified materials for high-performance spring energizers. At Handa Spring, we combine material expertise with precision manufacturing to deliver springs that perform consistently in demanding sealing applications.
While many customers already specify Elgiloy for their projects, our engineering team also provides material verification, alternative recommendations, and manufacturability reviews before production begins. We don’t just manufacture springs—we ensure the material and the design work together to achieve the required spring force, fatigue life, and corrosion resistance.
Whether you have detailed drawings or need engineering support, Handa Spring delivers custom Elgiloy spring energizers with the right combination of material knowledge and manufacturing capability.
Spring Types
Each spring type has different manufacturing characteristics. The following overview highlights the
key differences in forming method and tooling requirements.
Manufacturing Method: Precision wire forming
Manufacturing Method: Precision strip forming
(U Spring / V Spring)
Manufacturing Method: Precision stamping & forming
Manufacturing Method: Precision wire forming
Manufacturing Method: Precision stamping & forming

Tooling & Manufacturing
Different spring types require different manufacturing methods. The table below shows which spring
types can be produced without dedicated tooling and which require custom tooling development.
| Spring Type | Manufacturing Method | Tooling Status |
|---|---|---|
| Canted Coil Spring | Precision wire forming | No dedicated tooling required |
| Garter Spring | Precision wire forming | No dedicated tooling required |
| Helical Spring | Precision strip forming | No dedicated stamping tooling |
| Cantilever Spring (U / V / Detached Leg) |
Precision stamping & forming | Standard tooling for common sizes Custom tooling for new profiles |
| Full Contact Spring | Precision stamping & forming | Standard tooling for common sizes Custom tooling when required |
Tooling options explained: For wire-formed springs (Canted Coil, Garter), no tooling is required, enabling fast prototypes and flexible customization. For strip-formed springs (Cantilever, Full Contact), we maintain a large library of existing tooling for common sizes, and can develop custom tooling efficiently for new profiles when required.
Manufacturing
Selecting the right material is only the first step. Consistent spring performance depends on
manufacturing capability, tooling, and process control.
At Handa Spring, we manufacture finished spring energizers—not raw material. Every production stage is controlled to achieve the required spring force, dimensional accuracy, and repeatability.
Every spring is manufactured according to customer drawings or application requirements. We support both standard dimensions and fully customized spring geometries.
For U Springs, V Springs, Detached Leg Springs and Full Contact Springs, we maintain an extensive tooling library covering many commonly used profiles. This reduces tooling cost and shortens lead times.
When existing tooling does not match customer requirements, our engineering team develops dedicated tooling for new spring profiles, supporting stable production from prototype through volume manufacturing.
Wire-formed spring types such as Canted Coil Springs and Garter Springs can be manufactured without dedicated tooling, allowing fast prototype delivery. For strip-formed springs, prototypes are optimized using existing tooling whenever possible.
Spring force is one of the most critical parameters affecting sealing performance. By adjusting geometry, material condition and manufacturing processes, we can customize spring force to meet customer requirements.
Additional processes available include precision welding, heat treatment, ultrasonic cleaning, passivation, spring cutting to specified lengths, and spring force testing—selected according to project requirements.
Manufacturing feasibility is reviewed before quotation to identify tooling, forming, and tolerance considerations at an early stage.

No sales gatekeepers between you and our engineers
Over the years, Handa Spring has supplied custom Elgiloy spring energizers to seal manufacturers, engineering firms, and equipment OEMs across North America, Europe, and Asia. Our objective is to become part of our customers’ engineering process—from prototype development through long-term production.
Engineering Experience
Over years of manufacturing custom spring energizers for customers worldwide, Handa Spring has accumulated practical experience
across a wide variety of spring geometries, materials, and production requirements.
Supporting customers across aerospace, semiconductor, energy, medical equipment, analytical instrumentation, and industrial sealing applications. Our team has worked with both large OEMs and specialized seal manufacturers on custom Elgiloy spring projects with varying volume and performance requirements.
Direct communication between customers and engineers helps resolve technical questions efficiently throughout the project. Video meetings and drawing reviews are available whenever required, with no sales gatekeepers in between.
Questions regarding manufacturing feasibility, lead time, tooling, or spring design are reviewed quickly by our engineering team to reduce project delays and keep production on schedule.
Support continues beyond production through technical consultation, repeat orders, process improvements, and future design optimization. We aim to be a long-term manufacturing partner, not just a spring supplier.
These factors often have a greater influence on final spring performance than material selection alone.
