Bal Seal Engineering

Three jobs. One spring.
When every component in your semiconductor equipment has to earn its place, multifunctionality matters. A Bal Spring® canted coil spring doesn't just shield against EMI/RFI, it also delivers reliable electrical grounding and mechanically connects with precise, controllable forces.

That means fewer parts, simpler assemblies, easier maintenance, and more reliable equipment. Check out the infographic to see how this 3-in-1 technology is helping fab and test equipment designers do more with less.

As LC pressures continue to rise, the Enduris high-pressure sealing system helps you stay ahead of the curve. Combining proven Bal Spring canted coil spring technology, an advanced, media-resistant polymer jacket formulation, and a precision backup element, Enduris delivers reliable sealing performance at pressures of 20,000 psi and beyond.

How can a simple spring take your semiconductor equipment designs to the next level? By delivering more than EMI/RFI shielding.

Our Bal Spring is a precision-engineered 3-in-1 solution that combines exceptional EMI/RFI shielding with electrical conductivity and mechanical retention in a single component. The result? Fewer parts, simpler assemblies, easier maintenance, improved reliability, and more equipment uptime.

If your current shielding tech can't do all that, it may be time to think about a spring. See ours in action: https://www.balseal.com/spring/shielding/

In a field that never stops advancing, standing still isn't an option. That's why we're at the AIMD Worskhop in Delft this week, supporting the community, sharing knowledge, and learning from the innovators defining the next generation of active implantable medical devices.

Longer maintenance intervals start with smarter sealing strategy.
This blog examines how the right seal geometry, materials, rinse systems, and hardware tolerances can help prevent premature pump failure, reduce leakage, and extend the life of critical IVD equipment. If you’re designing for accuracy, uptime, and reliability, it’s worth a look.

Long before the factory floor, the lab, or the launch pad, there's a first spark of interest in engineering. That’s why we’re proud to support Mater Dei High School’s Varsity Robotics Team during the 2025–26 FIRST Robotics Competition season. With the help of sponsors, mentors, and countless hours of hard work, they advanced to the playoffs in two competitions this year.
Congratulations to these talented young engineers and problem-solvers. We can’t wait to see what you build next.

Heat is the enemy. But bulk isn’t always the best defense.
The Bal Spring canted coil spring flips the script, moving heat away from critical interfaces without grease, ceramics, sinks, or oversized hardware. The same design that helps it keep its cool in electrical conducting applications is a built-in pathway that lets you do thermal management your way. Put a spring in your toolbox:

This wall in our Engineering area says it best: DRIVEN to solve, built to INNOVATE. And more often than not, we’re the team customers turn to when the “standard solution” isn’t cutting it.

Tight tolerances? Harsh environments? Conflicting requirements? That’s where things get interesting.

If you’ve got a challenge that’s bending the rules, we’re probably already leaning into it. Put us to work: https://www.balseal.com/design-request-form/
