The custom fused quartz flanges is a high-performance precision component made from high-purity fused silica (SiO₂). It is widely used in demanding industrial environments where high temperature resistance, chemical stability, and vacuum sealing performance are required.
Compared with conventional metal flanges such as stainless steel or iron, quartz glass flanges provide superior thermal stability and chemical inertness. They do not deform easily under extreme temperatures and maintain excellent structural integrity even in corrosive or high-vacuum conditions.
Due to these advantages, fused quartz flanges are increasingly used in semiconductor manufacturing, plasma systems, optical equipment, and advanced scientific research instruments.
