From vibration isolation to controlled motion, sometimes the smallest component has a very specific problem to solve.

And that's exactly the kind of conversation we enjoy.

Two cities. Two shows. Lots of springs.

Our team is at MD&M Midwest today, and PODD starts tomorrow.

We're looking forward to seeing familiar faces, meeting new ones, and talking about what we do best.

Not every spring gets stronger as it moves.

Constant force springs can provide relatively consistent force over long travel distances.

Pretty clever for a strip of spring steel, right?

Our team will be at MD&M Midwest and PODD this week talking about applications just like these.

Some problems need a little twist... Literally!

Our spiral torsion springs help store and release rotational energy in compact mechanisms.

It's the kind of work that keeps our team thinking, building, and occasionally talking about springs a little too much.

Next week, our team is bringing the springs in our bags:

📍 MD&M Midwest | Booth 3621
📍 PODD Boston | Booth 213

Two shows. Plenty of spring conversations.

When one machine shakes, its neighbors shouldn't have to join in.

Wire rope vibration isolators help manage shock and vibration transmission in industrial equipment.

At John Evans' Sons, we know that protecting a system often starts with understanding how it moves.

Not all precision engineering looks like a spring. 🔧

John Evans' Sons also custom-manufactures Wire Forms, connectors, supports, and guides used in everything from retail product displays to medical devices like catheter guides and surgical instruments.

They can be custom-built and are CAD/CAM engineered, made to your exact spec.

Reach out to see what we can build for you!

Small parts, big impact.

At John Evans' Sons we specialized in micro springs and offers in-house prototyping to help bring your most space-constrained designs to life.

From concept to functional prototype, we offer precision at every scale.

Reach out and let's discuss custom solutions for your project!

Precision is not just about making the part. It is about taking responsibility for every detail along the way.

This month, we’re proud to recognize Jared Ickler, who has been part of John Evans’ Sons for nearly seven years.

Jared’s experience spans multiple areas of our operation, but his goal remains the same on every job: make sure the work meets the customer’s requirements.

When producing springs for surgical robotics applications, Jared has mastered the careful work of keeping parts organized and ensuring they are properly tested. His attention to detail, versatility, and customer-first mindset help make him someone the team can count on.

Thank you, Jared, for the skill and care you bring to every job!

Surgical robots, industrial automation, and even interplanetary rovers have something in common: John Evans' Sons engineers the precision springs behind these advanced robotics technologies 🤖

This is the proof that even the most cutting-edge systems rely on components with a 176-year track record.

PDA week is wrapped. Johnny Torsion is just getting warmed up. 🎙️

Headphones on. Bow tie ready. One very important question:

What happens when an autoinjector’s spring force changes during the injection?

Our podcast host joins Duane from John Evans’ Sons to explore spring force, formulation viscosity, storage conditions and why “we’ll fit the spring in later” deserves another look.

Watch the new One Spring at a Time: Mechanics of the Impossible episode. (the people and applications are real and the voices and host are ai. link in the comments)

Because sometimes, the smallest component has one of the biggest jobs.

One more day in Palm Springs. Plenty more to talk about. ☀️

Small springs bring big questions: How much force? How much travel? How little space?

Connect with us at PDA today. Bring your spring questions. We’re in our element.
