Custom Springs for Contract Manufacturers

Built to Your Specifications. Delivered to Support Your Customer.

At Wermke Spring Manufacturing, we manufacture custom springs and precision wire forms built directly to your specifications and backed by ISO 9001:2015–certified processes.

Many of our customers are not building finished products. They are producing components, sub-assemblies, and systems that integrate into a larger design. Their priority is straightforward: meet their customer’s requirements, stay on schedule, and deliver consistent quality.

That’s where we fit.

We manufacture the spring components that go into your assemblies so you can deliver complete, accurate builds to your customer without disruption.

We build to your drawings. We manufacture to your specifications. We deliver repeatable results you can rely on.

Built for Custom Manufacturing Environments

Custom manufacturing often requires sourcing components outside your core capabilities. Springs and wire forms are not standard machined or molded parts. They require specialized materials, forming processes, and handling to perform as intended.

Wermke Spring manufactures:

Compression springs for controlled force and spacing
Torsion springs for rotational and actuation requirements
Extension springs for tension-based applications
Custom wire forms for retention, positioning, and mechanical support

Every component is produced to your defined dimensions, load requirements, tolerances, and material specifications. No interpretation. No redesign. Just precise manufacturing to print.

Supporting Your Work Across Industries

We support a wide range of manufacturing environments, including:

Contract manufacturers and sub-assembly builders
Plastic injection molders
Machine shops and CNC manufacturers
Metal fabricators and component suppliers
Engineering and product development teams

In many cases, our components are one part of a larger assembly where fit, function, and consistency matter more than visibility. Whether the end application is known or not, the requirement remains the same: the part must perform as specified.

Our role is to ensure that it does.

Material & Manufacturing Capability

Spring performance is driven by material selection, forming precision, and stress management during production.

We manufacture using a wide range of materials based on your specifications, including:

Wire diameters typically range from 0.009” to 0.625”, depending on the part and material requirements.

All components undergo controlled stress-relief processes after forming to ensure dimensional stability and consistent performance. When additional finishing or processing is required, we coordinate with qualified partners to deliver parts ready for use.

Production That Matches Your Workflow

Custom manufacturers need suppliers that can adapt to changing demand without adding friction.

Wermke Spring supports:

Prototype and early-stage production
Small-batch and short-run manufacturing
Ongoing production with scheduled releases

There are no rigid minimum order quantities. Production is aligned to your needs so you can manage inventory, timelines, and customer commitments effectively.

We also prioritize responsive communication and reliable lead times so your projects keep moving.

A Reliable Extension of Your Supply Chain

You are responsible for delivering a complete, functional product to your customer. When that product requires a spring or wire form, you need a partner who can execute without added complexity.

Wermke Spring integrates into your process as a build-to-print manufacturing partner focused on precision, consistency, and dependable delivery.

If you have a drawing or specification that requires a custom spring or wire form, we invite you to submit it for review.

We’ll manufacture it to your requirements and deliver it ready for your next step.
