Welded Battery Lids
At Hermetic Seal Technology (HST), we specialize in providing top-notch welded battery lids that meet the stringent demands of various industries including healthcare, military, aerospace, electronics, and automotive sectors.
Here’s why our welded battery lids stand out:
- Expert Welding Capabilities: With our wealth of experience and expertise in hermetic welding and brazing, we deliver a diverse range of glass-to-metal seals tailored to your specific application needs.
- Precision Resistance Welding: Utilizing advanced resistance welding techniques, we seamlessly join glass-to-metal seals to battery lids while ensuring high hermeticity. Our meticulous attention to detail considers material types, component design, and welding parameters to prevent any damage to the seals during the welding process.
- Brazed Leak-Tight Assemblies: Beyond welding, HST excels in producing brazed leak-tight assemblies, offering flexibility in joining various components and materials with utmost precision.
- Stringent Quality Assurance: All our welded and brazed packages undergo rigorous 100% leak tests, guaranteeing hermeticity better than 1 x 10-8 cc/sec of helium. We meticulously inspect both the weld (or braze) and the glass-to-metal seal to ensure impeccable quality and reliability.
Production Capability
We have the ability to handle orders from ten parts to millions of parts.
We can also do sample parts HST can help you with free hermetic seal design and development to insurance you have a reliable and robust glass to metal seal.

Glass-to-Metal Seal Advantages
HST hermetic seals are hermetic (leak – tight) to isolate lithium batteries from external moisture and foreign contaminants to ensure long battery life
HST glass seals can resist extreme temperature and pressure variations while maintaining hermeticity. Our specially formulated glass materials have high corrosion resistance to lithium electrolytes eliminating glass corrosion which reduces shelf life.
Our “Clean-Seal” technology ensures the high quality of glass-to-metal parts that are free from oxidation and chemical residue that can effect welding and material corrosion resistance
