Advanced Metal Sealing Solutions for Fusion and Accelerator Applications

Extreme Performance in Ultra-High Vacuum Conditions

In this case study, we highlight the capabilities of Sonkit’s zero-preload all-metal sealing solution, designed to meet the extreme demands of nuclear fusion reactors and particle accelerators. Our innovative seal achieved a leakage rate as low as 10E-12 Pa m³/s, far surpassing industry standards for sealing performance.

Reliability Under Extreme Temperatures and Radiation

Sonkit's composite all-metal seal is engineered to operate effectively in ultra-high vacuum (UHV) conditions and extreme temperatures ranging from -270°C to 500°C. The seal is also highly resistant to radiation, ensuring it can withstand prolonged exposure to intense radiation without degradation. With a self-adjusting, spring-energized design, the seal compensates for material wear and thermal expansion, ensuring consistent performance in challenging environments.

Precision Sealing for Advanced Materials

Developed to seal between polymer material flanges and stainless steel grooves, this solution addresses the unique sealing needs of materials like ceramics, plastics, aluminum alloys, and quartz. It can function with almost zero bolt preload, making it a reliable alternative to rubber and non-metallic seals in critical applications.

Optimized for High-Tech Industries

This technology is particularly suited for use in vacuum semiconductor systems, fusion reactors, and clean energy applications, ensuring long-term reliability and minimal maintenance even in the most demanding conditions. Sonkit’s all-metal seals provide the high-performance, low-leakage, and long-lasting reliability that these high-tech industries require.
