Spring Energized C-Ring Metal Sealing Solution for Medical Equipment

In this case study, we showcase Sonkit's advanced metal sealing solution for medical equipment, designed to address the unique challenges of sealing critical components in demanding environments. Our solution achieved an impressive leakage rate of 10E-10 Pa m³/s under ultra-high vacuum testing, surpassing industry standards for ultra-low leakage.

Sonkit developed a spring-energized metal C-ring made from aluminum alloy with a racetrack shape, which provides reliable compression and deformation with minimal bolt tightening force. This seal ensures excellent performance in extreme conditions, including temperatures ranging from -270°C to 15°C and pressures from high vacuum to atmospheric pressure.

The seal's design also makes it highly resistant to corrosion, capable of withstanding exposure to corrosive chemicals, and ensures high purity with zero outgassing during long-term operation. The spring-energized feature compensates for material wear and thermal expansion, ensuring consistent performance over time.

Ideal for medical devices such as MRI machines, CT scanners, and proton therapy equipment, Sonkit's sealing solution provides enhanced reliability, high-performance sealing, and long-term stability in challenging environments, ensuring the safety and effectiveness of critical medical applications.
