Our experience and expertise in hermetic welding plus brazing allows us to offer range of glass-to-metal seals for the healthcare, military, aerospace, electronic, and automotive industries. Using resistance welding we are able to hermetically join glass seals to metal surfaces. To ensure the high hermeticity of the seals, we take into consideration factors such as the type of materials used in the welding process and the temperature to which the glass seal is heated.

Our in-house welding and testing capabilities enable us to produce leak-tight hermetic assemblies. In addition to welded glass-to-metal seals, we also produce hermetically brazed assemblies. By hermetic brazing, HST manufactures leak-tight seals. Regardless of the processing approach we adopt, be it welding or brazing, all our hermetically sealed components are subject to 100% leak tests. We guarantee a hermeticity of 1 x 10-8 cc/sec on all our welded or brazed seals.
