50 years?!

That's not a tenure. That's a legacy!!!

This week, we celebrated one of the people who makes Tollman Spring what it is — a true spring wizard who's seen it all, solved nearly all of it, and somehow still shows up ready to make something from nearly nothing.

🎉 Half a century of tight tolerances.
🎉 Half a century of "let me take a look at that."
🎉 Half a century of knowing exactly which wire, which form, which fix — before most of us even finished reading the print.

We honored him the right way: a getaway package to recharge, a whole lot of cake (and candles — many birthdays to celebrate this month as well), and our annual summer kickoff picnic with the team that's proud to work beside him.

Tollman Spring has always been built on expertise you can't just hire. You grow it. You earn it.

Congrats to a craftsman, a mentor, and a spring wizard of the highest order!

Happy Birthday to our team members celebrating in June, and here's to the best annual summer kickoff!

420 suppliers in the dataset.

One had the lowest PPM rejection rate and walked away with Best Supplier Quality.

That was Tollman Spring.

PPM — parts per million — is one of the most demanding quality benchmarks in manufacturing. Fewest defects per million parts produced, across the entire supplier pool, earned us Best Supplier Quality from a customer with nearly $1B in annual revenue.

Two years ago, that same customer named us Supplier of the Year.

Precision isn't something we turn on for high-visibility accounts.

It's built into every order, every run, every part.

How many tmes will you pump the suncreen bottle and reapply?

Each pump works because of one tiny spring.

You're welcome! 😜 🧴

Micro springs show up everywhere summer happens:

☀️ Sunscreen and spray pump dispensers
☀️ Hose nozzle triggers
☀️ Cooler latches and folding chair mechanisms

Tollman Spring specializes in micro springs and precision helical springs, manufactured to ISO 9001:2015.

Small parts. Big summer.

Reapply every two hours. The spring can handle it.

What's the most underrated piece of summer gear? 👇

It's Friday at Tollman Spring, and Jonathon is doing what he does best: making the tools that make your parts.

Wire EDM lets us cut hardened tool steel into features with tolerances tighter than a Friday afternoon deadline. The tooling Jonathon builds here is what keeps our micro springs, wire forms, and stampings hitting spec, run after run.

Precision starts long before the first coil is wound. It starts in the toolroom.

Happy Friday from the team that sweats the small stuff. Literally. Our springs are tiny.

Failure isn't an option.

That's the reality for many defense applications—and it's why even the smallest components matter.

Helical springs help control motion, store energy, and deliver repeatable performance in critical systems. Whether they're supporting firing mechanisms, actuators, or other precision assemblies, they need to perform exactly as intended every time they're called upon.

🔹 Consistent force
🔹 Reliable performance
🔹 Precision manufacturing
🔹 Quality you can trust

At Tollman Spring, every coil is built with those expectations in mind.
Because when performance matters most, details matter most.

💬 Engineers: What's the first thing you look at when designing for reliability in a high-stakes application?

Monday energy: a full skid of magazine springs ready to ship.

Thousands of parts. One job. Absolute consistency.

These feed springs have to perform the same way every single time—cycle one through cycle ten thousand. No drift. No surprises. No excuses.

That’s where precision matters most: wire diameter, pitch, end configuration. Small details, big impact over time.

Get it right and everything runs smooth in the field.
Get it wrong and you find out the hard way.

Stacked. Sorted. Shipping out.
Fit to Function. Built by Tollman Spring.

That micro compression spring is sitting on a 1980 Lincoln penny.

For scale, the word "LIBERTY" is wider than the spring itself—kind of like the gap between "this should fit" and "why isn't it fitting?" 😅

When you're working at this size, every coil matters and every thousandth of an inch can make the difference between success and a redesign.

That's why precision isn't just important—it's everything!

At Tollman Spring, we build springs for applications where "small" is measured in fractions of fractions. 💪

High-performing parts aren’t enough unless they can perform the exact same way 10,000 times.

At Tollman, we build consistency into every process — material selection, forming, heat treatment, automated inspection, and statistical process control.

For OEMs managing tight performance windows... that consistency reduces scrap, warranty risk, and line stoppages.

We provide the stability and repeatability teams count on when scaling critical components.

Built to Perform. Designed to Endure.

Extension springs are essential components used to absorb and store energy while resisting pulling forces. From medical devices and aerospace systems to industrial automation and EV applications, these springs help deliver smooth, reliable motion and controlled tension.

At Tollman Spring, we manufacture custom extension springs engineered for durability, precision, and long-lasting performance.

Our capabilities include:

✔ Custom hook and loop configurations
✔ Stainless steel, music wire, and specialty alloys
✔ Pre-load and initial tension options
✔ Secondary operations including coating, plating, and stress relieving

No matter the application, our engineering and manufacturing teams work closely with customers to develop reliable spring solutions tailored to their exact requirements.

Have a challenging application? Let’s talk.

🤖 A robot is only as repeatable as its smallest moving part.

Every actuator.
Every gripper.
Every sensor mechanism.
Every return cycle.

Millions of movements depend on components that maintain geometry under load — without drift, fatigue, or loss of tension.

And when a spring fails to hold tolerance?
📉 Repeatability slips.
📉 Calibration drifts.
📉 Entire processes wander out of spec.

That’s why Tollman Spring engineers helical springs, micro springs, and wire forms built for real-world robotic performance. ⚙️

From compact actuator packages to precision contact mechanisms inside grippers and sensors, our components are designed to deliver:

✔️ Tight coil geometry
✔️ Consistent cycle performance
✔️ Precision return force
✔️ Compact fit-to-function designs
✔️ Reliability over millions of cycles

Because in robotics, the smallest component can determine whether a system performs flawlessly… or slowly falls out of tolerance.

🚀 Designing motion systems for robotics or automation?
That’s a conversation worth having before the prototype — not after.
