Lithium Battery Seals



Hermetic Seal Technology (HST) has been setting the standards for custom glass-to-metal seals, especially lithium battery seals, since 1994. We have specially formulated Lithium corrosion resistant glass to greatly reduce corrosion and to isolate lithium electrolytes, such as lithium / manganese dioxide (LiMnO2), lithium / sulfur dioxide (Li/SO2), and lithium / thionyl chloride (Li/SOCl2) in lithium-ion batteries, from foreign agents. HST lithium battery seals can withstand corrosive chemicals, electrical variations, as well as extreme temperatures to give your battery a long shelf life.

For high performance lithium batteries, we fabricate reliable hermetic seals from high-conductivity pin materials, exotic alloys and"both ...

Medical & Titanium Battery Seals



For the healthcare industry, we custom design and manufacture a unique line of medical equipment titanium seals. HST specializes in manufacturing glass-to-metal seals for lithium batteries used in medical implantable devices such as pacemakers, heart defibrillators, drug-delivery systems, portable diagnostic equipment, and pumps. Unlike conventional glass sealing processes, our manufacturing process does not involve chemical oxide removal processes. Our production processes are also free from the carburization process that weakens the corrosion resistant capabilities of the seal’s housing. With clean seal technology, we make ready-to-install glass seals that do not require any post machining.

We efficiently seal ...
welded-and-brazed

Welded & Brazed Parts



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 ...
high-amperage-feedthrus

High Amperage Feedthrus



At HST, we engineer glass-to-metal seals/feedthrus in different specifications to meet varied high amperage needs. Pins for these feedthrus are made from hermetically sealable materials, such as alloy 52, stainless steel, molybdenum, copper-cored 52 alloy, and copper cored stainless steel.

Our high amperage seals are used in electric vehicles and high output batteries, as well as in several high current switching applications. Our engineers can design as well as build feedthrus to custom specifications, facilitating easy mounting.
